  • sending parameters with ajax

    - by kawtousse
    I am trying to send parameters that I get from a table in my jsp to other JSP using ajax. I am using the followinf function to send all values to JSP: ajaxForm but I don't know why the send failed every time I run it: Here is the javascript function: function editarow() { var xhr = getXhr(); xhr.onreadystatechange = function() { if (xhr.readyState == 4 && xhr.status == 200) { selects = xhr.responseText; // On se sert de innerHTML pour rajouter les options a la liste document.getElementById('prjsel').innerHTML = selects; } }; var row, firstNameCell, lastNameCell; var table = document.getElementById("sheet"); var buttons = table.getElementsByTagName("button"); for (var i = 0; i < buttons.length; i++) { if (buttons[i].name == "edit") { buttons[i].onclick = function() { row = this.parentNode.parentNode; // The first name cell is the first child NameCell1 = findElement(row.firstChild); NameCell2 = findElement(NameCell1.nextSibling); NameCell3 = findElement(NameCell2.nextSibling); NameCell4 = findElement(NameCell3.nextSibling); NameCell5 = findElement(NameCell4.nextSibling); NameCell6 = findElement(NameCell5.nextSibling); NameCell7 = findElement(NameCell6.nextSibling); // `innerHTML` pour obtenir la valeur /*alert("name 1 is " + NameCell1.innerHTML); alert("name 2 is " + NameCell2.innerHTML); alert("name 3 is " + NameCell3.innerHTML); alert("name 4 is " + NameCell4.innerHTML); alert("name 5 is " + NameCell5.innerHTML); alert("name 6 is " + NameCell6.innerHTML); alert("name 7 is " + NameCell7.innerHTML);*/ } } } xhr.open("POST", "ajaxForm.jsp", true); xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xhr.send("NameCell1="+NameCell1,"NameCell2="+NameCell2,"NameCell3="+NameCell3,"NameCell4="+NameCell4,"NameCell5="+NameCell5,"NameCell6="+NameCell6,"NameCell7="+NameCell7 ); } After I get the value from the table I want to send all of them to the ajaxForm.jsp.

  • UITableView, having problems changing accessory when selected

    - by zpasternack
    I'm using a UITableView to allow selection of one (of many) items. Similar to the UI when selecting a ringtone, I want the selected item to be checked, and the others not. I would like to have the cell selected when touched, then animated back to the normal color (again, like the ringtone selection UI). A UIViewController subclass is my table's delegate and datasource (not UITableViewController, because I also have a toolbar in there). I'm setting the accessoryType of the cells in cellForRowAtIndexPath:, and updating my model when cells are selected in didSelectRowAtIndexPath:. The only way I can think of to set the selected cell to checkmark (and clear the previous one) is to call [tableView reloadData] in didSelectRowAtIndexPath:. However, when I do this, the animating of the cell deselection is weird (a white box appears where the cell's label should be). If I don't call reloadData, of course, the accessoryType won't change, so the checkmarks won't appear. I suppose I could turn the animation off, but that seems lame. I also toyed with getting and altering the cells in didSelectRowAtIndexPath:, but that's a big pain. Any ideas? Abbreviated code follows... - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell* aCell = [tableView dequeueReusableCellWithIdentifier:kImageCell]; if( aCell == nil ) { aCell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:kImageCell]; } aCell.text = [imageNames objectAtIndex:[indexPath row]]; if( [indexPath row] == selectedImage ) { aCell.accessoryType = UITableViewCellAccessoryCheckmark; } else { aCell.accessoryType = UITableViewCellAccessoryNone; } return aCell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:YES]; selectedImage = [indexPath row] [tableView reloadData]; }

  • How does PHP PDO work internally ?

    - by Rachel
    I want to use pdo in my application, but before that I want to understand how internally PDOStatement->fetch and PDOStatement->fetchAll. For my application, I want to do something like "SELECT * FROM myTable" and insert into csv file and it has around 90000 rows of data. My question is, if I use PDOStatement->fetch as I am using it here: // First, prepare the statement, using placeholders $query = "SELECT * FROM tableName"; $stmt = $this->connection->prepare($query); // Execute the statement $stmt->execute(); var_dump($stmt->fetch(PDO::FETCH_ASSOC)); while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) { echo "Hi"; // Export every row to a file fputcsv($data, $row); } Will after every fetch from database, result for that fetch would be store in memory ? Meaning when I do second fetch, memory would have data of first fetch as well as data for second fetch. And so if I have 90000 rows of data and if am doing fetch every time than memory is being updated to take new fetch result without removing results from previous fetch and so for the last fetch memory would already have 89999 rows of data. Is this how PDOStatement::fetch works ? Performance wise how does this stack up against PDOStatement::fetchAll ?

  • Select Table Rows by Grouping them Adjacent to each Other using XPath

    - by Adnan Yaseen
    I am not clear how to express my problem correctly in the question so forgive me if I am not able to properly convey my problem. I have following data. <tr class="header">Random Value 1</tr> <tr class="item">1</tr> <tr class="item">2</tr> <tr class="item">3</tr> <tr class="header">Random Value 2</tr> <tr class="item">4</tr> <tr class="item">5</tr> <tr class="item">6</tr> <tr class="header">Random Value 3</tr> <tr class="item">7</tr> <tr class="item">8</tr> <tr class="item">9</tr> What I want to acheive is that I want to select the with class header. I have achieved this by using the following line of code, HtmlNodeCollection headerNodes = doc.DocumentNode.SelectNodes("//tr[@class='header']"); Now I have all the header rows in the collection. Now I loop through all the header nodes and I want to get the table rows which are adjacent to the respective header rows. foreach (HtmlNode node in headerNodes) { HtmlNodeCollection itemNodes = ??? } My question is that what I should write here so that for header row with text "Random Value 1" I get the item rows 1,2 and 3. Similarly for header row with text "Random Value 2" I get the item row 4,5 and 6 and so on.

  • Zend Framework Relationships - findDependentRowset

    - by Morten Nielsen
    Hello, When I call the method findDependentRowset, the returning rowset contains all the rows in the dependent table, and not only the rowsets that matches the reference. Hoping someone could explain this, since I was of the assumption that findDependentRowset would only return rowset matching my 'rule'? I have the following DbTable Models: class Model_DbTable_Advertisement extends Zend_Db_Table_Abstract { protected $_name = 'Advertisements'; protected $_primary = 'Id'; protected $_dependentTables = array ( 'Model_DbTable_Image', ); } class Model_DbTable_Image extends Zend_Db_Table_Abstract { protected $_name = 'Images'; protected $_primary = 'Id'; protected $_referenceMap = array( 'Images' => array( 'column' => 'AdvertisementId', 'refColumn' => 'Id', 'refTableClass' => 'Model_DbTable_Advertisement', ) ); } Now when i execute the following: (Simplified for Question sake) $model = new Model_DbTable_Advertisement(); $rowSet = $model->fetchAll(); $row = $rowSet->current(); $dRow = $row->findDependentRowset('Model_DbTable_Image'); I would expect $dRow to only contain 'Images' that has the same advertisementId as $row, but instead i receive all rows in the Images table. Any help appriciated. Kind regards, Morten

  • PHP mySQL Error

    - by happyCoding25
    Hello, Im new to php so I decided to follow this tutorial for a simple login screen. I got the code setup but when I try login I get this error: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in (a long file path to the script) on line 27 The code I got from the tutorial is: <?php ob_start(); $host="thehost"; // Host name $username="myusername"; // Mysql username $password="mypass"; // Mysql password $db_name="test"; // Database name $tbl_name="members"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // Define $myusername and $mypassword $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); header("location:login_success.php"); } else { echo "Wrong Username or Password"; } ob_end_flush(); ?> (Note: All of the mySQL database info is filled in on my version) Aslo, the author gives a php5 version and a normal php version. I have tried both and gotten the same error. If anyone knows why this is happening help is really appreciated.

  • Python DictReader - Skipping rows with missing columns?

    - by victorhooi
    heya, I have a Excel .CSV file I'm attempting to read in with DictReader. All seems to be well, except it seems to omit rows, specifically those with missing columns. Our input looks like: mail,givenName,sn,lorem,ipsum,dolor,telephoneNumber [email protected],ian,bay,3424,8403,2535,+65(2)34523534545 [email protected],mike,gibson,3424,8403,2535,+65(2)34523534545 [email protected],ross,martin,,,,+65(2)34523534545 [email protected],david,connor,,,,+65(2)34523534545 [email protected],chris,call,3424,8403,2535,+65(2)34523534545 So some of the rows have missing lorem/ipsum/dolor columns, and it's just a string of commas for those. We're reading it in with: def read_gd_dump(input_file="blah 20100423.csv"): gd_extract = csv.DictReader(open('blah 20100423.csv'), restval='missing', dialect='excel') return dict([(row['something'], row) for row in gd_extract]) And I checked that "something" (the key for our dict) isn't one of the missing columns, I had originally suspected it might be that. It's one of the columns after that. However, DictReader seems to completely skip over the rows. I tried setting restval to something, didn't seem to make any difference. I can't seem to find anything in Python's CSV docs (http://docs.python.org/library/csv.html) that would explain this behaviour, but I may have misread something. Any ideas? Thanks, Victor

  • QTableWidget::itemAt() returns seemingly random items

    - by Jordan Milne
    I've just started using Qt, so please bear with me. When I use QTableWidget-getItemAt(), it returns a different item from if I used currentItemChanged and clicked the same item. I believe it's necessary to use itemAt() since I need to get the first column of whatever row was clicked. Some example code is below: MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); QList<QString> rowContents; rowContents << "Foo" << "Bar" << "Baz" << "Qux" << "Quux" << "Corge" << "Grault" << "Garply" << "Waldo" << "Fred"; for(int i =0; i < 10; ++i) { ui->tableTest->insertRow(i); ui->tableTest->setItem(i, 0, new QTableWidgetItem(rowContents[i])); ui->tableTest->setItem(i, 1, new QTableWidgetItem(QString::number(i))); } } //... void MainWindow::on_tableTest_currentItemChanged(QTableWidgetItem* current, QTableWidgetItem* previous) { ui->lblColumn->setText(QString::number(current->column())); ui->lblRow->setText(QString::number(current->row())); ui->lblCurrentItem->setText(current->text()); ui->lblCurrentCell->setText(ui->tableTest->itemAt(current->column(), current->row())->text()); } For the item at 1x9, lblCurrentItem displays "9" (as it should,) whereas lblCurrentCell displays "Quux". Am I doing something wrong?

  • How to join a table in symfony (Propel) and retrieve object from both table with one query

    - by Jean-Philippe
    Hi, I'm trying to get an easy way to fetch data from two joined Mysql table using Propel (inside Symfony) but in one query. Let's say I do this simple thing: $comment = CommentPeer::RetrieveByPk(1); print $comment->getArticle()->getTitle(); //Assuming the Article table is joined to the Comment table Symfony will call 2 queries to get that done. The first one to get the Comment row and the next one to get the Article row linked to the comment one. Now, I am trying to find a way to make all that within one query. I've tried to join them using $c = new Criteria(); $c->addJoin(CommentPeer::ARTICLE_ID, ArticlePeer::ID); $c->add(CommentPeer::ID, 1); $comment = CommentPeer::doSelectOne($c); But when I try to get the Article object using $comment->getArticle() It will still issue the query to get the Article row. I could easily clear all the selected columns and select the columns I need but that would not give me the Propel object I'd like, just an array of the query's raw result. So how can I get a populated propel object of two (or more) joined table with only one query? Thanks, JP

    I have a Table View, and CharTableController, the CharTableController works like this: .h: #import <Foundation/Foundation.h> @interface CharTableController : UITableViewController <UITableViewDelegate, UITableViewDataSource>{ // IBOutlet UILabel *debugLabel; NSArray *listData; } //@property (nonatomic, retain) IBOutlet UILabel *debugLabel; @property (nonatomic, retain) NSArray *listData; @end The .m: #import "CharTableController.h" @implementation CharTableController @synthesize listData; - (void)viewDidLoad { NSArray *array = [[NSArray alloc] initWithObjects:@"Sleepy", @"Sneezy", @"Bashful", @"Happy", @"Doc", @"Grumpy", @"Dopey", @"Thorin", @"Dorin", @"Nori", @"Ori", @"Balin", @"Dwalin", @"Fili", @"Kili", @"Oin", @"Gloin", @"Bifur", @"Bofur", @"Bombur", nil]; self.listData = array; [array release]; [super viewDidLoad]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.listData count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.textLabel.text = [listData objectAtIndex:row]; } return cell; } @end And I Use the IB to link the TableView's dataSource and delegate to the CharTableController. In the CharTableController's view is the TableView in IB obviously. Reference Object in dataSource TableView and delegate TableView. What's wrong with my setting? thz.

  • Best way to store list of numbers and to retrieve them

    - by bingoNumbers
    Hi. What is the best way to store a list of random numbers (like lotto/bingo numbers) and retrieve them? I'd like to store on a Database a number of rows, where each row contains 5-10 numbers ranging from 0 to 90. I will store a big number of those rows. What I'd like to be able is to retrieve the rows that have at least X number in common to a newly generated row. Example: [3,4,33,67,85,99] [55,56,77,89,98,99] [3,4,23,47,85,91] Those are on the DB I will generate this: [1,2,11,45,47,88] and now I want to get the rows that have at least 1 number in common with this one. The easiest (and dumbest?) way is to make 6 select and check for similar results. I thought to store numbers with a large binary string like 000000000000000000000100000000010010110000000000000000000000000 with 99 numbers where each number represent a number from 1 to 99, so if I have 1 at the 44th position, it means that I have 44 on that row. This method is probably shifting the difficult tasks to the Db but it's again not very smart. Any suggestion?

  • MySQL: order by and limit gives wrong result

    - by Larry K
    MySQL ver 5.1.26 I'm getting the wrong result with a select that has where, order by and limit clauses. It's only a problem when the order by uses the id column. I saw the MySQL manual for LIMIT Optimization My guess from reading the manual is that there is some problem with the index on the primary key, id. But I don't know where I should go from here... Question: what should I do to best solve the problem? Works correctly: mysql> SELECT id, created_at FROM billing_invoices WHERE (billing_invoices.account_id = 5) ORDER BY id DESC ; +------+---------------------+ | id | created_at | +------+---------------------+ | 1336 | 2010-05-14 08:05:25 | | 1334 | 2010-05-06 08:05:25 | | 1331 | 2010-05-05 23:18:11 | +------+---------------------+ 3 rows in set (0.00 sec) WRONG result when limit added! Should be the first row, id - 1336 mysql> SELECT id, created_at FROM billing_invoices WHERE (billing_invoices.account_id = 5) ORDER BY id DESC limit 1; +------+---------------------+ | id | created_at | +------+---------------------+ | 1331 | 2010-05-05 23:18:11 | +------+---------------------+ 1 row in set (0.00 sec) Works correctly: mysql> SELECT id, created_at FROM billing_invoices WHERE (billing_invoices.account_id = 5) ORDER BY created_at DESC ; +------+---------------------+ | id | created_at | +------+---------------------+ | 1336 | 2010-05-14 08:05:25 | | 1334 | 2010-05-06 08:05:25 | | 1331 | 2010-05-05 23:18:11 | +------+---------------------+ 3 rows in set (0.01 sec) Works correctly with limit: mysql> SELECT id, created_at FROM billing_invoices WHERE (billing_invoices.account_id = 5) ORDER BY created_at DESC limit 1; +------+---------------------+ | id | created_at | +------+---------------------+ | 1336 | 2010-05-14 08:05:25 | +------+---------------------+ 1 row in set (0.01 sec) Additional info: explain SELECT id, created_at FROM billing_invoices WHERE (billing_invoices.account_id = 5) ORDER BY id DESC limit 1; +----+-------------+------------------+-------+--------------------------------------+--------------------------------------+---------+------+------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+------------------+-------+--------------------------------------+--------------------------------------+---------+------+------+-------------+ | 1 | SIMPLE | billing_invoices | range | index_billing_invoices_on_account_id | index_billing_invoices_on_account_id | 4 | NULL | 3 | Using where | +----+-------------+------------------+-------+--------------------------------------+--------------------------------------+---------+------+------+-------------+

  • Set the selected item for a combobox in a datagrid

    - by JingJingTao
    I am using a datagrid which has many combobox fields in it, when I click the datagrid combobox the selected item or highlighted value is the last item in the list, but I would like it to highlight the first(top) item in the list. I know for just a combobox, all I need to do is change the combobox.selecteditem or combobox.selectedindex, but I'm not sure what to do in this case. I have binded the combobox to a table in the database and used a datatable to store the combobox values and then I add a row to the datatable, I think the reason the last item in the combobox is highlighted is because I added a row to the datatable. Thank you for your help. String strGetTypes = "SELECT holidaycodeVARCHAR4Pk, codedescVARCHAR45 FROM holidaytype ORDER BY holidaycodeVARCHAR4Pk Desc"; DataTable dtHolidayType = new DataTable(); MySqlDataAdapter dbaElements = new MySqlDataAdapter(strGetTypes, ShareSqlSettings.dbConnect); dbaElements.Fill(dtHolidayType); DataGridViewComboBoxCell cboxDays = new DataGridViewComboBoxCell(); cboxDays.DataSource = dtHolidayType; cboxDays.DisplayMember = "codedescVARCHAR45"; cboxDays.ValueMember = "holidaycodeVARCHAR4Pk"; //Blank row dtHolidayType.Rows.Add(1); // gridDailyEmp.Rows[j].Cells[day] = cboxDays;

  • ploting 3d graph in matlab?

    - by lytheone
    Hello, I am currently a begineer, and i am using matlab to do a data analysis. I have a a text file with data at the first row is formatted as follow: time;wave height 1;wave height 2;....... I have column until wave height 19 and rows total 4000 rows. Data in the first column is time in second. From 2nd column onwards, it is wave height elevation which is in meter. At the moment I like to ask matlab to plot a 3d graph with time on the x axis, wave elevation on the y axis, and wave elevation that correspond to wave height number from 1 to 19, i.e. data in column 2 row 10 has a let say 8m which is correspond to wave height 1 and time at the column 1 row 10. I have try the following: clear; filename='abc.daf'; path='C:\D'; a=dlmread([path '\' filename],' ', 2, 1); [nrows,ncols]=size(a); t=a(1:nrows,1);%define t from text file for i=(1:20), j=(2:21); end wi=a(:,j); for k=(2:4000), l=k; end r=a(l,:); But everytime i use try to plot them, the for loop wi works fine, but for r=a(l,:);, the plot only either give me the last time data only but i want all data in the file to be plot. Is there a way i can do that. I am sorry as it is a bit confusing but i will be very thankful if anyone can help me out. Thank you!!!!!!!!!!

  • MSIE8 compatibility mode not rendering dynamically created table

    - by KristoferA - Huagati.com
    A bit weird... ...if running in IE8 quirks mode, the table added by the following code doesn't render. Can anyone tell me why, because it is not obvious to me..? <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script> function AddTable() { var table = document.createElement('table'); var row = document.createElement('tr'); table.appendChild(row); var cell = document.createElement('td'); cell.innerHTML='abc'; row.appendChild(cell); var divContainer = document.getElementById('divContainer'); divContainer.appendChild(table); } </script> </head> <body> <div id='divContainer'> </div> <input type='button' value='add table' onclick='javascript:AddTable()' /> </body> </html>

  • Dimension Mismatch MatLab; cant figure out why it is mismatching

    - by Abid
    I think it may be a syntax issue, here is the code. load ([ 'C:\Users\Abid\Desktop\Inquiry Runs\dtS' ]) dtS((dtS==0))=nan; for j=2:9; maxS=max(dtS(j,:)); minS=min(dtS(j,:)); maxval(j,:)=dtS((dtS>(maxS-.1*maxS))); minval(j,:)=dtS((dtS<(minS+.1*minS))); avmax(j)=mean(maxval(j,:)); avmin(j)=mean(minval(j,:)); avs(j,:)=[avmax(j) avmin(j)] end So I know the the row matrices are different sizes every loop. For example maxval(j,:) will change depending one row it is looking through for certain values. I did this manually and I see that on the first loop the matrices are size (1,1), however, if I set the loop to run for only j=2, the row length is 13. Usually if a matrix is changing size on the loop, I only get a warning, but this time I think it is due to a reason I don't understand.

  • Advanced ASP.NET Gridview Layout

    - by chief7
    So i had a feature request to add fields to a second table row for a single data row on a GridView. At first, I looked at extending the functionality of the GridView but soon realized this would be a huge task and since I consider this request a shim for a larger future feature decided against it. Also want to move to MVC in the near future and this would be throw away code. So instead I created a little jquery script to move the cell to the next row in the table. $(document).ready(function() { $(".fieldAttributesNextRow").each(function() { var parent = $(this).parent(); var newRow = $("<tr></tr>"); newRow.attr("class", $(parent).attr("class")); var headerRow = $(parent).parent().find(":first"); var cellCount = headerRow.children().length - headerRow.children().find(".hide").length; newRow.append($(this).attr("colspan", cellCount)); $(parent).after(newRow); }) }); What do you think of this? Is this a poor design decision? I am actually quite pleased with the ease of this solution. Please provide your thoughts.

  • question about MySQL database migration

    - by WilliamLou
    Hi there: If I have a MySQL database with several tables on a live server, now I would like to migrate this database to another server. Of course, the migration I mean here involves some database tables, for example: add some new columns to several tables, add some new tables etc.. Now, the only method I can think of is to use some php/python(two scripts I know) script, connect two databases, dump the data from the old database, and then write into the new database. However, this method is not efficient at all. For example: in old database, table A has 28 columns; in new database, table A has 29 columns, but the extra column will have default value 0 for all the old rows. My script still needs to dump the data row by row and insert each row into the new database. Is there any tools or a better method than writing a script yourself? Here, I dont need to worry about multithread writing problems etc.., I mean the old database will be down (not open to public usage etc.., only for upgrade ) for a while. Thanks!!

    I'm using Json to retrieve data from a database, construct some html, and put it to the page, but I'm getting a syntax error after my tag, which is the last tag in the string from my php file. PHP if($QString == ""){ $query = "SELECT * FROM categories"; $result = mysql_query($query); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $categories="<a href=" . '"' .
