  • filling a form with parameter already selected using ajax

    - by kawtousse
    hi every one, My goal untill now is to fill a form with values from a table (html table). it is a kind of refreshing the form. so the user who wants to modify the html table through the form must prefill the form with values wich he already selected. I used the DOM to acces to each row and cell in the table and i used ajax to pass parameter to other jsp. but Iam confused what shall be the next step to fill the form.

    - by Sam
    I have a query that gets a list of emails who have subscribed for a newsletter trial which lasts 30 days.. $thirty = time() - 3024000; SELECT c.email FROM tbl_clients AS c JOIN tbl_clientoptions AS o ON o.client = c.id WHERE o.option = 'newsletter' AND c.datecreated $thirty What I want to do is do a check in that same query so it also returns clients OVER 30 days old if they have the tbl_clientoptions.option = 'trialoverride' (ie; a row in the client options table with the value "trialoverride") basic columns are: TBL_CLIENTS id,name,email,datecreated TBL_CLIENTOPTIONS id,client,option

  • Is there any alternative way of writing this switch statement(C#3.0)

    - by Newbie
    Can it be done in a better way public static EnumFactorType GetFactorEnum(string str) { Standardization e = new Standardization(); switch (str.ToLower()) { case "beta": e.FactorType = EnumFactorType.BETA; break; case "bkp": e.FactorType = EnumFactorType.BOOK_TO_PRICE; break; case "yld": e.FactorType = EnumFactorType.DIVIDEND_YIELD; break; case "growth": e.FactorType = EnumFactorType.GROWTH; break; case "mean": e.FactorType = EnumFactorType.MARKET_CAP; break; case "momentum": e.FactorType = EnumFactorType.MOMENTUM; break; case "size": e.FactorType = EnumFactorType.SIZE; break; case "stat_fact1": e.FactorType = EnumFactorType.STAT_FACT_1; break; case "stat_fact2": e.FactorType = EnumFactorType.STAT_FACT_2; break; case "value": e.FactorType = EnumFactorType.VALUE; break; } return e.FactorType; } If I create a Static class(say Constatant) and declare variable like public static string BETA= "beta"; and then if I try to put that in the Case expression like Case Constants.BETA : e.FactorType = EnumFactorType.BETA; break; then the compiler will report error.(quite expected) So is there any other way?(I canot change the switch statement) Using C#3.0 Thanks

  • How to hook onclick event for each cell in a table in Javascript?

    - by MartyIX
    I was thinking if there's a better solution for adding onclick handler to each cell in a table than this approach: http://stackoverflow.com/questions/1207939/adding-an-onclick-event-to-a-table-row Better in the way that I wouldn't need to set "cell.onclick = function" for each cell. I just need to get the coordinations of a cell where user clicked. Thanks!

  • Why does java.util.concurrent.ArrayBlockingQueue use 'while' loops instead of 'if' around calls to

    - by theFunkyEngineer
    I have been playing with my own version of this, using 'if', and all seems to be working fine. Of course this will break down horribly if signalAll() is used instead of signal(), but if only one thread at a time is notified, how can this go wrong? Their code here - check out the put() and take() methods; a simpler and more-to-the-point implementation can be seen at the top of the JavaDoc for Condition. Relevant portion of my implementation below. public Object get() { lock.lock(); try { if( items.size() < 1 ) hasItems.await(); Object poppedValue = items.getLast(); items.removeLast(); hasSpace.signal(); return poppedValue; } catch (InterruptedException e) { e.printStackTrace(); return null; } finally { lock.unlock(); } } public void put(Object item) { lock.lock(); try { if( items.size() >= capacity ) hasSpace.await(); items.addFirst(item); hasItems.signal(); return; } catch (InterruptedException e) { e.printStackTrace(); } finally { lock.unlock(); } } P.S. I know that generally, particularly in lib classes like this, one should let the exceptions percolate up.

  • Generic object comparison diff routine

    - by MicMit
    The question stems from database tables comparison. Let's say we put left row in the instance Left and the right one into instance Right of the same type. And we'got many tables and respective types. How to implement more or less generic routine resulting in a collection of diffs e.g. propertyName , leftValue , rightValue for each such a pair of instances of the same type.

  • Simple syntax question

    - by stabby
    Hey everyone, First off, sorry for my noob-ness. Believe me when i say ive been rtfm'ing. Im not lazy, im just dumb (apparently). On the bright side, this could earn someone some easy points here. I'm trying to do a match/replace with a pattern that contains special characters, and running into syntax errors in a Flex 3 app. I just want the following regex to compile... (while also replacing html tags with "") value.replace(/</?\w+((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)/?>/g, ""); On a side note, the pattern /<.*?/g wouldn't work in cases where there are html entities between tags, like so: <TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0"><one</FONT> </P> </TEXTFORMAT><TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0">two</FONT> </P> </TEXTFORMAT> The first regex would get both "<one" and "two", but the second would only get "hi" Thanks!

  • finding if an anniversary is coming up in n days in MySql

    - by user151841
    I have a table with anniversary dates. I want a query that returns me rows of anniversaries coming up in the next 10 days. For instance: birthdate --------- 1965-10-10 1982-05-25 SELECT birthdate FROM Anniversaries WHERE mystical_magical_mumbo_jumbo <= 10 +------------+ | birthdate | +------------+ | 1982-05-25 | +------------+ 1 row in set (0.01 sec) I'd like to keep the query in the form x <= 10, because I'll use that number 10 in other parts of the query, and if I set it to a variable, I can change it once everywhere by changing the variable, and not have to re-write the query.

  • How to get an inner div to fill the entire wrapper div?

    - by ripper234
    I have the following html code: <div class="outer ui-draggable" style="position: relative;"> <div class="inner">Foo bar</div> </div> With this CSS: .outer { background-color: #F7F085; margin: 5px; height: 100px; width: 150px; text-align:center; vertical-align:text-bottom; } .outer .inner { display:inline; vertical-align:middle; height: 100px; width: 150px; } I would like the inner div to fill the outer div completely - the text block should be an entire 100X150 box. The problem is that this code doesn't produce the desired effect. The outer div is indeed the correct size, but the inner div seems to only fill a small area at the top of the outer div. I also tried using height:inherit and width:inherit instead of specifying a size.

  • Write a JavaScript that accepts a number from the user using the “prompt” function

    - by A sw A
    Write a JavaScript that accepts a number from the user using the “prompt” function. Then it draws a table in the HTML document that has the user specified number of rows and columns. In each table data, it displays the result of the math operation (row raised to the power of column). For example, if the user enters the number 3, the JavaScript should draw the following table: 1 1 1 2 4 8 3 9 27

  • load different images for each item on the listbox

    - by user161179
    Javascript: function changeMap() { imagesource = "http://maps.google.com/maps/api/staticmap?size=500x500&maptype=hybrid&zoom=16&sensor=false&markers=color:blue|label:K|28.541250,77.204100" ; mapimage.src = imagesource ; } Html code : <select name="choose_colony" id="choose_colony" size="8" onchange="changeMap()" style="float: left;"> <option value="1" >Big apartments</option> . . <option value="999">plaza</option> </select> <img name="mapimage" src="" alt="Select your Colony" style="float: right;"> In this whenever a selection on the listbox is made changeMap is called and an image is loaded. What I want is for a different image to be loaded everytime depending upon the option selected . there will be over 2000 entries in the listbox. Considering this what is the best way of going about this ? I can figure out the if/then part , but my main question is whether its ok to put all the 2000 long image addresses in the html file itself ? I hope I was clear ..

  • How can I add a column to this union result?

    - by MrXexxed
    I have this query (which I removed some keys from for brevity's sake): SELECT id as in_id, out_id, recipient, sender, read_flag FROM received WHERE recipient=1 UNION ALL SELECT in_id, id AS out_id, recipient, sender, read_flag FROM sent WHERE sender=1 Which combines the results from two tables showing messages sent and received by a given user. What I'd like to do is add a column/flag to the result to distinguish which table the row belongs to so when I display them I can show a relevant icon for sent or received messages. How would I add this?

  • JPA entity relations are not populated after .persist()

    - by Tomik
    Hello, this is a sample of my two entities: @Entity public class Post implements Serializable { @OneToMany(mappedBy = "post", fetch = javax.persistence.FetchType.EAGER) @OrderBy("revision DESC") public List<PostRevision> revisions; @Entity(name="post_revision") public class PostRevision implements Serializable { @ManyToOne public Post post; private Integer revision; @PrePersist private void prePersist() { List<PostRevision> list = post.revisions; if(list.size() >= 1) revision = list.get(list.size() - 1).revision + 1; else revision = 1; } So, there's a "post" and it can have several revisions. During persisting of the revision, entity takes a look at the list of the existing revisions and finds the next revision number. Problem is that Post.revisions is NULL but I think it should be automatically populated. I guess there's some kind of problem in my source code but I don't know where. Here's my "persistence" code: Post post = new Post(); PostRevision revision = new PostRevision(); revision.post = post; em.persist(post); em.persist(revision); em.flush(); I think that after persisting "post", it becomes "managed" and all the relations should be populated from now on. Thanks for help! (Note: public attributes are just for demonstration)

  • Allow users to pull temporary data then delete table data (headers remain)?

    - by JM4
    I don't know the best way to title this question but am trying to accomplish the following goal: When a client logs into their profile, they are presented with a link to download data from an existing database in CSV format. The process works, however, I would like for this data to be 'fresh' each time they click the link so my plan was - once a user has clicked the link and downloaded the CSV file, the database table would 'erase' all of its data and start fresh (be empty) until the next set of data populated it. My EXISTING CSV creation code: <?php $host = 'localhost'; $user = 'username'; $pass = 'password'; $db = 'database'; $table = 'tablename'; $file = 'export'; $link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error()); mysql_select_db($db) or die("Can not connect."); $result = mysql_query("SHOW COLUMNS FROM ".$table.""); $i = 0; if (mysql_num_rows($result) > 0) { while ($row = mysql_fetch_assoc($result)) { $csv_output .= $row['Field'].", "; $i++; } } $csv_output .= "\n"; $values = mysql_query("SELECT * FROM ".$table.""); while ($rowr = mysql_fetch_row($values)) { for ($j=0;$j<$i;$j++) { $csv_output .= '"'.$rowr[$j].'",'; } $csv_output .= "\n"; } $filename = $file."_".date("Y-m-d",time()); header("Content-type: application/vnd.ms-excel"); header("Content-disposition: csv" . date("Y-m-d") . ".csv"); header( "Content-disposition: filename=".$filename.".csv"); print $csv_output; exit; ?> any ideas?

  • Remove duplicates in a linked list before adding - C

    - by DesperateCoders
    Hi, My question is about removing duplicates from a linked list. But i want to do it before adding to linked list. struct myStr{int number; mystr *next;} void append(mystr **q,int item) { myStr *temp; temp = *q; myStr *newone; if(*q==NULL)// There should be control of previous elements. Call of keysearch function. { temp = (myStr *)malloc(sizeof(myStr)); temp->number =size; temp->next=NULL; *q=temp; } else //And also here { temp = *q; while(temp->next !=NULL) { temp=temp->next; } newone = (myStr *)malloc(sizeof(myStr)); newone->count = size; newone->next=NULL; temp->next=newone; } } int keysearch (myStr *p) { struct myStr *temp = p; int found = 0; int key= p->number; while (temp->number != NULL) { if(temp->number == key) { found = 1; } temp = temp->next; } return found; } My problem is in keySearch. I don't know what is wrong? Or is there another way for doing this.
