  • "Parsing" I think is the word.

    - by Anonymous the Great
    I'm working on a little parsing thing to color objects. For an example, you could type red:Hi!: and "Hi!" would be red. This is my not working code: <script type="text/javascript"> function post() { var preview = document.getElementById("preview"); var submit = document.getElementById("post"); var text = submit.value; <?php str_replace("red:*:",'<i class="red">*</i>',text); ?> preview.value = text; } </script>

  • Constructing a tree using Python

    - by stealthspy
    I am trying to implement a unranked boolean retrieval. For this, I need to construct a tree and perform a DFS to retrieve documents. I have the leaf nodes but I am having difficulty to construct the tree. Eg: query = OR ( AND (maria sharapova) tennis) Result: OR | | AND tennis | | maria sharapova I traverse the tree using DFS and calculate the boolean equivalent of certain document ids to identify the required document from the corpus. Can someone help me with the design of this using python? I have parsed the query and retrieved the leaf nodes for now.

  • Using jQuery in WordPress plugin admin page?

    - by Volmar
    I have a strange problem that probably have a really simple explanation that i've just havn't found. I'm making a WordPress plugin and i want to use jQuery in my settings-page for the plugin. My JS functions look like this: jQuery(document).ready(function() { alert('load test'); //ADMIN FUNCTION $('#mrc_imp_img').click(function(){ alert("test"); }); //FRONT END FUNCTION $("ul.mrc li").hover(function() { $(this).find('p').fadeIn(); } , function() { $(this).find('p').fadeOut(); }); }); The "load test"-alert is being loaded when the document is ready so jquery is properly loaded. The front end function is being used on pages and that's working fine to. the problem is the admin function, it's not working at all. is there a speial way i have to write a .click()-function to get it to work on my settings-page for the wordpress plugin?

  • How can i return List of directories instead of url's?

    - by user1741587
    I have this function : private List<string> getLinks(HtmlAgilityPack.HtmlDocument document) { List<string> mainLinks = new List<string>(); var linkNodes = document.DocumentNode.SelectNodes("//a[@href]"); if (linkNodes != null) { foreach (HtmlNode link in linkNodes) { var href = link.Attributes["href"].Value; if (href.StartsWith("http://") == true || href.StartsWith("https://") == true || href.StartsWith("www") == true) // filter for http { mainLinks.Add(href); } } } return mainLinks; } Its getting one url and return list of url's. Instead i want that the function will get a directory for example c:\ And it will return me a List of all directories in c:\ Not subsirectories just the directories in c:\ in my case it should be a List with a 14 directories. Meaning in each index in the List a directory. How can i do it ? Tried with Directory and DirectoryInfo but i just got messed up.

  • Preoblem with Precision floating point operation in C

    - by Microkernel
    Hi Guys, For one of my course project I started implementing "Naive Bayesian classifier" in C. My project is to implement a document classifier application (especially Spam) using huge training data. Now I have problem implementing the algorithm because of the limitations in the C's datatype. ( Algorithm I am using is given here, http://en.wikipedia.org/wiki/Bayesian_spam_filtering ) PROBLEM STATEMENT: The algorithm involves taking each word in a document and calculating probability of it being spam word. If p1, p2 p3 .... pn are probabilities of word-1, 2, 3 ... n. The probability of doc being spam or not is calculated using Here, probability value can be very easily around 0.01. So even if I use datatype "double" my calculation will go for a toss. To confirm this I wrote a sample code given below. #define PROBABILITY_OF_UNLIKELY_SPAM_WORD (0.01) #define PROBABILITY_OF_MOSTLY_SPAM_WORD (0.99) int main() { int index; long double numerator = 1.0; long double denom1 = 1.0, denom2 = 1.0; long double doc_spam_prob; /* Simulating FEW unlikely spam words */ for(index = 0; index < 162; index++) { numerator = numerator*(long double)PROBABILITY_OF_UNLIKELY_SPAM_WORD; denom2 = denom2*(long double)PROBABILITY_OF_UNLIKELY_SPAM_WORD; denom1 = denom1*(long double)(1 - PROBABILITY_OF_UNLIKELY_SPAM_WORD); } /* Simulating lot of mostly definite spam words */ for (index = 0; index < 1000; index++) { numerator = numerator*(long double)PROBABILITY_OF_MOSTLY_SPAM_WORD; denom2 = denom2*(long double)PROBABILITY_OF_MOSTLY_SPAM_WORD; denom1 = denom1*(long double)(1- PROBABILITY_OF_MOSTLY_SPAM_WORD); } doc_spam_prob= (numerator/(denom1+denom2)); return 0; } I tried Float, double and even long double datatypes but still same problem. Hence, say in a 100K words document I am analyzing, if just 162 words are having 1% spam probability and remaining 99838 are conspicuously spam words, then still my app will say it as Not Spam doc because of Precision error (as numerator easily goes to ZERO)!!!. This is the first time I am hitting such issue. So how exactly should this problem be tackled?

  • jquery custom drag and drop

    - by samlochner
    I am trying to create functionality similar to drag and drop. I need to create my own as there will be some significant differences to the drag and drop in the jquery UI. I would like to have mousemove being called repeatedly at all times, and mousedown called every time the mouse is pressed. So I have the following code: $(document).bind('mousemove',function(e){ $("#coords").text("e.pageX: " + e.pageX + ", e.pageY: " + e.pageY); }); $(document).bind('mousedown',function(e){ }); ('coords' is the id of a div) As I move the mouse, coordinates are reported correctly in 'coords'. If I depress a mouse button and then move the mouse, coordinates are still reported correctly. But if I depress a mouse button on an image and then move the mouse, coordinates are reported correctly for a few sets, and then they seize up! Why is this happening and how can I fix it? Thanks, Sam

  • Dynamic added elements double effect after page transition

    - by Emil Moe
    I have added dynamic from jQuery in my code, but when I go back one page and return to the page where the 's are added and you press them, they somehow click twice now. I have tried with an alert('something'); when I click: $(document).on('click', '#products a', function() { alert('something'); } And it's shown twice when you return to the page. I have tried $('#products a').remove(); When you click the 'Back' button, because I thought all elements where added twice, but that made no difference. I don't have anything around these lines, maybe I need $(document).ready(); or something with pageinit?

  • adding results of XML request to a page

    - by user2925833
    I am trying to get a feel for adding content to a page with XMLHTTPRequest. I would like to add the results to existing page content say in a second column, but I am not having any luck. I would appreciate a shove in the right direction. Thanks for any help. <!DOCTYPE html> <html> <head> <style> #button{ float: left; } #team{ float: left; } </style> <title>XMLHTTPRequest</title> <script src="jquery-1.10.2.js"></script> <script> $(document).ready(function(){ xhr = new XMLHttpRequest(); xhr.onreadystatechange = function(){ if (xhr.readyState == 4 && xhr.status == 200) { xmlDoc = xhr.responseXML; var team = xmlDoc.getElementsByTagName("teammember"); var html = ""; for (i = 0; i < team.length; i++){ html += xmlDoc.getElementsByTagName("name")[i].childNodes[0].nodeValue + "<br>" + xmlDoc.getElementsByTagName("title")[i].childNodes[0].nodeValue + "<br>" + xmlDoc.getElementsByTagName("bio")[i].childNodes[0].nodeValue + "<br><br>"; } //this is the code I would like help with var team = document.getElementById("team"); team.appendChild(document.createTextNode("html")); } } xhr.open("GET", "team.xml", true); }); </script> </head> <body> <div id="button"> <button onclick="xhr.send()">Click Me!</button> </div> <div id="team"> </div> </body> </html>

  • Javascript : random number between variables issue

    - by Mayhem
    I've seen the other examples on this site but I just can't get it to work. I'm trying to generate a random number between 2 user input variables on a form. The numbers will always be positive numbers. min = document.getElementById('min').value; max = document.getElementById('max').value; waitTimer = Math.floor(Math.random() * (max - min + 1)) + min; When min = 5 / max = 10, waitTimer is sometimes returning results like 2, 4 and 28 and so on. What am I doing wrong?

  • Can't access variables from dynamically loaded javascript

    - by Menno
    I'm using a fairly simple system to load javascript dynamically: include = function (url) { var e = document.createElement("script"); e.src = url; e.type="text/javascript"; document.getElementsByTagName("head")[0].appendChild(e); }; Let's say I have a file test.js which has the following contents: var foo = 4; Now, in my original script, I want to use include(test.js); console.log(foo); However, I get a 'foo has not been defined' error on this. I'm guessing it has to do with the dynamic script being included as the last child of the <head> tag. How can I get this to work?

  • how to inject javascript code in url to insert iframe in existing page

    - by dotnetcoder
    I am able to get the following JS to create IFRAME and add it to the page. The issue is if I create JS method on the page and ivoke it on a button click it works. But when I try to inject the same JS into the page url via setting the location.href it does not work the right way , rather it replaces the existing page with a new iframe. Here is my code: location.href = "javascript:ifrm = document.createElement('IFRAME');ifrm.style.width = 60+'px';ifrm.style.height = 40+'px';document.body.appendChild(ifrm);";

  • Wrapping pre-made elements using GWT?

    - by user246114
    Hi, I've been working with GWT for awhile, I can't find a way to integrate it with a preexisting website which is a real downer. My page content is already generated for me using jsp, like: <div id='A'></div> <div id='B'></div> etc. there is no way for me to do something like this though: public void onModuleLoad() { SimplePanel spA = new SimplePanel( Document.getElementById("A")); spA.add(new Label("hello")); SimplePanel spB = new SimplePanel( Document.getElementById("B")); spB.setWidth("200px"); etc .. } seems like there's no way to just wrap a pre-existing element. Is this true, or am I missing how to do this? I need be able to wrap a bunch of elements like this, to manipulate them later on. I see TextBox, Button, a few other classes have wrap() methods, however nothing like that exists for elements, Thanks

  • resource embedding in asp.net

    - by Mike
    I have a project which needs to generate PDF documents. I am using iTextSharp. I have a pdf which needs to be read and then appended to. To read the pdf document, I'm using PdfReader(), which accepts many forms, but I can't figure out how to reference a pdf in my webapplication to PdfReader. My host does not allow Binary Serialization (apparently that's bad), so I don't think I can load from an embedded resource. I've tried just using PdfReader("report.pdf"), but it keeps throwing an exception telling me that the file isn't found. I've tried putting the file in the bin directory, root directory, in the same directory as the class, but this still doesn't work. It works if I use a fully qualified path to the pdf document, but I can't use that when I upload it to my hosting provider. Does anyone have any suggestions on how I should do this? Thanks

  • opening iWorks documents in iPad UIWebView

    - by user369156
    Hello, I'm writing an iPad application that has a UIWebView which I open word and excel documents in, but I want the user to be able to import those documents into the iWorks applications, Pages and Numbers, just like how you can do it in Safari if you open a document. If you open a document in Safari on the iPad, there'll be a button on the top bar that says "Open in..." and you can choose applications to open in. You get the top bar to appear by tapping on middle of the page. So is there an option you can set to allow UIWebView to show up the bar and automatically detect the content type and populate the list with applications you can import in? Or do I have to build this myself? And if I have to build my own, how do I open URLs to import documents into Pages and Numbers etc? Thanks, -David

  • Appropriate use of DL and DD?

    - by Ian
    I had some site templates designed for me recently. I got the final HTML code, which validates, but the structure of the document is laid out using DL-DD pairs: <dl> <dd class="some-class"> Some text. </dd> </dl> I'm not especially familiar with those tags as I've never used them much, but they don't seem intended for document structure. Am I right? Why would a designer do this?

  • simulate to change the background color when click the link

    - by tom
    I have the following HTML and the java script below to simulate the background color change when the link block is clicked, but it doesn't seem to work. Any reason why? If I have only the onmousedown event handled, the background color will be changed to blue for sure. But if both onmousedown and onmouseup are handled, nothing would change visually. note... function changeColorOnMouseDown() { document.getElementById('note').style.background='blue'; } function changeColorOnMouseUp() { document.getElementById('note').style.background='#d8dde7'; }

  • How can I keep doxygen from documenting #defines in a C file?

    - by Chris Nelson
    I have #define values in headers that I certainly want Doxygen to document but I have others in C files that I treat as static constants and I don't want Doxygen to document them. Something as simple and stupid as #define NUMBER_OF(a) (sizeof((a))/sizeof((a)[0])) #define MSTR(e) #e How can I keep Doxygen from putting those #defines in the documentation it creates? I've tried marking it with @internal but that didn't seem to help. A somewhat-related question on Doxygen and #define, how can I get: #define SOME_CONSTANT 1234 /**< An explanation */ to put "SOME_CONSTANT" and "An explanation" but not "1234" in the output?

  • Which event to catch for application shut down?

    - by xueru
    I am using jQueryMobile and phoneGap for a cross-device mobile application. I use html 5 local storage to persist records that worked on by user. I don't know which phoneGap event to catch just before application shut-down so I can make sure data is saved before shutdown completes. Base on suggestion from naughtur, I tried both unload and beforeunload events, neither of them got fired during app shutdown. Following is my code snip: function persistTasks(){ alert ("is unloading the app"); offlineTasklist.set("tasks", tasklist); } function init() { document.addEventListener("unload", persistTasks, false); login(); } $(document).ready(init);

  • contenteditable element prevents hyperlink default behavior

    - by user352208
    I've got the following problem. In IE if a contenteditable element is nested inside a hyperlink, clicking on the element prevents the hyperlink default behavior, i.e. navigation to another document. In FF it works fine. How can I solve the problem? Just removing the contentEditable attribute is not a solution since I want this behavior (navigation to another document) only when user clicks the content-editable element with pressed Ctrl key. Thanks.

  • index seems to be out of sync for jquery .keydown and .click methods

    - by Growler
    I'd like to navigate images using both keyboard and mouse (clicking left and right arrow images). I'm using Jquery to do this, but the shared imgIndex seems to be off from the .keydown function and the .click function... Whenever .keydown function -- or ++ the imgIndex, isn't that changed index also used in the click function? So shouldn't they always be on the same index? keydown function: <script type="text/javascript"> var imgArray = [<?php echo implode(',', getImages($site)) ?>]; $(document).ready(function() { var img = document.getElementById("showimg"); img.src = imgArray[<?php echo $imgid ?>]; var imgIndex = <?php echo $imgid ?>; alert(imgIndex); $(document).keydown(function (e) { var key = e.which; var rightarrow = 39; var leftarrow = 37; var random = 82; if (key == rightarrow) { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; } if (key == leftarrow) { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; } }); click function: Connected to left and right clickable images $("#next").click(function() { imgIndex++; if (imgIndex > imgArray.length-1) { imgIndex = 0; } img.src = imgArray[imgIndex]; }); $("#prev").click(function() { if (imgIndex == 0) { imgIndex = imgArray.length; } img.src = imgArray[--imgIndex]; }); }); Just so you have some visibility into the getImages php function: <?php function getImages($siteParam) { include 'dbconnect.php'; if ($siteParam == 'artwork') { $table = "artwork"; } else { $table = "comics"; } $catResult = $mysqli->query("SELECT id, title, path, thumb, views, catidFK FROM $table"); $img = array(); while($row = $catResult->fetch_assoc()) { $img[] = "'" . $row['path'] . "'"; } return $img; } ?> Much appreciated! Snapshot of where the script is on "view image.php"
