  • Search row with highest number of cells in a row with colspan

    - by user593029
    What is the efficient way to search highest number of cells in big table with numerous colspan (merge cells ** colspan should be ignored so in below example highest number of cells is 4 in first row). Is it js/jquery with reg expression or just the loop with bubble sorting. I got one link as below explainig use of regex is it ideal way ... can someone suggest pseudo code for this. High cpu consumption due to a jquery regex patch <table width="156" height="84" border="0" > <tbody> <tr style="height:10px"> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> </tr> <tr style="height:10px"> <td width="10" style="width:10px; height:10px" colspan="2"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> </tr> <tr style="height:10px"> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px" colspan="2"/> </tr> <tr style="height:10px"> <td width="10" style="width:10px; height:10px" colspan="2"/> <td width="10" style="width:10px; height:10px"/> <td width="10" style="width:10px; height:10px"/> </tr> </tbody> </table>

  • asp.net checkbox in gridview - checked property is missing

    - by Peter PitLock
    In this asp.net gridview control, the checked property is always missing. I need to access the checked property via jquery Gridview source: <Columns> <asp:TemplateField> <ItemTemplate> <asp:CheckBox ID="chkSelected" runat="server" class="chkSummarySelection" /> </ItemTemplate> </asp:TemplateField> </Columns> Renders as : <input type="checkbox" name="ctl00$ContentPlaceHolder1$gv$ctl02$SelectedCheckBox" id="ctl00_ContentPlaceHolder1_gv_ctl02_SelectedCheckBox"> There is no checked property to access. I have tried $(".chkSummarySelection").click(function () { var chk; chk = $(this).prop("checked"); chk = $(this).attr("checked"); chk = $(this).is(":checked"); chk = $(this).attr("value"); chk = $(this).val(); chk = jQuery(this).is(':checked'); }); but nothing is working

  • Can you explain this odd behavior with dragging items into nested sortables?

    - by RDL
    I have the following setup: A sortable list where one of the <li> has a table with lists in each cell. All of the lists are sortable with each other. Draggable items that can be added to any of the sortables Issue: When adding a draggable item ('drag 1', 'drag 2', 'drag 3') to one of the lists in the horizontal lists (table of lists) it duplicates the draggable when dropped. Sometimes it will create both copies in the same list or one in the item list and one in the column list. Here is a demo: http://jsfiddle.net/MQTgA/ Question: How do I prevent the second item being created when dropping the draggable?

  • Denying main links with .htaccess or anything else

    - by user1640660
    I'm using an encrypted php program with smarty template. I wanted to open links such as index.php?page=login to open with login.php, so I used Rewrite mode in .htaccesss, for example RewriteRule ^/*login.php$ /index.php?page=login [L] in a few pages there should be a query for errors such as RewriteRule ^/*support.php?(.+)$ /index.php?page=support&%{QUERY_STRING} [L] It works but I need to deny the main URLs so when users enters index.php?a=login manually nothing (or the main page) would show up and he should open the link only with /login.php. Is there a way to do this? A little help please...

  • jQuery DOM append losing markup

    - by Raj
    This is related to an earlier question. I try to append HTML DOM returned in an AJAX response to an existing DIV. I see all the text, but it seems all markup such as bold, italic, etc is lost. My AJAX (XML) data is like so: <event source="foo"> <contents> <h1>This is an event</h1> This is the body of the event </contents> </event> My jQuery code does this: $("#eventDiv").append( jData.find("contents").contents().clone() ); Attempting to do .html() on the cloned contents throws an exception: TypeError: Cannot call method 'replace' of undefined. I am a little surprised that it is so excruciatingly hard to do this with jQuery. Am I doing something too far off the track?

  • How do I handle the messages for a simple web-based live chat, on the server side?

    - by Carson Myers
    I'm building a simple live chat into a web application running on Django, but one thing I'm confused about is how I should store the messages between users. The chat will support multiple users, and a chat "session" is composed of users connected to one user that is the "host." The application is a sort of online document collaboration thing, so user X has a document, and users Y and Z would connect to user X to talk about the document, and that would be one chat session. If user Y disconnected for five minutes, and then signed back in and reconnected to user X, he should not get any of the messages shared between users X and Z while he was away. if users X, Y, and Z can have a chat session about user X's document, then users X and Y can connect to a simultaneous, but separate discussion about user Z's document. How should I handle this? Should I keep each message in the database? Each message would have an owner user and a target user (the host), and a separate table would be used to connect users with messages (which messages are visible to what users). Or should I store each session as an HTML file on the server, which messages get appended to? The problem is, I can't just send messages directly between clients. They have to be sent to the server in a POST request, and then each client has to periodically check for the messages in a GET request. Except I can't just have each message cleared after a client fetches it, because there could be multiple clients. How should I set this up? Any suggestions?

  • jQuery resizable() dynamic maxWidth option

    - by Vitaliy Isikov
    I have 3 columns that are resizable. When one is made wider, the one to it's left is made smaller. Essentially there are only 2 handles. Left col and Mid col. So when Mid col is made thinner, Right col expands accordingly. All three of them are contained with a 900px parent div, so the sum of all three is always 900. They have max and min widths set statically. My issue is that if you take the left handle and move it all the way to the right you're still able to use the right handle and expand the mid col past the edge of the parent div. I thought of a way to solve that issue by writing up a function that checks the widths of the columns and then subtracts left and right columns from the parent div width, I called it mWid. This leaves me with the number I want to set as the maxWidth for Mid col. Now the issue is that mWid is not gettings updated for here "maxWidth: mWid" Here is what the function for the right handle looks like: $(function() { $("#midResizable").resizable({ handles: 'e', containment: '#container', maxWidth: mWid, // gets set once, but doesn't update! WHY? minWidth: 195, resize: function(event, ui) { contWidth = $('#container').width() newWidth = $(this).width() leftWidth = $('#leftResizable').width() rightWidth = $('#rightResizable').width() $("#rightResizable").css("width", (contWidth-15)-(newWidth)-(leftWidth)+"px"); checkWid() } }); }); function checkWid() { rightWidth = $('#rightResizable').width() leftWidth = $('#leftResizable').width() contWidth = $('#container').width() mWid = (contWidth-15)-(rightWidth)-(leftWidth) }

  • Google Chrome Extension : Port: Could not establish connection. Receiving end does not exist

    - by tcornelis
    I have been looking for an answer for almost a week now, but having read all the stackoverflow items i can't seem to find a solution that is working for me. The error that i'm having is : Port: Could not establish connection. Receiving end does not exist. lastError:30 set lastError:30 dispatchOnDisconnect messaging:277 folder layout : img developer_icon.png js sidebar.js main.js jquery-2.0.3.js manifest.json my the manifest.json file looks something like this (it is version 2) :` "browser_action": { "default_icon": "./img/developer_icon.png" }, "content_scripts": [ { "matches": ["*://*/*"], "js": ["./js/sidebar.js"], "run_at": "document_end" } ], "background" : { "scripts" : ["./js/main.js","./js/jquery-2.0.3.js"] }, I want to handle the user clicking the extension icon so i could inject a sidebar in the existing website (because the extension i would like to develop requires that amount of space). So in main.js : chrome.browserAction.onClicked.addListener(function(tab) { chrome.tabs.getSelected(null, function(tab){ chrome.tabs.sendMessage( //Selected tab id tab.id, //Params inside a object data {callFunction: "toggleSidebar"}, //Optional callback function function(response) { console.log(response); } ); }); }); and in sidebar.js : chrome.runtime.onMessage.addListener(function(req,sender,sendResponse){ console.log("sidebar handling request"); toggleSidebar(); }); but i'm never able to see the console.log in my console because of the error. Does someone know what i did wrong? Thanks in advance!

  • Sliding panel in the middle of the page. Z-index given not working

    - by Nehal Rupani
    Hi all, I am implementing sliding panel element but problem is when i slide out other div element is floating down. I guess and tried to give z-index to element which i am sliding but it doesn't seems to work. Let me put code for both div. <div class="vrcontrol"> <div class="slide-out-div"> <a class="handle" href="http://link-for-non-js-users.html">Content</a> <h3>Contact me</h3> <p>Thanks for checking out my jQuery plugin, I hope you find this useful. </p> <p>This can be a form to submit feedback, or contact info</p> </div> This is div which i am sliding in and out and beneath is code of effective div. <div class="askform"> <p class="titletext">Ask an Expert Trade Forum</p> <p class="detailtext">WD-40’s leading source for DIY tips and tricks.</p> <span> <form id="askform" name="askform" action="" method="post"> <span class="left"><input name="input" type="text" class="askinputbox"/></span><span class="marginleft"><input type="image" src="images/search_icon.gif" /></span> </form> </span> <div class="followus"> <span class="followtext">Follow us on</span><span class="right"><img src="images/bookmark.jpg" width="121" height="45" alt="Bookmark" /></span> </div> </div> Sliding div is in left portion of the page and effective div is in right portion of the page. I guess something with z-index, positioning element and overflow properties will do something.

  • HTML 5 drag-drop into wysiwyg editor in Firefox

    - by einarq
    I have a wysiwyg editor using the HTML 5 drag-drop api to allow the user to place widgets within the page they are editing. When the OnDrop event fires, I prevent the default event, and insert some html within the editor that represents the widget they inserted. I use execCommand("inserthtml", false, html) for this in Firefox. This works fine in IE, but in Firefox the html is not placed in the location where it was dropped. It always gets placed in the location where the previous selection was, which leads me to believe that cancelling the OnDrop event to override the default drop also cancels the selection change. Any ideas on how to solve this? Thanks!

  • A quick question on data returned by jquery.ajax() call (EDITED)

    - by recipriversexclusion
    EDIT: The original problem was due a stupid syntax mistake somewhere else, whicj I fixed. I have a new problem though, as described below I have the following jquery.ajax call: $.ajax({ type: 'GET', url: servicesUrl + "/" + ID + "/tasks", dataType: "xml", success : createTaskListTable }); The createTaskListTable function is defined as function createTaskListTable(taskListXml) { $(taskListXml).find("Task").each(function(){ alert("Found task") }); // each task } Problem is: this doesn't work, I get an error saying taskListXml is not defined. JQuery documentation states that the success functions gets passed three arguments, the first of which is the data. How can I pass the data returned by .ajax() to my function with a variable name of my own choosing. My problem now is that I'm getting the XML from a previous ajax call! How is this even possible? That previous function is defined as function convertServiceXmlDataToTable(xml), so they don't use the same variable name. Utterly confused. Is this some caching issue? If so, how can I clear the browser cache to get rid of the earlier XML? Thanks!

  • jQuery plugin: Validation can't be customized without setting all fields to 'required'?

    - by rasx
    I've spent the day looking at jQuery plugin: Validation by Jörn Zaefferer. I notice that it works fine as long as you call the validate() method without options. In my little squalid world, as soon as I add options, like errorPlacement, I notice that validation ignores form fields that are not marked required. I also notice that many, many demos mark all fields required---or do not pass options. Am I writing about anything familiar here? Or should I astral project to a parallel universe?

  • How can I paste an image from the clipboard into a web form?

    I found this question, but the question is about how to get an image from the clip board into a wyziwyg editor! My question is "How can I paste an image from the clipboard into a field (what field is not that big issue as long as it works)", and then sent to the server. Jira has this functionality, so it should be possible! Any ideas on how to do this? Just to explain the complete workflow; I would like to have a plave to multi upload images, where the paste from clipboard also is an option. The upload will be some ajax of some sort, bt is not important in this context! Thanks

  • How can I highlight the line of text that is closest to the mouse?

    - by Aaron Digulla
    I have a long text and I'd like to offer the user a reading help: The current line should be highlighted. To make it easier, I'll just use the Y coordinate of the mouse (this way, the mouse pointer isn't going to get in the way). I have a big DIV with the id content which fills the whole width and a small DIV with the class content for the text (see here for an example). I'm using jQuery 1.4. How can I highlight the line of text that is closest to the current mouse position?
