  • ASP.NET server side show JS Alert box, doesn't work when using partial post back.

    - by jamone
    I have put the following method in my master page. It works when I call it on a full post back, but when I call it from a updatePanel's asyncPostBack no alert is shown. public void ShowAlertMessage(String message) { string alertScript = String.Format("alert('{0}');", message); Page.ClientScript.RegisterStartupScript(this.GetType(), "Key", alertScript, true); } What do I need to do so it works on partial post backs?

  • iframe.document.body.scrollHeight is double the correct value

    - by Dean J
    <iframe name="asdf" id="asdf" onload="change_height(this)" src="asdf.jsp" width="250" scrolling="no" frameborder="0"></iframe> function change_height(iframe) { if (document.all) { // IE. ieheight = iframe.document.body.scrollHeight; iframe.style.height = ieheight; } else { // Firefox. ffheight= iframe.contentDocument.body.offsetHeight; iframe.style.height = ffheight+ 'px'; } } ieheight is twice the actual height when this runs in IE7; haven't tested on IE6. It's the same value if I use scrollHeight or offsetHeight. It's the correct height in Firefox. Before I patch this by just dividing the IE value /2, what's the right way to do this?

  • Retrieve click() handler in jQuery for later use

    - by Xiong Chiamiov
    I'm using the jQuery tablesorter plugin to sort a table, which assigns .click() handlers to the <th>s in the table. Since my table has alternating colors for each column, I've built a simple fix_table_colors(identifier) function that does as it should when I call it manually using Firebug. I would like, however, to have that automatically called after a sort. To do this, I decided to retrieve the .click() handler from the <th>s, and assign a new handler that simply calls the previous handler, followed by fix_table_colors(). (This SO question is similar, but uses standard onClick() attributes, which won't work here.) From the accepted answer to this question, I have created the following code: $(document).ready(function() { $("table.torrents").tablesorter({ debug: true, headers: { 1: { sorter: 'name' }, 2: { sorter: 'peers' }, 3: { sorter: 'filesize' }, 4: { sorter: 'filesize' }, 5: { sorter: 'filesize' }, 6: { sorter: 'ratio' } } }); $('table.torrents thead th').each(function() { var th = $(this); var clickHandler = th.data('events').click[0]; th.click(function() { clickHandler(); fix_table_colors('table.torrents'); }); }); }); While this is conceptually correct, clickHandler doesn't appear to actually be a function, and so I cannot call it. With a bit more digging in Firebug, I found that click[3] appears to hold the function I'm looking for (and click[10] my new one). I get an 'e is undefined' error on line 2 of tablesorter.min.js when using that, though. Am I even going down the right path? I have a feeling that with what I've found so far, I can make this work, but it's going to be much uglier than I would expect it needs to be.

  • Creating a notification system using a firefox extension

    - by user303052
    I am creating a firefox extension that should give a notification when the user hits specific sites. I do not want the same kind of notification that firefox gives for pop-ups. I don't want the user to have to go through the hassle of clicking the X in order to close the notification. Instead, I would like it to look like what happens when a normal firefox download is completed - a notification comes up, and automatically goes after a few seconds. On a mac, it looks like a growl notification, and I love the way it looks. Is there an easy way to implement this feature? Thanks

  • Send post request from client to node.js

    - by Husar
    In order to learn node.js I have built a very simple guestbook app. There is basically just a comment form and a list of previous comments. Currently the app is client side only and the items are stored within local storage. What I want to do is send the items to node where I will save them using Mongo DB. The problem is I have not yet found a way to establish a connection to send data back and forth the client and node.js using POST requests. What I do now is add listeners to the request and wait for data I send: request.addListener('data', function(chunk) { console.log("Received POST data chunk '"+ chunk + "'."); }); On the client side I send the data using a simple AJAX request: $.ajax({ url: '/', type: 'post', dataType: 'json', data: 'test' }) This does not work at all in them moment. It could be that I don't know what url to place in the AJAX request 'url' parameter. Or the whole thing might just be the build using the wrong approach. I have also tried implementing the method described here, but also with no success. It would really help if anyone can share some tips on how to make this work (sending POST request from the client side to node and back) or share any good tutorials. thanks.

  • JQuery: Toggle submit button according to if terms are agreed with or not

    - by Svish
    I have a checkbox with id terms and a submit button in my form with class registration. I would like the submit button to be disabled initially, and then to be toggled on and off whenever the user toggle on and off the terms checkbox. I would also like to have a confirmation dialog pop up when the submit button is clicked and that if it is confirmed the submit button will be disabled again (to prevent duplicate clicking). I have gotten the last part and the first part working (I think), but I can't figure out how to get the toggling working. This is what I have so far: $(document).ready(function() { // Disable submit button initially $('form.registration input[type=submit]').attr('disabled', 'disabled'); // Toggle submit button whenever the terms are accepted or rejected $('#terms').change(function() { if($('#terms:checked').val() !== null) $('input[type=submit]', this).attr('disabled', ''); else $('input[type=submit]', this).attr('disabled', 'disabled'); }); // Ask for confirmation on submit and disable submit button if ok $('form.registration').submit(function() { if(confirm('Have you looked over your registration? Is everything correct?')) { $('input[type=submit]', this).attr('disabled', 'disabled'); return true; } return false; }); }); Could someone help me make this work? I'm a total JQuery newb at the moment, so any simplifications and fixes are welcome as well.

  • Destructuring assignment problem

    - by Eli Grey
    Why does for ([] in iterable); work fine but [void 0 for ([] in iterable)] throw a syntax error for invalid left-hand assignment? For example, I would expect the following code to work, but it doesn't (the assertion isn't even done due to the syntax error): let (i = 0, iterable = (i for (i in [1, 2, 3, 4]))) { for ([] in iterable) i++; console.assertNotGreater([void 0 for ([] in iterable)].length, i); }

  • twitter bootstrap typeahead (method 'toLowerCase' of undefined)

    - by mmoscosa
    I am trying to use twitter bootstrap to get the manufacturers from my DB. Because twitter bootstrap typeahead does not support ajax calls I am using this fork: https://gist.github.com/1866577 In that page there is this comment that mentions how to do exactly what I want to do. The problem is when I run my code I keep on getting: Uncaught TypeError: Cannot call method 'toLowerCase' of undefined I googled around and came tried changing my jquery file to both using the minified and non minified as well as the one hosted on google code and I kept getting the same error. My code currently is as follows: $('#manufacturer').typeahead({ source: function(typeahead, query){ $.ajax({ url: window.location.origin+"/bows/get_manufacturers.json", type: "POST", data: "", dataType: "JSON", async: false, success: function(results){ var manufacturers = new Array; $.map(results.data.manufacturers, function(data, item){ var group; group = { manufacturer_id: data.Manufacturer.id, manufacturer: data.Manufacturer.manufacturer }; manufacturers.push(group); }); typeahead.process(manufacturers); } }); }, property: 'name', items:11, onselect: function (obj) { } }); on the url field I added the window.location.origin to avoid any problems as already discussed on another question Also before I was using $.each() and then decided to use $.map() as recomended Tomislav Markovski in a similar question Anyone has any idea why I keep getting this problem?! Thank you

  • Dynamically creating a TreeViewin HTML with indent lines in ASP.NET

    - by Ben
    Hi, i'm quite new to HTML, and am trying to create a professional looking TreeView. I can not use the in built TreeView in ASP.NET as i need to point the target of the selection to another frame (I have tried, and this doesn't seem possible). My TreeView is built up as follows: Folder1 ChildOne ChildTwo ChildThree Folder2 ChildOne ChildTwo ChildThree I have the collapsing of the folders working, but would like to know how to format this TreeView so it has dotted lines down to the child nodes (as most TreeViews tend to have). How would i go about this? Cheers.

  • jQuery plug-in to remap numeric keypad

    - by Álvaro G. Vicario
    Is there a jQuery plug-in to remap the "dot" key in the numeric keypad? The purpose is to make it print a decimal separator, rather than a dot, in languages that use commas or other characters. I'd like to mimic the behaviour of some desktop applications like MS Excel. (It's okay to hard-code the output character.)

  • Not all parameters get sent in jquery ajax call

    - by rksprst
    I have a strange error where my jquery ajax request doesn't submit all the parameters. $.ajax({ url: "/ajax/doAssignTask", type: 'GET', contentType: "application/json", data: { "just_a_task": just_a_task, "fb_post_date": fb_post_date, "task_fb_postId": task_fb_postId, "sedia_task_guid": sedia_task_guid, "itemGuid": itemGuid, "itemType": itemType, "taskName": taskName, "assignedToUserGuid": assignedToUserGuid, "taskDescription": taskDescription }, success: function(data, status) { //success code }, error: function(xhr, desc, err) { //error code } }); But using firebug (and debugging) I can see that only these variables are posted: assignedToUserGuid itemGuid itemType just_a_task taskDescription taskName It's missing fb_post_date, task_fb_postId, and sedia_task_guid I have no idea what would cause it to post only some items and not others? Anyone know? Data is sent to asp.net controller that returns jsonresult (hence the contentType) Any help is appreciated. Thanks!

  • HTML 5 Canvas - Dynamically include multiple images in canvas

    - by Ron
    I need to include multiple images in a canvas. I want to load them dynamically via a for-loop. I tried a lot but in the best case only the last image is displayed. I check this tread but I still get only the last image. For explanation, here's my latest code(basically the one from the other post): for (var i = 0; i <= max; i++) { thisWidth = 250; thisHeight = 0; imgSrc = "photo_"+i+".jpg"; letterImg = new Image(); letterImg.onload = function() { context.drawImage(letterImg,thisWidth*i,thisHeight); } letterImg.src = imgSrc; } Any ideas?

    I am tryting to develop a chart in Highstock where each marker got an individual color. When i push my Data in an Array like this : series.data.push([ parseInt(Math.round(myDate.getTime())), parseInt(Math.round(myDate.getHours())) ]); The Data is shown correctly, but when i try to set the color within each data-object like this, it doesn't work to show points. series.data.push([ { x: parseInt(Math.round(myDate.getTime())), y: parseInt(Math.round(myDate.getHours())), marker:{fillColor: 'red'}} ]); What am i missing? Update: When i inspect it with firebug i can see that the series is set correctly within the chart object. so why does it now show up? :/

  • jEditable - how do I get the edited textfield variable?

    - by Forkrul Assail
    I have a table that I use jEditable with. Saving to the server works, but the callback for refreshing my table element (that I just edited and saved to the server) does not work. /* Apply the jEditable handlers to the table */ $('#example tbody td').editable( '<%= url_for :controller => 'impact_matrix', :action => 'post', :scenario => params[:id] %>', { "callback": function( sValue, y ) { ^ goes missing var aPos = oTable.fnGetPosition( this ); oTable.fnUpdate( sValue, aPos[0], aPos[1] ); }, "submitdata": function ( value, settings ) { temp = value return { "row_id": this.parentNode.getAttribute('id') }; }, sValue (that I point to in the code) - seems to be blank. I do get values for aPos[0] and aPos[1], but not sValue. Could someone please explain to me 'what triggers the callback function?' Or, if I could just see where to get the 'newly edited text' and then just run fnUpdate() on that, I'd be fine. Thanks in advance for your help.

  • Jquery AJAX and figuring out how NOT to nest callbacks for multiple reloads.

    - by David H
    I have a site with a few containers that need to load content dynamically via AJAX. Most of the links inside of the containers actually load new data in that same container. I.E: $("#navmenu_item1").click(function() { $("#navmenu").load(blah); }); When I click on a link, lets say "logout," and the menu reloads with the updated login status, none of the links now work because I would need to add a new .click into the callback code. Now with repeated clicks and AJAX requests I am not sure how to move forward from here, as I am sure nested callbacks are not optimal. What would be the best way to do this? Do I include the .click event inside the actual AJAX file being pulled from the server, instead of within index.php? Or can I somehow reload the DOM? Thanks for the help!
