JQuery :: Using .delegate() Method For Table Elements
Jul 28, 2010
I've an HTML table that uses the jQuery-datatables plug-in. One of the columns in the table includes a button for adding a new row to the table immediately following the row where the button was clicked from.
I'm using jQuery 1.4.4 andI can't understand where I'm doing wrong, I'm simply populating all the rows of a table with template function, so far so good, but I cant delegate the "hover" (and click and all the events) event on a row or a cell.
I've tried to put the .delegate() code also in the footer of my page but nothing.
I use $().load() to place an HTML snippet from the server into a dialog box which i then need to position relative to the size of the element which has just had the HTML loaded into it. When the main HTML page DOM is ready, I hide() the dialog box, and then use fadeIn() to show with various click() events. I have managed to position the dialog box in the centre of the screen given that there is no content loaded.
However, it seems that when I load the new content into the dialog box the new dimensions aren't taken into account untill the next time load() is called.
Is there a way to get the new dimensions of the element before the dialog is shown in order to position it centre screen?
Here is my code:
function showDialogBox(sender) { var width = $(document).width(); var height = $(document).height();
I have problem getting dynamic form elements values created with .append method when submitting the form with POST method in Firefox. It seems to work only on Internet Explorer.
I'm having a problem where the serialize method isn't serializing form elements that are added to the DOM after the page load. Specifically, when the user clicks on a button some elements are displayed in a dialog that are generated from my server and returned via AJAX. I'm converting from Prototype and didn't run into this problem.
I have written some JavaScript that I can use to remove a table row from a table. If I have the table:
[Code]...
I also have JavaScript that will add a row to the same table. I've found that if I add a bunch of rows, when I delete one, there is a small amount of whitespace added between the permanent row and the others. It seems like while the row is removed, some remnants of it remain. Is there a way to get rid of it completely?
Here is what I have at [URL]...Basically I setup a function for message selection that will call an AJAX request. Once content is loaded via .html() in my #messages div, I could not click links from within and have to use .delegate().
The code works fine when I copy and paste code from my message_click function, but if I access the function from within .delegate(), it does not work. Is it possible to use a predefined function with .delegate() or will I have to continue to reuse code?
I've selected multiple tables and tried to use each for applying cornering to each table. Inside the callback function, I try to find the first/last table cells to apply cornering for each corner. However, when there are multiple tables it looks at _all_ the tr elements for the first/last rows. See example code:
// Add cornering to tables $('table.corner-me').addClass('ui-corner-all').each(function(){ var $table = $(this); $table.find('tr:first :first-child').addClass('ui-corner-tl');
So I have a form with a few tables in it. One of these tables is to enter new values, and the rest of the tables are to update existing values. I need to be able to empty all values of elements within the table for entering new values on a button click, but I'm having trouble doing this with jquery.
I'm trying to find all elements inside of the table with id of "new_details" and then set all text box values to "" and uncheck all checkboxes but I'm not getting anywhere.
Why this submit event is not executing? It works fine if I change it to a "click" event and serialize the submit buttons parent form but I'd like to know why wont this work? [code] $(dialog).delegate("form#stayplanselect", "submit", function(event) { event.preventDefault(); $.post("/admin/viewer/rates", $(this).serialize(), processResponse); }); [/code]
I've used nice livequery plugin for many things, not just for binding events. Now when jquery1.4.2 is out it seems like it is time to replace $.livequery() with new .delegate() or even .live(), but browser events like (ready) does not work. Am I using the incorrect event (with delegate)? For example I am using livequery:
$('ul.fileList li').livequery(function(){ var oi =$(this); // DOM manipulation, appending menus and attaching plugins and so on
I have a dropdown box and a div. Depending on what is selected in the dropdown box, different content is appended to the div using the jQuery append function. This is working without problems. But, when I append DOM that should trigger events, I am using the delegate method to accomplish this. That is also working without problems, but not with the tooltip plugin. Let me try to illustrate what I mean with some code.
jQuery
HTML
Using Firebug, the "inside delegate" is indeed printed in the console every time I hover over the text, but nothing happens with the tooltip. I have tried to insert the text directly into HTML without appending it with jQuery, removing the delegate and then it works perfectly. For some reason beyond my knowledge, I can not get the plugin to work when I append the text and use the delegate method to set the event.
I am designing a game that will require a 30 to 90 second timer (depending on user preference). I have a perfectly good working two digit timer and would like to adapt to create a thick colored line that shrinks in size as timer counts down.
I cannot find any examples. This should be relatively straight forward to do with a one row table of 30 to 90 cells filled with colour with each cell given a unique id to remove the colour with each second. Is there a better method?
why the following code (which counts the remaining allowed chars in html-textarea) does not work in Firefox although it works in all other browsers, IE including?
I'm new in jQuery. I have to alter randomly the order of the td elements of a table. My initial idea is: - Clone the original table (I can't modify it). - Disorder randomly the elements of the cloned table. - Show the cloned table.
The actual code is: <html> <head> <script src="[URL]"></script> <script type="text/javascript"> $(document).ready(function(){ }); </script></head> <body><script> $(document).ready(function(){ .....
I have now been playing around for hours trying to figure this out. Swore I would not ask for a solution. Now I have a headache, so I am asking. On one HTML Page (From.htm) I have:
[Code]...
I somehow, need to get the values as shown in the handle function for each of Products shown in From.htm. Keep in mind the only thing I know from From.htm is the class names. I have no idea what products are listed or what the input names are. This table is generated by a third party. Assume that index.htm and From.htm are on the same website.
I have a table of input elements which i create through a javascript widget. When i press submit i want to make an action and a part of the output should be the same unchanged tables with the values in it. I don't know how to accomplish it. At first i used the html() function, but it does not pass the table with the html values inserted as i would like.
I need to be able to call a certain td element in a table and I'm not able to edit the html (dynamically generated) so i was wondering if it is possible to target td elements like an array using jquery.
For instance, say I need to change the class of the 4th td element in the second tr element. how would I target that? is there a way to do it in array style like below?
