I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code) 2. I modify an attribute of <param> using attr() and I put the result in a var (newcode) 3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?
I want to modify a local variable of the ready function set like so: $(function () { var modifyme = 0; ... }); I cant change the code setting the ready function, as I am writing only a greasemonkey userscript. I already tried using the .data("events") method, but it never listed the "ready" event. Any function so I can modify the variable!
This is a FAQ page I built with custom jquery function that toggles the answers open/closed on click of a question, and Im just wondering if anyone has a suggestion to make the code leaner and meaner:
Since jQuery parses the entire dom first, is there any efficiency gain in directing it via the entire CSS chain rather than directly to an ID? That is, if I have a Div with an ID of "foo" and it contains a P with an ID of "bar", is there any speed advantage in using $(div#foo p#bar) as opposed to just using $(p#bar), assuming jQuery would be more efficient if it had both indexes?
I am very exciting about jQuery but a am not programmer and the way I write functions is probably not most efficient. For example I have 12 collapsible panel that I need to control. Is there better way of writing this?
I am populating a number of Select boxes on the server-side with a large number of options. I'd like to get the response size down without taxing the client browser too much. What do you think is the most efficient way to approach this problem?
Here are some considerations: The option text/values do not change very often, but could potentially change in the future. The page that holds the select boxes should never be cached, there are other aspects of the page that need to remain fresh. Firebug with YSlow is saying that the primed cache size of the page is 300Kb with all the select dropdowns and options, if I remove the options, the primed cache size of the page is 80Kb. I am considering breaking out the text/value pairs for the select boxes into a separate file that is cache-able calling it "valueTextPairs.js" and referencing it with a query string and some sort of server-generated MD5 hash of the data, so that if any of the values change, the client's cached version will be replaced by the latest version. Like so:[URL]...
Provided I do this, I anticipate that the primed cache size of the page will be reduced down to 80Kb (which I like) -- however, before I take the plunge, I am curious what you all think the performance effect will be?
I know the number of bytes on the wire will be reduced, but will this put a lot of additional pressure on the client's browser because I'd need to traverse the name/value pairs and add the options to the select boxes dynamically on the client end? If it seems reasonable to do this, what jQuery approach would be the most efficient? $('#selectId').html(options) with options = one big string? Adding each child option to the select in a loop? Something else?
Some client end folks are using IE6 so I am trying to tax the browser as little as possible, while also reducing the size of each request, trying to find a happy medium..
I have been starting to use Javascript a lot lately and I wanted to check with the "group" to get your thoughts on code efficiency. First, is there a good site/book that talks about good and bad ways to code. The reason I ask is because I was just thinking about the following...which is better and/or why?
document.forms["myform"].elements["txtname"].value or document.myform.txtname.value
I have two grids, they both display buttons. One grid displays numbers, true or false and yes or no, and the other grid displays letters, true, false, yes and no.
The second grid is not displayed in the code (used css to not display second grid buttons (.answerBtns)) Now using the getButtons() function, if the user selects button "1" in first grid (the grid which you have to open using (Open Grid) link, then it should display button "A" in second grid, if user selects button "2" in first grid, then it should displays buttons "A" and "B" in second grid, if "3" then display "A", "B" and "C" and so on.
Now except using if statements and stating which buttons should be displayed and not displayed depending on the button chosen in first grid, is there a more efficent way of coding this so that the display of buttons in second grid depends on what is selected in the first grid?
If it is using an array can somebody show a sample of this in their answer. You can just do it for one example and then I should be able to use that to fill it for the other buttons.
I have some tables with rows greater than 100 and this brings client-side sorters to their knees... Any recommendations on a good, front-end table sorter?
I'm trying to build a table that has hidden rows below certain shown rows.
How would I modify this script so that it shows all of the hidden rows below a row, but not the hidden rows throughout the entire table?
$ ( document )
[Code].....
You can see the HTML table structure here, as well as it working with only 1 row. URL] I was able to get all the hidden rows throughout the entire table to show, but that's not what i'm looking for. I just want the hidden rows that are below their respective shown table rows.
We have a need to modify the actual css style definitions dynamically.We can successfully modify css class styles via the following steps. It seems to work fine in ie and firefox.
Does anyone know of a reason it might cause problems?[code]...
As title: $.readyList is not exposed after 1.4. but it is very useful for our projects. we save this list and call all method in it after doing some ajax operations.
assist with how to modify a specific css value of an object? For example, I want to do over all children of "body", and see if they have any css attributes containing a url(xxxxx) part. If so, I would like to make some change to that url (replace it with something else).
This post is about the jquery validation plugin. I am using the url() method to validate text fields for valid url input. It works fine, but I want a slight modification where I am checking whether a base directory has been added and not some individual page. For example, not [URL] but [URL]. Any way I can modify that url method to satisfy my needs?
Whenever execute the following code, the URL that is formed has "?" before my name and an "=" before my value (so the URL would be "[URL]"). I need the URL formatted so that a "+" is in front of the name and a ":" (colon) to be before the value (i.e. formatted like "[URL]"). Is there a way to change this behavior? $.ajax({ url: lansaUrl('proc', 'func'), global: true, cache: false, type: "GET", data: ({"acct": object.value}), dataType: "json", success: function(result){ $("p#customerInfo").innerHTML += " "+result; }, error: function(xhr, desc, exceptionobj) { alert(xhr.responseText); }});
I have a problem with ajax URL, I need to change and append "/" before the reale URL. Below the example ajax request: $get("mypage.php"...... I need to append "/" before mypage.php, and so modify the ajax url request. I tried with ajaxSetup beforesend without success...
I'm using a CMS, and what I want is do a ../ before submitting. My idea is on focusing on a dropdown or textbox, the url will do a ../, so that when clicking submit, I'll be able to see the result I wanted. Is it possible?
I'm receiving html into a variable from an external source and I'm trying to modify the id of one of the inputs within the html but when I change it, the original html isn't getting updated. an example of what I'm trying to do is :
var sTemp = "<div><input type='hidden' name='test' id='test' /></div>"; $("#test", sTemp).attr("id","newid"); after changing the attribute, sTemp still contains the original code
It is a "content slider" that rotates content "slides". It is setup to auto rotate on a set time, and you can also hit the previous/next buttons to move through the slides. This has been working great. Now I have the need for a pause button that will stop the auto rotate. I think this should be fairly easy for someone familiar with javascript and jQuery.
