JQuery :: Selector : Find & "Perform"?
Mar 5, 2010
i want to use jQuery to perform 2 action within my articles:
- create links (for a glossary), attributes needed:
href, class, title, target, link text
- highlight terms (for a search function)
first of all, for the highlight-function , i tried:
$("#content_article:contains('Test')").css("text-decoration", "underline"); but then, jQuery underlines ALL content. I just need e.g. "Test " to be underlined (or yellow-backgrounded).for the second, glossary-function .i'm using "tinyTips" for displaying tooltips above an <a> element.so i need jQuery to find e.g. the string "Test" and perform the following with it:
<a href="#" class="tTip" title="'.$glossary['desc'].'" target="_blank">'.$glossary['tag'].'</a>
.. where $glossary['tag']represents "Test" in this case.tinyTip need the "description text in the title attribute.
-> is it possible to access such elements via
???.attr("href").(???)

It is possible to perform a find in page search that looks at a specific link, opens the page in a new window and finds the text within that document?? Basically I regularly use an html page in work that has a list of people and their telephone numbers. I want to be able to type in a searchbox on my main page and it open the target page and find the name I am looking for? Is this possible or can you only Find In Page on the same page or another frame?

I'm sure this is much simpler than I have been making it seem in my head so I'm giving up and asking Basically I have a html document being dynamically created by php. In the markup I create some divs (the number of which changes between pages) all of which belong to the same class (class="div") and have id's of the same format (id="div_90001" or "div_88926773"). What I want to do is perform a function on eachelementin the class and extract the number in the id and then perform a function with the number (AJAX) and then return the results to the div (probably some extra markup)
I can handle all the AJAX parts, the extracting of the id number etc... I just can't make a function that will work on all elements in a class. I fear I am not making much sense, I'll try again cos I don't think I'd understand what's above. I have some divs that belong to a class, I want to perform the same function on each of the elements in the class. How is this done?

I'm using jquery file upload - when each file has uploaded, the name of the file appears, and I've added a check button:
<td colspan="2"><span class="ui-icon ui-icon-check"></span></td>
What I'd like to do is make jplayer fire off a "ding" sound as soon as each file is up.
For example (just to test)
$('.ui-icon-check').live('click', function() {
$(this).css("background-color","yellow");
});
needs an action, like a click or a mouseover or something. For each file that arrives, and therefore adds another instance of ui-icon-check, I'd like to fire an event. A weekend of googling has really only turned up Live Query from 2007, which works perfectly with
$('.ui-icon-check').livequery(function(){
$(this).css("background-color","yellow");
});
[Code]....
So am I totally mis-understanding the point of live, or just mis-using it?
I'm doing it this way rather than mess with the uploader code as he's updating the code all the time, and the more I can stay away from code code the better I think.

This is odd. I cannot perform a subtraction. The following code:
Code:
var saturday=new Date();
saturday.setDate(saturday.getDate()+6�saturday.getDay());
Gives me:
Error: illegal character and points to the '-'.

I have this code below:
Code:
$('#admintable').load("/includes/ajax.php?type=gallery&action=order&var=" + $.tableDnD.serialize());
The problem is that throughout my php project it calls different classes and definitions based on what modules are loaded.Is it possible to get it to load a function that is predefined rather than executing a page that will require me to once again declare all my variables and classes so I can perform just a simple db search.

I have a matrix of radio buttons:
<input type="radio" name="chcalt" id="radio33" value="1">
<input type="radio" name="chcalt" id="radio32" value="2">
<input type="radio" name="chcalt" id="radio31" value="3">
[Code].....
The colum totals would change to: 2, 0, 1 and the total would be 3
I basically need the total of each column and the total overall. The value should be taken from the actual "VALUE".

As this forum has been so helpful before, this time it's a JS question:I have a list of checkboxes from which the user can select 1 or more to check and perform an action upon.Thus, all checkboxes have the same "name" (in ASP code, since it's DB-related):
response.write "<input type=checkbox name=""FieldName"" value="&obj("OrderID").value&">"
I call JS using a button:
<img src="images/TrashBin.png" border=0 onclick="Delete(document.FormName.FieldName)">

My problem is that it takes ages to perform the element.focus() function. This is not a function I have written myself but is part of the Javascript language itself. There are probably a lot of reasons why this might be slow but I cannot find the right one. Let me describe my problem. We have a product which was created around 2004 and has been developed on since. The HTML and Javascript used for the product was based on a prototype which we then converted into a server based solution (we use Servlets/JSP).
Due to the nature of the prototype (and also the graphical layout) the major page consists of one huge HTML page which a lot of hidden DIV tags. These DIV tags are then toggled visible/invisible to make it look like we have a kind of tab functionality. We also do not load all tabs when we load the mail page, instead each tab is loaded into a hidden iframe and then with Javascript we grab the resulting HTML content and paste it into the main page, making that one tab visible while hiding all other tabs.
In one of these tabs we also do some more magic. The layout is as follows; we have sets of three columns each and then a lot of rows. Each set of three columns contains one text field per column. The last text field contains a percentage value and when edited, we check if the value is lower then before the edit and if it is, then we split the column, creating another set of three columns.
When we load the page the first time, there exists only one set of columns with the last column having the value 100. There can however easily be 100 rows as well. For the larger pages we can have (at load time) three columns which makes it 900 text fields. I do not know if this is much or not.So, with the above info, to my problem. First off, when I try to move the marker and click on a given field (so that the marker starts blinking on the selected field) it takes maybe 2-3 second (although not always, seems to be more the first time). If I then tab to the next field it goes very fast (like one would expect).When I try to edit a value (by simply adding or removing values) it again takes a very long time (the first time).
When I then try to tab, it takes ages (this happens always, not only the first time).My Javascript then. I have two events, onchange and onkeydown. onkeydown checks if a variable is set to true or not. If it is set to true, the method does nothing. If set to false it does a bunch of tests and sets the variable to true. onkeydown is what I think causes my first lag but the code is not really that advanced (no loops or anything). onchange does the same checks plus all the magic (with the split etc). One of the last things it does is try to set focus on the next text field and this goes extremely slow all the time.
We use IE8. We (sadly) have a lot of IE specific stuff so the site doesn't even work in Firefox. I have used IE8 Developer Tools and used the Profiler which basically gives a list of Javascript calls and their execution times. My own functions take basically zero time, but there are A LOT of calls to functions that are not named, or anonymous, according to the Profiler.
How do I find what the anonymous function calls are?Why is it the focus() function that takes time, can it (or is it) still some of our own Javascript that makes that function go slow, even though it is part of the Javascript language?Can it be the amount of elements on the page (900 text fields)? Is that much?Can it be IE8? Are there known issues with this?

I need to perform an Ajax request as someone is typing into a text field. But I don't want to trigger a request on every key press. What I need is to perform the request if a key has not be pressed for x number of milliseconds.I seen an answer here - Time Restraint - but I'm having difficulty applying it to my situation.I'm using jquery and this is a trimmed down version of my current code:
javascript Code:
Original
- javascript Code
I don't know how to change this function to use setTimeout in a way that lets me execute a trigger function on a control relative to the current field. Ideally I need to pass $(this) as a parameter for the function setTimeout calls, but I don't know how to do that when the function call is passed as a string.
