How do I fetch the ID with jQuery? What I want to do is to fetch it and then display content in a <div> that depends on the ID value. Do you know how to do that?

I'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.
If I had a table like this...
.change() is only for form elements minus check boxes/radio buttons, etc.Are any of you aware of a script that does this already? Hopefully one that is easy to implement.I just want to monitor things like height, number of inner elements, or any change in the inner HTML.

I have a page where I do:

e.src = "myimg.jpg";

I'm working on a navigation menu where I want to insert some html after a UL element.
Here's the statement:
selUL.eq(x+1).after('<b>hello</b></div><div class="subMenu">');
I'm trying to insert it after the following <ul> element:
<div class="subMenu">
<ul
[Code]...
It's like it's trying to auto correct me. I need it to print everything exactly as I have it, otherwise my navigation won't divide into separate columns. Anyone have an idea why it's doing this? If I remove the <div> elements and just use the <b> element it works fine.
EDIT: After some more testing, the After method seems to strip out any closing elements not yet opened (</div>) and automatically closes any elements opened but not closed (<div class="subMenu">). Anyone know of a way to stop this from happening?
I'm trying to get an unordered list and its children as an HTML string on a mouseout event, but html()only selects the child elements:var theHtml = $('ul', this).html();I've tried using andSelf(), but that doesn't return the result I want:var theHtml =$('ul',this).and Self(). html();I can't choose $(this).html() as I need only the list.
View 2 Replies View RelatedI am creating a <select> with options, and I want to include such html entities as the Ohm/Omega symbol (Ω)When I say

I am using $().html to manipulate DOM elements, as an example:
jQuery('#basic).html(..some data...);
I then alter the DOM using a div and id as part of the HTML document. For example.
<div id='basic>change this</div>
This is absolutely fine when manipulating simple things (like numbers or text such as the above) - but when I wish to manipulate a specific attribute of an element wrapped within a div
<div id=basic>
<a href="I-want-to-alter-just-this-attribute">Link</a>
</div>
How do I do this?
I can't nest the div within the a element :(
At the moment I am using $().html to insert the entire element and its attribute list, but this is very cumbersome,inelegantand fault prone (and doesn't seem to work well using JSON).
I can't seem to find a method to Modify Attribute !!
I'm making a site for my g/f – She's writing angel messages for each day of the year, 1 message on 1 page and these (eventually 366 pages) are accessed from this one page:
[URL]
This menu page uses JS to slide to particular months. The place I'm stuck is how could it be possible to go from a particular days message, back to the month of that message in the per-datum page (having the page slid to that month)...
for clarities sake... “Terug” means “back”, so for example to click on october 22nd message, read the message, and terug back to Octobers seeds rather than back to the per datum pages month selection calender.
My best effort so far is to put this in the a tag:
onclick="document.getElementById('waarzegstermove').style.cssText='left: -1000px;';"
-1000px would be Januarys terugs, -2000px Februarys terugs etc to have it already slid to that month, this code works when on the same page, but when its on the message page before loading up the per datum page it seems to lose this setting.
I would like to write a script that will highlight any html element in a page (or maybe just divs) onclick, and print out the name of that element on the top of the screen somehow. I cannot make any major adjustments to this html, just insert a script because this will need to work for user submitted html pages
View 7 Replies View Relatedi'm removing a bit of html once the page has loaded with js (a message for non-js people) but that makes the page jump sometimes so i want to remove it earlier, as the page is being written/output like how document.write works. i thought of this which seems to work ok:
Code:
<script type="text/javascript">document.write('x3C!--');</script>
<p>HTML element not to be seen by people with JS</p>
<script type="text/javascript">document.write('--x3E');</script>
it comments out the bit of html i want to remove for js viewers. is that the best way to do it? is there a bit less verbose one maybe?
I've seen lots of examples of invoking the getElementById and they always are given as a method of the document object. That is, they always show something like:
Code:
var theElement = document.getElementById("Fred");
But what I'd really like to do is to get an element from the document, but starting at a particular element in the hierarchy of the document.
For example, suppose I have two forms, form1 and form2, and they both have elements in them named "Fred" (and, yes, I know I shouldn't do that). But what I'd really like to do is something like:
Code:
var theElement = form1Element.getElementById("Fred");
assuming that I've already somehow retrieved the form1Element.
But Javascript reports to me that getElementById is not a method of form1Element. And the fact that every example I've ever seen of getElementById invokes it as a method of document would seem to bear that out. The thing is, on the microsoft site it actually shows the generic form of the method as:
Code:
object.getElementById(iD)
Which would seem to imply that it's more generic than just being a strictly document method, that perhaps it's intended to be a method of at least some additional HTML objects. Since that doesn't seem to be the case, how might I go about doing what I'd like to d, which is find the occurrence of the element, by its ID, but only within a particular section of the document hierarchy?
I have a text box that gets its name, id, and value from a SQL query.
[Code]...
My problem is that when the page loads with the values from the SQL query, I want all of the text boxes to run their upperCase function to change their respective background colors and I cannot figure out how to do this when the correct responses and initial text box values are set from the SQL query.
I thought I was genius when I put the onload event in there (which obviously doesnt work with an input element).
In one of my webpage, I have a text field, upon double clicking on that text field, a look up table gets opened so that I can select a value on it.
There is no other way to open the lookup table other than double clicking on it.
How to double click on a text field using javascript. (In fact, how to double click on any HTML element). I cannot change the functionality of the web page to resolve this issue since the webpage was developed by me.
All I have to do is, I have to double click on the text field using javascript.
I am looking for a method to make a html element empty (no innerHTML). This would be pretty easy if it weren't for IE. IE has the bug that innerHTML is read-only for tables (and some other elements too). So my function
function clearElement(id){
document.getElementById(id).innerHTML = "";
}
doesn't work on tables (and I need it to work on tables). Would there be any other way for me to do this in a way as general as possible. I don't want to bother with 2 different functions for what is essentially the same task and I'm curious how this could be solved in a nice way.
My code that centers html elements fails when the html element is large. For example, I have a list of 443 items, which I break into 3 columns within a div. Therefore there are 148 lines in the div. When I use the code below to center the div, the top part of the div is beyond the top of the window screen.
function centerPopup(){
// Get data for centering
var windowWidth = document.documentElement.clientWidth;
var windowHeight = document.documentElement.clientHeight;
var popupHeight = $(".popupArea").height();
var popupWidth = $(".popupArea").width();
//centering
$(".popupArea").css({ "position": "absolute", "top": Math.floor(windowHeight/2)-Math.floor(popupHeight/2), "left": Math.floor(windowWidth/2)-Math.floor(popupWidth/2) });
//only need force for IE6
$(".popupBackground").css({ "height": windowHeight });
}
I'm attempting to write a quick piece of Javascript code that will
validate if the end user of the javascript has the necessary VML
attributes set in their HTML. The problem in IE is that "xmlns:v"
does not appear in their attributes property or the
getAttribute('xmlns:v') calls. The real kicker is that the 'xmlns'
attribute does return something.
The HTML Snippet would look like this:
I have tag something like
<div class='abc'>
using jquery i want to change the class dynamically.
i saw the jquery reference, it has something hasClass, but i donot see addClass.
