JQuery :: Getting Value Attribute Of Input Element ?
Oct 2, 2010
I have a table with several columns containing input elements populated from a database, e.g.,
On every row, I need to perform a calculation using the value of several input fields. So I tried to access the value of the first input field like so (which had worked in another function):
But for some reason it's returning a 0, and the line below also doesn't work:
But this returns the correct class, so I know it's finding the element:
And if I assign the input element an id, say "count," this works:
Obviously I don't want to fuss with individual id's to get the values. How to understand why the first two examples don't work, and how to fix them?
I'm attempting to submit a form via a function which dynamically creates a hidden input:
function submitLocation(theForm) { var e = document.createElement('input'); e.setAttribute('type', 'hidden'); e.setAttribute('name', 'location'); e.setAttribute('value', Ƈ'); var f = document.getElementById(theForm); f.appendChild(e); document.forms[theForm].submit(); }
The function is called from an anchor's onclick event:
I am just working on a project where i have to replace the href-attributes of all links by another string. The problem is, that i need the old href-attribute to generate the new one, and i have no idea how to get it
i tried it with something like this, but it doesnt work [code]...
I know there is some way to do it but i forgot it and i looked up the whole internet for it and didnt find it
What I’m trying to accomplish is set an attribute called opacityin any element with a specified value that can be used to toggle whenever the user hovers over the element. The code below works perfectly but one other thing I would like to be able to do is retrieve the attribute opacity after the document loads and fade the element to that value instead of hard coding the ".66". This is probably fairly easy I've just never ran into a situation where I needed to do this.[code]...
I quite like the fact that you may add through JQuery an attribute like alt or title to an element. And I can see that you may also add mouseover using: $('#aa').mouseover(function(){//does something in here}); However, I want to be able to pass some very specific values too and that's where I'm stuck for an answer. Suppose I want to attach the following: mouseover="hm(this,'la1',5)"attribute to an <a> tag. How do I do this by using exactly those values inside the "hm(this,'la1',5)" ?
I have a standard menu structured with an unordered list. Some of the items in the menu have sub items, but are not themselves links. Here's an example:
How do I select a tag that does (or does not) have a particular attribute? In my case, I want to be able to select all <a> tags in #mainMenu that do not have the href attribute.
but none seem to be working. The img gets generated by another script so I can't add an id or class to it. I figured an expert at selectors would be able to explain how to select it.
I'm having trouble finding the image element by attribute "MyAttr" whose value is supplied: when the "onclick" function is called: <div class="MyImages"> <div class="imageClass"> <img ... myAttr="abc"/> </div><div> <img ... onclick="findTheImageObjectByMyAttr("abc");" /> </div><div class="imageClass"> <img ... myAttr="def" /> </div><div> <img ... onclick="findTheImageObjectByMyAttr("def");" /> </div></div>
I have a set of elements with the same function attached, how do I get the ID or other attribute value of the element that caused the function to be called?
but having fun with it. Would like tolearn how to do the following...2) Find the parent <li>.3) Grab the value of the attribute "jcarouselindex" and put it in avariable to be used elsewhere.Sample code below...
Is this possible with JQuery? I have the following code which I think Should do this, but it's not working :/These are two different functions which I've been testing, and the html element is supposed to create a dropdown list via some PHP which will have the option "Other" within it. Unfortunately, I have no idea exactly how to turn "Other" into a text box when the user clicks, and I've been spending a lot of time on this already.
I have a page which contains an <ul> list with 5 items. Each of those items has a data-weight attribute which corresponds to its importance in the list. I have to make only one random list item appear and use the weight to make sure that the most important one shows up more often than the least important item.
The technique for getting the name of a span element should be just like getting the name of any other element, I would think... but it doesn't work in FF or Chrome. Here's some example code:
<script type='text/javascript'> function test(el){ var boink = document.getElementById('boink');
Is there a way I can make this code work: <script type="text/javascript"> function changeText(){ document.getElementById('boldStuff').innerHTML = 'Fred Flinstone'; } </script> <p>Welcome to the site <b id='boldStuff'>dude</b> </p> <input type='button' onclick='changeText()' value='Change Text'/> with this: document.write('<param name=avatarID value=4>'); So when I click the form button it changes the value 4 to Fred Flinstone
The url section works fine. If i check the source code, the attribute data-zoomsrc is never displayed. However, if i write it out in the javascript, i get the value i am after:
I want to change attribute action in form. Problem is that in that form is also input with name action. Unfortunately renaming of that input is worst case because many servlets depend on it.
This works in konqueror but not in IE and Mozilla:
When accessing my web page I build up the javascript and html dynamically. Depending on an parameter I want to set all the fields (input tags) readonly. How do I do this? Of course I can write if statements to add different input tags with and without the readonly attribute. But is it possible to write a javascript that onload search the page and add readonly to all input tags?
I just have a question regarding the wrap attribute of the <textarea> element. I am using Programmer's Notepad. I am doing an example using the split() method in JavaScript. On the <textarea> element, it has specified that I use the 'wrap' attribute, yet when I enter this code, my attribute highlights red (which usually means that you have made a spelling mistake with the element/attribute). Now, obviously I know I haven't spelt wrap wrong and it certainly tells me in this book that you can use this attribute, so is this attribute deprecated?
