I'm trying to extract a value from an attribute, namely listid in this case, inside an input tag.code...
$list is an associative array fetched from a database. The contents of that array might be irrelevant for the issue. I'm using a jQuery to handle any javascript code. How do I extract $list['id'] from this input tag?
or is there another genius way to accomplish the same other than using an input tag?
I like to ask about how do I get a partial attribute value? My code:
<a href="#" id="id-1">Link 1</a> <a href="#" id="id-2">Link 2</a> <a href="#" id="id-3">Link 3</a> I like to extract link attribute value in id-x, so I'll get numeric 1 or 2 or 3.
I have quite a few calls on my page at different points to populate dropdowns using jSon responses from the server. It is all working fine now apart from one issue. The name of the field that sets the value and text of the new Option(s) being put into the dropdown.

i have found a possible bug in 1.4 but it's only in Internet Explorer 7 & 8.The following code does not work and completely ruins every peice of jquery on the page (that means everything inside $(document).ready and anyting else...
$("<div/>",{
id: 'tooltip-'+rand,
class: 'dock-tooltip',
[code]....
I cant see any syntax errors - i pulled the example from the 1.4 site. There is no trailing commas in the object notation and i really cant see any reason it would work in firefox and not IEx and more to the point not only not work in IEx but break any other jquery in the entire page....
I'm working with a large (and unweildy) ASP.NET application, and there is a lot of jQuery code that uses selectors like this:
[name=_aspnetControl$_withASubControl] And unfortunately, some selectors that also look like this:
[name^=_someAspNetControl$_radioButtonList].
In other words, the effort to remove the $ from the attribute selectors would be monumental. If it is possible to escape the $ symbols, I can do that easily enough, but unfortunately the situation right now means that I can't upgrade to jQuery 1.5.
I'm learning jQuery with XML. I'm familiar with other query languages such as XPath.

In my form, i have around 20 textbox. I want to validate all the textbox. It should accept numbers and decimals. I have the following code...
How can i make the call generic to all the textbox?
I have 40 or 50 inputs scattered among many pages that all need the
ability to open a popup which allows the user to navigate a file
directory structure, locate a specific file, and return the fully
qualified file name to the parent window input. All the 40 or 50 inputs
have unique IDs. Given any one input ID, I have everything working
perfectly: the parent form opens the popup using
window.open("FileFinder.aspx?dir=" + UserRootDirectory + "&InPutID=" +
IdCodeInOnClick);
Popup talks back to parent using window.opener.document...
Like I said, give me the input field ID and I can make everything work
every time... but it makes NO sense to write 40 or 50 functions, one
for each unique input field. I tried using
window.opener.document.forms[0].getElementByID(InPutID).value
but I keep getting an error message about something requiring an
object. Is there a way to accomplish this? Also, since I'm new to
JavaScript (and web programming generally), is there a good tool for
debugging JavaScript intended for IE?
I am looking for a generic form validation script for my personal
project. I found few out there in search but nothing too close to what I want.
If I have a form in a page I want to call the javascript valdiation
routine and display all elements error messages in one validation to
their parentNode.
I found few routines which displays error message in alerts and that
too validation for one element at a time.
Can any one point me to open source generic form validations.
I'm trying to write a generic/reusable form validator in Javascript...
just something that checks to make sure required fields have a value. By
generic I mean I don't want to explicitly reference the name/id of the
form or the name of any of the data fields within a "validation"
function.
My first shot seems to have some errors in it:
FieldsToValidateByForm = {};
FieldsToValidateByForm['contact'] = ["FirstName",
"LastName","State","Email"];
function validate(form)
{
problemFields = new Array();
returnval = true;
FieldsToValidate = FieldsToValidateByForm[form.id];
for(i=0; i < FieldsToValidate.length; i++) {
fieldInQuestion = form[FieldsToValidate[i]];
if(fieldInQuestion.value.length < 1) //problem spot?
problemFields.push(FieldsToValidate[i]);
}
if(problemFields.length > 0) {
returnval = false;
warn(problemFields); /* tells user they're missing a field,
that's all */
}
return returnval;
}
What I think is happening (not sure) is that the expression
form[fieldsToValidate[i]] is not giving me what I want: a reference to
the object corresponding to the form field with the same name. In
otherwords, I must have some fundamental misunderstanding of how the DOM
works here. Unfortunately, I can't seem to find a good enough reference
to set me straight....

My page has a form comprised of several radio buttons. I want to poll the
buttons to determine which button was selected and convert its value to a
string. I then want to use the string on the same page. Code:
ok i have a script which will make a copy of the html in a div and place it into another div the problem with this it creates a duplicate element with the same id so what i want to know is can i create a new id based off old ids using a generic type script
function scope(e)
{
var popin = document.getElementById('popin');
[code]....
I want to write a generic clearForm function to clear the form when
the user click CLEAR button.
Here's my attempts, because I want to take care all html controls. I
think I need to test if the control is submit button, regular button. But I don't know
what I should do on drop down box?
function clearForm()
{var i=0;
for (i=0; i<InputForm.elements.length-1; i++)
{var obj = InputForm.elements[i];
document.write(obj.type); //runtime error: object doesn't support
this property or method
if (obj.type != "submit" && obj.type != "button")
obj.value = "";
}}
I want to learn more about creating functions for element events
without having to put onclick event in every tag. For example:
<script>
document.getElementsByTagName('input').onclick = function () {
alert('hello');
}
</script>
Now, I know the above does not work as I have tried it but hopefully
the idea of what I am trying to achieve here. Basically for every input
tag, when the user triggers the event (click) it will do the same
function.
Anyway, I would more so like to learn about this type of scripting
where you assign functions to events. However, I dont know what to
search for in google and the like. Where could I learn more about this?
Is it possible to have a generic script that set the input focus on the first valid element in a document (not hidden or disabled) ?
This script is at the end of a document, but don't work.
<script type="text/javascript">
document.forms[0].elements[0].focus();
</script>
I have a lot of similar instances of the following code on my page:
$('#btnEditParty').click(function () {
$.ajax({
type: "POST",
url: "WardAdmin.aspx/GetParty",
[Code]....
I'd like to create a generic function to save repeating a lot of code and then just pass in the relevant values.
I'm fine with that, the only thing I'm not sure about is if/how I can pass in a function name to be called on success/fail.
This post is where I was doing something similar to save repeated code: [URL]
In a similar way is there a way of passing in a function name to be called on success?
I'll trying to tell the difference between the following three cases:
<img alt="text string" />
<img alt="" />
<img />
I can do this in Firefox with the following code, where elem is the
HTMLElement representing each image, but IE doesn't seem to
differentiate between empty string and undefined.
var alt = elem.getAttribute('alt');
alt = (alt) ? alt : ((alt===null) ? 'really_null' : "");
The desired output from running this code on the 3 tags above is:
text string
really_null
It seems like this should be really easy...but I'm having a really
difficult time trying to figure out what's going on...
I'm trying to extract just the number after the string "page/"
/store/page/1/sku/232434
/store/page/6/sku/323342
So the result would be:
1
for the first example
6
for the second example
The value I'm trying to get at will always appear after the "page/" Is there a way I can do this using jquery or some other way perhaps?
I need to extract some data from the following block:<span <aref="localhost:80/items/2">item link</a> <span>item attribute</span></span> I can get the item link anditem attributedata by using $("span a") and$("span span"). I, however, can't figure out how to extract the "2" from the "localhost:80/items/2".

I stumbled across jQuery while during a search for my project that involves parsing and extracting content from HTML pages. I have a collection of xpath strings that identifies the data I would like to extract. Wondering if I could use jQuery for this purpose.
