I need to pass a variable into a URL but need to replace the spaces with
$.ajax({
beforeSend: function(){$('#loading').show();},
type: "GET",
[code]....
This line replaces only the first " " spec. character in my textarea, and this way everything's screwed up... I'm sending the replaced content of the textarea through AJAX to the server, in a GET method. I've tried to just comment out this line to see whether this is necesarry, but then no " " is transferred at all... I'm using a PHP server side, and that works.

Say I have some CSS, which is several hundred lines long, with the
contents in this format:
..foo {
blah
color:#000;
blah
}
..bar {
blah
color:#FFF;
}
where the selectors and their opening braces, their closing braces, and
declarations are each on their own lines (always), how can I replace a
specific declaration (line) given a unique selector and a declaration
property. For example, if I wanted the 'color' declaration property line
in the 'bar' class changed.
At the moment I'm iterating through the CSS one line at a time looking
for the selector and then looking for the declaration property (before I
hit the closing brace).
I'm trying to create a piece of code that will check a webpage and replace any instances of a specific line of HTML with another line of HTML. The code I have so far doesn't work, but I have a feeling that's down to my awful Javascript skills! For example, in the following code I'd want to replace all instances of
<li><a href="index.pdf">Index</a></li> with <li><a href="contents.pdf">Contents</a></li>
<div id="downloads">
<p>Please click on your downloads below:</p>
<ul>
<li><a href="index.pdf">Index</a></li>
<li><a href="chapter1.pdf">Chapter 1</a></li>
<li><a href="chapter2.pdf">Chapter 2</a></li>
<li><a href="chapter3.pdf">Chapter 3</a></li>
<li><a href="credits.pdf">Credits</a></li>
</ul>
</div>
The Javascript I have so far is:
<script type="text/javascript">
var aEls = document.getElementsByTagName('a');
for (var i = 0, aEl; aEl = aEls[i]; i++) {
aEl.href = aEl.href.replace('index.pdf','contents.pdf');
}
Obviously this is meant to just replaces the a href elements, but I got a bit stuck after this!

The replace function only removes the first instance. How can I remove all of them?
I would like to check if a string is a valid zip code via Javascript.
Length and existents are already checked.
How can I find out if the string contains characters other than numbers?
Example: 834F7
schould be false since it countains an F character
I'm looking for a way to find all prices within a string and process them and display the results before the browser displays.I would need to be able to recognise eg 100 or $99.99 etc.. or even their html characters.
View 3 Replies View RelatedHow can I check if a number exists by itself in this string by using
the RegExp object?
var mystring = "11,111,01,011";
var match = "1";
var re = new RegExp( match );
var isFound = re.test( mystring ) );
Running this code returns 'true' which is not what I want since number
one doesn't exist by itself. I need to use the "match" variable since
it will change depending on user input.
I can only get it to work without variables in the expression. E.g.
var re = new RegExp( /1/ );
this is simple, but:
function printInput(f){
var ifr = window.frames['printFrame'];
var v1=readCookie('lesson');
if (v1==1){v2='WORKNOTEPAD1'}
[Code]....
How can I make it stop erroring and act as if the "v2" were, say, "WORKNOTEPAD2"?
If the line contains the string it all works fine.

I have a iframe element which currently has a small amount of javascript that handles the scrolltop and I am trying to add a variable to that which controls the height of the iframe based on the source height. I do not want to set the height of the iframe in CSS because if I use this same method for other iframes and the source height is not the same it will not work.The page with the iframe is here (click on the link on the top of the page to load the iframe):
[URL]
The page I want to load into the iframe is here:
[URL]
The javascript and html for the parent page is:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
[code]...
Again, what I need is for the iframe to get the document height from the page that will load into the iframe and then have the iframe height be that exact size. As you can see once you click on the link it is much shorter than the page I am using to load into the iframe.I do not know javascript enough to figure it out and have spent a couple days looking all over the internet and have yet to find something I can incorporate into the javascript I already have.
I have a for loop: Code: for( var i = 0; i < aInput.length; i++ ) I want to use this i variable to concatonate it as a string to find an input box
Code:
var j = i;

qualname.toString();
if ( inputName == ( qualname ) )
{
Assuming I have a input box named discountqualifier0, discountqualifier1, discountqualifier2 etc...
$displaytext = "display this text";
$(".image").mouseenter(function(){

I have this image gallery in which clients should be able to determine the order in which their images are shown. The sortable part works. Then I want to pass the new order to the next page called act_writeneworder.cfm (i am using coldfusion)
I just started with jQuery and it is driving me nuts:-) Each time I think I am having it well i am testing and the variable passed through gives an empty string.

I have an object whose name is mural. I have assigned the name mural to the title of an anchor element. When user clicks and element I want to store the title of the anchor in a variable called sprite. I then want to access that object whose name corresponds to the sprite variable string.
Here is my code:
HTML Code:
var mural= new Object();
mural.top='0px';
mural.left=-'510px';
var stamps= new Object();
stamps.top='0px';
stamps.left=-'1886px';
var sprite=$(this).attr('title');
$(".image-holder").css("background-position",'sprite.top, sprite.left');
It's not working because the the variable sprite is just a reference to $(this).attr('title'), how do I make it reference the object? Oh and I know that .cc jquery statement probably wont work, I'm not sure yet of the correct way to have two values that don't need quotations in as the second argument.
What I need to get is something like this :
<script>var my_var = "<p>Hello</p>";
But I need this content to be builded in PHP, from an external file.So I tried this :
var my_var = $.ajax({
type: "POST",
url: "<?php echo $config["root_url"]; ?>/www/ajax_queries.php",

Two objects on an html page. An event on object 1 effects object 2
$(".video_rg").mouseover(function(event){
var myTriggerId = event.target.id;
var myTargetId = 'video_' + myTriggerId;
document.getElementById(myTargetId).src = 'images/test_object_2.gif'; // this works
// $('#myTargetId').src = 'images/test_object_2.gif'; // this does not
});
My assumption (we know about those) is that I am not passing the data to the $() function correctly, that it is reading '#myTargetId' as a string, and not a variable. I just really want the JQuery code that would do what the document.getElementById code is doing.
I'm writing a debugging script and I'm passing a function an object to iterate through:
myObject = {a:1,b:2}
debug(myObject);
I'm wondering if there is any way to get the variable's name as a string("myObject"), so something like a .name property:
function debug(obj) {
alert(obj.name); // would alert "myObject"
}
Is there any way to do this?
I need to look at the url, if a variable is present in the query string.

var previous = document.getElementById("chat").innerHTML;
var matchPos = previous.search(newMessage);

Say I had a bunch of elements with id names "id1", "id2". "id3" etc. Then say I had a function that adds a click handler such that when you click these elements it gets the id name with this.attributes[1].nodeValue;Then say I had a bunch of arrays with the same names as the ids var id1 = ["data", false, 45]; var id2 = ["otherdata", true, 15]; var id3 = ["otherotherdata", null, 65];. How would I set a variable "currentid" to the array with the corresponding name as the id name? I guess the underlying question is, how would I convert a string to a variable name?
View 1 Replies View RelatedI have a javascript program that currently takes the contents of a *.txt file and converts it to a string-type variable using a hidden iframe.
For my pruposes it would be much nicer to read a *.csv file instead, however the method I'm using creates the "open/save file" pop-up window.
All files are client-side and in the same folder on one computer; this is NOT server-side or internet-based. It is simply javascript used in an HTA file as programming code. The *.csv does not need to be edited, just read.
I need to know how to convert the text of this *.csv file into a string variable. I have heard of using "xmlHTTPRequest (AJAX)" but am not familiar with how to use this.
