I'm receiving html into a variable from an external source and I'm trying to modify the id of one of the inputs within the html but when I change it, the original html isn't getting updated. an example of what I'm trying to do is :
var sTemp = "<div><input type='hidden' name='test' id='test' /></div>";
$("#test", sTemp).attr("id","newid");
after changing the attribute, sTemp still contains the original code

I'm trying to get the following function to work:
When called like so:
I could just give each image an ID and not use the 'this' keyword, but I haven't used it much so I'm curious about it. It's sending the image element to the function, so why can't I modify the src attribute with that information?
I have following HTML code:
<br/>
<div style="display:none">.....</div>
<div style="display:none">.....</div>
How can I modify display to block in style attribute with Javascript?
I am currently trying to build a new function in javascript that is supposed to handle a string of text. The idea is that it should find the lowercase letters and uppercase letters in a string and then swap them.
Meaning all lowercase letter becomes uppercase letter and vice versa.
So i am just asking if someone could point me in the right direction or give some tips. I've currently been reading about the toUpperCase(); and toLowerCase(); functions and i am fairly confident i know how to use them for switching, however i still need a way to find the lower , upper character in the string so i later can switch them.
String.prototype.trim = function(){
return this.replace(/^s+|s+$/g, "");
}

It's possible with numbers:
var myNum = 10;
myNum++;
alert(myNum); //11
When I click the name, I should go the particular page about that person.

I'm trying to get the width of the elements contained in a div. At the moment that was my best try : $("div.mydiv").children().width(); But all I get is the width of the first child.
What I need is the width of child1 + child2 + child3 etc.... each child might have a different width and they can be a div or an image <img>.
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....
One label, one textarea with some text content in it,

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 have an asp application contained within an Iframe. If the browser refreshes, the page within the Iframe reverts back to the login page and the user has to log on again.Is there a way to keep this from happening if a user clicks the refresh button on their browser?
View 3 Replies View RelatedBasically I have an application which generates HTML using VB dll's. This makes the code generated un-changeable as the dll's are not to me modified in any way. What I need to do is get hold of a image element so that I can switch its SRC to dynamically change the image. GetElementById is out as the nearest I can get to it is the <a> tag surrounding the <img> tag, so my question is what's the easiest and most bomb proof method of accessing this element.
View 10 Replies View RelatedHow do I use Javascript to loop through all the spreadsheets contained in 1 excel file?
I am now at the stage where I can open the Excel file and find a value on 1 spreadsheet. Is there any way to detect if the workbook has multiple spreadsheets and then loop through all the spreadsheets to find a value?
I am planning on using the maito form with Javascript. I have a form and it is structured in the following fashion:
<form>
<b>Subject </b> <input type="text" name="subject" size="30"><br>
<b>Person 1 <b><input type="checkbox" name="email" value="person1@email.com"><br>
<b>Person 2 <b><input type="checkbox" name="email" value="person2@email.com"><br>
<b>Person 3 <b><input type="checkbox" name="email" value="person3@email.com"><br>
<input type="submit" onclick="submit">
</form>
What I am trying to do with Javascript is that you fill out the subject name and then you select which recipients of email you want to receive the email. So if I select Checkbox 1 and Checkbox 3 then when I click submit, it opens my Outlook and the To is filled in with person1@email.com;person2@email.com. So I guess I would need the javascript to populate and <href mailto: form after checking which names are checked and then populating the mailto with the variable that contains the list of names I chose. Right now we have a clunky method using the mailto but I don't have the option of choosing who it mails to so when I send it, I send the mail to everyone, even those on vacation.
I'm trying to pass trough all the objects of a form but I have some text
inputs in a DIV and I have many DIVs like this on my form.
I'm doing something like:
for (i = 0; i < document.forms(0).item.length; i++) {
dosomethingwith(document.forms(0).item(i));
}
but document.forms(0).item.length are the objects that are outside the
DIVs...
How can I pass trough all the objects of a form if some of them are
contained in divs?
I have a window (it's a modal dialog as well, but let's ignore that for now), where I need to write data into an iframe. Dynamically generated data. This data contains a form, this form is then sent to a server process, which expects it to be latin1 (iso-8859-1). It arrives as UTF-8. I have set the charset both in the container html (which contains the iframes) and the iframe in question to latin1, I once toyed with accept-charset of the form as well, all was ignored. So I started to recreate the experiment step by step.
HTML, meta tag text/html charset=iso-8859-1, FORM directly in it --> data is sent as latin1 Next I put the HTML for the form into its own HTML, put an iframe into the first documented and had its src point to the new HTML. Both the new and the old HTML had charset meta tags. Form was loaded into iframe, sent properly as latin1.
I removed both metatags, we're still sending as latin1. Next I thought it might have something to do with the dynamic nature of the iframe filling. I only assigned the iframe's src at runtime. Still, latin1.
Then I took the final step, and instead of reading an html into the src of the iframe, I wrote the code into the iframe with document.write. Everything LOOKED the same, but the server now receives the form data as UTF-8.
For this experiment I am using IE 5.5 (it is our compatibility base, another browser is not an option unfortunately - I'm a straight firefox man at home), and yes, the content has to be written into the iframe dynamically. I cannot create a temp file that I would load into it, or I would much rather not (it's a rather complex performance issue)
To clarify: Soon as I'm using document.write, all meta tags and or accept-charset (or what it was called) for the form are ignored completely.
I have created a page which pulls search results from various sites using PHP. It displays each result in a row in a table upon running.
I wanted to add a button saying "More information" at which point, a div would appear and load the associated link for that search result within an iframe within the newly appeared div. I've been able to get a div appear and disappear on button click but, I couldn't get it to dynamically load an iframe on click with the associated search results link.
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 was trying to develop something where on hover of a paragraph the background colour of a div tag that contained all the content changed correspondingly.So the html is something like this:
Code HTML4Strict:
<div id="container">
<p>Change the colour</p>
</div>
I did something simple first where the text colour of the paragraph changed on hover of that paragraph. Now that works completely fine. Here is the code:
Code HTML4Strict:
<!DOCTYPE html>
<html>[code].....
but it does not work .get the latter code working so that the background of the container will change on hover of a paragraph?
I have an XML(RecentBook.xml) file like[code]...
I am able to get the values of the author and publisher.
But my requirement is to update the above XML document by changing the values of the textboxes( 'bookAuthor' and 'bookPublisher').
After entering the new values in the above text boxes the xml should modify and next time when its loaded it should give the updated values.
Can I do this by using jQuery?

You can see the HTML table structure here, as well as it working with only 1 row. URL] I was able to get all the hidden rows throughout the entire table to show, but that's not what i'm looking for. I just want the hidden rows that are below their respective shown table rows.
