Info Needed On Using JS To Manipulate CSS
Apr 24, 2004
I'm starting to focus my attention on using javascript more (initially in conjunction with css) and would like to know which version of JavaScript introduced functions such as getElementByID() and such. Recommendations for good books/sites would also be appreciated. I also would like to hear where I can find good tutorials and examples of using JS to interact with CSS. One thing I am playing on playing with is using CSS/JS with forms to help users fill in required info. Hoping to make it even more obvious the famous little red asterisks by each form field.

Can someone help me on this little problem. I am using the following
code in an xsl page.
The directed page is written in the javascript: submitOnClick();
<a href="#">
<xsl:attribute name="onClick">submitOnClick();</xsl:attribute>
Main Menu
</a>
The problem is that when href is given the # sign, the moment i click
on the link it first jumps to the top of the page, before moving to
the directed page.
This can be seen when the page is longer than the screen size.
Is there any other solution to rectify that problem ..........

I want to write an if / then statement and have tried using this:
var MyVarMailto;
if (Request.Form("LoanRequest") == "Under $250,000") {
if (Request.Form("Organization") == "1") {
MyVarMailto = "emailA@address.com";
}
}
else if (Request.Form("LoanRequest") == "Over $250,000") {
if (Request.Form("Organization") == "1") {
MyVarMailto = "emailB@address.com";
}
}
else {
MyVarMailto = "emailC@address.com";
}
So basically I have a form that gets filled out and submitted which
passes the values to this page. I want to check the values against
conditions that you can probably figure out above and then set the
variable contigent to those values. I tried using AND after the first
condition but that doesn't do anything.

string using a proportional font? I would like to do this in order to

I have a form with a name, and action, a post method.
In rare occasion I want the form action to be different to the default
action, so I do this: document.formName.action = "newURL";
This works fine under Mozilla, but does not work under IE5, 5.5 or 6,
it says: Object doesn't support this property or method.
Does anyone know what could be wrong?

I am working on a website that utilizes a DHTML (HTML + Javascript) Navigation bar, but IE blocks the "ActiveX" content, despite the fact I am just using javascript. This site will be used by every computer on our network.
Is there any way I can modify the script so that it is not blocked even when this "security feature" enabled?

Does the world need another DHTML popup calendar? Probably not, but I'm writing one anyway. It's unique in that it allows drag selection of a range of dates. Works great on IE6 but I'm having some trouble with Netscape and events. In particular, the mousedown event doesn't work. The event fires, but I can't seem to get a handle on what html element was clicked.

In a nutshell, I'd like to have a list of items, each of which fills out a
small table which displays some info about a particular item(the items being
a trouble ticket for a tech support ASP-built web-based app). There may be
zero, one, or many of these per ticket. Since some tickets have many of
these items (call them work items), the page can get awful long. I have this
part working already.
So my proposed solution to make the pages shorter would be to have one line
for each of these little work items. If you click the text in that one line,
it shows what had been a hidden div. If you click it again, it hides it.
See below:

I'm trying to check for this bug with the following script and it
*seems* to work. In IE it reports "bubbling" and in Firefox "not
bubbling" but I really have no direct way to confirm the Firefox
results until the bubbling bug is fixed.
Basically the test script assigns an onscroll event handler to a
textarea and then scrolls the textarea down then back up, checking to
see if a the event handler works (assigns the "bubbling" variable a
"true").
I had to code things with a few settimeouts otherwise Firefox, unlike
IE, wouldn't display the down then back up scrolling of the textarea.
Which may have been a problem.
Lacking a "debugged" Firefox browser, is there some further (indirect?)
tests and/or rational that would support or discredit this script as a
valid onscroll event check? ....

I have a javascript that manipulates the DOM with content that will be
of variable heights. How can I ascertain how high my div needs to be in
order to show all content without scroll bars. Rather than just having
this happen automatically, I want the div to expand with a DHTML
animation. So, I need to know where to tell the script to stop
expanding. In pseudo-code:
function divAni(){
if(this.height > 0){
if(this.height > 0){
this.height = this.height - increment;
}
setTimeout(divAni,delay)
} else {
if(this.height < this.height.needed){
this.height = this.height + increment
}
setTimeout(divAni,delay);
}
}
I'm just not sure how to ascertain how tall the div needs to be for the
content to display.

I know that iframes can be set to have scroll bars automatically apear when needed or put them there permanantly. However, I would like to have a Javascript slider on the topmost page scroll the iframe. It was possible to make a link on the topmost page change the content of the iframe by putting the iframe name in the link's target. Is this possible with a slider? I ask this because some of the content inside the iframe is on external pages so obviously we can't add the scroll bar there.

I have been trying to write a script that allows a user to click on a button like a plus sign to add an additional field for a phone number when they have more than one phone number to enter. I have created a script that sort of does this. It doubles up what is already there, so, the first time, everything is fine, but after that I get a lot more fields than I want. I am a php programmer and not familiar enough with javascript to get to what I want. My script is included below. What I am doing here is retrieving the html content and then adding it to what is already there. In php I would use an if conditional test to see if the data has been retrieved.
The first time it would retrieve the data into a variable. After that it would not retrieve it. I think I am getting into some scope and sequence issues here. Javascript is a bit different than php in these regards. Also there is a commented line in the code that asks another question about the use of variables that I don't understand. I also tried using appendChild() here to no avail. I couldn't get that to work at all.

I've added file upload support to the form plugin and I could use some help testing it out.If this feature interests you then go ahead and grab the beta plugin at:URL...File upload support is baked right into the plugin and there are no external dependencies.The plugin will automatically detect file input elements and use an iframe to submit the form if there are files to be uploaded.No extra coding or metadata is needed to take advantage of this new feature.In addition, even though an iframe is used instead of the XHR object, callbacks and global triggers still work as expected (so any code that you have in place to display activity indicators or blocking elements will still work).However, there are some challenges when using iframes in this manner.For one, it is quite difficult to determine if the submit operation succeeded or failed.The iframe becomes the target of the submit operation and so that is where the server response is written.The form plugin does its best to determine the data type (html, xml, etc),but the status is always 'success' unless an exception is caught during the type determination.URL...
If you use this page for testing *please* be kind to my server and only upload small files! I'd really prefer that you download the plugin and integrate it into your own test environment if possible.I've done some testing on FF, IE and Opera and the results are encouraging. I don't have access to Safari so I'm sure there are issues lurking for that platform.If you're interested in the code you can find it all tucked into the end of the ajaxSubmit method in a function called "fileUpload".

I'm having some real difficulty figuring out how to manipulate xml data with jquery. Here is my situation. I have a hidden TextArea that contains xml data, something like this:
<items>
<item value='1' text='x'></item>
<item value='2' text='y'></item>
</items>
So, let's say I want to remove the item with value='1'.
1) I grab the value of the textarea:
var xml = $("#" + id).val();
2) I then find the node and remove it:
$(xml).find("item[value='123']").remove();
Problem is, it doesn't remove anything! It finds the node just fine,but the remove() function doesn't seem like it is doing anything. I've tried looping through eacy item $('item',xml).each(function.... ); and
then calling remove(); but that does not work either.

I'm adding and removing SVG images in and out of a Parent SVG and I need to implement a scroll like effect on the new images after they are imported. They consist of text that I've word wrapped on the server. The images are imported through xmlrpc calls "getURL" with a function to delete the previous info and add the new info. After which it has a set of group tags with the new svg embeded between them. My hope is there is a way to manipulate the viewBox attributes but I don't know how to extract the 4 attributes of viewBox as separated integer values. I thought svgDocument.getElementById('detail').getAttribute('viewBox') would do it for me but I get a string of characters. Does anyone know how to get all four attributes as separated numerical values?

I was wondering if I could get some assistance with something that is probably easy for even an amateur javascript coder, but, I just can't seem to get after trying every iteration of code I can imagine.The deal is, is that I'm trying to put together a PHP search form, with checkboxes for countries (USA, CAN, MEX), and a set of checkboxes for each state in each country, including an "ALL STATES" checkbox for each country.I'm trying to input form controls where, if someone checks the "ALL STATES" box for any country, it will automatically uncheck any state checkboxes for that country. However, since the checkbox name attributes need to go to PHP as an array, I can't remove the square brackets in the name (I tried escaping the characters with up to 2 backslashes, but that didn't help).When I tried referring to the checkboxes via getElementById, that also failed. My code for the script as well as the form (abbreviated for convenience and sanity's sake) is below.
<script language="JavaScript">
<!-- Begin
function Check()

I have a form with a file upload field. When you hit submit the file should be manipulated by the client browser and not sent to the server (!). This is important. No file transfer to the Server. After the manipulation the file should be presented as download-able to the client. Which means it is stored from the browser to the client filesystem.
I do not know if any JavaScript Framework is capable of doing this.?
