Change Color With CSS Class Instead Of Html Font Tags

Oct 5, 2010

I'm using javascript to change the color of certain words in an html document. Right now it uses <font> to make the change. I would like to use a CSS class named "alert" from an external style sheet to make the change. I've tried multiple things but no luck (className="alert", setClassName="alert" )
What is the correct way to replace the font part with a CSS class? Here is the working script:

<script type = "text/javascript">
window.onload = function (){
var text = document.getElementsByTagName('body')[0].innerHTML;
text = text.replace(/disabled/gi, "<font color=red>Disabled</font>" );
text = text.replace(/locked/gi, "<font color=red>Locked</font>" );
document.getElementsByTagName('body')[0].innerHTML = text;
}
</script>

Dynamically Change The Font Family Of The Loaded Html Page Of The Main Page?

Nov 4, 2010

On my webpage, I dynamically create an iFrame when a button is pressed, then load a html page from within my own domain into the iframe, based on what html page is loaded into a variable. My question is, can I dynamically change the font family of the loaded html page from the javascript of the main page? My code to create the iframe is:

function setSubTxt(){
var par = document.getElementById('parentDiv');
par.innerHTML = '<iframe src="'+subTxt+'" style="width: 375px; position: fixed; height: 365px; left: 400px; top: 145px; border=none;" name="subIframe" frameBorder=0></iframe>';
frames['subIframe'].window.location=subTxt;
document.subIframe.document.body.style.fontFamily = "Arial";
[Code]....

the variable "subTxt" has the url of the html page to be loaded (always on the same domain). The code: document.subIframe.document.body.style.fontFamily = "Arial"; was my attempt to dynamically change the font, but it didn't work. Also, it should be noted that there is no font family set in the html pages which would override this.

How To Change Contents Of Form Without Refreshing HTML Page

Jan 27, 2011

How do you update the contents of a form from a click of a button? I can poplate the contents of a table that is inside a form on the initial creation of the page

<form id="form1" name="form1" method="post" action="">
<p align="center">
List of Dying Patients
</p> <br><br>
<table border="1" align="center">
<tr>
<td>Last Name</td>
<td>First Name</td>
<td>Middle Initial</td>
<td>Date of Birth</td>
<td>SS Number</td>
<td>Marital Status</td>
<td>Gender</td>
</tr>
<script>
populatePatientsList();
</script>
</table>
</form>

and this is the contents of the function populatePatientList();
for (var x=0;x<mainArr.length;x++) {
document.write("<tr>" +
"<td>" + mainArr[x][0] + "</td>" +
"<td>" + mainArr[x][1] + "</td>" +
"<td>" + mainArr[x][2] + "</td>" +
"<td>" + mainArr[x][3] + "</td>" +
"<td>" + mainArr[x][4] + "</td>" +
"<td>" + mainArr[x][5] + "</td>" +
"<td>" + mainArr[x][6] + "</td>" +
"</tr>");
}

After this the table will have all the contents of the array. How do I reinvoke the form to have the updated version of the array shown on the table without refreshing the whole page? The page cannot be refreshed because the data is just in an array and when I do refresh the page the contents of the array gets back to its default. Is it even possible to refresh just a part of a page, in my case a table after a button click or are there other button events I can try to play with?

Using JS To Change Css Class?

Nov 13, 2010

I have a form with a list of things. The number of things in the list is variable, depending on certain factor, different things, different numbers of things. Next to each thing is a radio button.

There is a question with two radio buttons, "yes" and "no".

When "no" is selected, I want the radio buttons to be disabled, and the color of the text to change to gray.

For the radio buttons, I have a simple JS function:

javascript Code:

function enableCFFID()
{
document.cartform.cffid.disabled=false;
}

[Code].....

For the test that goes with each thing, obviously I don't want to have to assign unique ID (perhaps in a span tag that encloses the text). I would want a common name for all of them.

But this would mean I can't use getElementById.

What other method can I use to change the class for a group of span tags who's number is variable?

Converting HTML <a> Tag - Add The Class To It

Jun 21, 2010

<a href="www.mylink.com" class="myclass">click</a>

and I wanna change it to a javascript function that can be called via the SAME tag, but with this link:

[Code]...

this works to the point where it only opens the link, but now i can't figure out how to add the class to it. I tried adding it inside the body tag, but it doesn't work. So, I'm wondering if it's possible to set the class in the javascript.

Change Class Of LI OnMouseover?

Jan 25, 2009

I've been going out of my mind trying to get this to work, and now I'm out of time! It seems like it *SHOULD* be simple! All I am trying to do is get all of the <li> items that belong to a particular UL ID, and change the class name onmouseover. I've cut down the code to bare-bones to try and isolate the problem. I can get it to work if I use unique IDS for each list element, but that seems silly. The latest piece of code I am working with:

<script type="text/javascript">
var mylist=document.getElementById("mylist")
for (i=0; i<mylist.childNodes.length; i++){
if (mylist.childNodes[i].nodeName=="LI") {
mylist.onmouseover=function() {

Jun 9, 2011

This is probably really simple but I cant seem to figure it out.

Code:
<div id="imgcontainer" class="imgcontainer">
<img onclick="makeActive(1)" class="active" src="images/demo_01.gif" alt="testimonial" />
<img onclick="makeActive(2)" src="images/demo_02.gif" alt="testimonial" />

When an image is clicked it should:

1) clear the classes of all of the images

2) assign the clicked image a class of "active"

3) I then want to show a corresponding text (which would be in the same function.

Change Class Of Row, Clear Other Ones

Mar 9, 2010

I have a table that looks like so:

Code:
<tr id="calendarClick" class="chart_grey">
<td width="100" height="50">
<div class="calendar-categories_blue">7:30am</div>

[Code]....

When I hover over a row it changes to the color I am after just fine but I want it so that if I click a row, it stays that hover color.

Is thre an easy way to accomplish this using JS on it's own or even Jquery? So if I click on a table row, it is set to the same color as the hover state. if I click on another row, it removes the old one and highlights a new one?

Change GetElementById To Class?

how to change getElementById to a 'class' equivalent? This script works, however, I need to use it 3 times on a page but it uses ID instead of class. The two IDs that I wrap around the images that would scroll are: #marqueecontainer and #vmarquee.

I tried getElementByClass but it doesn't work.

Code:
#marqueecontainer{
position: relative;
width: 270px; /*marquee width */
height: 730px; /*marquee height */

Change CSS Class Property Using Javascript?

I have several tags on a webpage of the same class. If the user clicks a
specific checkbox I'd like to be able to alter the display property of the

This is an intranet application so we know that javascript will be enabled
and the browser will be IE.

How can I affect all the members of this class? Is there a way I can toggle
the DISPLAY property of a class so all the elements using that class would
be affected? Code:
