How can I dynamically change the color of values on a page, to show if they are above or below a target value entered in a text box on the page. Those below should be shown in green, those above in red, and identical (equal) should be in amber. Values can be put in a particular tag and then use the getElementsByTagName.

I'm having a problem dynamically changing the color of a table background.
I'm not sure exactly how to word this, but I'll give an example.
I have a function called greentored(propname)
i want to be able to change the following to a different color:
document.all.propname.style.visibility
but substitute the propname with the variable that I'm sending over.
Here is what I had written before but it did not work, it should be easy to
understand what i'm trying to do:
function greentored(propname) {
changecolor = "document.all." + propname + ".style.background";
changecolor = "green";
}
I understand why this doesn't work because all i'm doing is reasigning
"changecolor" to equal green, rather then setting the property of the first
instance of "changecolor" to green.
I am building an online survey using a survey creation tool which allows me to incorporate javascript for additional functionality. However, I am new to javascript so would appreciate any help that you could provide me with.
I have question types like agreement scales, where the respondent sees a list of statements and has to rate each one by clicking on a radio button. The source code of the matrix table looks like this:
[Code].....
This code works as intended; however, as you can see, it loops through all the radio buttons when one is clicked. Is there a way to accomplish this without looping through all the radios, and thus make the script run faster?
Also, I have read that the addEventListener function does not work for older versions of IE. Is there a simpler alternative?
I have a small script that changes the background color of my page from white to grey when the user clicks a button.at the moment it works fine accept for when the user tries to navigate to another page (on my website) after changing the background color.if a user changes the background color to grey and than tries to view another page, the background color becomes white again.is there any way to make the change only controlled by the button?my head code looks like this (at least the relevant parts):
View 8 Replies View RelatedI am currently successfully using the following code to randomly change the color of specified text ("quotations" - see below) each time the page is reloaded. The only problem is that the colors are too random. Instead of the code I now have, I'm looking for code that would allow me to define a distinct list of colors through which the text would randomly rotate each time the page loads. In other words, I want to choose each of the randomly loaded colors of my text.

So my functions are dealing with Time. The function delay_time() is called by clicking a button in html and the return value of the function is displayed in a textbox. What I need to do is basically if the value of resultingtime is greater that the value of delay time I need the value shown in red(ff0000) and bold and if it isnt then I need it displayed in bold green(00ff00). but Ive tried doing this in my javascript and found that I cant code it in there the way that I know. I think that I have to do it in the html coding but I dont know how.

View 1 Replies View RelatedSo I'm trying to change the background color of a textbox depending on how many characters are enter (putting it green/red depending on count), and I'm having a hell of a time. There are 50 different textbox IDs on the page (give or take, dynamically generated), each unique/sequentially numbered (id1, id2 ... id50).Now I'm not that good with Javascript, but this is what I can up with so far.I was trying to use 'this.id' so I wouldn't have to name each of the IDs.
View 2 Replies View RelatedI'm a member of a forum the for the Winter season has changed it's CSS a:link color attribute to a more winter themed colour. However I want to revert back to original as I don't particularly like the new colour.
My theory is to create a small JS file, that I can define Opera (my browser) to load when loading the site, which will change the colour of links back to the original colour. I have the colour code HTML I want to change it to.
I've only ever done a small amount of JS coding but from the research I've done it should go something like this,
document.style.alinkColor = "COLOR"
I got to that via discovering that
document.style.backgroundColor = "COLOR"
will change the background colour attribute, however it doesn't seem to work. I think my problem lies somewhere in the attribute name, I know the usually with JS CSS Attributes you would make the attribute starting with a lower case letter and the sub-attribute (e.g. the color bit) starting with an upper case.
I want to create a basic script where someone clicks the button and the document color is changing. while I can do it with inline even handlers and also using the script block in html document, i am not able to achieve the result using the external js.js. My goal is not to use any even handlers at all inside the html document. why the script I wrote is not working.

I'm having problems with changing the background color of a div when it is hovered over. So here is my code:
function changeColor(the_div_name)

var the_div, div_string;
if (document.all)

div_string = "window.document.all." + the_div_name + ".style";
the_div = eval(div_string);
} else if (document.layers) {
div_string = "window.document." + the_div_name;
the_div = eval(div_string);
} else {
alert("sorry, this only works in 4.0 browsers");
return;
}
the_div.background-color = "white";
}
here is my code for the html:
<div name="div7" style="background-color:black; color:blue; position:absolute; top:95; left:664">

I have two multiple select inputs. Initially the first contains a bunch of
items and the second is empty. Using a common method, I move items back and
forth by double clicking on them.
This portion works perfectly, but I would also like to change the background
color of the select element with the current focus. I have defined the following classes:
..selected {
background: #C0FFFF
}
..deselected {
background: #FFFFFF
}
Using the following function below I am able to shift the background color
of rows containing content, but the color of the empty rows remain the
"selected" color. How can this effect be achieved for all rows, whether they
contain content or not?
