Board index » javascript » a way to run through scripts on entire document?

2005-04-13 01:25:13 PM
what you see below is the code, which is two parts, a highlight part,
and an unhighlight part. Below that is a sample of its use. What I am
trying to do, is have some sort of javascript, or onload command in the
body tag which will go through all of the 20-30 different <div>tags,
and check the settings of each of those radio boxes. Why? because I am
having the data editable in a form. Is there anyway to have say, a
script click each radio box/input box that has been selected or typed
in?
here is the javascript code...
function highlight(control) {var colour, div;
if(control.value) {colour = '#f3f3f3';}
else {colour = '#ffffff';}
if((div = control.parentNode) && div.style) {
div.style.backgroundColor = colour;
}
}
function unhighlight(control) {var colour, div;
if(control.value) {colour = '#ffffff';}
else {colour = '#f3f3f3';}
if((div = control.parentNode) && div.style) {
div.style.backgroundColor = colour;
}
}
<div class=divn id=dv23>
Do you know javascript?
<input type=radio name=disc value=NULL onclick="unhighlight(this);">
No Answer
<input type=radio name=disc value=0 onclick="highlight(this);">Yes
<input type=radio name=disc value=1 onclick="highlight(this);">No
<br>
Details: <br><textarea name=discd cols=60 rows=3></textarea>
</div>
