Enabling Disabled Buttons in JS

DanielGibbs · Jun 12, 2004

Hi, I don't know javascript so here goes.

I've created a drop down menu and when a user selects a certain option and clicks the submit button a load of information is printed about the option (in PHP).

I have a disabled button called 'button' lol and I want it to be enabled when a user clicks a certain option in the drop downlist. I tried button.disabled=false as a random guess but as I said I don't know JS lol. Worth a try.

If you can help that'd be great!

Thanks! Dan G!bbs

Hmmm... You want it activated when what option is clicked?

on the <select> tag add this

onchange='window.open(this.value,"_self")'

on your options (<option>) you should set the value as the page you want to go to

Haha I suppose it's too late, but I played with this for a few minutes and got this.
Script:
function dis() {
var nah = document.frm.sel.value;
if(nah == "true"){ document.frm.lol.disabled = true; }
if(nah == "false"){ document.frm.lol.disabled = false; }
}

form:
<form name="frm">
<select name="sel" onChange="dis()">
<option> - </option>
<option value="false">Enable</option>
<option value="true">Disable</option>
</select>
<br /><br />
<input type="button" name="lol" value="Hello" onClick="alert('hello');">
</form>
