Loop thru inputs
- Thread starter crabgrass
- Start date
Crab, this assumes only inputs with a type of 'text' will be set to readOnly. If already readonly it will remove this.
Cheers
Nick
where would we be without rhetorical questions...
Code:
function LoopyLoopTheInput()
{
var inputs = document.getElementsByTagName('input');
for(var i=0;i<=inputs.length;i++){
var input = inputs[i] ;
if(inputs[i].type== 'text'){
if(inputs[i].readOnly==true){
inputs[i].readOnly = false;
}
else
{
inputs[i].readOnly = true;
}
}
}
}Cheers

For some reason I can't identify I get an error when Clicking the button. It says "line 36 object expected." Can you see the problem?
Thanks again.

Well, I'm back from vacation and still working on this little routine. My test page now looks like this.

The alert will fire 4 times meaning that the inputs collection must include something besides the 2 textboxes and the button. (the form maybe?) Adding the if statement produces an error because the unknown extra input does not have a "type". Do you know what the unknown input is and how to deal with it?

The reason for 4 alerts:
[ol][li]<input type="text" name="txt1" class="noedit" value="" readonly>[/li]
[li]<input type="text" name="txt2" class="noedit" value="" readonly>[/li]
[li]<input type="button"
name="cmdEdit"
value="Edit"
style="width: 100px"
onclick="ClearReadOnly();">[/li]
[li]for (i=0;i<[!]=[/!]inputs.length;i++)[/li][/ol]
Buttons are still inputs (hence the <input> tag), so that is adding one that you're probably not expecting. Additionally, your loop is going from 0 to 3 (4 total loops). You probably meant to put i < inputs.length - you don't need the equals sign there.

OK, I've got it working. Here's my code.
<code>
function fnClearReadOnly(){
var inputs = document.getElementsByTagName("input");
var i=0 ;
for (i=0;i<inputs.length;i++){
if (inputs.type=="text"){
inputs.readOnly = false ;
inputs.className = "" ;
}
}
}
</code>
I will eventually need to enable/disable <textareas> and <selects> also. The IF will need to be a little different for these. Can you point me in the right direction?
Thx
