Enable and disable of text box through a checkboxWe may need to enable or disable a text box based on the input of the user by using disabled property of the element. For example we have some choices for the visitor and one of the options is Others. Once the visitor select the others options then ( only ) one text box will be enabled to allow the visitor to fill the details.
Here is the demo of this. Click the checkbox to enable or disable the text box.
We have used the body onload command to keep the text area disabled while the page is loading.
The full code is here.
<html>
<head>
<title>(Type a title for your page here)</title>
<script language="JavaScript">
<!--
function enable_text(status)
{
status=!status;
document.f1.other_text.disabled = status;
}
//-->
</script>
</head>
<body onload=enable_text(false);>
<form name=f1 method=post>
<input type="checkbox" name=others onclick="enable_text(this.checked)" >Others
<input type=text name=other_text>
</form>
</body>
</html>

| This works as described, but what if I want to have multiple disabled text fields linked to multiple checkboxes? The result for me is that checking ONE box enables ALL the text fields, but I would like it to only enable the one. Any ideas? Thanks! | | newbie | 02-08-2012 |
