Using JS with forms

TravisMath · 03-18-2005, 10:20 PM

Is there a way to get only part of an input value?
For example I have a file input and I need to only get the last part of it.

For example if they enter:

C:\Documents and Settings\Mike McDonald\My Documents\My Pictures\708d8b3face5f11b2acd82f5f6bbbd7e5295815.JPG

can I have the variable set to the thing after the last "\" mark. For instance in the above file place. could I have the variable set to 708d8b3face5f11b2acd82f5f6bbbd7e5295815.JPG

If so could you provide me with a code or a place to search for a code like this.

Thank You Very Much!

You could use the split function to return the last part of the string:

PHP Code:


			
<html>

<head>

<script type="text/javascript">

function parts()

{

    var path = document.forms[0].path.value;

    var parts = path.split("\\");

    var i = parts.length - 1;

    alert(parts[i]);



}

</script>

</head>

<body>

<form action="" method="">

<input type="text" name="path"><br>

<input type="button" name="but" value="Split" onclick="parts();">

</form>

</body>

</html>

Good luck;
