Hi,

First, there is a string called:

JavaScript

var bookPath = '../MyBook/Computer/Sample_1/Sample_1_p16.pdf';

And here is my regular expression:

JavaScript

bookPath = bookPath.replace( /Sample.+pdf/gi, "" );

Finally, the result of bookPath is "../MyBook/Computer/".
How do I get "../MyBook/Computer/Sample_1/" instead?

Many thanks~

Use this for an example:

XML

<html>
<head><title>Regular Expression Test</title>
<script type="text/javascript">
function Test (value) {
    alert(value.replace(/\w{2}\d{1,2}\.pdf/i, ""));
}
</script>
</head><body>
<form action="">
<input type="button" value="Test 1" onclick="Test('../MyBook/Computer/Sample_1/Sample_1_p16.pdf')">
</form>
</body></html>
