Javascript Regex IE8问题

Question

I have a div as defined below:

<div id="bookmark_error" class="text-error">Character '' is not allowed in bookmark name.</div>

By default it is hidden as defined below:

$("#bookmark_error").hide();

Some of characters are not allowed while saving bookmark on a page for eg < and >

Here a validation check that is performed at the time of bookmark save:

...
var bookmark_name = $("#bookmarks-form").find('input[type=text]').val();
var skipChars = ["<", ">", "&lt;", "&gt;", "&lt", "&gt", "&#60;", "&#62;", "&#60", "&#62"];
                for (var i=0; i < skipChars.length; i++){
                    var skipChar = skipChars[i];
                    while(bookmark_name.indexOf(skipChar) != -1){
                        $("#bookmark_error").html($("#bookmark_error").html().replace(/'[^]*'/g, "'"+skipChar+"'"));
                        $("#bookmark_error").show();
                        return;
                    }
                }
...

But its not working as expected in IE8 browser. Am I doing something wrong in javascript regex?

Here is some sample value-input-value:

value : Character '' is not allowed in bookmark name.

input : <

value : Character '<' is not allowed in bookmark name.

input : >

output : Character '>' is not allowed in bookmark name.

You need to add \\d in your regex for it to work on ie8

Reference from : RegEx not working in IE8

So your code will look like this

$("#bookmark_error").html($("#bookmark_error").html().replace(/'[^\d]*'/g, "'"+skipChar+"'"));
