Description
- Prism version: 1.29
- Plugins: none
- Environment:
<WebBrowser>control used by .NET XAML WPF C# (Internet Explorer). Compatibility meta tags were set to:
Problem:
prism.js code is crashing with "Syntax error in regular expression" on line 209:
element.className = element.className.replace(RegExp(lang, 'gi'), '');
Solution:
Replace line 24:
From: var lang = /(?:^|\s)lang(?:uage)?-([\w-]+)(?=\s|$)/i;
To: var lang = /(?:^|\s)lang(?:uage)?-([\w-]+)(?=\s|$)/ig;
Replace line 209:
From: element.className = element.className.replace(RegExp(lang, 'gi'), '');
To: element.className = element.className.replace(lang, '');
This should work in Internet Explorer engine still used by modern C# controls as well as other browsers.
