Javascript: Replace all occurences in a string

Most of the people don't know how to replace all occurences in a string. We know the ordinary expression in javascript to replace matching string. that is string.replace() here is an example of this.

<script>
var i_str = '<html><head></head></html>';
var o_str = i_str.replace('<','<');
o_str = o_str.replace('>','>');
alert(o_str);
</script>

But output of this will be like this: <html><head></head></html> So, we have to Regular expression pattern to replace all occurences. Syntax is: string.replace(/string/g,replace) Here is an example:

<script>
var i_str = '<html><head></head></html>';
var o_str = i_str.replace(/</g,'<');

o_str = o_str.replace(/>/g, '>');
alert(o_str);
</script>

Now the output will be: <html><head> </head></html>
