This will replace only first occurrence.

I want to remove * from my text. I can not use str.replace(/blue/g, "red");

You can use RegExp("YourChar", "g") e.g.

var txt = document.getElementById('sometextbox').value;
var rechar = document.getElementById('replaceCharTextbox').value;
var srchChar = document.getElementById('searchCharTextbox').value;
var regx = new RegExp(srchChar, "g");
txt = txt.replace(regx, rechar);

I want to remove * from my string. Cannot use regular expressions. When i use like str.replace(/*/g, "red"); to remove *.
Code is getting commented. ( Javascript '/*' means comment the code)

use /\*/g as your search pattern.

Use regex like this:

XML

<script>
var s = "dfaskfjkd  d a";
s = s.replace(/[a]+/g, '');
alert(s);
</script>

which will remove all character 'a' in the string.
