Javascript Filtering Metacharacters Help

Hi Guys,

I would like to have a script where users can not type in any metacharacters such as <>$%& in my form input. How do I go about doing this?

So, far this is all I have is a function call, but how would I execute the script?

Thanks ahead. ?

function RemoveBad(InStr){
InStr = InStr.replace(/</g,””);
InStr = InStr.replace(/>/g,””);
InStr = InStr.replace(/”/g,””);
InStr = InStr.replace(/’/g,””);
InStr = InStr.replace(/%/g,””);
InStr = InStr.replace(/;/g,””);
InStr = InStr.replace(/(/g,””);
InStr = InStr.replace(/)/g,””);
InStr = InStr.replace(/&/g,””);
InStr = InStr.replace(/+/g,””);
return InStr;
}
