Hi I have downloaded the code to allow special html characters in <textarea> be replaced with the actual code so it does not cause problem when the text is submitted into the database. For example ‘>’ to be replaced with ‘>’ So for a string ‘ 3 > 2’ I expect to be replaced with ‘3 > 2; in the text box. However it does not work.
I put in the alert statements and it shows that the js function is being invoked, but after the function is done, the special characters in the text box remain the same. Can someone help?
<html>
<header>
</header>
<body>
<script language=”javascript”>
function html2entities(){
var re=/[(<>”‘&]/g
for (i=0; i<arguments.length; i++)
alert(“check char”+ arguments[i].value);
arguments[i].value=arguments[i].value.replace(re, function(m){return replacechar(m)})
}
function replacechar(match){
if (match==”<“)
return “<”
else if (match==”>”)
return “>”
else if (match==”””)
return “"”
else if (match==”‘”)
return “‘”
else if (match==”&”)
return “&”
}
</script>
