Although PHP and JavaScript sometimes look similar, they use variables
differently in that JavaScript doesn't require variables to start with
a prefix ($ or @). Also the string replace function in JavaScript is
different from PHP. It takes the form of a method for the string
variable. like so: myString.replace(/searchforWithRegEx/,
'replacewith');
You'll want to change your function to use the proper syntax for
JavaScript before it can work.
function parseToHTML(strEncodedText)
{
var strDecodedText = strEncodedText.replace(/</g, '<');
strDecodedText = strDecodedText.replace(/>/g,'>');
strDecodedText = strDecodedText.replace(/"/g,'"');
strDecodedText = strDecodedText.replace(/'/g,'\'');
strDecodedText = strDecodedText.replace(/&/g,'&');
return strDecodedText;
}
Here is a good JavaScript resource for understanding how the basics
work:
