Answer 1

You can use built-in HTML parsing to do this. Append your text to an empty div, then use jQuery's .text() function to get the text in the div.

Here's a runnable snippet:

var text ='<!-- FieldName="Title" FieldInternalName="Title" FieldType="SPFieldText" -->Test Project';
var newText = $("<div/>").append(text).text();
alert(newText);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

This is just basic Regex. Here some documentation, and an example.

• Regular Expressions
• String.prototype.replace()

http://jsbin.com/wezozejusu/1/edit?js,console

var text = '<!-- FieldName="Title" FieldInternalName="Title" FieldType="SPFieldText" --> Test Project';

var after = text.replace(/<!--(.*)-->[\s]*/g, '');
console.log(after);
