Uncaught SyntaxError : Unexpected token ;

Question

I am getting Uncaught SyntaxError: Unexpected token ; at THE LINE NUMBER

    // HTML Helper
    var documentHtml = function(html){
            


        

Answer 1

Try to change:

.replace(/</(html|head|body|title|meta|script)>/gi,'</div>')

to:

.replace(/<\/(html|head|body|title|meta|script)>/gi,'<\/div>')

You need to escape / with \ in Javascript

Answer 2

The problem is:

/</(html|head|body|title|meta|script)>/gi

At the time of writing, SO's highlighting shows the problem with the original: the regex seems to be /</.

It should be:

/<\/(html|head|body|title|meta|script)>/gi

Since Javascript uses forward slashes to delimit regexes, you have to escape any forward slash inside it with a backslash.

IMO, using forward slashes for regexes was the most unfortunate syntax decision of JavaScript:

1. Parsing JavaScript is difficult because of / starting multiline comments, single line comments, division, and regexes. (Sublime, my editor choice, gets it wrong. Dreamweaver gets it wrong.)

2. It makes regexes for URIs/URLs particularly ugly.
