Question

I have a function for removing extra or special chars:

function escapeHtml(unsafe) {
return unsafe
     .replace(/\r?\n|\r/g, "")
     .replace(/(\r\n|\n|\r)/gm," ")
     .replace(/\s+/g," ")
     .replace(/&/g, "&")
     .replace(/</g, "&lt;")
     .replace(/>/g, "&gt;")
     .replace(/"/g, "&quot;")
     .replace(/'/g, "&#039;")
     .replace(/!/g, "");
   }

While I am calling it and this part of my code looks like:

$(".product_json", data).each(function(){
    var thisH = $(this).html();
    var myNewString = eval( '('+ thisH +')');
    var toBeEscaped = myNewString.item_description;
    var escapedString = escapeHtml(toBeEscaped);
    myNewString.item_description = escapedString;
    myNewString = JSON.stringify(myNewString);
        console.log(myNewString);
//product_json.push( jQuery.parseJSON( myNewString ) );
});

But some how it says in console: SyntaxError: unterminated string literal

Data in this field looks like

VINOVO - Lotti TERRENO Hobbystico - Campestre!!! <br />

Answer 1

You assign a value to thisH in this line:

var thisH = $(this).html();

And then running it through eval() (surrounded by parentheses) in this line:

var myNewString = eval( '('+ thisH +')'); 

Use a debugger to check the value of thisH when the SyntaxError is triggered. Is it valid JavaScript when surrounded by parentheses? If not, that’s your problem.
