Concating the string to another string

I want to create a tag like <?xml version="1.0" encoding="UTF-8" standalone="no"?> on button click, so i have created a simple function to achieve this

function onclick(){
    var element = getStringBuilder();
    element.append("<?xml version=" + "1.0" + " encoding=" + "UTF-8" + " standalone=" + "no" + "?>");
    element = element.toString();
}

  function getStringBuilder () {

             var data = [];
             var counter = 0;

             return {
                 // adds string s to the stringbuilder

                 append: function (s) {
                     data[counter++] = s;
                     return this;
                 },
                toString: function (s) { return data.join(s || ""); }
        }
    }

But i am getting output as below

<?xml version=1.0 encoding=UTF-8 standalone=no?>, i want "1.0", "UTF-8", "no" as string in the tag. How can i achieve this

Thanks in advance

JavaScript uses " to separate the strings. Use ' and inside this, use ". Like this:

element.append('<?xml version="1.0" encoding="UTF-8" standalone="no" ?>');

In this case, just use different quotes:

element.append('<?xml version="1.0" encoding="UTF-8" standalone="no"?>');

In the more general case, escape:

element.append("<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>");

Either way, concatenating is not appropriate here.

What you're currently doing doesn't have any quotation marks within the string. "a" + "b" concatenates the strings containing the characters a and b together to make "ab", not "a""b".

The easiest way to do this is to wrap your entire string in single quotes (') and retain the double quotes (") within your string:

element.append('<?xml version="1.0" encoding="UTF-8" standalone="no"?>');

Another method is to escape your double quotes to make JavaScript treat them as part of the string:

element.append("<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>");

By actually including them in the string?

element.append('<?xml version="1.0" encoding="UTF-8" standalone="no"?>');
