How to display double quotes in JavaScript

Question

On html page if I give name in double quotes then it is not getting reflected on page. It displays a blank string. I tried with escape() function but that didn't work. So what is the way to display a string in double quotes.

One thing I forgot to mention that I want to display the string in input text box.

Answer 1

Hello everyone thanks for suggestions. My issue has been solved now. I created one private method to which I passed my required parameters which contains double quotes in it. Here is the method.

 HTMLEncode:function(str){
              var i = str.length,
                  aRet = [];

              while (i--) {
                var iC = str[i].charCodeAt();
                if (iC < 65 || iC > 127 || (iC>90 && iC<97)) {
                  aRet[i] = '&#'+iC+';';
                } else {
                  aRet[i] = str[i];
                }
               }
              return aRet.join('');    
            },

The above method will convert double quote into the required format to display it on web page. I referred one of the stackoverflow page for this. Thanks. Hope this will help others.

You have several options:

var str = 'My "String"'; //use single quotes for your string
var str = "My \"String\""; //escape your doublequotes
var str = "My "String""; //use it as html special chars

Answer 3

to show double quote you can simple use escape character("\") to show it.

alert("\"Hello\"");

Answer 4

Try escaping it either with \" or, if this does not work, with \x22

Oh, and if you want to output HTML instead of using this inside a Javascript string, use "

Answer 5

Whoever is still looking into this should use the following:

In your HTML page/template, use this code (in this case, he wants it for an input)

<input id="name" name="label" type="text" value="<%- label %>"

Notice that I'm using

<%- %>

instead of the classic

<%= =>

That should automatically escape the value you're trying to display and show up in your input without any extra work.
