Encode HTML entities [duplicate]

Question

I am parsing some data from feedburner of which contains HTML entities. I am trying to encode the HTML entities using jQuery as such:

var encodedStr = data['1']['result']['content']; // content with HTML entities
$("#content").html(encodedStr).text();

but with no results.

Here is what its parsed: http://jsbin.com/ihadam/1/edit

Do you want to interpret the <p> stuff as actual HTML tags when you insert it? — Barmar

@Barmar Yes. Check this: jsbin.com/ihadam/2/edit - I want it to be an actual image tag rather than a string. — jQuerybeast

I think this might do what you need: stackoverflow.com/questions/1219860/… stackoverflow.com/questions/10715801/… — user1664202

Basically you should encode your html entities into html as such:

var encodedStr = data['1']['result']['content'];
var a = $("#content").html(encodedStr).text();

Then get the encoded text and apply it as html() as such:

$("#content").html(a);

That should work.

You can save the bloat of JQuery with pure JavaScript functions.

Sometimes you just want to encode every character... This function replaces "everything except for nothing" in regxp.

function encode(e){return e.replace(/[^]/g,function(e){return"&#"+e.charCodeAt(0)+";"})}

function encode(w) {
  return w.replace(/[^]/g, function(w) {
    return "&#" + w.charCodeAt(0) + ";";
  });
}

test.value=encode(document.body.innerHTML.trim());
