Encode HTML entities

问题

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

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());
