ajax - How to escape & in a POST request in jQuery?

Question

i have an input element with & in value:

<input type="checkbox" value="Biografie, ?ivotopisy, osudy, Domácí rock&amp;pop" />

When i try sending it through an ajax request:

$.ajax({
    type: "POST",
    url: "/admin/kategorie/add/link.json",
    data: "id="+id+"&value="+value+"&type="+type,
    error: function(){alert('Chyba! Reloadněte prosím stránku.');}
});

the post data that actually gets sent is:

id: 1
pop:
type: e
value: Biografie, ?ivotopisy, osudy, Domácí rock

*Note that all the variables in data are defined and value contains $(thatInputElement).attr('value').

How can I escape the & properly so that post field value would contain Biografie, ?ivotopisy, osudy, Domácí rock&pop?

Answer 1

You can set your data option as an object and let jQuery do the encoding, like this:

$.ajax({
  type: "POST",
  url: "/admin/kategorie/add/link.json",
  data: { id: id, value: value, type: type },
  error: function(){ alert('Chyba! Reloadněte prosím stránku.'); }
});

You can encode each value using encodeURIComponent(), like this:

encodeURIComponent(value)

But the first option much simpler/shorter in most cases :)
