Javascript encoding decoding problem

Question

I have the following javascript

 var cst = "\x26";
 var other = $("#D1").html();

And my html has D1 div like the following

 <div id="D1">\x26</div>

Now when I add a breakpoint and see my two variables cst and other. One is shown & and another \x26. Also

cst.length == 1

but

other.length == 4

I am confused. I need the value of other to be same (&) and I cannot change the Div. I am also using JQuery so I can use $(div_id)

HTML does not use Javascript-style escape strings.

Your <div> actually says \x26, not &.

Then how can I convert it back to & in Javascript again? I cannot change the Div and I need output as &

Try this.

var other = eval( "'" + $("#D1").html() + "'" );

Thanks. It works. But I am not in favor of eval. I will select this if I don't get any other working answer.

Use the text content (text() in jQuery) not innerHTML/html() which will have extra HTML-encoding applied. JSON.parse is safer then eval where available. You may want to check that there's no unescaped quote or newline in the string before evaling it otherwise.
