I am fetching HTML string and I want to construct a jQuery object from it and then perform operations but I am getting undefined.

    var data = '<h1>Hi World</h1';
    var html = '<div id="rendered">'+data+'</div>';
    //var content = $($.parseHTML(html));
    var content = $.parseHTML(html);

    console.log($(content).find('#rendered').html()) // it says undefined

>Solution :

find() is used to look for child elements. #rendered is the parent node in the HTML structure you create, so find() doesn’t return anything. You need to use filter() instead as that includes the current node when searching.

Also note that $.parseHTML() isn’t required – jQuery does this automatically when you provide a HTML-formatted string to the jQuery object contructor.

var data = '<h1>Hi World</h1';
var html = '<div id="rendered">' + data + '</div>';

console.log($(html).filter('#rendered').html())
