javascript - What's the Jquery equivalent of this

Question

How do I write this in clean jquery

document.GetElementById('A').innerHTML+=str;

Answer 1

Use append() if you just want to add more contents to the container element without changing the existing elements.

$('#A').append(str)

Note: See my comment to VisioN's answer below

Answer 2

Another way using .html() method:

$('#A').html(function(i, html) {
    return html + str;
});

Answer 3

if you want to add some text in innerHTML then Arun's answer is right if you wish to get innerHTML then you can use

$('#A').html()

Answer 4

This is enough.

$("#A").append(str);
