How to check for HTMLDivElement in IE7

Question

I have the following code;

if(data.constructor == HTMLDivElement) 

Now IE7 does not have/support HTMLDivElement.

How do I check for the same for IE7.

I tried

if(HTMLDivElement != undefined) 

But it still gives an error on IE7.

Answer 1

尝试：

if(data.constructor === document.createElement('div').constructor)

Answer 2

Since you are using jQuery, you can use a simpler test.

$('div#id').length == 0

That would be true when the element did not exist.

Answer 3

You could simply do it using jQuery's .is() method:

var isItDiv = $(data).is('div');

jsFiddle Demo :

//Using plain DOM elements - no cheating
var e1 = document.getElementById('elem1'); //<div id="elem1">
var e2 = document.getElementById('elem2'); //<button id="elem2">

//it does not even have to be in the DOM!
var ce = document.createElement('div');

console.log($(e1).is('div')); //true
console.log($(e2).is('div')); //false
console.log($(ce).is('div')); //true

Answer 4

I did something a kind simple like this:

if (data.tagName == 'DIV') {
    // do something
}
