.find() does not find elements

in Getting Started • 10 years ago

Hello Community,

I am new to jQuery and I came across a Problem with the find function.

I got the following two lines in my code

console.log($('ul.gallery'));
console.log($("ul.gallery").find("img"));

And the output in Opera Dragonfly looks like that

As you can see, the find function does not find the img tags, but as you can also see, it is there.

I don't know if this has something to do with that strange <::after> tag. And I don't know where this comes form. But I need a reference to that img tags. And can't get it.

Can you please help me?

Kind regards

Angelo Hannes

Most likely your opening and closing tags are not balanced!

No, that isn't it.

But I think I'm getting insane.. Or Opera Dragonfly does some black magic.

I tried the getElementsByTagName, like deepthi suggested, and Opera Dragonfly showd all img tags. But exactly one code line later, I loged the length of the nodelist and it prints 0 on the console.

WTF is going on?

And as if there is reale some bad trick that Dragonfly is playing to me..

What is the right way to inject elements in the DOM and select them later?

Kind regards

Have you tried it in another browser to see if it is a dragonfly thing or not?

Can you post the actual mark up here? Maybe there is something in your markup? There is a huge difference between getElementsByTagName and the selector you posted above. All that the getElements method does for you is verify that there are images, the selector is looking for images within a specific hierarchy.

console.log($("ul.gallery").find("img")); is not quite right... read about selectors here: http://api.jquery.com/button-selector/

Hello,

I think it was a Dragonfly thing. It showed elements in the console, which were not in the dom at the time of selection.. bug or feature? don't know, but something you should know..

thanks for your help
