Javascript: document.getElementById() returns NULL

由 浪尽此生 提交于 2019-11-30 11:57:53
I am quite new with Javascript and I got a problem with document.getElementById() that always returns NULL, and that's driving me nuts. I have a element in my code and I want to get its coordinates so I can move it. Here is the code: <html> <head> <script type="text/javascript" > function MoveIt(obj) { alert(obj); // returns "Object HTMLDivElement" var xx = document.getElementById("arect"); if(document.getElementById("arect").value == null) { alert('NULL >> ' + xx.value); } else { alert('NOT NULL >>' + xx.value); } posX = xx.style.scrollTop; posY = xx.style.left; } </script> </head> <body

Difference between getElementById and jquery $('#smth')

由 女生的网名这么多〃 提交于 2019-11-30 06:54:21
问题 What's the difference between classic Javascript code: document.getElementById('theID') and the jQuery version: $('#theID') 回答1: document.getElementById returns a DOM object.

getElementsByClass and appendChild

由 徘徊边缘 提交于 2019-11-30 03:15:15
