页面加载后，我无法执行从控制台访问属性的Javascript函数

Question

I have a page that loads a bunch of scripts to prepopulate dropdowns and has scripts within the html onclick events and etc.

After the page loads and I open the page in the script console I can't do anything. everything is null and functions non-existent.

For example there is an onClick function onclick="Popup('Seattle');" .

If I try to invoke that from the script console I get Object Expected error like it doesn't even exist. But if I click the button the method fires right up. I can't modify this code so it's important that I get this functions going.

While I'm stepping through the code and have the script paused I have access to everything but as soon as it's finished it's back to nothing at all.

Anyone know what's going on and is there a way to invoke these functions?

Answer 1

"Object expected" sounds like for example the Popup function wants to be called like Popup.call(somedomnode, args...) . When called from an event handler, this is set to the element the handler is called on. If you just try to call it without some object as this , it might complain.

Otherwise probably the functions you want to call are not in scope at top-level. You don't really tell us how these functions are defined or how the event handlers get set up, so it's hard to say more where the problem might be.
