JS error Object doesn ' t support the reason analysis _javascript technique

JS Error:
Object doesn ' t support this property or method
Problem Reason:
The 1:JS code uses JavaScript keywords
2: The method name conflicts with the form or div form name
There are name= "submit" in 3.button
4. When uploading picture prompts: Object doesn ' t support this property or method
Cause: The version of AspJpeg installed on the server is less than 1.4.
Workaround: Install 1.4 or more versions of the AspJpeg component.

I also encountered this problem, then found:

Copy Code code as follows:

function Tfybxmoneytotalcheck ()
{
........
var tfybxmoneytotalcheck=0
}

The name of a function is the same as a name defined by Var. So it's wrong to quote.
