JS error Uncaught TypeError: undefined is not a function, solved, uncaughttypeerror

Chrome debugging error: Uncaught TypeError: undefined is not a function. All data cannot be displayed.

The error message is as follows: an unspecified method is called. A null value actually calls a jq method, causing an error.

☆Solution: Before calling a method, check whether the value is null. If it is not empty, call the method. The reference code is as follows:

If (d! = "" & D. gblen ()> My. option. colModel [I]. len)
{
Hide + = 'relative ';
D = getdomaindata (d, My. option. colModel [I]. len, "more-msg-width ");
}
