The front-end js reported an error Maximum call stack size exceeded.

The reason I encountered this problem is that when passing the value, there is a value that is undefined, which causes the call to continue, and the stack overflows.

The following is a reference in Ajax. The

solution is to write the value obtained from the input box above. After searching for a long time, another reason is that your page references js conflicts. You quoted the same file in the place where js is referenced globally, and haven’t encountered other scenarios yet.
