The JavaScript function has the same name overlay problem

In JavaScript scripts, local functions have the same name as the perimeter function, which overrides the out-of-network function, where variables can be defined repeatedly.

See the example below.

A =  function () {var me = This;me.method1 = function () {var items = [1,2,3,4,5];for (var i=0;i<items.length;i++) {if (1 {var items = [6,7,8];if (items.length = = 0) {alert (' Test is ok! ');} Alert (Items[i]);}}}

The local variables items are defined as follows:

var items = [5,6,7];

The definition of the extranet variable will be overwritten:

var items=[1,2,3,4,5];

Loops can only be performed 3 times.

The workaround is to use a different function name to avoid the same name as the function.
