静态javascript变量用作Angularjs控制器中的计数器

我想创建一个静态javascript变量用作Angularjs控制器内的计数器.此静态变量将在重复调用的轮询函数中使用.

I would like to create a static javascript variable to be used as a counter inside a Angularjs controller. This static variable will be used inside a polling function that gets repeatedly called.

我想以这种方式使用静态变量；

I want to use the static variable in a manner that looks like this;

var polling_func = function() { static var counter = 0; if (counter == 10) { alert('Do action'); counter = 0; } counter = counter + 1; $timeout(polling_func, 1000); } polling_func();

不幸的是，我无法在javascript中使用static关键字声明静态变量.我应该如何在我的代码中这样做?

Unfortunately, I cannot declare a static variable using static keyword in javascript. How should I go about doing so in my code?

推荐答案

为什么不声明全局变量，因此无论何时调用函数，它都不会更改值.

Why not declare a global variable, so it will not change the value whenever function is called.

var counter = 0; var polling_func = function() { if (counter == 10) { alert('Do action'); counter = 0; } counter = counter + 1; } polling_func(); $timeout(polling_func, 1000);
