Just a little tip for the first answer. 只是第一个答案的小提示。 If your function is already defined, reference the function but don't call it!!! 如果您的函数已经定义，请引用该函数但不要调用它！！！ So don't put any parentheses after the function name. 因此，请勿在函数名称后加上任何括号。 Just like: 就像：

my_function(){};setInterval(my_function,10000);

You don't need jquery for this, in plain javascript, the following will work! 您不需要为此使用纯JavaScript的jquery，以下方法将起作用！

window.setInterval(function(){  /// call your function here}, 5000);

To stop the loop you can use 要停止循环，您可以使用

clearInterval()

you could register an interval on the page using setInterval, ie: 您可以使用setInterval在页面上注册间隔，即：

setInterval(function(){     //code goes here that will be run every 5 seconds.    }, 5000);

#6楼

The functions mentioned above execute no matter if it has completed in previous invocation or not, this one runs after every x seconds once the execution is complete 上面提到的函数无论是否在先前的调用中完成都将执行，一旦执行完成，此函数将每隔x秒运行一次

// IIFE(function runForever(){  // Do something here  setTimeout(runForever, 5000)})()// Regular function with argumentsfunction someFunction(file, directory){  // Do something here  setTimeout(someFunction, 5000, file, directory)  // YES, setTimeout passes any extra args to  // function being called}
