Question

正如我看到的,我要把我的法典作为自我挑动的匿名职能散发。此外,根据我的守则,我必须监测另一个校准负荷,因此,我可以在可用时使用。

(function(window, document, undefined) {
  staffHappens();
  var initMyLib = function() {
    if (typeof(myLib) ==  undefined ) {
      setTimeout("initMyLib()", 50);
    } else {
      useMyLib();
    }
  }
  moreStaffHappens();
  initMyLib(); //-> initMyLib is undefined
})(this, document);

如何发生这一错误? InitMyLib是否属于封装(自发)功能的范围?

Answer 1

更改<代码>准时”(“initMyLib()”),50;至settimeout(initMyLib, 50);

当你提出论据时,它将试图在时间外出时加以评价,但时间范围将遍及全球。在全球范围不存在你的方法。

Answer 2

You could also use a real anonymous function to avoid scoping issues:

(function() {
    if(typeof(myLib) ==  undefined )
        setTimeout(arguments.callee, 50);
    else
        // loaded
})()

阅读对一些杂质的答复: 间歇时间范围

这是该答复中的代码样本:

/*
this will obviously crash... and all recursion is at risk of running out of call stack and breaking your page...

function recursion(c){
    c = c || 0;
    console.log(c++);
    recursion(c);
}
recursion();

*/

// add a setTimeout to reset the call stack and it will run "forever" without breaking your page!
// use chrome s heap snapshot tool to prove it to yourself.  :)

function recursion(c){
    setTimeout(function(c){
        c = c || 0;
        console.log(c++);
        recursion(c);
    },0,c);
}

recursion();

// another approach is to use event handlers, but that ultimately uses more code and more resources
