使用 javascript 确定 javascript 中的堆栈深度

ECMAscript supported for quite a while the Function.prototype.caller property. Even if its deprecated in ES5 strict, IE should still support it. So you could basically loop your way up through the involved functions.

function one() {
   two();
}

function two() {
   three();
}

function three() {
    var caller = three.caller;

    console.log('caller was: ', caller.name);

    while( caller = caller.caller ) {
           console.log('caller was: ', caller.name);
    }
}

(function outer() {
    one();
}());

这将输出:

caller was: two
caller was: one
caller was: _outer

因此，如果您知道错误发生在哪个函数中，那么您就可以从最初调用该方法的方式中得到答案.如果您只是在深度之后，您可以计算对 caller.caller 属性进行了多少次交互.至少 IE8 应该支持debugger"语句，您可以在该脚本中调用它来将调试器带到舞台上.
