如何在功能中找到关键词？

Question

Thanks for your help first!

I have some jscripts like:

var id="001";

var name="Jerry";
...

function f1() {
  ...
  var qid="q1";
  ...
}

...
var qid="aaabbb";
...

function f2(){
  ...
  var myid="q1";
  ...
}

...

I want to use regular expression to get the names of function that contains key word "q1". Is there a simple way to do so?

Answer 1

Functions can be defined within other functions in JavaScript, so using regular expressions to try to solve this problem is impossible. Sorry :-(

Also, the problem is underspecified. What function name do you want in a case like this?

function outerFunction(x, y) {
    var innerFunction = function(z) {
        return {
            firstProperty: function() {
                return "q1";
            }
        };
    };
}

See? Three different ways to declare a function. How would you create a solution general enough to know the "correct" (most relevant) function name for cases like this?
