Calling/Inserting functions before jQuery's document.ready

Question

I need to be able to insert or call a function before document.ready() is called in jQuery. I'm invoking the document.ready function from another file, which theoretically gives me control over when document.ready is called.

Source file (.js):

$(document).ready(function () {
    // some code...
});

Technically, however, as soon as I call the file with the document.ready(), it is immediately loaded, and I had no chance of finding something similar to a pre-condition to insert and call my function.

Test file (also a .js):

// this is a unit testing file, JsTestDriver style
TestFunction.prototype.testFunction = function() {
    // calls my function
    // then calls the document.ready function below
    $.readyList[1]();
}

Since I'm calling the document.ready function from a .js unit test file, the "script" tag does not work for me. I need to be able to call my functions before the DOM (or document.ready) gets called. Does anyone know the answer to this one?

Thanks.

Answer 1

在document.ready之前放置您希望在document.ready之前执行的代码。

Answer 2

Override the ready function.

var fn = $.fn;
var realReady = fn.ready;
fn.ready = function ready()
{
    console.log("Before ready.");
    var result = realReady.apply(this, arguments);
    console.log("After ready.");
    return result;
};
