javascript - 跨不同的 obj 属性设置 deferred/promise

Question

使用 jquery 1.6.*

我正在使用模块式模式。我希望能够在“UNI.obj1”中创建和解析延迟并能够使用它们，以便我可以在“UNI.obj2”对象中启动行为。

假设我有以下对象:

var UNI = {};

UNI.obj1 = function() {
    // set up a deferred here;

    var method1 = function(){
       // RESOLVE deferred here

    }
    var method1A = function(){
        window.onload = function(){ 
            method1(); 
        }
    }()
}()

UNI.obj2 = function(o) {
    var method2 = function(){
       // Use the PROMISE of the resolve here

    }
}(UNI.obj1);

定义您的延迟对象并返回它的 promise ，然后对其采取行动。

var UNI = {};

UNI.obj1 = function () {
    // set up a deferred here;
    var def = $.Deferred();

    var method1 = function () {
        // RESOLVE deferred here
        def.resolve();

        return def.promise();
    }
    var method1A = function () {
        window.onload = function () {
            method1();
        }
    }()
    return def.promise();
}

UNI.obj2 = function (o) {
    var method2 = function () {
        // Use the PROMISE of the resolve here
        o().done(function () {
            // it was resolved!
            console.log("Resolved!");
        });
    }()
}(UNI.obj1);
