js 顺序提交表单

1、js脚本队列实现

function SubmitTaskList() {
    var obj = {};
    var taskList = [];
    var index = 0;
    obj.AddTask = function (task) { if (task) taskList.push(task); }
    obj.Post = function () {
        if (index < taskList.length) {
            var task = taskList[index++];
            if (!task.Check()) {
                return;
            }
            task.onSuccess = function () { obj.Post() };
            task.Post();
        }
        else
            obj.Rest();
    }
    obj.Check = function () {
        for (var i = 0; i < taskList.length; i++) {
            task = taskList[0];
            if (!task.Check()) {
                return false;
            }
        }
        return true;
    }
    obj.Rest = function () { index = 0; }
    return obj;
}

执行对象

function SubmitTask(checkFun, postFun) {
    var obj = {};
    obj.Check = checkFun;
    obj.Post = function () {
        postFun(obj.onSuccess);
    }
    return obj;
}

2、使用

var taskList = SubmitTaskList(); 声明方法对象

taskList.AddTask(SubmitTask(Submit_Check, submitContactDifferInfo));添加执行队列

taskList.AddTask(SubmitTask(Submit_Check, function (onSuccess) {
                alert("保存成功");
                if (onSuccess) {
                    onSuccess();
                }
            }));

taskList.Post();
