问题描述



我有这个重载功能

  SN.Reload =函数(设置){

var _timer = null;
var $ grid = null;

var init = function(){

$ grid = $(settings.wrapperSelector);

if(_timer> 0 || _timer!= null)
_timer = settings.timer;
else
_timer = 600000;

window.setInterval(function(){

LoadData();

},_timer);

};
$ b $ var LoadData = function(){

$ .ajax({
url:'/data.json',
类型:'GET' ,
dataType:'json',
cache:false,
成功:UpdateData,
错误:DataErrorHandler
});

};



$ b $ p
$ b

在正常状态下,它将在X分钟运行LoadData函数 -



我现在有另一个命名函数

  SN.CreateJsonFromDate = function(settings){

....

var SuccessLoad = function(){

_dateLoader.hide();
_wrapper.slideUp();


$ b}
}

是否可以使用SN.Reload中的LoadData在SN.CreateJsonFromDate中的SuccessLoad函数中?

LoadData函数在成功时调用UpdateData并从json数据更新HTML,我想在SN.CreateJsonFromDate中再次调用此函数,因为这会生成一个新的json文件。

解决方案

不,因为 LoadData SN.Reload



如果您想重新使用 LoadData 函数,不要将它的范围限制在 SN.Reload 中,而是可能(取决于你想要的),将它作为 SN.LoadData


I have run into a problem with a named function in Javascript.

I have this reload function

   SN.Reload = function(settings) {

        var _timer = null;
        var $grid = null;

        var init = function () {

            $grid = $(settings.wrapperSelector);

            if (_timer > 0 || _timer != null)
                _timer = settings.timer;
            else
                _timer = 600000;

            window.setInterval(function () {

                LoadData();

            }, _timer);

        };

        var LoadData = function () {

            $.ajax({
                url: '/data.json',
                type: 'GET',
                dataType: 'json',
                cache: false,
                success: UpdateData,
                error: DataErrorHandler
            });

        };
}

In the normal state this will run LoadData function at X minutes - this works as intended.

I now have another named function

SN.CreateJsonFromDate = function (settings) {

 .... 

  var SuccessLoad = function () {

        _dateLoader.hide();
        _wrapper.slideUp();



    }
}

Is it possible to use LoadData from SN.Reload Inside the SuccessLoad function in SN.CreateJsonFromDate ?

The LoadData function call UpdateData on success an updates the HTML from the json data and I want to call this function again in SN.CreateJsonFromDate as this will generate a new json file.

解决方案

No, because simply LoadData does not exist outside the scope of SN.Reload

If you do want to re-use the LoadData function, do not restrict it's scope to being inside SN.Reload and instead, perhaps (depending on what you want), attach it to the namespace as SN.LoadData
