使用.trigger（'resize'）时将参数传递给$（window）.on（'resize'） [英] Passing parameters to $(window).on('resize') when using .trigger('resize')

问题描述

S / O！

我需要一种可靠的方法来检测 $（窗口）.on（'resize'）已被用户互动或jQuery .trigger 电话解雇。

I need a reliable way to detect if $(window).on('resize') has been fired by user interaction or by a jQuery .trigger call.

我试过了以下，但我似乎没有在函数调用中返回参数：

I've tried the following, but I don't seem to get the parameters back in the function call:

$(window).trigger('resize',[true]);

function prepareOnResize(e, triggered){ console.dir(triggered); }
$(window).on('resize',prepareOnResize);

触发似乎返回屏幕的宽度，所以我尝试了以下，也无济于事：

Triggered seems to return the width of the screen, so I tried the following, also to no avail:

$(window).trigger('resize',[true]);

function prepareOnResize(e, width, height, triggered){ console.dir(triggered); }
$(window).on('resize',prepareOnResize);

在该实例中，触发返回 undefined 。

In that instance triggered comes back undefined.

我在这里不知所措 - 任何帮助都将不胜感激。谢谢！

I'm at a loss here -- any help would be greatly appreciated. Thanks!

推荐答案

jQuery在事件对象中放置一个属性 isTrigger ，您可以测试：

jQuery puts a property isTrigger in the event object, which you can test:

function prepareOnResize(e){ 
    if (e.isTrigger) {
        console.log('resize via jQuery trigger');
    } else {
        console.log('resize by user');
    } 
}

或者您可以使用 e .originalEvent ，jQuery只有本机事件对象才有，如上所述这里：

Alternatively you can use e.originalEvent, which jQuery only the native event object has, as mentioned here:

function prepareOnResize(e){ 
    if (!e.originalEvent)
        console.log('resize via jQuery trigger');
    } else {
        console.log('resize by user');
    } 
}
