如何触发点击页面加载？ [英] How to trigger click on page load?

问题描述

我正在寻找一种在页面加载时自动点击某个项目的方法。

I'm looking for a way to automatically "click" an item when the page loads.

我尝试过使用

$("document").ready(function() {
    $("ul.galleria li:first-child img").trigger('click');
});

但它似乎不起作用？但是，当我输入 $（ul.galleria li：first-child img）。触发（'click'）; 进入Firebug的控制台并运行脚本时，它可以工作。

but it doesn't seem to work? However, when I enter $("ul.galleria li:first-child img").trigger('click'); into Firebug's console and run the script, it works.

可以在加载时使用触发事件吗？

Can the trigger event be used on load?

推荐答案

您尝试触发的单击处理程序很可能也通过 $（document）.ready（）附加。可能发生的是您在附加处理程序之前触发事件。解决方案是使用 setTimeout ：

The click handler that you are trying to trigger is most likely also attached via $(document).ready(). What is probably happening is that you are triggering the event before the handler is attached. The solution is to use setTimeout:

$("document").ready(function() {
    setTimeout(function() {
        $("ul.galleria li:first-child img").trigger('click');
    },10);
});

延迟10ms将导致函数在所有 $之后立即运行（文件）.ready（）已经调用了处理程序。

A delay of 10ms will cause the function to run immediately after all the $(document).ready() handlers have been called.
