How to trigger click on page load?
提问by Justine
I'm looking for a way to automatically "click" an item when the page loads.
我正在寻找一种在页面加载时自动“单击”项目的方法。
I've tried using
我试过使用
$("document").ready(function() {
$("ul.galleria li:first-child img").trigger('click');
});
but it doesn't seem to work? However, when I enter $("ul.galleria li:first-child img").trigger('click');into Firebug's console and run the script, it works.
但它似乎不起作用？但是，当我进入$("ul.galleria li:first-child img").trigger('click');Firebug 的控制台并运行脚本时，它可以工作。
Can the trigger event be used on load?
可以在加载时使用触发事件吗？

The click handler that you are trying to trigger is most likely also attached via $(document).ready(). What is probably happening is that you are triggering the event before the handler is attached. The solution is to use setTimeout:
您尝试触发的点击处理程序很可能也通过$(document).ready(). 可能发生的情况是您在附加处理程序之前触发了事件。解决方案是使用setTimeout：
$("document").ready(function() {
setTimeout(function() {
$("ul.galleria li:first-child img").trigger('click');
},10);
});
A delay of 10ms will cause the function to run immediately after all the $(document).ready()handlers have been called.
10 毫秒的延迟将导致函数在所有$(document).ready()处理程序被调用后立即运行。

$(function(){
$(selector).click();
});

$("document").ready({
$("ul.galleria li:first-child img").click(function(){alert('i work click triggered'});
});
$("document").ready(function() {
$("ul.galleria li:first-child img").trigger('click');
});
just make sure the click handler is added prior to the trigger event in the call stack sequence.
只需确保在调用堆栈序列中的触发事件之前添加点击处理程序。
$("document").ready(function() {
$("ul.galleria li:first-child img").trigger('click');
});
$("document").ready({
$("ul.galleria li:first-child img").click(function(){alert('i fail click triggered'});
});
