Simulate a mouse-click in Javascript
提问by zyl1647
Looking for a Javascript that do a left-mouse click on a image/button identified by ID or CLASS name, wait x seconds and repeat. And able to run in developer tools Console tap, in chrome and firefox.
寻找在由 ID 或 CLASS 名称标识的图像/按钮上单击鼠标左键的 Javascript，等待 x 秒并重复。并且能够在开发者工具 Console tap、chrome 和 firefox 中运行。
Tried to write it myself, cause i figured it would be a simple code, but after 2 hours of trial and error with no luck, i am starting to run out of options.
试图自己编写它，因为我认为这将是一个简单的代码，但是经过 2 个小时的反复试验但没有运气，我开始没有选择了。
Hopefully a Javascript pro out there got time to help out a very novice user ;)
希望 Javascript 专家有时间帮助一个非常新手的用户 ;)
Thanks
谢谢

If you're willing to use jQuery, you can use this simple function to do it:
如果你愿意使用 jQuery，你可以使用这个简单的函数来做到这一点：
window.setInterval(function(){
$("#divToClick").trigger("click");
}, 1000);
That will call it every 1000 milliseconds, or 1 second
这将每 1000 毫秒或 1 秒调用一次
For a pure Javascript solution, you should take a look at How to trigger event in Javascript
对于纯 Javascript 解决方案，您应该查看如何在 Javascript 中触发事件
or, if you're not interested in supporting IE, you can do it the simple way, with an Event()constructor, and event.dispatch()
或者，如果你对支持 IE 不感兴趣，你可以用一个简单的方法，用一个Event()构造函数，然后event.dispatch()

What's wrong with
怎么了
document.getElementById(id).click()
回答by adeneo
You'd use the event constructorand dispatchEventfor that :
您将使用事件构造函数，dispatchEvent为此：
var support = true; // check if event constructor is supported
try {
if (new MouseEvent('click', {bubbles: false}).bubbles !== false) {
support = false;
} else if (new MouseEvent('click', {bubbles: true}).bubbles !== true) {
support = false;
}
} catch (e) {
support = false;
}
setInterval(function() {
if (support) {
var event = new MouseEvent('click');
}else{
var event = document.createEvent('Event');
event.initEvent('click', true, true);
}
elem.dispatchEvent(event);
},1000);
