jQuery auto click on a link
提问by Mihai Iorga
Ok, so I searched all over with no answer. Can someone explain why
好的，所以我搜索了所有没有答案。有人可以解释为什么
does not work with .trigger('click')
不适用于 .trigger('click')
<a id="openNew" href="http://www.example.org">Click me</a>
<script type='text/javascript'>
$(window).load(function(){
$('#openNew').addClass("external").attr({ target: "_blank", href: 'http://www.google.com' }).trigger('click');
});
</script>
and it does not work with .click()
它不适用于 .click()
<script type='text/javascript'>
$(window).load(function(){
$('#openNew').addClass("external").attr({ target: "_blank", href: 'http://www.google.com' }).click();
});
</script>
Does not click the link whatever I do. It only works if I click it. How can I make it auto click? Working on this for about 1 hour and is driving me crazy, I know I'm must be doing something stupid.
无论我做什么都不点击链接。它只有在我点击它时才有效。如何让它自动点击？在这方面工作了大约 1 个小时，让我发疯了，我知道我一定是在做一些愚蠢的事情。

I wouldn't mind any other solution in plain JavaScript.
我不介意纯 JavaScript 中的任何其他解决方案。

Use elem[0].click();instead of elem.click();since you want to call the native click function and not just trigger the click event.
使用elem[0].click();而不是elem.click();因为您想调用本机点击函数而不是仅仅触发点击事件。
By the way: Popup blockers will prevent this from actually opening a new window (luckily).
顺便说一句：弹出窗口阻止程序将阻止实际打开一个新窗口（幸运的是）。

Simulating a user physically clicking the link is not possible. Since you are using target='_blank' I presume you want a new window? So you'll need to use window.open. Which popup blockers wont like.
模拟用户物理点击链接是不可能的。由于您使用的是 target='_blank' 我想您想要一个新窗口？所以你需要使用window.open。哪些弹出窗口拦截器不会喜欢。

Karl swedberg在此声明（其中一条评论）
Using .trigger('click') will not trigger the native click event.
使用 .trigger('click') 不会触发原生点击事件。
Doing the following will work:
执行以下操作将起作用：
<a id="openNew" href="http://www.example.org">Click me</a>
<script type='text/javascript'>
$(window).load(function(){
$('#openNew').addClass("external").attr({ target: "_blank", href: 'http://www.google.com' })[0].click();
});
</script>

实际上它被点击了，但没有打开链接..在这里查看http://jsfiddle.net/H2KuF/5/
Probably you need to open new browser window with this link from JS.
可能您需要使用来自 JS 的此链接打开新的浏览器窗口。
here is samples I found:
这是我找到的样本：
function open2(url, opt){
if (opt == 0) // current window
window.location = url;
else if (opt == 1) // new window
window.open(url);
else if (opt == 2) // background window
{window.open(url); self.focus();}
}
