jquery: get mouse click if inside a div or not

javascriptjquerymouse

提问by trrrrrrm

i have this HTML page

我有这个 HTML 页面

<html>
<body>
<div>a</div>
<div>b</div>
<div>c</div>
<div>d</div>
<div id='in_or_out'>e</div>
<div>f</div>
</body>
</html>

a,b,c,d,e and f could be divs also not just a plain text.

a,b,c,d,e 和 f 可以是 div,而不仅仅是纯文本。

I want to get the mouse click event, but how could i know if it's inside or outside #in_or_out div ?

我想获得鼠标点击事件,但我怎么知道它是在 #in_or_out div 内部还是外部?

EDIT :: guys, i know how to check if the div is click or not, but i want my event to be fired when the click is outside that div

编辑 :: 伙计们,我知道如何检查 div 是否被点击,但我希望当点击超出该 div 时触发我的事件

$("body > div").click(function() {
    if ($(this).attr("id") == "in_or_out") {
        // inside
    } else {
        // not inside
    }
});

EDIT: just learned, that there is a negate:

编辑:刚刚了解到,有一个否定:

$("body > div:not(#in_or_out)").click(function(e) {
    // not inside
});

If you want to detect whether or not you've clicked inside or outside the div, set the event handler on the documentElementand let it propagate from the other elements upwards:

如果您想检测您是否在 div 内部或外部单击,请在 上设置事件处理程序documentElement并让它从其他元素向上传播:

$("html").click(function (e)
{
    if (e.target == document.getElementById("in_or_out"))
        alert("In");
    else
        alert("Out!");
});

Maybe this one will help you

也许这个会帮助你

$('body').click(function(){
    //do smth
});
$('div#in_or_out').click(function(e){
    e.stopPropagation();
    // do smth else
});

Depends what you want. If you only want to execute code, when it was inside#in_or_out, you can do:

取决于你想要什么。如果你只想执行代码,当它在里面时#in_or_out,你可以这样做:

$('#in_or_out').click(function(){ /* your code here */ });

You can have a status variable that says whether the mouse is in #in_or_outor not:

你可以有一个状态变量来说明鼠标是否在#in_or_out

var inside = false;

$('#in_or_out').hover(function() { inside = true; }, function() { inside = false; });

Then whenever a click occurs you can check with insidewhether the click was inside in_or_outor not.

然后,无论何时发生点击,您都可以检查inside点击是否在内部in_or_out

Reference: .hover()

参考: .hover()

Update:

更新:

No matter to which element you bind the clickhandler, you can always do this:

无论您将click处理程序绑定到哪个元素,您始终可以这样做:

$('element').click(function() {
     if ($(this).attr('id') !== 'in_or_not') {

     }
 });

回答by Bobby

for inside it would be

因为在里面它会是

$("#in_or_out").click(function() {
    // do something here
});

for outside...I've got no idea.

对于外面......我不知道。

Edit:You could try to do the same for body-tag (assigning a click-handler to the document itself). But I'm not sure if both events would fire by that.

编辑:您可以尝试对 body-tag 执行相同的操作(为文档本身分配一个点击处理程序)。但我不确定这两个事件是否会因此而触发。

Like this?

像这样?

$("#in_or_out").click(function() {
    alert("IN DIV!");
});
