How to do "If Clicked Else .."
提问by Tom
I am trying to use jQuery to do something like
我正在尝试使用 jQuery 来做类似的事情
if(jQuery('#id').click) {
//do-some-stuff
} else {
//run function2
}
But I'm unsure how to do this using jQuery ? Any help would be greatly appreciated.
但我不确定如何使用 jQuery 做到这一点？任何帮助将不胜感激。
Edit:I'm trying to run a function if the #id has been clicked and specifically it is has not been clicked then run the function 2 ? i.e. I need to check firstly that the #id has been clicked before running function2?
编辑：如果 #id 已被点击，特别是它没有被点击，我正在尝试运行一个函数，然后运行函数 2 ？即我需要先检查#id 是否在运行前被点击了function2？

You should avoid using global vars, and prefer using .data()
您应该避免使用全局变量，而更喜欢使用 .data()
So, you'd do:
所以，你会这样做：
jQuery('#id').click(function(){
$(this).data('clicked', true);
});
Then, to check if it was clicked and perform an action:
然后，检查它是否被点击并执行操作：
if(jQuery('#id').data('clicked')) {
//clicked element, do-some-stuff
} else {
//run function2
}
Hope this helps. Cheers
希望这可以帮助。干杯

The way to do it would be with a boolean at a higher scope:
这样做的方法是在更高的范围内使用布尔值：
var hasBeenClicked = false;
jQuery('#id').click(function () {
hasBeenClicked = true;
});
if (hasBeenClicked) {
// The link has been clicked.
} else {
// The link has not been clicked.
}

var flag = 0;
$('#target').click(function() {
flag = 1;
});
if (flag == 1)
{
alert("Clicked");
}
else
{
alert("Not clicked");
}

A click is an event; you can't query an element and ask it whether it's being clicked on or not. How about this:
点击是一个事件；你不能查询一个元素并询问它是否被点击。这个怎么样：
jQuery('#id').click(function () {
// do some stuff
});
Then if you really wanted to, you could just have a loop that executes every few seconds with your // run function..
然后，如果你真的想要，你可以有一个循环，每隔几秒执行一次 // run function..

You may actually mean hovering the element by not clicking, right?
您实际上可能是指通过不单击来悬停元素，对吗？
jQuery('#id').click(function()
{
// execute on click
}).hover(function()
{
// execute on hover
});
Clarify your question then we'll be able to understand better.
澄清你的问题，然后我们才能更好地理解。
Simply if an element isn't being clicked on, do a setIntervalto continue the process until clicked.
简单地，如果一个元素没有被点击，请执行 asetInterval继续该过程，直到被点击。
var checkClick = setInterval(function()
{
// do something when the element hasn't been clicked yet
}, 2000); // every 2 seconds
jQuery('#id').click(function()
{
clearInterval(checkClick); // this is optional, but it will
// clear the interval once the element
// has been clicked on
// do something else
})

This is all you need: http://api.jquery.com/click/
这就是你所需要的：http: //api.jquery.com/click/
Having an "else" doesn't apply in this scenario, else would mean "did not click", in which case you just wouldn't do anything.
在这种情况下，“其他”不适用，否则意味着“没有点击”，在这种情况下，您将什么也不做。

Maybe you're looking for something like this:
也许你正在寻找这样的东西：
$(document).click(function(e)
{
if($(e.srcElement).attr('id')=='id')
{
alert('click on #id');
}
else
{
alert('click on something else');
}
});
You may retrieve a pointer to the clicked element using event.srcElement.
您可以使用 检索指向被点击元素的指针event.srcElement。
So all you have to do is to check the id-attribute of the clicked element.
所以你所要做的就是检查被点击元素的 id 属性。

if you press x, x amount of times you will get the division of the checkbox by y which results into a jquery boxcheck which would be an invalid way to do this kind of thing. I hope you will have a look at this before using the .on() functions
如果您按 x, x 次，您将获得复选框除以 y 的结果，这将导致 jquery boxcheck，这将是执行此类操作的无效方法。我希望你在使用 .on() 函数之前先看看这个
