单击jQuery中的链接时如何防止blur()运行? [英] how to prevent blur() running when clicking a link in jQuery?

问题描述

我有:

<input type="text" />

和

$('input').blur(function(){
    alert('stay focused!');
});

我想通过单击锚点元素来防止模糊"时模糊功能的运行.

I want to prevent the blur function running when I'm "blurring" by clicking on an anchor element.

I.E.如果我切换到其他输入，请单击页面上的某处，等等，我希望模糊触发，但是如果我单击链接，则不希望其触发.

I.E. if i tab to another input, click somewhere on the page etc i want the blur to fire, but if i click a link, I don't want it to fire.

这是容易实现的吗，还是我需要与代表和信号灯谈谈?

Is this easily achievable, or do i need to hack about with delegates and semaphores?

谢谢

推荐答案

我今天也必须自己解决此问题.我发现mousedown事件在blur事件之前触发，因此您要做的就是设置一个变量，该变量指示首先发生mousedown事件，然后适当地管理您的blur事件.

I had to solve this problem myself today, too. I found that the mousedown event fires before the blur event, so all you need to do is set a variable that indicates that a mousedown event occurred first, and then manage your blur event appropriately if so.

var mousedownHappened = false;

$('input').blur(function() {
    if(mousedownHappened) // cancel the blur event
    {
        alert('stay focused!');
        $('input').focus();
        mousedownHappened = false;
    }
    else   // blur event is okay
    {
        // Do stuff...
    }
});

$('a').mousedown(function() {
    mousedownHappened = true;
});

希望这对您有帮助！
