如何使jquery click事件仅在首次点击时触发 [英] How to make a jquery click event fire only on first click

问题描述

我有两个div(.basic1和.basic2).我希望.basic1在单击时淡出，而.basic2在我工作得很好的情况下淡出.唯一的问题是，一旦.basic2淡入，如果用户继续单击链接(.navbar1)，它将在该div中一遍又一遍地淡入.我知道我需要使用.bind()函数，但是我似乎无法弄清楚代码中的放置位置.谢谢！

I have two divs (.basic1 and .basic2). I want .basic1 to fadeout on click, and .basic2 to fade in which I have working wonderfully. The only problem is that once .basic2 fades in, if the user continues to click the link (.navbar1), it will fade in this div over and over. I know that I need to use the .bind() function, but I can't seem to figure out where in my code to put it. Thanks!

$(document).ready(function() {
    $('.navbar1').click(function(e){
        e.preventDefault();

        $('.basic2').hide().load('.basic2', function() {
            $(this).delay(600).fadeIn(1000);
            $('.basic1').fadeOut(1000);
        });
    });
});

推荐答案

使用 .one() :

$('.navbar1').one('click', function(e) {

一旦触发click事件，它将解除绑定.

It unbinds the click event once you trigger it.

如果您不想双击某个元素，则应执行以下操作:

If you don't want an element to be double-clicked, something like this should work:

$(document).on('click', '.navbar1:not(.clicked)', function() {
    // ...
});

要使.navbar1不可点击，只需运行$('.navbar1').addClass('clicked').要使其可点击，请执行相反的操作.

To make .navbar1 unclickable, just run $('.navbar1').addClass('clicked'). To make it clickable, do the opposite.
