将函数仅应用于一个div类，而不是全部 [英] Apply function to only one div class, not all

问题描述

我目前正在网站上的位置网页上工作，并且遇到显示/隐藏jquery效果的问题。下面的jQuery激活点击并应用切换div的类，以显示/隐藏它...非常简单。但是，当我添加更多的div与相同的类，并单击激活链接，它运行所有的div的函数。我知道这是一个简单的修复，但我不能弄清楚正确的语法。任何人都可以快速看看这个代码，看看我如何能解决它。我只包括下面的html divs之一。这是当我有多个，导致的问题。请参见此处的示例。

I'm currently working on a location page on a website and am having trouble with a show/hide jquery effect. The jQuery below activates on-click and applies toggles the class of a div to show/hide it... pretty straightforward. However, when I add more divs with the same class and click on the activator link, it runs the functions on all of the divs. I know this is a simple fix, but I can't figure out the right syntax. Could anyone take a quick look at this code and see about how I could fix it. I only included one of the html divs below. It's when I have more than one that causes the problem. See example here.

感谢您，
Taylor

jQuery

$(function(){
    $(".sliding").hide();
    $(".show-hide").show();
    $(".hide-click").show();

    $('.show-hide').click(function(){   
        $(".sliding").slideToggle("slow");
        $(".hide-click").slideToggle("slow");
    });
});

推荐答案

如果我理解正确， .sliding与其.show-hide链接相关联的内容以切换。您可以设置jQuery上下文以找到正确的.sliding元素。这样，你不会认为元素在某个位置，并且你没有绑定到唯一的css id允许更多的灵活性。

If I understand correctly, you're wanting just the .sliding content that's associated with its .show-hide link to toggle. You can set the jQuery context to find the correct .sliding element. This way you don't assume that the element is at a certain position and you're not tied to unique css ids allowing more flexibility.

$(function(){
    $(".sliding").hide();
    $(".show-hide").show();
    $(".hide-click").show();

    $('.show-hide').click(function(){   
        //find the surrounding div
        var location = $(this).parent().parent();

        //find the correct elements within the location block
        $(".sliding",location).slideToggle("slow");
        $(".hide-click",location).slideToggle("slow");
    });
});
