我在每个阶段 div 中有几个隐藏的 div，称为 Steps。我正在尝试通过单击一个按钮打开所有 div 或折叠所有步骤 div。

我的意图是，Expand View - all steps按钮应该只打开该阶段内的所有 div。它工作一次，但在停止工作后。

我设置了一个小提琴：http: //jsfiddle.net/BuJz8/

jQuery

jQuery(".phaseContent").hide();
jQuery(".stepsContent").hide();
//toggle the componenet with phase level
jQuery(".phaseHeading .heading1").click(function () {
    $(this).toggleClass("active");
    var th = jQuery(this).parent();
    jQuery(th).next(".phaseContent").slideToggle(500);
    return false;
});
jQuery(".stepsHeading .heading1").click(function () {
    $(this).toggleClass("active");
    var th = jQuery(this).parent();
    jQuery(th).next(".stepsContent").slideToggle(500);
    return false;
});

//Expand and collapse toggle

$(".accordion-expand-all").click(function () {
    var contentAreas = $(this).parentsUntil(".phaseContent").find(".stepsContent");
    var expandLink = $(this);
    $(contentAreas).show();
    $(expandLink).text('Collapse - all steps');
    $(this).parentsUntil(".phaseContent").find(".stepsHeading .heading1").toggleClass("active");
    if ($(contentAreas).is(":visible")) {
        $(expandLink).click(function () {
            $(contentAreas).hide();
            $(this).text('Expand - all steps');
        });
    }
    return false;
});

我无法理解你的逻辑。所以我稍微修改了一下。

//Expand and collapse toggle

$(".accordion-expand-all").click(function () {

    var contentAreas = $(this).parentsUntil(".phaseContent").find(".stepsContent");

    var expandLink = $(this);


    if (contentAreas.is(':visible')) {
        contentAreas.hide();
        expandLink.text('Expand View - all steps');
    } else {
        contentAreas.toggleClass("active").show();
        expandLink.text('Collapse - all steps');
    }

    return false;

});

尝试这个。我让它在你更新的 jsfiddle 中工作：http: //jsfiddle.net/BuJz8/1/

该问题是由您click在项目上绑定多个处理程序引起的expandLink。当您绑定多个处理程序时，它们都会触发。

您可以通过对代码进行一些更改来实现您的目标：

$(".accordion-expand-all").click(function () {
    var expandLink = $(this);
    var contentAreas = $(expandLink).closest(".phaseContent").find(".stepsContent");

    // Toggle the content area visibility
    $(contentAreas).toggle();

    // If the content area is now visible
    if ($(contentAreas).is(':visible')) {
        // Change it to the collapse text
        $(expandLink).text('Collapse - all steps');
    } else {
        // Change it to the expand text
        $(expandLink).text('Expand - all steps');
    }

    $(expandLink).closest(".phaseContent").find(".stepsHeading .heading1").toggleClass("active");

    return false;
});

演示

注意：如果您只想选择最近的单个父级，您可能想要使用.closest()而不是。.parentsUntil()后者选择直到但不包括选择器匹配的元素的所有祖先。
