Question

在这里查看此代码，因为您将看到我正在使用jQuery进行一些练习并尝试构建选项卡面板。

一旦我点击了新的部分，我就试图让这些部分移开。

我不知道为什么这对我不起作用。

jquery的

$(function() {

  // capture click of section button
  $("a").click(function(e) {

    // prevent default link behaviour
    e.preventDefault();

     // hide the current active section 
    $(".section .active_section").slideUp(500, function(){
      // then take away their active class
      $(this).removeClass("active_section");
    });

  }); // click function closes here


  // find out what section button is pressed
  var sectionId = $("a").attr("data-sectionId");


  // slide down that section
  $("#"+sectionId).slideDown(500, function(){
    // add the active class
    $(this).addClass("active_section");
  });

});

Answer 1

将您的所有代码移至点击功能，并将其工作;）

https://jsfiddle.net/pgytuq6j/

// capture click of section button
$("a").click(function(e) {

    // prevent default link behaviour
    e.preventDefault();

    // find out what section button is pressed
    var sectionId = $(this).attr("data-sectionId");

    // hide the current active section 
    $(".active_section").slideUp(500, function(){
        // then take away their active class
        $(this).removeClass("active_section");
    });

    // slide down that section
    $("#"+sectionId).slideDown(500, function(){
        // add the active class
        $(this).addClass("active_section");
    });

}); // click function closes here

这是你想要的吗？

代码中的小问题，你必须更加小心小事

Answer 3

当您编写$('.section .activeSection')时 - 这意味着选择具有类activeSection的元素，该类是具有类节的元素的子元素。整个代码也应该在click事件中：

$("a").click(function (e) {

    // prevent default link behaviour
    e.preventDefault();
    var currentAnchor = $(this);
    // hide the current active section 
    $(".active_section").slideUp(500, function () {
        // then take away their active class
        $(this).removeClass("active_section");
        $('.active_button').removeClass('active_button');
        $(currentAnchor).addClass('active_button');
    });

    // find out what section button is pressed
    var sectionId = $(this).attr("data-sectionId");

    console.log(sectionId);
    // slide down that section
    $("#" + sectionId).slideDown(500, function () {
        // add the active class
        $(this).addClass("active_section");

    });
});

检查JS的内联注释

更新了JS

$(function() {
    $("a").click(function(e) {
        e.preventDefault();
        $(".section.active_section").slideUp(500, function(){
            $(this).removeClass("active_section");
        });
        //You need to identify clicked element inside click event itself
        //get the sectionId of clicked element using $(this)
        var sectionId = $(this).attr("data-sectionId");
        $("#"+sectionId).slideDown(500, function(){
            $(this).addClass("active_section");
        });
    });
});

DEMO

以下功能可让您在上下滑动时平滑过渡

$(function() {
  // capture click of section button
  $("a").click(function(e) {

    // prevent default link behaviour
    e.preventDefault();

     // hide the current active section 
    $(".active_section").slideUp(500, function(){        
      // then take away their active class
      $(this).removeClass("active_section");        
        // find out what section button is pressed  
    });

    var sectionId = $(this).attr("data-sectionId");

    setTimeout(function() {
        // slide down that section
        $("#"+sectionId).slideDown(500, function(){
            // add the active class
            $(this).addClass("active_section");
        });
      }, 500);      
  }); // click function closes here  
});
