在一个元素上切换两个类,而不切换兄弟元素

标签: javascript jquery

在我的文件中,我有两个要素。加载时隐藏这些元素的内容。当用户单击该元素的标题或加号时,它将显示内容。目前,当元素显示内容时,如果用户单击文档中的任何位置,它将关闭所打开的元素。我不知道造成这个问题的原因。

这是我的javascript:

function DropDown(element){
    this.title = element;
    this.initEvents();
}

DropDown.prototype = {
    initEvents : function() {
        var obj = this;
        obj.title.on('click', function(event){
        $(this).parent().next('.drop').toggleClass('active');
          event.stopPropagation();
        });
      }
    }

$(function(){
    var title = new DropDown( $('.title'));
    $(document).click(function(){
        $('.drop').removeClass('active');
    });
});

$(document).ready(function() {
    $rotated = false;
    $('.plus, .title').click(function(){
        $(this).toggleClass('rotateOn'); //rotates plus symbol in CSS
    });
});

这不做(我希望它做)是用户点击标题或加号,将显示内容,并且将旋转加号。

这是我的jsFiddle以供参考。由于某些原因,我的小提琴中,加号并没有旋转,但在我正在使用的完整文档中,它确实如此。

这是你的问题,我评论错误的一行:

$(function() {
  var title = new DropDown($('.title'));
  $(document).click(function() {
    //$('.drop').removeClass('active');
  });
});

对于跨度旋转,将其添加到您的css:

span.rotate{
  -moz-transform:rotate(-90deg);
  -webkit-transform:rotate(-90deg);
  -o-transform:rotate(-90deg);
  -ms-transform:rotate(-90deg);
  position: absolute;
}

改变你的功能:

$(document).ready(function() {
  $rotated = false;
  $('.plus, .title').click(function() {
    $(this).toggleClass('rotateOn');
    $(this).children('span').toggleClass('rotate');
  });
});

当然+符号本身不起作用,但如果你使用像+ aaa这样的字符串就可以看到。

完整代码段:

$(function() {
  function DropDown(element) {
    this.title = element;
    this.initEvents();
  }

  DropDown.prototype = {
    initEvents: function() {
      var obj = this;
      obj.title.on('click', function(event) {
        $(this).parent().next('.drop').toggleClass('active');
        event.stopPropagation();
      });
    }
  }

  $(function() {
    var title = new DropDown($('.title'));
    $(document).click(function() {
      //$('.drop').removeClass('active');
    });
  });

  $(document).ready(function() {
    $rotated = false;
    $('.plus, .title').click(function() {
      $(this).toggleClass('rotateOn');
      $(this).children('span').toggleClass('rotate');
    });
  });

  • 的所有权右侧

jsFiddle最近一直很笨,我不确定是否有人注意到了,所以我在Plunker上移动了这个新的演示。

单击整个文档后,您删除了.active类。

https://jsfiddle.net/zer00ne/duLc8bnm/

改变这个:

$(function(){
    var title = new DropDown( $('.title'));
    $(document).click(function(){
        $('.drop').removeClass('active');
    });
});

到此:

$(function() {
   var title = new DropDown($('.title'));
   $('.title').click(function() {
      $(this).removeClass('active');
   });
});
