Question

以下代码在切换可折叠代码时可以正常工作。 font awesome icon有问题。如果单击+标志，它将扩展卡及其工作，但不会变为-标志。

修改

将仅打开1个可折叠对象，活动的可折叠对象必须带有-符号，另一个是+符号，依此类推。

我的语法正确吗？。

$(".colHide").click(function (e) {
  
    $(this).toggleClass("fa fa-plus").toggleClass("fa fa-minus");

    setTimeout(function () {
        $(".clsColHide").find("div.show").removeClass("show").fadeOut("slow", 100);
        $(".colHide ").removeClass().addClass("fa fa-plus float-right colHide");
        if ($(this).hasClass("fa fa-plus"))
            $(e.target).removeClass().addClass("fa fa-minus float-right colHide");
        
    }, 100);
});

Answer 1

您需要的只是not selector，因此您当前的元素不会更新

$(".colHide").click(function (e) {
debugger;
  
  if($(this).hasClass("fa-minus")){
  $(this).removeClass("fa fa-minus").addClass("fa fa-plus")
  }else{
  $(this).removeClass("fa fa-plus").addClass("fa fa-minus");
  }
$(".colHide").not(this).removeClass("fa fa-minus").addClass("fa fa-plus")
    setTimeout(function () {
        $(".clsColHide").find("div.show").removeClass("show").fadeOut("slow", 100);
    }, 100);
});

Answer 2

问题：我单击+标志，它将扩展卡及其工作，但不会变为-标志

解决方案：


您只能使用要为addClass()或removeClass()添加或删除的类名

您所有的代码都是非常正确的，只是添加删除+和-签名代码的条件。

检查以下示例：

$(".colHide").click(function (e) {
    setTimeout(function () {
        $(".clsColHide").find("div.show").removeClass("show").fadeOut("slow", 100);
        $(".colHide ").addClass("fa-plus").removeClass("fa-minus");
        $(e.target).removeClass("fa-plus").addClass("fa-minus");   
    }, 100);
});

Answer 3

我尝试了不同的方法。取而代之的是通过JS管理，我更改了每个标题内的标记。看看下面是否适合您。

$(".colHide").click(function (e) {
    $(this).toggleClass("expanded-header");
});

.collapsed-header .fa-minus { display:none;}
.collapsed-header .fa-plus { display:inline-block;}
.expanded-header .fa-minus { display:inline-block;}
.expanded-header .fa-plus { display:none;}
