单击按钮时删除类的所有实例
原标题:Remove all instances of class when button clicked

当单击按钮时,我试图删除页面上某个类的所有实例。 代码本身正常工作, 但不是在单击函数中工作。 我拥有的代码是 :

$( #myButton ).click(function() {
    $("#wrapper").removeClass("myClass");
});
问题回答

刚刚刚刚刚刚:

$( #myButton ).click(function() {
    $(".myClass").removeClass("myClass");
});

在页面的任意位置以该类来捕捉到 every 元素 。

$("#wrapper").removeClass("myClass"); 

将只从 # wrapper 元素中删除 MyClass 类( 与 ID “ wrapper ” 元素) 吗?

$( #myButton ).click(function() {
    $("#wrapper .myClass").removeClass("myClass");
});

首先: 将所有元素匹配到包装纸内部的 MyClass 类类, 然后删除它们的 MyClass 类属性

如果我误解了这个问题,请评论,这样我就可以解决答案了。

单击按钮时, 要删除页面上的所有 MyClass 实例, 您可以尝试 :

$( #myButton ).click(function() {
    // this will select all elemets with  myClass 
    var $target = $(".myClass");

    // this will remove  myClass  from the selected elements
    $target.removeClass("myClass");

    // this will remove the selected elements from DOM
    // $target.remove();
});
