jQuery复选框选中所有并删除所有 [英] jQuery checkbox check all and remove all

问题描述

好，所以我有这段代码非常适合检查和取消选中表单中的所有复选框.但是，如果您全部选中它们，然后都不选中它们，然后尝试再次全部选中，则不会发生任何事情.

Ok so i have this code that works great for checking and un-checking all of the checkboxes in a form. But if you check them all then check none of them then try to check all again nothing happens.

该如何解决?

$('#yearall').click(function() {
    var c = this.checked;
    $('.year:checkbox').prop('checked',c);
});
$('#yearNone').click(function() {
    var c = this.checked;
    $('.year:checkbox, #yearall').removeProp('checked',c);
});

推荐答案

更改

$('#yearNone').click(function() {
    var c = this.checked;
    $('.year:checkbox, #yearall').removeProp('checked',c);
});

到

$('#yearNone').click(function() {
    $('.year:checkbox, #yearall').prop('checked',false);
});

删除属性后，就不能再在#yearAll点击处理程序中进行设置.

Once you remove the property, you can no longer set it in the #yearAll click handler.
