Question

我有一个值通过URL中的＃传递这是一个复选框的类名，我想要做的是使用jQuery获取该复选框ID的值

// get hashtag value
if(self.document.location.hash){
var urlhash = self.document.location.hash;
var hashtagval = self.document.location.hash.replace("#","");

// get id of element from hashtagval (class name)
var counter = $('.'+hashtagval).attr('id');
}

好的，我测试了它，并且在散列中添加#a和#b可以正常工作。

除了你滥用哈希属性。 hash属性用于定义页面的视图状态（例如，屏幕应移至此段落），而不是存储一些本地变量，然后将其用于应用程序逻辑！

            <script>
                $(document).ready(function() {
                    var change = true;
                    $('#ba').click(function() {
                        // get hashtag value
                        if(self.document.location.hash) {
                            var urlhash = self.document.location.hash;
                            var hashtagval = self.document.location.hash.replace("#", "");

                            // get id of element from hashtagval (class name)
                            var id = $('.' + hashtagval).attr('id');
                            $('body').append('<h1>id=' + id);
                        }
                    });
                });
            </script>
        </head>
        <body>

            <button type="button" id="ba" >
