我创建了一个切换按钮，它通过 4 个状态在单个按钮上切换！

切换按钮位于 GridView 中，而 GridView 又嵌套在 FormView 中。该按钮在 HTML 页面中运行良好，并在选择 4 个图像中的每一个时根据需要将值提交到文本框中。但是在 GridView 中它不起作用！任何人都可以提供帮助或者我应该知道任何已知问题吗？ 

<script type="text/javascript">
   $(document).ready(function() {
     $(".imageButton").ready(function() {
           $("img").click(function() {
               if ($(this).attr("src") == "../../../images/tick_50.png") {
                    $(this).attr("src", '../../../images/excl_mark_50.png'); //orange image
                     $(this).parent().siblings("input").attr("value", '2');
                 } else if ($(this).attr("src") == "../../../images/excl_mark_50.png") {
                     $(this).attr("src", '../../../images/cross_50.png'); //red image
                     $(this).parent().siblings("input").attr("value", '3');
                 } else if ($(this).attr("src") == "../../../images/cross_50.png") {
                     $(this).attr("src", '../../../images/absent_50.png'); //blue image
                     $(this).parent().siblings("input").attr("value", '4');
                 } else if ($(this).attr("src") == "../../../images/absent_50.png") {
                     $(this).attr("src", '../../../images/tick_50.png'); //green image
                     $(this).parent().siblings("input").attr("value", "1");
                }
           });
     });

});
</script>

                if ($(this).attr('src') == '../../../images/tick_50.png') {
