>我有一个表单，当用户多次单击按钮时，数据也将在数据库中保存多次。我这样做是为了限制多次点击以防止这种情况，这是我的代码，但它仍然不起作用。

实现我想要的脚本是这个
<script>
$('form').submit(function () {
$(this).find(':submit').attr('disabled', 'disabled');
});
</script>
我在这里做错了什么？如何在Visual Studio中调试jQuery？
如果您使用的是jQuery v1.6较小版本，则可以在此处使用解决方案
$('form').submit(function() {
$(this).find("input[type='submit']").attr('disabled','disabled');
});
对于 jQuery v1.6 +
$('form').submit(function() {
$(this).find("input[type='submit']").prop('disabled',true);
});
希望这对您有所帮助。
