JavaScript：如何防止双击按钮单击或禁用按钮

Question

I have a webpage where multiple user information details is there.so when i click on the complete (here complete button is there beside every user details) button it should do some task(eg. I'm sending mail here) and disable the button after i redirected to same page again. 我有一个网页，其中有多个用户信息详细信息。因此，当我单击“完成”（每个用户详细信息旁边有“完成”按钮）时，它应该执行某些任务（例如，我在此处发送邮件）并禁用该按钮在我再次重定向到同一页面后。 How do I do it? 我该怎么做？ Any possible suggestion? 有什么建议吗？

Answer 1

You can use jquery's .one() method. 您可以使用jquery的.one()方法。

 // prevent anchor to click $(document).ready(function() { var clickCtr = 0; $("a.btn").click( function() { if(clickCtr > 0) { return false; } clickCtr++; }); });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <a href="https://www.google.co.in" target="_blank" class="btn btn-warning">Complete</a>

Answer 2

So there is couple ways to handle your issue. 因此，有几种方法可以解决您的问题。

A simple one from the client side would be to use jQuery (since your importing it in your HTML) to temporarily disable the button. 从客户端来看，一个简单的方法就是使用jQuery（因为您已将其导入HTML）暂时禁用了该按钮。

Here is an exemple: 这是一个例子：

 $(document).ready(function () { clicked = false; $(".btn").on('click', function (event) { if (!clicked) { clicked = true; $(".text").text("Clicked!"); setTimeout(function(){ clicked = false; $(".text").text(""); }, 2000); } else { $(".text").text("Already clicked!"); } }); });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <button class="btn btn-warning">Complete</button> <text class="text"></text>
