检查HTML 5验证是否成功 [英] Checking HTML 5 validation is successful or not
问题描述
我需要检查HTML 5本机验证是否成功。基于此，我需要调用ajax函数。
I need to check whether HTML 5 native validation is successful or not. Based on this I need to call an ajax function.
这里有一个示例代码。 http://jsfiddle.net/inDiscover/4Pbcp/
An example code is here. http://jsfiddle.net/inDiscover/4Pbcp/
还提供如下示例代码。
<!DOCTYPE html>
<html>
<head>
<title>jQuery UI Dialog: Open Dialog on Clicksssssssssss</title>
<link rel="stylesheet" href="../css/jquery-ui.css" />
<link rel="stylesheet" href="../css/style.css" />
<script type="text/javascript" src="../scripts/jquery.js"></script>
<script type="text/javascript" src="../scripts/jquery-ui.js"></script>
<script type="text/javascript" src="../scripts/jquery.validate.js"></script>
<script type="text/javascript">
$(function(){
$("#pop_submit").click(function()
{
alert("am here");
//return false;
});
});
</script>
</head>
<body>
<div id="popup" style="display:block">
<form action="" name="pop_up_form" id="pop_up_form" method="post">
<input class="pop_up_textbox" type="text" name="acct_nmbr" id="acct_nmbr" required maxlength="19" value=""/>
<input type="submit" name="pop_submit" id="pop_submit" style="display:block;" />
</form>
</div>
</body>
</html>
在jquery代码中，我在提交按钮时发出警报。但是我需要在成功进行HTML 5本机验证后才显示此警报。如果任何人可以指出我是如何实现这一点那么我可以在成功的HTML 5本机验证后调用ajax函数而不是警告消息。
Here in the jquery code I have put an alert while submitting the button. But I need to show this alert only after successful HTML 5 native validation. If any one can point me out that is how can I achieve this then I can call an ajax function instead of an alert message after successful HTML 5 native validation.
我知道我们可以使用JQuery Validator通过使用valid（）方法来验证表单，但我不想这样做。我需要知道我的HTML 5原生验证是否成功，如果是，我需要做一些逻辑。
I know we can use JQuery Validator to validate a form by using valid() method but I don't wanna go in that way. I need to know whether my HTML 5 native validation is successful and if it is I need to do some logic.
推荐答案
checkValidity （）方法（HTML5验证API的一部分）应该做你需要的。本教程非常有助于解释本机HTML5表单验证方法： http：// www。 html5rocks.com/en/tutorials/forms/constraintvalidation/ 。
The checkValidity() method (part of the HTML5 validation API) should do what you need. This tutorial is very helpful in explaining the native HTML5 form validation methods: http://www.html5rocks.com/en/tutorials/forms/constraintvalidation/.
