我有一个简单的提交表单，在所有浏览器中都可以工作，但是当它到达iPad/iPhone时（顺便说一下，我是iOS世界的新手），出现了问题。
<form action="/Home/Contact" id="contactform" method="post" novalidate="novalidate">
<div class="response"></div>
<p>
<input class="textfield" data-val="true" data-val-length="The Name must be 50 characters or less" data-val-length-max="50" data-val-regex="The Name should not contain special characters" data-val-regex-pattern="^[A-Za-z0-9-_ ]+$" data-val-required="The Name field is required." id="Name" name="Name" placeholder="Name" type="text" value="">
</p><div class="error-holder"><span class="field-validation-valid" data-valmsg-for="Name" data-valmsg-replace="true"></span></div>
<p></p>
<p>
<input class="textfield" data-val="true" data-val-email="The Email field is not a valid e-mail address." data-val-length="The Email must be 200 characters or less" data-val-length-max="200" data-val-required="The Email field is required." id="Email" name="Email" placeholder="Email" type="text" value="">
</p><div class="error-holder"><span class="field-validation-valid" data-valmsg-for="Email" data-valmsg-replace="true"></span></div>
<p></p>
<p>
<input class="textfield" data-val="true" data-val-length="The Subject must be 255 characters or less" data-val-length-max="255" data-val-required="The Subject field is required." id="Subject" name="Subject" placeholder="Subject" type="text" value="">
</p><div class="error-holder"><span class="field-validation-valid" data-valmsg-for="Subject" data-valmsg-replace="true"></span></div>
<p></p>
<p>
<textarea class="textarea" cols="20" data-val="true" data-val-length="The Message must be 2000 characters or less" data-val-length-max="2000" data-val-required="The Message field is required." id="Message" name="Message" placeholder="Message" rows="8"></textarea>
</p><div class="error-holder"><span class="field-validation-valid" data-valmsg-for="Message" data-valmsg-replace="true"></span></div>
<p></p>
<p>
<button type="submit" name="submit" id="submitButton" title="Click here to submit your message!" class="btn btn-red">Submit</button>
</p>
</form>
iPad和iPhone Safari浏览器会忽略jQuery的 $("form").submit() 方法，直接将表单提交到控制器。
以下是我的提交代码：
$("form").submit(function(e){
if (!$("form").valid())
return false;
var name = $('input#Name').val();
var email = $('input#Email').val();
var subject = $('input#Subject').val();
var message = $('textarea#Message').val();
$.ajax({
type: 'post',
url: '/home/contact',
data: JSON.stringify({ name: name, email: email, subject: subject, message: message }),
contentType: "application/json; charset=utf-8",
dataType: "json",
cache: false,
success: function(result) {
//do stuff
},
error: function(result) {
//do stuff
}
})
return false;
});
当我点击提交按钮时，代码根本没有执行。
更新1：
如果我更改为$("#contactform").submit(...)或$("#submitButton").click(...)在iPhone和iPad上仍然没有运气。
更新2
如果我像@Sridhar-R建议的那样使用action="javascript:chk()"，它就可以正常工作。但为什么javascript发布在action="/Home/Contact"时不起作用 - 这是因为在iPhone / iPad上JavaScript发布只能以这种方式工作吗？
