所以我有这个注册表单,我如何验证这个,因为每次我提交和eventHough没有数据,每次按下按钮时它都会被添加到数据库中。到目前为止,这是我的代码:
<form id="signupform" class="form" method="post" action="#">
<div class="input-prepend" ><span class="add-on"><i class="glyphicon glyphicon-user"></i></span>
<label for="name">Your Full Name</label>
<input type="text" id="name" name="name" placeholder="your full name" size="40">
</div>
<br />
<div class="input-prepend"><span class="add-on"><i class="glyphicon glyphicon-envelope"></i></span>
<label for="email">Your Email</label>
<input type="email" id="email" name="email" placeholder="your@email.com" size="40" style="color:black;" class="validate" required>
</div>
<br />
<button type="submit" class="btn btn-large" name="action"> Sign Up!</button>
</form>
这就是我的jquery代码:
$(document).ready(function(){
jQuery("#signupform").on("submit",function(e){
e.preventDefault();
var name = jQuery("#name").val();
var email = jQuery("#email").val();
var fd = new FormData();
fd.append("name",name);
fd.append("email",email);
jQuery.ajax({
type: 'POST',
url: 'signup.php',
data: fd,
processData: false,
contentType: false
})
jQuery('#signupform')[0].reset();
});
});
答案 0 :(得分:0)
$(document).ready(function(){
jQuery("#signupform").on("submit",function(e){
e.preventDefault();
var name = jQuery("#name").val();
var email = jQuery("#email").val();
if (!nome || !email || !email.match(/.+@.+[.].+/))
{
alert("complete the form before submit");
return;
}
var fd = new FormData();
fd.append("name",name);
fd.append("email",email);
jQuery.ajax({
type: 'POST',
url: 'signup.php',
data: fd,
processData: false,
contentType: false
})
jQuery('#signupform')[0].reset();
});
});
