我有class MyObject: Object {
/**
Primary Key
*/
dynamic var id: String = ""
/**
Some persisted value
*/
dynamic var someString: String?
var nextID: String {
do {
let realm = try Realm()
var id: String = NSUUID().UUIDString
/// NSUUID().UUIDString almost always makes a unique ID on the first try
/// but we'll check after we generate the first one just to be sure
while realm.objectForPrimaryKey(MyObject.self, key: id) != nil {
id = NSUUID().UUIDString
}
return id
} catch let error as NSError {
/// Oops
fatal(error: error.localizedDescription)
}
}
convenience init(someString: String?) {
self.init()
id = nextID
self.someString = someString
save()
}
override class func primaryKey() -> String? {
return "id"
}
func save() {
/// Gotta check this in case the object was created without using the convenience init
if id == "" { id = nextID }
do {
let realm = try Realm()
try realm.write {
/// Add... or update if already exists
realm.add(self, update: true)
}
} catch let error as NSError {
fatalError(error.localizedDescription)
}
}
}
帖子和php的模态引导寄存器帖子，但它在数据库中插入两次数据
我的模态：
ajax和 <div id="register" class="modal fade" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">New Member</h4>
</div>
<div class="modal-body">
<div class="msg"></div>
<form id="regist" action="/model/php/ajax.php" method="post" accept-charset="utf-8" >
<div class="form-group">
<label for="usr">username:</label>
<input type="text" name="user" class="form-control" id="usr">
</div>
<div class="form-group">
<label for="ugame">name in game :</label>
<input type="text" name="ugame" class="form-control" id="ugame">
</div>
<div class="form-group">
<label for="pwd">password :</label>
<input type="password" name="pwd" class="form-control" id="pwd">
</div>
<div class="g-recaptcha" data-sitekey="<?php echo key; ?>"></div>
<button type="submit" id="signup" class="btn btn-success btn-lg">Signup<span class="glyphicon glyphicon-user"></span></button>
</form> </div>
<div class="modal-footer">
<button type="button" class="btn btn-info" data-dismiss="modal">close</button>
</div>
</div>
</div>
</div>
代码：
Ajax发送帖子到[ <script>
$(document).ready(function () {
$("#regist").on("submit", function(e) {
var postData = $(this).serializeArray();
var formURL = $(this).attr("action");
$.ajax({
url: formURL,
type: "POST",
data: postData,
success: function(data, textStatus, jqXHR) {
$('.msg').html(data);
$('.inf').remove();
},
error: function(jqXHR, status, error) {
console.log(status + ": " + error);
}
});
e.preventDefault();
});
$("#signup").on('click', function() {
$("#regist").submit();
});
});
</script>
]，
此处Action="ajax.php"代码：
ajax.php答案 0 :(得分：3)
您要两次发布表单。
单击submit中的form按钮时，会触发submit事件，您可以使用AJAX请求处理该事件：
$("#regist").on("submit", function(e) {
// your AJAX code
});
但是你还为该按钮设置了click事件处理程序：
$("#signup").on('click', function() {
$("#regist").submit();
});
手动触发第二个submit事件。只需完全删除click处理程序，因为表单默认情况下已触发submit事件。
