如何提交关于Ajax成功的表单:

I'm trying to validate the inputs with jQuery. If the inputs are validated and if ajax returns success Then I need to allow the form to submit. I'm preventing the submit with e.preventDefault

我正在尝试用jQuery验证输入。如果输入被验证，如果ajax返回成功，那么我需要允许表单提交。我用e.preventDefault阻止提交

My Script is :

我的脚本:

$("#spsignin").submit(function(e){
    if (e.preventDefault) { 
        e.preventDefault(); 
    } else { 
        e.returnValue = false;
    }
    var uname = $("input#name").val();
    var pass = $("input#password").val();

    $.ajax({
        type: "POST",
        url: "Login",
        data: 'uname=' + encodeURIComponent(uname) + '&' + 'pass=' 
                       + encodeURIComponent(pass),
        dataType: "json",
        success: function( data, textStatus, jqXHR) {
            if (data == true) {
                $("#spsignin").submit();
            } else { //display error message
                $("#error").show(1500).css({visibility: "visible"});
                $("#error").append("<b>Invalid Username/Email or Password</b>");
            }
        },
        //If there was no resonse from the server
        error: function(jqXHR, textStatus, errorThrown) {
            console.log("Something really bad happened " + textStatus);
            $("#error").html(jqXHR.responseText);
        },
    });

On success it performs submit action but it performing the action repeatedly. Means Firebug showing number of post requests in its console. And number of post requests in response too.

在成功上，它执行提交动作，但它会重复执行动作。表示在其控制台中显示post请求数量的Firebug。以及响应的post请求数量。

And form is:

和形式是:

<form action="Signin" method="get" id="spsignin">
    <input type="text" name="uname" class="text validate[required]" 
        id="name" placeholder="Username"/>
    <input type="password" name="pass" class="text validate[required]" 
        id="password" placeholder="Password"/>
    <input type="submit" value="" id="memberlogin"/>
</form>

Please anyone tell me how to submit the form on ajax success ... Thanks ...

请大家告诉我如何提交ajax success的表单……谢谢……

If the inputs are validated, then you could log the user in, create session from the same code and redirect to appropriate page in your success callback, like

如果输入被验证，那么您可以登录用户，从相同的代码创建会话，并在成功回调中重定向到相应的页面，如

...
success: function( data, textStatus, jqXHR) {
  if(data==true) {
   //redirect to loggedin page
   location.href = "url_to_your_loggedin_page";               
  }
