這篇文章主要介紹了Jquery.Form 異步提交表單的簡單實例。需要的朋友可以過來參考下,希望對大家有所幫助
http://www.vaikan.com/docs/jquery.form.plugin/jquery.form.plugin.html# 1. 在你的頁面裡寫一個表單。一個普通的表單,不需要任何特殊的標記: 代碼如下: <form id="myForm" method="post" action="/Home/AjaxForm"> <div> Name:<input id="username" name="username" type="text" /> Password:<input id="password" name="password" type="text" /> <br /> <input type="submit" value="submit async" id="lnkSubmit" /> </div> </form> 在沒有Jquery.Form組件的時候,提交表單,頁面會進入阻塞模式,等待服務器端的響應。 2. 引入jQuery和Form Plugin Javascript腳本文件並且添加幾句簡單的代碼讓頁面在DOM加載完成後初始化表單: <head> <script type="text/javascript" src="path/to/jquery.js"></script> <script type="text/javascript" src="path/to/form.js"></script> <script type="text/javascript"> // wait for the DOM to be loaded $(document).ready(function() { // bind 'myForm' and provide a simple callback function // 為myform綁定ajaxForm異步提交事件,並提供一個簡單的回調函數。 $('#myForm').ajaxForm(function() { alert("Thank you for your comment!"); }); }); </script> </head> 加上jquery.form組件後,提交表單時,頁面不會再同步提交,而是由js做異步提交,因此提交後頁面不會有刷新。 3. 加入能夠與服務器端進行交互的回調函數。 代碼如下: $(document).ready(function () { //options是一個ajaxForm的配置對象。? var options = { //target: '#output1', // target element(s) to be updated with server response //beforeSubmit: showRequest, // pre-submit callback <FONT color=#ff0000> success: callBackFunc // post-submit callback</FONT> // other available options: //url: url // override for form's 'action' attribute //type: type // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) //clearForm: true // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind form using 'ajaxForm' $('#myForm').ajaxForm(options); }); // responseText是服務端的響應值。statusText是頁面 // 提交狀態值,success表示成功。 function callBackFunc(responseText, statusText) { if (statusText == 'success') { alert(responseText); } else{ alert(“服務端錯誤!”); } } 如果返回的是json數據則回調函數可以這麼寫 function resultFunction(responseText,statusText) { if (statusText == 'success') { if (responseText.code == 1) { alert(responseText.message); } else { alert('error occurs!'); } } else { alert('服務器錯誤!'); } } 服務端的代碼如下: 代碼如下: [HttpPost] public ActionResult AjaxForm(FormCollection form) { string message = "Name:" + form["username"] + " PWD: "+form["password"] ; //return Content(message); return Json(new { code = 1, message = message }); } 4. 加入提交前的數據校驗函數 為options對象添加 beforeSubmit屬性 代碼如下: var options = { //target: '#output1', // target element(s) to be updated with server response <FONT color=#ff0000>beforeSubmit: checkData, // pre-submit callback </FONT> success: callBackFunc // post-submit callback // other available options: //url: url // override for form's 'action' attribute //type: type // 'get' or 'post', override for form's 'method' attribute //dataType: null // 'xml', 'script', or 'json' (expected server response type) //clearForm: true // clear all form fields after successful submit //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // pre-submit callback function checkData(formData, jqForm, options) { // formData is an array; here we use $.param to convert it to a string to display it // but the form plugin does this for you automatically when it submits the data //var queryString = $.param(formData); // jqForm is a jQuery object encapsulating the form element. To access the // DOM element for the form do this: var formElement = jqForm[0]; //alert('About to submit: nn' + queryString); &nb
