下面是jQuery官方給出的完整的Ajax事件列表:
- ajaxStart (Global Event)
This event is broadcast if an Ajax request is started and no other Ajax requests are currently running.- beforeSend (Local Event)
This event, which is triggered before an Ajax request is started, allows you to modify the XMLHttpRequest object (setting additional headers, if need be.) - ajaxSend (Global Event)
This global event is also triggered before the request is run. - success (Local Event)
This event is only called if the request was successful (no errors from the server, no errors with the data). - ajaxSuccess (Global Event)
This event is also only called if the request was successful. - error (Local Event)
This event is only called if an error occurred with the request (you can never have both an error and a success callback with a request). - ajaxError (Global Event)
This global event behaves the same as the local error event. - complete (Local Event)
This event is called regardless of if the request was successful, or not. You will always receive a complete callback, even for synchronous requests. - ajaxComplete (Global Event)
This event behaves the same as the complete event and will be triggered every time an Ajax request finishes.
- beforeSend (Local Event)
- ajaxStop (Global Event)
This global event is triggered if there are no more Ajax requests being processed.
$.post、$.get是一些簡單的方法,如果要處理復雜的邏輯,還是需要用到jQuery.ajax()
一、$.ajax的一般格式
$.ajax({
type: 'POST',
url: url ,
data: data ,
success: success ,
dataType: dataType
});
二、$.ajax的參數描述
參數 描述
url | 必需。規定把請求發送到哪個 URL。 |
data | 可選。映射或字符串值。規定連同請求發送到服務器的數據。 |
success(data, textStatus, jqXHR) | 可選。請求成功時執行的回調函數。 |
dataType | 可選。規定預期的服務器響應的數據類型。 默認執行智能判斷(xml、json、script 或 html)。 |
三、$.ajax需要注意的一些地方:
1.data主要方式有三種,html拼接的,json數組,form表單經serialize()序列化的;通過dataType指定,不指定智能判斷。
2.$.ajax只提交form以文本方式,如果異步提交包含<file>上傳是傳過不過去,需要使用jquery.form.js的$.ajaxSubmit
