Ext 給後臺提交資料，提交資料有三種方法，注意使用前兩種，我也是隻用全兩種

（第一種）：使用 Form 的父類 basicForm  的submit(Object option )方法，

                      這個方法的使用要求：

       myFormPanel.getForm().submit({
		      clientValidation: true,
			url: 'updateConsignment.php',
			params: {
			newStatus: 'delivered'
			 },
			success: function
 
(form, action) {
				Ext.Msg.alert('Success', action.result.msg);
			},
			failure: function(form, action) {
				switch (action.failureType) {
					case Ext.form.Action.CLIENT_INVALID:
					 Ext.Msg.alert('Failure', 'Form fields may not be submitted with invalid values');
					 break;
					case Ext.form.Action.CONNECT_FAILURE:
					Ext.Msg.alert('Failure'
 
, 'Ajax communication failed');
					break;
					case Ext.form.Action.SERVER_INVALID:
						Ext.Msg.alert('Failure', action.result.msg);
					 }
				}
	});

                             params: 需要傳遞給後臺頁面的引數，如果沒有引數，可以省略

                              success: 資料處理成功後執行的操作

                              failure :    資料處理失敗後執行的操作，

            我的程式例子：

                                     var baseForm = companyFormPaenl.getForm();

                                            if (baseForm.isValid()) {
                                                //彈出效果
                                                Ext.MessageBox.show({
                                                    msg: '正在儲存，請稍等...',
                                                    progressText: 'Saving...',
                                                    width: 300,
                                                    wait: true,
                                                    waitConfig: { interval: 200 }

                                                });

                                                baseForm.submit({
                                                    url: "URL/CompanyInfo/SaveCompanyInfo.aspx",
                                                    method: "POST",
                                                    success: function(form, action) {
                                                        var flag = action.result.success;
                                                        if (flag == true) {
                                                           
                                                            Ext.MessageBox.alert("恭喜", "公司儲存成功!");                                                         

                                                        }

                                                    },
                                                    failure: function(form, action) {

                                                        Ext.MessageBox.alert("提示!", "公司儲存失敗!");

                                                    }

                                                });
                                            }

 （第二種方式）：使用 Ext.Ajax.request(Object option )提交資料

                             這個方法的使用要求：

                          Ext.Ajax.request({


                           url: 'ajax_demo/sample.json',

                           success: function(response, opts) {

                                         var obj = Ext.decode(response.responseText); console.dir(obj);

                                    },

                           failure: function(response, opts) {

                                    console.log('server-side failurewith status code ' + response.status); }

                            });

                       引數介紹：

                                url: 傳送的URL

                                params:  一個包含屬性的物件，他被用作請求的引數

                                method: Http 請求的方式，GET 或者 POST

                                callback: 一個自定義的回撥函式

                                success:function(response,options),當請求成功時呼叫的方法

                                failure:function(response,options) ,當請求失敗是呼叫的方法，

                                （其他引數： Scope ,timeout ,form  ,isUpload）引數很少用

                  我的程式程式碼：

                  Ext.Ajax.request({
                                                url: "URL/CompanyInfo/DeleteCompanyInfo.aspx",
                                                method: "POST",
                                                params: { id: Ext.get("hidCompanyId").dom.value },
                                                success: function(response, options) {
                                                    var jsonObj = Ext.decode(response.responseText);
                                                    if (jsonObj.success == true) {
                                                       
                                                    }
                                                    Ext.Msg.alert("提示", jsonObj.msg);


                                                },
                                                failure: function(response, options) {
                                                    Ext.Msg.alert("提示", "刪除失敗");
                                                }

                                            });
