復(fù)制代碼 代碼如下:
this.departmentStore = new Ext.data.JsonStore({
proxy: new Ext.data.HttpProxy({url: "http://localhost:8080/Test_EXT/DB/Department.php"}),
fields: ["department_code", "department_name", "manager", "division_code"]
});
Department.php，負(fù)責(zé)連接SQL數(shù)據(jù)庫(kù)，取得數(shù)據(jù)并將其轉(zhuǎn)換為JSON格式，為Ext的讀取作準(zhǔn)備。
復(fù)制代碼 代碼如下:
<?php
require('JSON.php');
require('uai_Personal_Info.php');
$p = new uai_Personal_Info();
$result = $p->getDepartmentList();
$json = new Services_JSON();
echo $json->encode($result);
還有一點(diǎn)要修改的就是新增和修改窗體的onSubmitClick方法
onSubmitClick: function() {
if (this.url != "") {
this.form.submit({url: this.url, success: this.onSubmit,
waitTitle: "Save Data", waitMsg: "Transcation process.....", scope: this});
this.fireEvent("submit", this, this.form.getValues());
}
},
Submit方法需要傳遞一系列參數(shù)：
url：數(shù)據(jù)處理的URL地址，這里傳入的是一個(gè)負(fù)責(zé)處理新增操作的URL
success：如果提交數(shù)據(jù)處理成功，則會(huì)回調(diào)這個(gè)參數(shù)指定的處理代碼
waitTitle：數(shù)據(jù)提交時(shí)彈出對(duì)話框的標(biāo)題
waitMsg：數(shù)據(jù)提交時(shí)彈出對(duì)話框的信息內(nèi)容
scope：回調(diào)函數(shù)中的this所指對(duì)象
這里需要說(shuō)明的是處理數(shù)據(jù)的php文件中，必須返回一個(gè)JSON字串，如果包含"success: true"，則表示處理成或，否則認(rèn)為處理失敗。例如下面的代碼
復(fù)制代碼 代碼如下:
<?php
require('JSON.php');
require('uai_Personal_Info.php');
$rs = $_POST;
$rs["success"] = true; //表示處理成功
$sql = "INSERT INTO uai_department(department_code, department_name, manager, division_code) VALUES('" .
$_POST["department_code"] . "', '" . $_POST["department_name"] . "', '" . $_POST["manager"] . "', '" . $_POST["division_code"] . "')";
$p = new uai_Personal_Info();
$rs["r"] = $p->insert_department($sql);
$json = new Services_JSON();
echo $json->encode($rs);
刪除的處理則與新增、修改略有不同，因?yàn)閯h除不需要彈出窗體對(duì)數(shù)據(jù)進(jìn)行操作，所以我們改用Ext.Ajax對(duì)象
復(fù)制代碼 代碼如下:
remove: function() {
var r = this.getActiveRecord();
Ext.Ajax.request({url: "http://localhost:8080/Test_EXT/DB/delete_dept.php", params: {department_code: r.get("department_code")}});
this.getStore().remove(r); //刪除客戶端數(shù)據(jù)
},
