EXT AJAX
这下面例子是一个很好的页面请求的示例，因看到比较好奇 所以转之.若有侵权 还请告之.
/
* 通过Ajax提交数据到后台处理
* ajaxSumitData
* async: true 异步 false 同步
* action: 提交的Action
* param: 提交的参数
* successFunc: 异步提交时,正确返回的回调函数
* failureFunc: 异步提交时,错误返回的回调函数
* */
var msgTip; // 一定要定义在使用前，且定义为全局变量
function ajaxSubmitData(async, action, param, successFunc, failureFunc){
var respText;
if(async){
param = ‘{‘ + param + ‘}’;
var objParam = eval(‘(‘ + param +’)’);
Ext.Ajax.request({
timeout: ,
url:action,
async : async,//同步请求数据
params : objParam,
method : ‘POST’,
success : function(response,options){
respText = Ext.util.JSON.decode(response.responseText);
//msgTip.hide();
if (successFunc != null) {
if(successFunc(respText)) return; // 执行回调函数
}
},
failure : function(response,options){
//msgTip.hide();
if(failureFunc != null){
if(failureFunc(response.responseText)) return; // 执行回调函数
}else{
Ext.Msg.getDialog().setWidth(500);
Ext.Msg.alert(‘提示’,’页面处理请求失败！’);
}
}
});
}else{
var xml = ajaxInit();//new ActiveXObject(“MSXML2.XMLHTTP.4.0”);
xml.open(“POST”, action, false);
xml.setRequestHeader( “Content-Type”, “application/x-www-form-urlencoded”);
xml.send(param);
return xml.responseText;
}
return null;
}
// 同步方法检索数据库中的
function ajaxSearchData(searchField, tableName, condition){
return ajaxSearchDataWithSort(searchField, tableName, condition, null);
}
//同步方法检索数据库中的
function ajaxSearchDataWithSort(searchField, tableName, condition, sort){
var param = “”;
param += “s_method=searchData&”;
param += “s_searchField=” + searchField + “&”;
param += “s_tableName=” + tableName + “&”;
condition = condition.replaceAll(“=”, “”);
param += “s_condition=” + condition + “&”;
if (sort != null && sort != “”) {
param += “s_sort=” + sort + “&”;
}
return ajaxSubmitData(false, global_ctx + “/search/SearchCommon/dbOptJson.do”, param);
}
后台方法
String method = (String) pr.getFilters().get(“method”);
if (“searchData”.equals(method)) {
String con = (String) pr.getFilters().get(“condition”);
con = con.replaceAll(“”, “=”);
// 查询是否为
sql = “select ” + (String) pr.getFilters().get(“searchField”);
sql += ” from ” + (String) pr.getFilters().get(“tableName”);
sql += ” where ” + con;
page = searchDao.selectData(sql, pr.getFilters(), pr);
} else if (“searchDataBySQL”.equals(method)) {
sql = (String) pr.getFilters().get(“sql”);
page = searchDao.selectData(sql, pr.getFilters(), pr);
}
页面调用 示例
var data = ajaxSearchData(“t.cd, t.name”, “COMPANY t “, “t.name = ‘” + name.value + “‘”); if (data != null) { o = eval( “(” + data + “)” ); if (o.totalProperty > 0) { companyCd.options.length = 0; for ( i = 0; i < o.totalProperty ; i ++){ var oOption = document.createElement("OPTION"); oOption.text = o.root[i].name; oOption.value = o.root[i].cd; companyCd.add(oOption); } companyCd.selectedIndex = 0; } }
