Ext异步加载与同步加载
Ext3.0中的同步加载方式:function(url) { function createXhrObject() { var http; var activeX = ['MSXML2.XMLHTTP.3.0', 'MSXML2.XMLHTTP', 'Microsoft.XMLHTTP']; try { http = new XMLHttpRequest(); } catch (e) { for (var i = 0; i < activeX.length; ++i) { try { http = new ActiveXObject(activeX); break; } catch (e) { } } } finally { return http; } }; var conn = createXhrObject(); conn.open("GET", url, false); conn.send(null); if (conn.responseText != '') { return Ext.decode(conn.responseText); } else { return null; } };
Ext3.0中异步加载方式：
Ext.Ajax.request({url : '',params : { },method : 'POST',success : function(response) {var result = Ext.util.JSON.decode(response.responseText);Ext.Msg.alert('信息', result.msg);},failure : function(response, options) {}})
Ext3.0中表单Ajax提交
form.form.submit({waitMsg : '正在提交数据请稍后',// 提示信息waitTitle : '提示',// 标题url : '',// 请求的url地址method : 'POST',// 请求方式success : function(form, action) {// 加载成功的处理函数Ext.Msg.alert('提示', action.result.msg);},failure : function(form, action) {// 加载失败的处理函数Ext.Msg.alert('提示', '');}});
