function add_win() {

var add_winForm = new Ext.form.FormPanel({
width: 360,
height: 120,
plain: true,
layout: "form",
defaultType: "textfield",
labelWidth: 75,
baseCls: "x-plain",
//锚点布局-
buttonAlign: "center",
bodyStyle: "padding:0 0 0 0",
items:
[
{
fieldLabel: "属性名称",
width: 160,
id: "prname",
name: "prname",
maxLength: 20,
maxLengthText: '属性名称长度不能超过20位！',
allowBlank: false,
blankText: "请填写属性名称！"
}

]
});

var syswin = new Ext.Window({
title: "新建属性",
width: 360,
height: 120,
plain: true,
iconCls: "addicon",
//不可以随意改变大小
resizable: false,
//是否可以拖动
//draggable:false,

closeAction: 'close',
closable: true,
//弹出模态窗体
modal: 'true',
buttonAlign: "center",
bodyStyle: "padding:10px 0 0 10px",
items: [add_winForm],
buttons: [{
text: "保 存",
minWidth: 70,
handler: function() {
if (add_winForm.getForm().isValid()) {
add_winForm.getForm().submit({
url: '../ajax/s/s_operate.aspx',
waitTitle: '请稍等...',
waitMsg: '正在提交信息...',
params: { t: "add" },
success: function(fp, o) {
if (o.result.success == true) {
syswin.close();
//                                        Store1.reload();

}
else {
msg('信息提示', '添加时出现异常！');
}
},
failure: function() {
msg('信息提示', '添加失败！');
}
});

}
}
}, {
text: "关 闭",
minWidth: 70,
handler: function() {
syswin.close();
}
}]

});

syswin.show();
}

效果：



如果需要修改回显的话那就得调用add_winForm.getForm().load({ // 调用回显的方法 })；

add_winForm.getForm().load({

url: '../ajax/s/s_operate.aspx',
waitMsg: '正在载入数据...',
waitTitle: '请稍等...',
params: { t: "get", prid: prid },
success: function(_form, action) {

},
failure: function(_form, action) {
msg("提示信息", "加载数据时发生异常！");
}

});

效果图：



回显数据：

{success:true,data:{"prname":"222","upprid":"2","typeid":"1"}}
