Ext.onReady(function(){
var n = 0;
var ds = new Ext.data.Store({
proxy : new Ext.data.HttpProxy({url : 'userServlet'}),
reader : new Ext.data.JsonReader({
root:'userList'
}, [
{name : 'name',mapping:'name'},
{name : 'email',mapping:'email'}
])
});
var resultTpl = new Ext.XTemplate(
'<tpl for="."><div class="search-item">',
'<h3><span>{name}</h3>',
'{excerpt}',
'</div></tpl>'
);
var simple = new Ext.FormPanel({
labelWidth : 80,
title:'发送邮件',
defaultType : "textfield",
width : 800,
fileUpload : true,
defaults : {
width : 700
},
items :[{
xtype:'combo',
id : 'com',
triggerAction : "all",
mode:'remote',
store: ds,
displayField:'name',
valueField : 'email',
fieldLabel: '发送人',
tpl: resultTpl,
itemSelector: 'div.search-item',
queryParam : 'XXXXX',//用于后台接收
minChars : 2, //两个字符开始查询
typeAhead : true,
typeAheadDelay : 500 //延时查询字符
}]
});
simple.render("show");
});
后台
String email = request.getParameter("XXXXX");
就能得到你输入的值
你再根据这个值进行模糊查询
