combobox的失去焦点事件

[奔跑的梦想]

<input id="wenhao">

$(function () {
$('#wenhao').combobox({
valueField: 'wenhao',
textField: 'wenhao',
panelHeight:'auto',
onChange: function (newValue, oldValue) {
if (newValue != null) {
var wenhao= $('#wenhao').combobox('getText');
if(wenhao == undefined || wenhao == ''){
return;
}
var urlStr = '${pageContext.request.contextPath}/combobox!selectWenhao.action?wn=' + encodeURI(wenhao);
$('#wenhao').combobox("reload", urlStr);
}
}
});
});



$('#wenhao').blur(function (){
alert('进来了');
query2();
});


如上，我做了一个自动完成框，并且设置了这个框的失去焦点事件，但是没效果。
求各位大神指导啊，我该如何改？

easyui已经重新生成一个input对象了，给原来的input绑定blur没用，原来的隐藏起来了，要给easyui生成的input添加blur事件 $(function () { $('#wenhao').combobox({ valueField: 'wenhao', textField: 'wenhao', panelHeight:'auto', onLoadSuccess:function(){ $('#wenhao').next('.combo').find('input').blur(function (){ alert('进来了'); query2(); }); }, onChange: function (newValue, oldValue) { if (newValue != null) { var wenhao= $('#wenhao').combobox('getText'); if(wenhao == undefined || wenhao == ''){ return; } var urlStr = '${pageContext.request.contextPath}/combobox!selectWenhao.action?wn=' + encodeURI(wenhao); $('#wenhao').combobox("reload", urlStr); } } }); });
