easyui中datagrid和layout的问题

datagrid重新选择url，post和get方法

//查找信息
function searchInfo(){
var status = $('#status').combobox('getValue');
var phone = $('#phone').combobox('getValue');
var startTime = $('#startTime').datetimebox('getValue');
var endTime = $('#endTime').datetimebox('getValue');
var errorType = $('#errorType').combobox('getValue');
var carrieroperator = $('#carrieroperator').combobox('getValue');
var province = $('#province').combobox('getValue');
var info =  $("#searchInfo").textbox('getValue');
$('#info').datagrid({
<%--url: "${pageContext.request.contextPath}/list/miss/condition?status="+status+"&phone="+phone+"&startTime="+startTime+"&endTime="+endTime+"&errorType="+errorType+"&carrieroperator="+carrieroperator+"&info="+info+"&province="+province,--%>
url: "${pageContext.request.contextPath}/list/miss/condition",
method : 'post',
queryParams:{
status : status,
phone : phone,
startTime : startTime,
endTime : endTime,
errorType : errorType,
carrieroperator : carrieroperator,
info : info,
province : province

}
});
}

<div data-options="region:'west',collapsible:true, collapsed:true" title="West" style="width:255px;">

$('#body').layout('collapse','east');
$('#body').layout('collapse','west');

$('#body').layout('expand','east');

$.messager.confirm('INFO', '确定批量修改么?', function(r){
if (r){
$.ajax({
url : '${pageContext.request.contextPath}/list/miss/updateArrStatus',
data : {
arr : arr.toString(),
arr1 : arr1.toString()
},
dataType : 'json',
async : false,
type : 'POST',
success : function(data) {
$.messager.alert('提示', data.msg);
$('#info').datagrid('reload');
}
});
}
});
