EXTjs 搜索后 实现分页

GetLoadinvoiceInfo = function() {

var invoiceNumber = Ext.get("invoiceNumberloadT").dom.value;
loadinvoiceDate = Ext.get("DateT").dom.value;
loadinvoiceStore.baseParams.date = loadinvoiceDate;
loadinvoiceStore.reload({
params : {
start : 0,
limit : invoicePage,
invoiceNumber : invoiceNumber,
date : loadinvoiceDate
}
});
