tabs addTab时会重复触发tabload事件 - jQuery MiniUI

function openHistData(data) {
let row = grid.getSelected();
let tabs = window.parent.tabs;
//打开参数补录页面
let url = RootPath() + "/prod_operation_data.html";
if (tabs) {
let tab = {
name: 'prodOprationTab',
title: '参数录入',
url: url,
iconCls: 'fa fa-file-text-o',
showCloseButton: true
};
if (tabs.getTab(tab.name)){
tabs.removeTab(tab.name);
}
tab = tabs.addTab(tab);
tabs.activeTab(tab);
//tabload事件会被触发多次
tabs.on("tabload",function(e){
let tab=e.tab;
var iframe=tabs.getTabIFrameEl(tab);
let row = grid.getSelected();
let orgId = row.ORG_ID;
let stationId = row.STATION_ID;
let dateReport = row.DATE_REPORT;
let bcCode = row.BC_NAME;
//跨页面调用tab里面新页面的方法，传参数过去
iframe.contentWindow.openTab(orgId, stationId, dateReport, bcCode)
});
} else {
window.open(url, "_blank")
}
}

点击tab页签时，其相关的页面才会被“懒加载”，而且只加载一次。<br />
Tab1演示了，只要点击就加载，加载多次。
