监听点击物理返回键及mui.fire父子页面传参

子页面：

plus.key.addEventListener('backbutton', function() {
        console.log("监听到物理返回按键了plusResdy");
        var selfPage = plus.webview.currentWebview();
        var openerPage = selfPage.opener();
        mui.fire(openerPage,'nameFun',{
            strUncertaintyLevelCopy:localStorage.getItem("strUncertaintyLevelCopy"),
            strMetricsCopy:localStorage.getItem("strMetricsCopy"),
            strMeasRangeCopy:localStorage.getItem("strMeasRangeCopy"),
            manufacturerCopy:localStorage.getItem("manufacturerCopy")
        });
        mui.back();
    }, false);

父页面接收子页面传的参数：

window.addEventListener('nameFun',function(event){
    //通过event.detail可获得传递过来的参数内容....
    strUncertaintyLevelPaste = event.detail.strUncertaintyLevelCopy;
    strMetricsPaste = event.detail.strMetricsCopy;
    strMeasRangePaste =event.detail. strMeasRangeCopy;
    manufacturerPaste =event.detail. manufacturerCopy;
//  console.log("计量特性复制值1:"+strUncertaintyLevelPaste+";规格型号复制值1:"+strMetricsPaste+";测量范围复制值1:"+strMeasRangePaste+";生产厂家复制值1:"+manufacturerPaste)
});
