js中添加监听，判断是什么事件

 

window.addEventListener('message', function (event) {
        if (event.data.type === "changeMainSrc") {
            changeMainSrcByUrl(event.data.body.url, event.data.body.queryString);
        } else if (event.data.type === "screenshot") {
            if (!contains($scope.latestlist, event.data.body)) {
                $scope.latestlist.push(event.data.body);
            }
        } else if (event.data.type === "closeFrame") {
            $scope.$apply($scope.toMain(event.data.body.url, event.data.body.backUrl));
        } else if (event.data.type === "changeFuncName") {
            $timeout(function () {
                $scope.currentFuc.funcName = event.data.body.name
            });
        } else if (event.data.type === "changeMainSrcNotInFrame") {
            $scope.changeMainSrc(event.data.body.submenu, null, event.data.body.queryString);
            $scope.$apply();
        } else if(event.data.type === "report") {
            handleReportMessage(event);
        } else if(event.data.type === HrUtils.postMessageType.MESSAGE) {
            messageService.sendRequest(event.data.body);
        }
    }, true);
