//点击任意出关闭右键弹窗        $(document).off('click').on('click', function(e) {            $scope.iscontextMenus = false;            if (!$scope.$$phase) {                $scope.$apply();            }        })

//二人会话和群会话消息，右键打开文件功能        $scope.openRightClick = function ($event) {            openRightFile ($event);        }        function openRightFile ($event) {            $event.stopPropagation();            $event.preventDefault();            $scope.iscontextMenus = false;            var content_type = items.content_type,//消息的类型是文本消息还是图片消息还是文档消息                $curTarget = angular.element($event.currentTarget);            switch (content_type){                case eucTypes.rcsTypes.ContentType.ContentTypePICTURE:                    const exec = require('child_process').exec;                    exec('"' + items.file_path + '"');                    break;                case eucTypes.rcsTypes.ContentType.ContentTypeOTHER:                    if ((messageService.FILE_STATE.RECEIVE_SUCCESS == items.file_state) ||                        (messageService.FILE_STATE.SEND_SUCCESS == items.file_state)) {                        const exec = require('child_process').exec;                        exec('"' +items.file_path + '"');                    }                    break;                default :                    break;            }        };        //二人会话和群会话消息，右键保存文件功能        const remote = require('electron').remote;        var fs = require('fs');        $scope.preserveRightClick = function($event){            $event.stopPropagation();            $event.preventDefault();            $scope.iscontextMenus = false; 　　　　　　　　electron调用后返回的回调是一个文件的路径；            const saveFilePath = remote.dialog.showSaveDialog(remote.getCurrentWindow(), {defaultPath:items.file_name}            );            var fileReadStream = fs.createReadStream(items.file_path);            var fileWriteStream = fs.createWriteStream(saveFilePath);            fileReadStream.pipe(fileWriteStream);            fileWriteStream.on('close',function(){                console.log('copy over');            });        }

electron框架提供的应用；const remote = require('electron').remote;remote.dialog.showSaveDialog(remote.getCurrentWindow(), {defaultPath:"abc.txt"});node.js fs模块文件的读入和写出var fs = require('fs');  var fileReadStream = fs.createReadStream('./myjpg.jpg');  var fileWriteStream = fs.createWriteStream('./new_myjpg.jpg');  fileReadStream.pipe(fileWriteStream);  fileWriteStream.on('close',function(){    console.log('copy over');    });

 

上下文contenxmenu属性的应用；  id="supermenu"
