cornerstoneWADOImageLoader failed to load a set of dicom

I am using cornerstoneWADOImageLoader to load my dicom from orthanc, but I am new to cornerstone.
I successed to load a dicom file by setting imageId, then I tried to load a series of dicom by setting imageId as an array and wanted to preview them on enableElement by mouse scrolling. Obviously, I failed. So how to display a set of dicom? Appreciate any response!

Here is my vue.js code

        mounted () {
            // const imageId = " wadouri:http:http//127.0.0.1/data/1.dcm";
            const imageId = [
                              "wadouri:http:http//127.0.0.1/data/1.dcm",
                              "wadouri:http:http//127.0.0.1/data/2.com",
                               "wadouri:http:http//127.0.0.1/data/4.dcm",
                               "wadouri:http:http//127.0.0.1/data/5.com",
                            ];
            this.loadAndViewDicom(imageId);
        },
        methods: {
            loadAndViewDicom(imageId) {
                const element = this.$refs.cornerstoneCanvas;
                cornerstone.enable(element);
                cornerstone.loadAndCacheImage(imageId).then(
                    (image) => {
                        cornerstone.displayImage(element,image);
                    },
                    (err) => {
                        console.error(err);
                    }
                );
            },
       }
