input[type = file]選擇圖片後展示

<input onchange="show(this)" type="file" name="imgs[]" multiple accept="image/gif, image/png, image/jpg, image/jpeg">
<img src="" id="imgs">

        function get_img(f) {
				var rd = new FileReader();//創建文件讀取對象
				var files = f.files[0];//獲取file組件中的文件
				rd.readAsDataURL(files);文件讀取裝換爲base64類型
				rd.onloadend = function(e) {
                                        //加載完畢之後獲取結果賦值給img
					document.getElementById("img").src = this.result;
				}
			}
