請教各位大神，以下是我的把excel的內容輸出到html的function的部分，最下面是input跟button，目前的方式是利用input的方式選擇excel檔案，然後button送出後顯示檔案內容，想問有沒有辦法把"選擇檔案"的方式，改變成路徑，讓一開啟網頁就已經完成原本的"選擇檔案再送出"這樣的動作?

function myController($scope){
			$scope.uploadExcel = function(){
				var myFile = document.getElementById('file');
				var input = myFile;
				var reader = new FileReader();
				reader.onload = function(){
					var fileData = reader.result;
					var workbook = XLSX.read(fileData, {type: 'binary'});
					workbook.SheetNames.forEach(function(sheetName){
						var rowObject = XLSX.utils.sheet_to_row_object_array(workbook.Sheets[sheetName]);
						excelJsonObj = rowObject;
					});
					for(var  i = 0; i < excelJsonObj.length; i++){
						var data = excelJsonObj[i];
						$('#mySelect').append("<option value='"+data.Column1+"'>"+data.Column1.substring(19));
					}		
				};		
				reader.readAsBinaryString(input.files[0]);
			};
		}
        
        
<form enctype="multipart/form-data">
				<input type="file" id="file">
				<button type="submit" value='submit' ng-click="uploadExcel()"> Reflash </button>
			</form>

那你的檔案路徑哪裡來?

目前是input去選擇檔案，假設是C:\Users\ting\Desktop\test.xlsx這個檔案，選擇後按button後顯示內容，
想要改成一開啟網頁就已經顯示test.xlsx的內容的方法

應該是不行，違反瀏覽器的安全性。

你連真正的路徑好像都拿不到

只會拿到

C:\fakepath\test.xlsx
