问题描述
(此问题与 此处 )
(This question pertains to the JS-XSL demo found here)
简短地告诉您此演示的目的是什么；它以MS Excel文件作为输入，解析数据并以纯文本格式输出数据.我下载了该软件包(zip)并在本地运行，只需通过Chrome打开html文件即可.
To briefly tell you what this demo is for; it takes a MS Excel file as input, parses the data, and outputs the data in text-only format. I downloaded the package (zip) and ran it locally, simply by opening the html file with Chrome.
问题是，我似乎无法克服以下错误:
The problem is, I just cannot seem to get over the following error:
Uncaught SecurityError: Failed to construct 'Worker': Script at 'file:///C:/Users/David/Desktop/Xlsx%20Demo/xlsworker.js' cannot be accessed from origin 'null'.
上述错误指向html文件的第34行，该行具有以下代码:
And above error points to line 34 of the html file, which has the following code:
/* I changed the file path from './xlsworker.js' to 'xlsworker.js' */
var worker = new Worker('xlsworker.js');
此演示仅包含三个文件:html文件本身和两个javascript文件，一个名为xls.js，另一个名为xlsworker.js.所有这三个文件都在同一目录中，并且位于同一级别.
There are only three files for this demo: the html file itself, and two javascript files, one is named xls.js and the other xlsworker.js. All three files are in the same directory and at the same level.
让我感到莫名其妙的是，大约几个月前，我成功运行了该演示！我无法想象我现在是否在做其他不同的事情.有见识吗?
What's rather baffling to me is, I successfully ran this same demo about a couple months ago! I cannot imagine if I am doing anything differently now. Any insight?
