Question

我有一个名为 new.xls 的Excel文件，我以 .html 格式保存为 new.html 。我删除了扩展程序，因此文件名只是 new

现在，如果我将文件重命名为 new.xls 。对于以下代码，

<input type="button" onclick='window.open("new.xls")' value="Open File">

生成的文件在Excel中打开。

然后，如果我将文件重命名为 new.html 对于以下代码

<input type="button" onclick='window.open("new.html")' value="Open File">

结果文件将在浏览器中以表格形式打开。

我想将文件名保留为 new 并使用两个不同的按钮，一个用于在Excel中打开文件，另一个用于在浏览器中以html格式打开文件。欺骗浏览器认为该文件是 .xls 或 .html 文件

我尝试使用以下代码

<!DOCTYPE html>
<html>
<body>  
    <input type="button" onclick="openxls()" value="Open File as xls ">
    <input type="button" onclick="openhtml()" value="Open File as html">
</body>
<script>
    function openxls()
        {
         var x = ".xls" 
         var y = "new" + x ;
         window.open(y);
        }

            function openhtml()
        {
         var x = ".html" 
         var y = "new" + x ;
         window.open(y);
        }
</script>
</html>

但我得到了像

这样的结果

Firefox无法在/C:/Users/daniel/Desktop/new.xls中找到该文件。

找不到档案   Firefox无法在/C:/Users/daniel/Desktop/new.html找到该文件。

请帮忙

当我做var blob = new Blob([this.response], {type:"text/plain;charset=utf-8"});

时

结果是

我想在excel中打开文件进行编辑，我希望它能够预览浏览器。

在excel上进行编辑后，您应该可以使用new.xls Blob作为XMLHttpRequest()申请.responseType，"blob"设置为Blob，创建新{从type设置为text/html的响应中{1}}，然后使用URL.createObjectURL()将新创建的Blob作为参数传递给window.open()，以便在浏览器中查看文件一份.html文件。

var request = new XMLHttpRequest();
request.open("GET", "new.xls");
request.responseType = "blob";
request.onload = function() {
  // set `blob` `type` to `"text/html"`
  var blob = new Blob([this.response], {type:"text/html"});
  var url = URL.createObjectURL(blob);
  var w = window.open(url);
}
request.send();

使用HTML，如何将文件作为Excel文件打开？
