如何編寫saveTable函數？

function createTable(){ 
 
    var _table = document.getElementById("test"); 
 
    var newRow = _table.insertRow(1); 
 
    var cell0 = newRow.insertCell(0); 
 
    var cell1 = newRow.insertCell(1); 
 
    cell0.innerHTML = "x"; 
 
    cell1.innerHTML = 60; 
 
    } 
 

 
function saveTable(){ 
 
    document.execCommand("saveas",,"/tmp/test.html"); 
 
    }

<p>to create my table</p> 
 
<input type="button" value="to create new table" onclick="createTable()" /> 
 
<input type="button" value="to save table as /tmp/test.html" oncilck="saveTable()" /> 
 
<table id="test" bodrder=1px> 
 
<tr> 
 
    <td>f1</td> 
 
    <td>f2</td> 
 
</tr> 
 
</table>

當表是由函數創建CREATETABLE，我希望得到一個文件/tmp/test.html，其內容如下

<table id="test"> 
 
<tr> 
 
<td>f1</td> 
 
<td>f2</td> 
 
</tr> 
 
<tr> 
 
<td>x</td> 
 
<td>60</td> 
 
</tr> 
 
</table>

如何履行我的saveTable功能來完成這項工作？

爲解釋在這裏你可以使用一個BLOB此：

兩個問題遺蹟。 –

1.位置保存文件 –

我想要的是'/ tmp/test.html'，我得到的代碼是'/ Downloads/_tmp_test.html' –
