如何编写saveTable函数？

显示键

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>

当通过函数createTable创建表时，我想获取一个文件/tmp/test.html，其内容如下

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

如何完成我的saveTable函数来完成这项工作？

您可以为此使用blob，如下所述：

<!DOCTYPE html>

<body>
  <p>to create my table</p>

  <form>
    <input type="button" value="to create new table" onclick="createTable()"> <input type="button" value=

  <table id="test" bodrder="1px">
    <tr>

      <td>f2</td>
    </tr>
  </table>
  
  
   <script>
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() {
	var textToSave = document.getElementById("test").outerHTML;
	var textToSaveAsBlob = new Blob([textToSave], {
			type : "text/html"
		});
	var textToSaveAsURL = window.URL.createObjectURL(textToSaveAsBlob);
	var fileNameToSaveAs = "/tmp/test.html";

	var downloadLink = document.createElement("a");
	downloadLink.download = fileNameToSaveAs;
	downloadLink.innerHTML = "Download File";
	downloadLink.href = textToSaveAsURL;
	downloadLink.onclick = destroyClickedElement;
	downloadLink.style.display = "none";
	document.body.appendChild(downloadLink);

	downloadLink.click();
}

function destroyClickedElement(event) {
	document.body.removeChild(event.target);
}

  </script>

  
</body>
</html>
