Question

我想使用JavaScript保存文本文件。我要隐藏的另存为弹出式窗口有问题。第二个问题是如何从复选框传递值并将其发送到那些文件。

我在HTA文件中有一个表单，其中VBScript不起作用。在FileSaver.js文件中，我可以看到带有弹出参数的saveAs函数，但是我不确定如何解决此问题。

<!--HTA FILE-->
<html>
<head>
    <HTA:APPLICATION ID="objHTAHelpomatic" APPLICATIONNAME="Checklist" SCROLL="no" SINGLEINSTANCE="yes" WINDOWSTATE="maximize" />
    <meta http-equiv="x-ua-compatible" content="IE=edge">

<script type="text/javascript" language="javascript">
    function saveBtn() {
    var blob = new Blob(["variables should be here"],
    {type: "text/plain;charset=utf-8"}
    );
    saveAs(blob, "myFile.txt");
    };
</script>

<body onload="window.resizeTo(610,670)">

    <input type="checkbox" name="checkbox01" value="1"> first<br>
    <input type="checkbox" name="checkbox02" value="1"> second<br>>
    <button onClick="saveBtn()">run!</button>

我希望将文件保存在没有opoup的位置-与HTA文件位于同一文件夹中。文本文件应包含复选框的值。可以是对/错，是/否，0,1-任意：）

在没有SaveAs弹出窗口的情况下将文本文件保存为javascript
