javascript - saveTextAsFile未定义

我正在尝试保存到文件，但出现错误“saveTextAsFile未定义”，请参见下文

<script type='text/javascript' src='SaveTextAsFile.js'></script>

<textarea id="inputTextToSave" style="width:512px;height:256px"></textarea>

<table>
    <tr>
        <td>Filename to Save As:</td>
        <td><input id="inputFileNameToSaveAs"></input></td>
        <td><button onclick="saveTextAsFile()">Save Text to File</button></td>
    </tr>
</table>

我在与HTML相同的目录中的文件SaveTextAsFile.js中具有该函数saveTextAsFile()。

function saveTextAsFile()
{
    var textToWrite = document.getElementById("inputTextToSave").value;
    var textFileAsBlob = new Blob([textToWrite], {type:'text/plain'});
    var fileNameToSaveAs = document.getElementById("inputFileNameToSaveAs").value;

    var downloadLink = document.createElement("a");
    downloadLink.download = fileNameToSaveAs;
    downloadLink.innerHTML = "Download File";
    if (window.webkitURL != null)
    {
        // Chrome allows the link to be clicked
        // without actually adding it to the DOM.
        downloadLink.href = window.webkitURL.createObjectURL(textFileAsBlob);
    }
    else
    {
        // Firefox requires the link to be added to the DOM
        // before it can be clicked.
        downloadLink.href = window.URL.createObjectURL(textFileAsBlob);
        downloadLink.onclick = destroyClickedElement;
        downloadLink.style.display = "none";
        document.body.appendChild(downloadLink);
    }

    downloadLink.click();
}

最佳答案

在脚本标签src的开头添加斜杠以使其对主机绝对，否则，如果您在url中，请说"localhost/foo/bar/"，则
浏览器将尝试从"localhost/foo/bar/SaveTextAsFile.js"加载文件，如果添加斜杠，它将尝试从"localhost/SaveTextAsFile.js"加载文件

<script type='text/javascript' src='/SaveTextAsFile.js'></script>
