多行文本文件輸出html

Question

我正在嘗試將文本文件的行輸出到HTA中的div。 文本本身顯示的很好，但是行沒有延續。 而是將文本大行分組。 如果我打印到msgbox，則會顯示正確且分開的行。

function updateTPtally()
{
    var fso, appdir, messagefile, ts, messagetext, line;
    fso = new ActiveXObject("Scripting.FileSystemObject");

    if (MESSAGE_FILE_NAME7.indexOf("\\") == -1) {
        appdir = unescape(fso.GetParentFolderName(location.pathname));
        messagefile = fso.BuildPath(appdir, MESSAGE_FILE_NAME7);
    } else {
        messagefile = MESSAGE_FILE_NAME7;
    }

    try {
        // Open the message-of-the-day file as a TextStream.
        ts = fso.OpenTextFile(messagefile, 1);
        messagetext = "";
        while (! ts.AtEndOfStream) {
            line = ts.ReadLine();
            // If the line contains text, enclose in <p> element;
            // otherwise, construct a blank line with a nonbreaking space.
            if (line.length > 0)
                line = line.replace(/^(.*)$/, "$1");
            else
                line = "<p>&nbsp;</p>";
            messagetext += line;
        }
        ts.Close();
    }

    // Construct an error message if an error occurred.
    catch(err) {
        messagetext = "<p>Can't display the message of the day.</p>"
        + "<p>&nbsp;</p>"
        + "<p>Error <b>0x" + hex(err.number) + "</b><br />"
        + err.description + "</p>";
    }

    // Update the innerHTML element of the textarea element with the
    document.getElementById("TPtallymemo").innerHTML = messagetext;
}

編輯：我添加了line = line.replace（/ \\ n / g，“
“）;

這似乎可行，但是該文本的第一個單詞。 這是我的文本文件：

Hello.

This should be line two.  And written all in one line.

This should be line three, and also written on one line.

這是我的跨度打印出來的：

Hello.


This
should be line two. And written all in one line.


This
should be line three, and also written on one line.

替換它們后，您無需將其括在文本中。 另外，您不應該封閉不間斷空格，因為段落元素可以正確地彼此分隔。

只是一個小的最后觀察結果：您應該在while條件中調用帶有括號的 AtEndOfStream（）。

messagetext = "";
while (! ts.AtEndOfStream()) {
    line = ts.ReadLine();
    // If the line contains text, enclose in <p> element;
    // otherwise, construct a blank line with a nonbreaking space.
    if (line.length > 0)
        line = line.replace(/^(.*)$/, "<p>$1</p>");
    messagetext += line;
}
