javascript - 如何获取 %userprofile%\My Documents\

Question

如果省略 \My Documents\，则以下功能将起作用，但我需要访问我的文档。

OpenTextFile("test.txt");

function OpenTextFile(file) {
    var ObjShell = new ActiveXObject("Shell.Application");
    var wShell   = new ActiveXObject("WScript.Shell");
    var path     = wShell.ExpandEnvironmentStrings("%userprofile%\My Documents\");
    ObjShell.ShellExecute("Notepad.exe", file, path, "Open", "1");
}

照原样，它给了我一个错误： Unterminated string constant Line 7 Char 80

Answer 1

你必须记得逃避\- 像这样：

"%userprofile%\\My Documents\\"

Answer 2

在字符串中，\是转义字符。如果你想包含一个\你必须逃避它。

wShell.ExpandEnvironmentStrings("%userprofile%\\My Documents\\");

Answer 3

OpenTextFile("test.txt");

function OpenTextFile(file) {
    var ObjShell = new ActiveXObject("Shell.Application");
    var wShell   = new ActiveXObject("WScript.Shell");
    var path     = wShell.ExpandEnvironmentStrings("%userprofile%\\My Documents\\");
    ObjShell.ShellExecute("Notepad.exe", file, path, "Open", "1");
}
