Javascript语法错误意外标记非法

Question

function queue_instructions(){
        var input_message = "Commands
    w?  Shows whos on the waitlist
    w+  Adds yourself to the waitlist
    w-  Removes yourself from the waitlist
    w++  Moves yourself down one spot on the waitlist
    -mods  Shows a list of available moderators
    -plays  Shows how many songs each DJ has played
    -promote  Requests a vote from everyone for you to be moved to 1st on the list
    -pull [#]  Requests a vote from everyone to pull that DJ off the booth  Number of DJ is     what number spot he is on the booth  Numbers read from left to right
    -remove [#]  Removes that number DJ from the waitlist  Must be a moderator
    -votekick [username]  Requests a vote from everyone to kick the user
     Type -help [command] for more info on a command (ie. -help w?)";
        deliver_chat(input_message);

我在 Google Chrome 上的 Javascript 控制台上收到语法错误意外 toke 非法。有什么想法吗？

Answer 1

您必须关闭每行上的这些引号，并使用 + 连接到下一行：

var input_message = "Commands " + 
    "w?  Shows whos on the waitlist " + 
    "w+  Adds yourself to the waitlist " + 

依此类推

您是否希望在每行中插入换行符？如果是这样，您可以使用 \n：

var input_message = "Commands\n" + 
    "w?  Shows whos on the waitlist\n" + 
    "w+  Adds yourself to the waitlist\n" + 

Answer 2

当您将字符串拆分为多行时，您需要像这样用 + 连接它

var input_message = "Commands"+
"w?  Shows whos on the waitlist"+
"w+  Adds yourself to the waitlist"+
"w-  Removes yourself from the waitlist"+
"w++  Moves yourself down one spot on the waitlist"+
"-mods  Shows a list of available moderators"+
"-plays  Shows how many songs each DJ has played"+;

而且在您的代码中，我没有找到它的右大括号 }功能。

function queue_instructions()
{
     //Stuff here.
}

你需要包含它。

Answer 3

你的语法不正确。您需要将整个字符串放在一行中，或者关闭每行中的引号，并使用 + 将下一行与其连接。

Answer 4

或者你这样做：

var input_message = [
    "Commands",
    "w?  Shows whos on the waitlist",
    "w+  Adds yourself to the waitlist",
    "w-  Removes yourself from the waitlist",
    "w++  Moves yourself down one spot on the waitlist",
    "-mods  Shows a list of available moderators",
    "-plays  Shows how many songs each DJ has played",
    "-promote  Requests a vote from everyone for you to be moved to 1st on the list",
    "-pull [#]  Requests a vote from everyone to pull that DJ off the booth  Number of DJ is what number spot he is on the booth  Numbers read from left to right",
    "-remove [#]  Removes that number DJ from the waitlist  Must be a moderator",
    "-votekick [username]  Requests a vote from everyone to kick the user",
    "Type -help [command] for more info on a command (ie. -help w?)"
].join("\n");

Answer 5

我注意到没有人建议转义行结尾：

var multiStr = "This is the first line \
    This is the second line \
    This is more...";

请注意，行结尾包含在此字符串中...
