You can use \to indicate that the line has not finished yet.
您可以使用\来表示该行尚未完成。
var h= '<label>Hello World, Welcome to the hotel</label> \
<input type="button" value="Visit Hotel"> \
<input type="button" value="Exit">';
Note:When you use \, the whitespace in the following line will also be a part of the string, like this
注意：当你使用时\，下一行的空格也会成为字符串的一部分，像这样
console.log(h);
Output
输出
<label>Hello World, Welcome to the hotel</label> <input type="button" value="Visit Hotel"> <input type="button" value="Exit">
The best method is to use the one suggested by Mr.Alien in the comments section, concatenate the strings, like this
最好的方法是使用Mr.Alien在评论部分建议的方法，连接字符串，像这样
var h = '<label>Hello World, Welcome to the hotel</label>' +
'<input type="button" value="Visit Hotel">' +
'<input type="button" value="Exit">';
console.log(h);
Output
输出
<label>Hello World, Welcome to the hotel</label><input type="button" value="Visit Hotel"><input type="button" value="Exit">

@thefourtheyeanswer is perfect, but if you want, you can also use concatenation here because sometimes \will be misleading, as you will think those are literal characters ..
@thefourtheye 的答案是完美的，但如果您愿意，您也可以在此处使用连接，因为有时\会产生误导，因为您会认为这些是文字字符..
var h = '<label>Hello World, Welcome to the hotel</label>';
h += '<input type="button" value="Visit Hotel"> ';
h += '<input type="button" value="Exit">';
console.log(h);
