我如何在提示上做两行或更多行

Question

我如何在提示上做两行或更多行？

我做：

var firstLine = "1st Line";
var secondLine = "2nd Line";
var thirdLine = "3rd Line"
var myTips = firstLine +' '+ secondLine +' '+ thidrLine

我得到"1st Line 2nd Line 3rd Line"

关于我想要的提示

"1st Line
2nd Line
3rd Line"

我怎么能想要它？ 我尝试'\ n'和'\ r \ n'而我没有得到理想的结果

Answer 1

var myTips = firstLine +'<br>'+ secondLine +'<br>'+ thidrLine;
