ES6 字串拼接
字串拼接可以採用如下方式:
方式一 ${var}
var name1 ="Mike";
var age1=20;
var message1=`hello,${name1},your age is ${age1}`;
//這裡的兩個點是鍵盤上數字鍵1左邊的按鍵,而不是單引號哦
alert(message1);
方式二 + 號拼接字元
注意使用三元表示式時,需要用括號括起來
let test = 'my name' + 5 > 3 ? 'yes' : 'no'
輸出: test ---> "no"
let test1 = 'my name' + (5 > 3 ? 'yes' : 'no')
輸出: test1 ---> "my nameyes"
