javascript - 如何在连接 JavaScript 句子时添加空格

Question

我正在通过串联将特定单词插入到句子中，但单词连续在一起，之间没有空格。

var adjective1 = + 'amazing';
var adjective2 = + 'fun';
var adjective3 = + 'entertaining';



var madLib = 'The Intro to JavaScript course is'   + adjective1 +  'james and Julia are so'  + 
adjective2 + 'I cannot wait to work through the rest of this' + adjective3 + 'content!';
console.log(madLib);

Answer 1

只需添加空格

var madLib = 'The Intro to JavaScript course is '   + adjective1 +  ' james and Julia are so'  + 
adjective2 + 'I cannot wait to work through the rest of this ' + adjective3 + ' content!';

变量赋值中的字符串之前也不应该有 +。这将尝试将字符串转换为数字，并会产生 NaN 因为它们不是数字。

var adjective1 = 'amazing';
var adjective2 = 'fun';
var adjective3 = 'entertaining';
