替换{{事}}在多个字符串包含变量

Question

我试图取代所有这些字符串：

'Apples are {{appleColor}}' 
'Oranges are {{orangeColor}}' 
'My name is {{name}}' 

有了这些：提前

obj = { 
    appleColor: 'red', 
    orangeColor: 'orange', 
    name: 'Todd' 
} 

谢谢！

使用 String.prototype.replace()功能与 更换回调

Answer 1

简单的解决方案：

var str = "'Apples are {{appleColor}}', 'Oranges are {{orangeColor}}', 'My name is {{name}}' ", 
 
    obj = { 
 
     appleColor: 'red', 
 
     orangeColor: 'orange', 
 
     name: 'Todd' 
 
    }; 
 

 
str = str.replace(/{{(\w+)}}/g, function (m, m1) { 
 
    return obj[m1] || m; 
 
}); 
 

 
console.log(str);
