替換{{事}}在多個字符串包含變量

Question

我試圖取代所有這些字符串：

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

有了這些：提前

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

謝謝！

使用 String.prototype.replace()功能與 更換回調

Answer 1

簡單的解決方案：

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);
