JavaScript替换字符串中的（）

Question

我正在使用生成JavaScript文件的Hype API。在该JavaScript文件中是以下变量。

我需要将“＃A0A0A0”的所有实例更改为不同的颜色。可以说：“＃FF0000”。 我还需要将“＃2B2B2B”的所有实例替换为不同的颜色。可以说“#CCCCCC”。

Scene"}]; 

我尝试：

scenes = scenes.replace("#A0A0A0", "#FF0000"); 

但我得到一个对象[对象对象]还没有方法在铬检查员 '替换'错误消息

Answer 1

不能使用.replace函数数组/对象：首先，你必须去高达对象的属性，然后替换为其他一个值：

for(var val in scenes[0].initialValues){ 
    for(var newVal in scenes[0].initialValues[val]){ 
     if(scenes[0].initialValues[val][newVal] == "#A0A0A0"){ 
      scenes[0].initialValues[val][newVal] = "#FF0000"; 
     } 
    } 
} 

Answer 2

scenes是一个数组，所以它没有这种方法。

一个（不是很优雅的）解决方案可能是编码到json你的数组，替换，然后解码它。

另一个解决方案可能是使深层克隆更改值。

这里做一个函数：

// returns a copy of the source structure/array 
// but replaces all instances of oldValue by newValue 
function getCloneWithReplacement(source, oldValue, newValue) { 
    if (source===oldValue) { 
     return newValue; 
    } else if ($.isArray(source)) { 
     var clone = []; 
     for (var i=0; i<source.length; i++) { 
      if (source[i]) clone[i] = getCloneWithReplacement(source[i], oldValue, newValue); 
     } 
     return clone; 
    } else if (typeof(source)=="object") { 
     var clone = {}; 
     for (var prop in source) { 
      if (source[prop]) { 
       clone[prop] = getCloneWithReplacement(source[prop], oldValue, newValue); 
      } 
     } 
     return clone; 
    } else { 
     return source; 
    } 
} 

这两种解决方案可以打破很多东西，如果你对数组的对象定义的方法...操作，只有当它是一个刚刚收到阵列。

第三个解决方案是使用这个（非测试）功能就地替换：

// replaces all instances of oldValue by newValue 
function replace(source, oldValue, newValue) { 
    if ($.isArray(source)) { 
     for (var i=0; i<source.length; i++) { 
      replace(source[i], oldValue, newValue); 
     } 
    } else if (typeof(source)=="object") { 
     for (var prop in source) { 
      if (source[prop]==oldValue) { 
       source[prop]==newValue; 
      } else { 
       replace(source[prop], oldValue, newValue); 
      } 
     } 
    } 
} 

Answer 3

对象的确没有这样的方法。字符串有。
