Question

我有这样的数组在数组中，一些元素包含(3.5-inch) ,(4-inch),(4-inch 64-bit), (4-inch 64-bit),(64-bit)之类的

[
"iPhone - Simulator - iOS 6.1",
"iPhone - Simulator - iOS 7.1",
"iPhone Retina (3.5-inch) - Simulator - iOS 6.1",
"iPhone Retina (3.5-inch) - Simulator - iOS 7.1",
"iPhone Retina (4-inch) - Simulator - iOS 6.1",
"iPhone Retina (4-inch) - Simulator - iOS 7.1",
"iPhone Retina (4-inch 64-bit) - Simulator - iOS 6.1",
"iPhone Retina (4-inch 64-bit) - Simulator - iOS 7.1",
"iPad - Simulator - iOS 6.1","iPad - Simulator - iOS 7.1",
"iPad Retina - Simulator - iOS 6.1","iPad Retina - Simulator - iOS 7.1",
"iPad Retina (64-bit) - Simulator - iOS 6.1",
"iPad Retina (64-bit) - Simulator - iOS 7.1",
""
]

我需要将括号内的-替换为#，如(3.5#inch) ,(4#inch),(4#inch 64#bit), (4#inch 64#bit),(64#bit)

我怎么可能。

Answer 1

你可以试试这个：

var arr = ["iPhone - Simulator - iOS 6.1", "iPhone - Simulator - iOS 7.1", "iPhone Retina (3.5-inch) - Simulator - iOS 6.1", "iPhone Retina (3.5-inch) - Simulator - iOS 7.1", "iPhone Retina (4-inch) - Simulator - iOS 6.1", "iPhone Retina (4-inch) - Simulator - iOS 7.1", "iPhone Retina (4-inch 64-bit) - Simulator - iOS 6.1", "iPhone Retina (4-inch 64-bit) - Simulator - iOS 7.1", "iPad - Simulator - iOS 6.1", "iPad - Simulator - iOS 7.1", "iPad Retina - Simulator - iOS 6.1", "iPad Retina - Simulator - iOS 7.1", "iPad Retina (64-bit) - Simulator - iOS 6.1", "iPad Retina (64-bit) - Simulator - iOS 7.1", ""];
console.log('before', arr);
var i = arr.length;
while (i--) {
    arr[i] = arr[i].replace(/(-)(inch)/g, '#$2').replace(/(-)(bit)/g, '#$2');
}
console.log('after', arr);

这适用于括号内-的所有可能出现的内容：

var data = [
"iPhone - Simulator - iOS 6.1",
"iPhone - Simulator - iOS 7.1",
"iPhone Retina (3.5-inch) - Simulator - iOS 6.1",
"iPhone Retina (3.5-inch) - Simulator - iOS 7.1",
"iPhone Retina (4-inch) - Simulator - iOS 6.1",
"iPhone Retina (4-inch) - Simulator - iOS 7.1",
"iPhone Retina (4-inch 64-bit) - Simulator - iOS 6.1",
"iPhone Retina (4-inch 64-bit) - Simulator - iOS 7.1",
"iPad - Simulator - iOS 6.1","iPad - Simulator - iOS 7.1",
"iPad Retina - Simulator - iOS 6.1","iPad Retina - Simulator - iOS 7.1",
"iPad Retina (64-bit) - Simulator - iOS 6.1",
"iPad Retina (64-bit) - Simulator - iOS 7.1",
""
];

data = data.map(function(value) {
    // first find the brackets
    return value.replace(/\([^)]*\)/g, function(val) {
        // now replace all occurences of - with #
        return val.replace(/-/g, "#");
    });
});

以下是 jsfiddle-example

Answer 3

var list = [
"iPhone - Simulator - iOS 6.1",
"iPhone - Simulator - iOS 7.1",
"iPhone Retina (3.5-inch) - Simulator - iOS 6.1",
"iPhone Retina (3.5-inch) - Simulator - iOS 7.1",
"iPhone Retina (4-inch) - Simulator - iOS 6.1",
"iPhone Retina (4-inch) - Simulator - iOS 7.1",
"iPhone Retina (4-inch 64-bit) - Simulator - iOS 6.1",
"iPhone Retina (4-inch 64-bit) - Simulator - iOS 7.1",
"iPad - Simulator - iOS 6.1","iPad - Simulator - iOS 7.1",
"iPad Retina - Simulator - iOS 6.1","iPad Retina - Simulator - iOS 7.1",
"iPad Retina (64-bit) - Simulator - iOS 6.1",
"iPad Retina (64-bit) - Simulator - iOS 7.1",
""
]

var new_list = list.map(function(item){
   return item.replace(/\(.*?\)/g, function(m){ 
      return m.replace(/-/g, "#") 
   });
});

Answer 4

您可以使用array.map()，因为：

var replaced = your_arr.map(function(val) {
  return val.replace(/(-)(inch|bit)/, "#$2");
});
console.log(replaced);

replace数组元素包含带字符的括号
