Question

我需要重新组织一个古老的cvs数据库，以便可以使用正确的特殊字段名称将其导入电子商务软件。

这是我正在匹配的一些代码。 [ID，类别，制造商，型号]

"1","3","Samsung","Galaxy S III"
"2","3","HTC","One X"

我的正则表达式

".*?".*?".*?".*?(".*?")

我基本上只需要用稍微复杂的对象文字替换制造商，如

{manufacturers: 'Samsung'}

但我似乎无法弄清楚如何有选择地替换第三场比赛。我知道我可以拆分字符串并提取我需要的数据，但我不知道如何替换匹配，以便输出变量看起来像：

"1","3",{manufacturers: 'Samsung'},"Galaxy S III"
"2","3",{manufacturers: 'HTC'},"One X"

感谢您的帮助！

Answer 1

匹配这个：

"(.*?)","(.*?)","(.*?)","(.*?)"

替换为：

"$1","$2",{manufacturers: '$3'},"$4"

示例：

var s='"1","3","Samsung","Galaxy S III"';
var p='"(.*?)","(.*?)","(.*?)","(.*?)"';
var r='"$1","$2",{manufacturers: \'$3\'},"$4"';
console.log(s.replace(new RegExp(p,"g"),r));

输出：

"1","3",{manufacturers: 'Samsung'},"Galaxy S III"

Coffeescript多线正则表达式取代了混乱
