Question

我试图使用正则表达式拆分以下字符串，使每个单词，括号，逗号和空格分成字符串。我尝试了很多次，却找不到合适的模式。

var string = "WHEAT flour (49%) (with calcium, iron, niacin, thiamin), butter (MILK), pasteurised EGG, water, MILK, sugar, fresh yeast, salt, powdered pasteurised EGG"

var string = ["WHEAT"," ","flour"," ","(", "49%",")"," ","("," ",")" ......]

有没有人知道如何解决这个问题？

非常感谢你的帮助，尼科

Answer 1

根据您自己想要的输出，您真正需要的是：

([\s,()])

JS代码：

＆＃13;

var string = "WHEAT flour (49%) (with calcium, iron, niacin, thiamin), butter (MILK), pasteurised EGG, water, MILK, sugar, fresh yeast, salt, powdered pasteurised EGG";
console.log(string.split(/([\s,()])/));

＆＃13;

Answer 2

我不确定我的意图是否正确，但我会说你可以使用这个简单的正则表达式：

var string = "WHEAT flour (49%) (with calcium, iron, niacin, thiamin), butter (MILK), pasteurised EGG, water, MILK, sugar, fresh yeast, salt, powdered pasteurised EGG"

var array = string.split(/([\s,()])/);
console.log(array)

在这里，您可以查看正则表达式：https://regex101.com/r/1yYCSN/1

正则表达式输出：var string = ["WHEAT"," ","flour"," ","(", "49%",")"," ","("," ",")" ...]

您期望输出：var string = ["WHEAT"," ","flour"," ","(", "49%",")"," ","("," ",")" ......]

希望我能提供帮助。
