javascript - 正则表达式提取括号和函数名称

Question

有人帮我为以下情况编写正则表达式

• somestring() => ['somestring']
• somestring()[10] => ['somestring','',10]
• somestring('argString') => ['somestring', 'argString']
• somestring('argString')[10] =>['somestring', 'argString',10]

• somestring({prop1:'v1',prop2:'v2'}) => ['somestring', {prop1:'v1',prop2:'v2'}]

• somestring({prop1:'v1',prop2:'v2'})[100] => ['somestring', {prop1:'v1',prop2:'v2'},100 ]

这是我到目前为止尝试过的

var regExp = /\b[^()]+\((.*)\)+\[(.*?)]/;
var matches = regExp.exec('somestring()[10]');

Answer 1

这可行:

var input = ['somestring()', 'somestring()[10]', "somestring('argString')", "somestring('argString')[10]", "somestring({prop1:'v1',prop2:'v2'})", "somestring({prop1:'v1',prop2:'v2'})[100]"];

console.log(input.map(function(v) {
  let result = v.match(/(.*)\((.*)\)(\[([^\]]*)\])?/);

  return [result[1], result[2], result[4]];
}));
