使用PrototypeJS将元素转换为数组

invoice[level1][level2][level3]

theString.match(/\\[(.*?)\\]/g)

var str = \'invoice[level1][level2][level3]\';
results = new Array();
str.match(/\\[(.*?)\\]/g).each(
  function(item){ 
    results[results.length] = item.substring(1, item.length - 1);
  }
)
-> results contains -> [\"level1\", \"level2\", \"level3\"]

]

str.substring(str.indexOf(\'[\') + 1, str.length - 1).split(\'][\')
