JavaScript中使用正则匹配多条，且获取每条中的分组数据

var str = "字符串字符串<table><tr><th>ID</th><th>姓名</th><th>电话</th></tr><tr><td>01</td><td>张三</td><td>1234567</td></tr><tr><td>02</td><td>李四</td><td>343434</td></tr><tr><td>03</td><td>王五</td><td>685654</td></tr></table>字符串字符串";
var regRecord = new RegExp('\\<tr>\\<td>([0-9]{2})\\<\\/td\\>\\<td>([^\\<]+)\\<\\/td\\>\\<td>([0-9]+)\\<\\/td\\>\\<\\/tr\\>','g');
var fieldIndex = { 'Id' : 1 , 'Name' : 2 , 'Phone' : 3 }
var g_records = [],record;
while ((record = regRecord.exec(str)) != null){
g_records.push({
'Id' : RegExp["$"+fieldIndex.Id]
,'Name' : RegExp["$"+fieldIndex.Name]
,'Phone' : RegExp["$"+fieldIndex.Phone]
});
}
//此时 g_records 就保存了匹配的数据表格，打印出来看看：
for(var i=0;i<g_records.length;i++){
alert("ID:" + g_records[i].Id + ";Name:" + g_records[i].Name + ";Phone:" + g_records[i].Phone);
}
