采用exec和String.match方法，对于exec必须开启全局匹配g标识才能获取所有匹配
// 需要提取这种数据 <td>2012-12-17</td><td>11:02 , 12:25 , 13:22 , 15:06 , 15:12 , 19:22 , 23:47</td> var rawData = '<table><th scope="col">日期</th><th scope="col">签到签退时间</th></tr><tr>' + '<td>2012-12-03</td><td>10:16 , 13:22 , 20:05</td></tr><tr>' + '<td>2012-12-04</td><td>11:16 , 14:22 , 21:05</td></tr><table>'; // 方法一 var regexp = /<td>(\d{4}-\d{2}-\d{2})<\/td><td>(.*?)<\/td>/g; // 加上g标识才会全局匹配，否则只匹配一个 var matchedArray = regexp.exec(rawData); while(matchedArray != null) { console.dir(matchedArray); matchedArray = regexp.exec(rawData); } // 方法二 var regexp = /<td>(\d{4}-\d{2}-\d{2})<\/td><td>(.*?)<\/td>/g; // 加上g标识才会全局匹配 var matchedArray = rawData.match(regexp); console.dir(matchedArray); // 方法三 var regexp = /<td>(\d{4}-\d{2}-\d{2})<\/td><td>(.*?)<\/td>/; // 不加g标识 var matchedArray = rawData.match(regexp); console.dir(matchedArray); console.log(matchedArray.index); while(matchedArray != null) { rawData = rawData.substr(matchedArray.index + matchedArray[0].length); matchedArray = rawData.match(regexp); } console.dir(matchedArray);
