js处理url的技巧和归纳

var url = 'http://www.deikang.com/index.php?tel=15811296111&status=1&id=100';
var n = url.indexOf('?');
//alert(n);
var m = url.substring(n + 1, url.length);
//alert(m);
var arr = m.split('&');
//alert(arr);
for (var i in arr) {
  //alert(arr[i]);
  //var reg=new RegExp('tel=');
  var reg = /tel=/;
  if (reg.test(arr[i])) {
    alert(arr[i]);
  }
}

总结：用window.location.search可获得?tel=15811296111&status=1&id=100
