URL参数解析问题

 

 

 

请编写一个JavaScript函数 parseQueryString，它的用途是把URL参数解析为一个对象，如：var url = ”http://www.taobao.com/index.php?key0=0&key1=1& key2=2…..”
var obj = parseQueryString(url);
alert(obj.key0)  // 输出0

 

传入参数:

 

 <script type="text/javascript">
        var getQuery = function(query) {
            var oQuery = {};
            var iBegin = query.indexOf("?");
            var sQuery = query.substring(iBegin + 1);
            var aQuery = sQuery.split("&"); ;
            for (var i = 0; i < aQuery.length; i++) {
                var k = aQuery[i].indexOf("=");
                if (k == -1) continue;
                var key = aQuery[i].substring(0, k);
                var value = aQuery[i].substring(k + 1);
                oQuery[key] = value;
            }
            return oQuery;
        }
        var test = getQuery("http://www.taobao.com/index.php?key0=0&key1=1&key2=2");
        
    </script>

 

 直接读取网址:

    <script type="text/javascript">
        var parseQueryString = function() {
            var args = new Object();
            var query = window.location.search.substring(1);
            var pairs = query.split("&");
            for (var i = 0; i < pairs.length; i++) {
                var pos = pairs[i].indexOf("=");
                if (pos == -1) continue;
                var argname = pairs[i].substring(0, pos);
                var value = pairs[i].substring(pos + 1);

                args[argname] = value;
            }
            return args;
        }

        var args = parseQueryString();
        alert(args.key1);
    </script>
