前台获取query string

[javascript]代码库

        function getArgs(strParame) {
            var args = new Object();
            var query = location.search.substring(1); // Get query string
            var pairs = query.split("&"); // Break at ampersand
            for (var i = 0; i < pairs.length; i++) {
                var pos = pairs[i].indexOf('='); // Look for "name=value"
                if (pos == -1) continue; // If not found, skip
                var argname = pairs[i].substring(0, pos); // Extract the name
                var value = pairs[i].substring(pos + 1); // Extract the value
                value = decodeURIComponent(value); // Decode it, if needed
                args[argname] = value; // Store as a property
            }
            return args[strParame]; // Return the object
        }
