用javascript 接收到params这个参数的值，然后把值用Eval()转换成JSON就可以获取 nums 和category的值
下面函数是获取地址栏值
function getUrlParams() { 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;}
var Params = getUrlParams()["params"];
var object_op = eval(Params);
var nums = object_op.object_op ;
var category = object_op.category;
