通过自己写的方法实现不用ajax的POST方法请求（在网上看到的，感

function post(URL,PARAMS) {        
	    var temp = document.createElement("form");        
	    temp.action = URL;        
	    temp.method = "post";        
	    temp.style.display = "none";        
	    for (var x in PARAMS) {        
	        var opt = document.createElement("textarea");        
	        opt.name = x;        
	        opt.value = PARAMS[x];               
	        temp.appendChild(opt);        
	    }        
	    document.body.appendChild(temp);        
	    temp.submit();        
	    return temp;        
	}        
	
	$(".submit_d a").click(function(){
		var data = ($(this).attr("class")).split("-");
		var series = data[0];
		var discharge = data[1];
		var carriageNum = data[2];
		var seatNum = data[3];
		var gear = data[4];
		var cost = data[5];
		var pictureUrl = data[6];
		var id = data[7];
		post(ctx+"/order/rentcar.action",{"series":series,"discharge":discharge,"carriageNum":carriageNum,"seatNum":seatNum,"gear":gear,"cost":cost,"pictureUrl":pictureUrl,"id":id});
	});
