JS通过ajax免form提交表单的例子

$("#submit").click(function() {
	var uid = $("#uid").val();
	var password = $("#password").val();
	
	var param = new Object();
	
	param['uid'] = uid;
	param['password'] = password;
	
	console.log(JSON.stringify(param));
	
	$.ajax({
		type: "post",
		dataType: "json",
		url: "login",
		data: JSON.stringify(param),
		success: function(response){
			if(response.code=='0')
			{
				$.toast(response.msg,'text');
				setTimeout('window.location.reload()',1000);
			}else{
				$.toast(response.msg,'text');
			}
		},
		error: function(XmlHttpRequest,textStatus,errorThrown){
			$.toast('系统出错！','text');
		}
	});
});

或者：

$("#submit").click(function() {
	var uid = $("#uid").val();
	var password = $("#password").val();
	
	//定义对象
	var param = new Object();
	param['uid'] = uid;
	param['password'] = password;
	
	$.ajax({
		type: "post",
		dataType: "json",
		url: "bindPost",
		data: param,
		success: function(response){
			if(response.code=='0')
			{
				$.toast(response.msg,'text');
				setTimeout('window.location.reload()',1000);
			}else{
				$.toast(response.msg,'text');
			}
		},
		error: function(XmlHttpRequest,textStatus,errorThrown){
			$.toast('系统出错！','text');
		}
	});
});
