layui form 表单ajax 提交

layui.use(['form','jquery'],function(){
			
			//var form = layui.form(),
			var form = layui.form
			$ = layui.jquery ;
			form.on('submit(formDemo)',function(data){
				alert("12312");
				 $.ajax({
					url:'/layui/formSub',
					type:'post',
					data:data.field,
					dataType:'json',
					success:function(data){
						console.log(data)
					}
				}) 
				return false;
			});
		});

1、最后加 return false

2、关于总是提示 TypeError: layui.form is not a function

var form = layui.form() 改为：var form = layui.form
