SpringBoot结合JSR303对前端数据进行校验的示例代码

<input type="text" id="name" name="name" required="true"/>

function submitData(){
		$("#fm").form("submit",{
			url:"/admin/film/save",
			onSubmit:function(){
				var content=CKEDITOR.instances.content.getData();
				if(content==""){
					$.messager.alert("系统提示","内容不能为空！");
					return false;
				}
				return $(this).form("validate");
			},
			success:function(result){
				var result=eval('('+result+')');
				if(result.success){
					$.messager.alert("系统提示","保存成功！");
					resetValue();
				}else{
					$.messager.alert("系统提示","保存失败！");
				}
				
			}
		});
