利用layer实现表单完美验证的方法

//基于layer框架之上，验证表单时引用。弹出提示错误
function qxMsg(msgStr) {
 layer.open({
 type: 1,
 title: '提示消息',
 offset: '10%;',
 content: '
'+msgStr+'
',
 btn: '关闭',
 btnAlign: 'c',
 shade: 0.2,
 yes: function() {
  layer.closeAll();
 }
 });
}
　　

//表单验证
function checkForm() {
 var err = "";
 if(!$('input[name="ggName"]').val()) {
 err += "
名称不能为空";
 }
 if(!$('input[name="isId"]').val()) {
 err += "
空间分类不能为空";
 }
 if(err) {
 err = err.substring(5);
 qxMsg(err);
 return 0;
 }
 return 1;
}
　

//提交新增数据
function addGgBaseModel() {
 var flag = checkForm();
 if(flag == 0) return;
 var formData = new FormData(document.getElementById("myform"));
 formData.append("SysType", "10101");
 formData.append("SysName", "qxPC");
 formData.append("ModuleName", "规格型号");
 $.ajax({
 type: 'post',
 url: _URL_BASE + '/ggBaseModel/addGgBaseModel ',
 data: formData,
 cache: false,
 contentType: false,
 processData: false,
 dataType: 'json',
 success: function(retData) {
  console.log(retData);
  if(retData.ReturnType == "1001") {
  qxMsg("添加成功");
  $(".layui-layer-btn0").click(function() {
   $('.modal-backdrop').remove();
   $("#myModal").hide();
   getGgBaseModel();
  })
  } else if(retData.ReturnType == "4004") {
  kickout();
  } else {
  qxMsg(retData.Message);
  }
 },
 error: function(retData) {
  qxMsg("提交数据出错");
 }
 });
};
