var $ = layui.$;
var verifyName=$(item).attr('name')
, verifyType=$(item).attr('type')
,formElem=$(item).parents('.layui-form')//獲取當前所在的form元素，如果存在的話
,verifyElem=formElem.find('input[name='+verifyName+']')//獲取需要校驗的元素
,isTrue= verifyElem.is(':checked')//是否命中校驗
,focusElem = verifyElem.next().find('i.layui-icon');//焦點元素
if(!isTrue || !value){
//定位焦點
focusElem.css(verifyType=='radio'?{"color":"#FF5722"}:{"border-color":"#FF5722"});
//對非輸入框設置焦點
focusElem.first().attr("tabIndex","1").css("outline","0").blur(function() {
focusElem.css(verifyType=='radio'?{"color":""}:{"border-color":""});
}).focus();
return '必填項不能爲空';
}
}
});
//監聽提交
form.on('submit(demo1)', function(data){
layer.alert(JSON.stringify(data.field), {
title: '最終的提交信息'
})
return false;
});
});
</script>
</body>
</html>
注意：
所有單選和多選這裏都是要設置成一樣子:lay-verify="otherReq"
