簡單驗證複選框，單選框必填css
例子代碼：html
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>layui</title> <meta name="renderer" content="webkit"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1"> <link rel="stylesheet" href="//res.layui.com/layui/dist/css/layui.css" media="all"> <!-- 注意：若是你直接複製全部代碼到本地，上述css路徑須要改爲你本地的 --> </head> <body> <fieldset class="layui-elem-field layui-field-title" style="margin-top: 50px;"> <legend>初始賦值演示</legend> </fieldset> <form class="layui-form" action="" lay-filter="example"> <div class="layui-form-item"> <label class="layui-form-label">複選框</label> <div class="layui-input-block"> <input type="checkbox" name="like" lay-skin="primary" lay-verify="otherReq" title="寫做"> <input type="checkbox" name="like" lay-skin="primary" lay-verify="otherReq" title="閱讀"> <input type="checkbox" name="like" lay-verify="otherReq" title="遊戲"> </div> </div> <div class="layui-form-item"> <label class="layui-form-label">單選框</label> <div class="layui-input-block"> <input type="radio" name="sex" value="男" lay-verify="otherReq" title="男" > <input type="radio" name="sex" value="女" lay-verify="otherReq" title="女"> </div> </div> <div class="layui-form-item"> <div class="layui-input-block"> <button class="layui-btn" lay-submit="" lay-filter="demo1">當即提交</button> </div> </div> </form> <script src="//res.layui.com/layui/dist/layui.js" charset="utf-8"></script> <!-- 注意：若是你直接複製全部代碼到本地，上述js路徑須要改爲你本地的 --> <script> layui.use(['form', 'layedit', 'laydate'], function(){ var form = layui.form ,layer = layui.layer ,layedit = layui.layedit ,laydate = layui.laydate; //自定義驗證規則 form.verify({ otherReq: function(value,item){ 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，若是存在的話 ,verifyElem=formElem.find('input[name='+verifyName+']')//獲取須要校驗的元素 ,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：web
全部單選和多選這裏都是要設置成同樣子:lay-verify="otherReq"
