LayUI layer.open 按钮居中

,btnAlign: 'c'

举例:

dialogConfirm('分期还款确认', '/xx1/xx2','60%', '80%','确认','关闭','edit-submit',function (index, field) {}


function dialogConfirm(title, url, width, height,confirm, close,submitId, callback) {
    layer.open({
        type: 2
        , title: title
        , content: url
        , area: [width, height]
        ,btnAlign: 'c'
        , btn: ['<i class="layui-icon layui-icon-ok"></i>' + confirm, '<i class="layui-icon layui-icon-return">' + close]
        , yes: function (index, layero) {
            var iframeWindow = window['layui-layer-iframe' + index]
                , submitID = submitId
                , submit = layero.find('iframe').contents().find('#' + submitID);

            iframeWindow.layui.form.on('submit(' + submitID + ')', function (data) {
                var field = data.field; 
                callback(index, field);
            });
            submit.trigger('click');
        }
    });
};
