Layer.js弹框内如何调用JavaScript方法并传递参数？

function pop_cardsend() {
    layer.open({
        id: "1",
        type: 2,
        title: '标题',
        shadeclose: true,
        shade: 0.6,
        anim: 0,
        area: ['90%', '80%'],
        content: 'if.aspx',
        success: function (layero, index) {
            var childbody = layer.getchildframe('body', index);
            childbody.find('#nav_hiddn').hide();
            childbody.find('#弹出层元素id').val($('#基层元素id').val());
            selectperson( $("#基层元素id").val());
        }
    });
}

function Pop_CardSend() {
    layer.open({
        id: "1",
        type: 2,
        title: '标题',
        shadeClose: true,
        shade: 0.6,
        anim: 0,
        area: ['90%', '80%'],
        content: 'if.aspx?param=' + $("#基层元素id").val(),
        success: function (layero, index) {
            var Childbody = layer.getChildFrame('body', index);
            Childbody.find('#nav_hiddn').hide();
        }
    });
}
