<script>

    //点击改变图片大小，再次点击还原

    $(function() {

        $(‘.listbox-pic img’).click(function() {

            var width = $(this).width()

            if (width == 200) {

                $(this).width(600)

                $(this).height(400)

            } else {

                $(this).width(200)

                $(this).height(200)

            }

        })

    })

    //点击显示or隐藏div

    var flag = false

    function displayDiv() {

        var div = document.getElementById(‘commentpart’)

        if (flag) div.style.display = ‘block’

        else div.style.display = ‘none’

        flag = !flag

    }
