    <div>
    受到網(wǎng)店的影響,服裝店的生意逐漸有所下降,老板找何問起去談,大概是準備跟上網(wǎng)購潮流,讓何問起準備一下,
    要在網(wǎng)上開網(wǎng)店,要為服裝店建立網(wǎng)站。
    何問起也沒說自己經(jīng)驗不足,只說會積極準備。于是抓緊時間查找資料,學習練習。
    <div><span></span></div>
    </div>
    <script>
    $(".hewenqiToggle").on("click", function () {
    if ($(".hewenqiToggle").css('position') == "absolute") {
    $(".hovertreeContent").height("auto");
    $(".hewenqiToggle").css({ "position": "relative" });
    $(".hewenqiToggle").find("span").removeClass('triangle-down-hovertree').addClass('triangle-up-hovertree');
    }
    else
    {
    $(".hovertreeContent").height("60");
    $(".hewenqiToggle").css({ "position": "absolute" });
    $(".hewenqiToggle").find("span").removeClass('triangle-up-hovertree').addClass('triangle-down-hovertree');
    }
    })
    </script>
    </body>
