受到网店的影响,服装店的生意逐渐有所下降,老板找何问起去谈,大概是准备跟上网购潮流,让何问起准备一下,
要在网上开网店,要为服装店建立网站。
何问起也没说自己经验不足,只说会积极准备。于是抓紧时间查找资料,学习练习。
<div class="hewenqiToggle"><span class="triangle-down-hovertree"></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>
</html>
