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(wèn)起去談，大概是準(zhǔn)備跟上網(wǎng)購(gòu)潮流，讓何問(wèn)起準(zhǔn)備一下，
要在網(wǎng)上開(kāi)網(wǎng)店，要為服裝店建立網(wǎng)站。
何問(wèn)起也沒(méi)說(shuō)自己經(jīng)驗(yàn)不足，只說(shuō)會(huì)積極準(zhǔn)備。于是抓緊時(shí)間查找資料，學(xué)習(xí)練習(xí)。

$(".hewenqiToggle").on("click", function () {
if ($(".hewenqiToggle").css('position') == "absolute") {
$(".hovertreeContent").height("auto");
$(".hewenqiToggle").css({ "position": "relative" });
$(".hewenqiToggle").find("span").removeClass('triangle-down-hovertree').addClass('triangle-up-hovertree');
