提问于 2019-06-04 03:10:28
我是jQuery的新手，看到这个问题已经在几个场合被问到但是在库中找不到答案。
为什么我会继续使用如此简单的脚本获取上述错误消息？我想要做的就是在打开html页面时隐藏课程“回答”

<li>
<div class="question"> Which plan is right for me? <img class="caret" src="/images/chevron.png" width="25"> </div>
<div class="answer"> That’s a good question and there are a number of factors to consider. Reach out to our Customer Success Team-—we’ll be happy to help you figure it out. </div>

<div class="question"> Can I pay monthly? <img class="caret" src="/images/chevron.png" width="25"> </div>
<div class="answer"> Sure. We offer monthly, yearly, and two-yearly plans. A lot of our customers prefer to go for yearly or two-yearly because they’re the most economical choice—you can save up to 32%. But monthly is totally cool, too. </div>

<li>
<div class="question"> Can I use this for my whole organisation, or just my team? <img class="caret" src="/images/chevron.png" width="25"> </div>
<div class="answer"> Either or both! That’s the beauty of dapulse—we have huge enterprises using it organization-wide as well as one and two-people teams.

<li>
<div class="question"> Do you offer discounts? <img class="caret" src="/images/chevron.png" width="25"> </div>

<div class="question"> What type of product support is available? <img class="caret" src="/images/chevron.png" width="25"> </div>
<div class="answer"> The trial is free, but after that, yeah, you’ll need to subscribe to one of our plans to continue using dapulse. Don’t give us that look ;) We’re committed to building an amazing product that provides real and tangible value to you every day. At 16 cents per user a day, our Basic plan sets you back less than a pencil per person. There’s no greater investment than pulling your team together and finding a great way to get work done, and many of our customers tell us that their experience with dapulse is truly invaluable. Imagine never missing another deadline, totally eliminating angry phone calls from clients, or putting an end to painful email threads—for real. Imagine actually enjoying your everyday life at work.

您必须在使用之前添加jQuery库，尝试将以下引用添加到head部分。
