我有以下 CSS 和 HTML：
.dropbtn {
background-color: #4CAF50;
color: white;
padding: 16px;
font-size: 16px;
border: none;
cursor: pointer;
}
.dropdown {
position: relative;
display: inline-block;
}
.dropdown-content {
display: none;
position: absolute;
right: 0;
background-color: #f9f9f9;
box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
z-index: 1;
}
.dropdown-content a {
color: black;
padding: 12px 16px;
text-decoration: none;
display: inline-block;
width: auto;
}
.dropdown-content a:hover {
background-color: #f1f1f1
}
.dropdown:hover .dropdown-content {
display: inline-block;
}
.dropdown:hover .dropbtn {
background-color: #3e8e41; …我正在尝试重写这段代码以满足我的需要,但是我迷失了小提琴手的所有替代魔法.这是我修改过的小提琴.
我的目标是找到段落中"a"字母的所有出现并突出显示它们.我只是无法弄清楚为什么我的信件被替换1$而不是被突出显示.谁能帮我这个 ？
HTML
<div id="searchtext">
<p>I want to highlight all "a" letters in this paragraph</p>
</div>
JS
$(document).ready(function() {
var text = 'a';
var query = new RegExp(text, "gim");
var e = document.getElementById("searchtext").innerHTML;
var enew = e.replace(/(<span>|<\/span>)/igm, "");
document.getElementById("searchtext").innerHTML = enew;
var newe = enew.replace(query, "<span>1$</span>");
document.getElementById("searchtext").innerHTML = newe;
});
CSS:
#searchtext span {
background-color: #FF9;
color: #555;
}
我对 VueJS 比较陌生，现在我正在尝试替换
<script src="https://cdn.jsdelivr.net/npm/vue@2.6/dist/vue.min.js"></script>
经过
<script src="https://unpkg.com/vue@next"></script>
问题是，在此更改之后，以前的工作代码被破坏了：
<script>
window.addEventListener('load', () => {
const defaultOptions = {
position: 'bottom-center'
}
Vue.use(Toasted, defaultOptions) # The error arises here
});
</script>
我遇到了
未捕获的类型错误：Vue.use 不是函数
我在这里做错了什么？
更新：我现在没有使用 webpack。没有 webpack 可以做到这一点吗？
我的问题最好用简单的 JSFiddle 来描述。我想要做的就是让我的下拉菜单宽度取决于其内容宽度，以便所有选项标签都在单行上而没有换行符。
<div>
<span style='cursor:pointer; float:right'>
<div class="btn-group pull-right">
<button id = 'majic' type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">

<ul style = 'padding:10px' class="dropdown-menu">

我正在使用Django JWT启动项目中的身份验证系统。另外，我有一个中间件，问题是在内部，该用户由于某种原因是匿名的，而在该视图中，我可以通过访问该正确的用户request.user。这个问题使我发疯，因为前一段时间该代码运行良好！这是JWT的错误，还是我做错了什么？
class TimezoneMiddleware(MiddlewareMixin):
def process_request(self, request):
# request.user is ANONYMOUS HERE !!!!
if not request.user.is_anonymous:
tzname = UserProfile.objects.get(user = request.user).tz_name
if tzname:
timezone.activate(pytz.timezone(tzname))
