我只是想让 JQuery 显示/隐藏 div。我已经尝试使用 Javascript 来代替，但仍然不起作用。我已经测试过以确保我的 JS 脚本中的所有位置都被访问。它只是不适用，我不知道为什么。感谢您提供的任何帮助。
Javascript
$(document).ready(function() {
startup();
$('select').material_select();
$('ul.tabs').tabs();
$('.collapsible').collapsible({
accordion: false // A setting that changes the collapsible behavior to expandable instead of the default accordion style
});
});
function startup() {
$("#Assignments").hide();
$("#ClassView").hide();
}
$('.datepicker').pickadate({
selectMonths: true, // Creates a dropdown to control month
selectYears: 15 // Creates a dropdown of 15 years to control year
});
function tabswitch(x) {
if (x == 1) {
$("#Calender").show();
$("#Assignments").hide();
$("#ClassView").hide();
} else if (x == 2) {
$("#Calender").hide();
$("#Assignments").show();
$("#ClassView").hide();
} else if (x == 3) {
$("#Calender").hide();
$("#Assignments").hide();
$("#ClassView").show();
}
}
CSS
#sidebar p {
text-align: center;
color: white;
font-size: 18px;
}
#sideInterior p {
color: black;
}
.tabs a:link {
font-family: monospace;
color: white
}
.tabs a:hover {
color: gray;
}
.tabs a:visited {
color: white;
}
.tabs a:active {
color: white;
}
body {
background-color: #bdbdbd;
}
.Accordion {
background-color: white;
}
li {
margin-left: 5px;
margin-right: 5px;
}
