你好我是laravel的新手，为了建立一个学生CMS，我跟着这个tutorial，我有一个datepicker和一个bootstrap模式，当我点击表单按钮时应该弹出，但是即使一切似乎还好，也没有任何表现。 我有一个包含所有样式和js引用的母版页 master.blade.php

我有另一个页面，其中包含添加课程的表单以及datepicker和modal的脚本 manageCourse.blade.php
@extends('layouts.master')
@section('content')
@include('courses.popup.academic')

@endsection
和模态的页面
<div class="modal fade" id="academic-year-show" tabindex="-1" role="dialog" aria-labelled-by="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">

<h4 class="modal-title">Academic year</h4>
</div>
<div class="modal-body">
<div class="row">
<div class="col-sm-12">
<input type="text" name="academic_year" id="new-academic" class="form-control" placeholder="Academic year">
</div>
</div>
</div>
<div class="modal-footer">
<button data-dismiss="modal" class="btn btn-default" type="button">Close</button>
<button class="btn btn-success btn-save-academic" type="button">Save</button>
</div>
</div>
</div>
似乎没有什么工作，每次我收到此错误：未捕获的ReferenceError：$未定义。谁能告诉我为什么日期选择器和模态没有显示？
答案 0 :(得分：4)
您的@yield("script")部分需要在<script src="/js/jquery.js"></script>中的 master.blade.php后 。目前，您正在尝试运行依赖于jQuery可用的代码，方法是扩展master布局并为扩展模板生成一个部分，但是当这个产量发生在jQuery之前时可用。
<script src="/js/jquery.js"></script>
@yield('script')
<script src="/js/jquery-ui-1.10.4.min.js"></script>
...
</body>
或
...
<script src="/js/charts.js"></script>
<script src="/js/jquery.slimscroll.min.js"></script>
@yield('script')
</body>
通常，每当我为@yield js <script>时，我会在master布局中的所有其他{{1}}标记之后执行此操作，但只要您知道您的依赖关系已有在他们被召唤之前已经被加载，一切都很好。
