我正在尝试使用.slideToggle（）显示div部分，但它不起作用。
HTML：
<form>
<a href="#" class="add-sources">Add sources</a>
<!-- Hide until Click -->
<div class="add-sources-interaction" style="display: none;">
<div class="form-group">
<label for="source-1">Sources</label>
<input type="text" name="source-1" class="form-control" placeholder="Source #1" id="source-1">
<input type="text" name="source-2" class="form-control" placeholder="Source #2" id="source-2">
<input type="text" name="source-3" class="form-control" placeholder="Source #3" id="source-3">
</div>
</div>
</form>
<script src="//code.jquery.com/jquery-1.12.0.min.js"></script>
<script src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
jQuery的：
$('.add-sources').click(function(){
$('.add-sources-interaction').slideToggle("fast");
});
我收到此错误：
Uncaught Error: Bootstrap's JavaScript requires jQuery version 1.9.1 or higher, but lower than version 3
at bootstrap.min.js:6
at bootstrap.min.js:6
我在我的应用程序中使用其他jQuery函数，这似乎需要我导入的jQuery版本。
我删除了：
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
.slideToggle（）仍无效。
修改
<script>＃1和＃3替换为<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>的完整文件，

答案 0 :(得分：1)
在您的问题代码中，您有4个<script>代码。删除没有。 1和3.在他们的位置添加此版本的jquery。
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
这是一个工作片段：
$('.add-sources').click(function(){
$('.add-sources-interaction').slideToggle("fast");
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<a href="#" class="add-sources">Add sources</a>
<!-- Hide until Click -->
<div class="add-sources-interaction" style="display: none;">
<div class="form-group">
<label for="source-1">Sources</label>
<input type="text" name="source-1" class="form-control" placeholder="Source #1" id="source-1">
<input type="text" name="source-2" class="form-control" placeholder="Source #2" id="source-2">
<input type="text" name="source-3" class="form-control" placeholder="Source #3" id="source-3">
</div>
