我已经陷入了一个非常愚蠢和神秘的问题几个小时。 JQuery在<script></script>
之间工作,但在从外部文件调用时不起作用。我必须犯一个愚蠢的错误,但在哪里?
我的HTML中有这个(标准的bootstrap导入,正如你所注意到的):
<!-- Bootstrap core JavaScript
================================================== -->
<!-- Placed at the end of the document so the pages load faster -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="../static/js/bootstrap.min.js"></script>
<script src="../../assets/js/docs.min.js"></script>
<!-- IE10 viewport hack for Surface/desktop Windows 8 bug -->
<script src="../../assets/js/ie10-viewport-bug-workaround.js"></script>
<!-- Custom JavaScript
================================================== -->
<div class="col-xs-4">
<div id="my_camera"></div>
<div id="send-button"></div>
</div>
...
现在,如果我直接在文件中编码,如下所示,Title
会按预期显示:
<!-- Custom JavaScript
================================================== -->
<script>$(function() {
$( "#Title" ).append( '<h1 class="text-capitalize">Title</h1>' );
});
</script>
<div class="col-xs-4">
<div id="my_camera"></div>
<div id="Title"></div>
</div>
但是,如果我将{strong>相同代码放在custom.js
中,则不会显示任何内容。以下是custom.js
内容:
$(function() {
$( "#Title" ).append( '<h1 class="text-capitalize">Title</h1>' );
});
修改后的HTML:
<!-- Bootstrap core JavaScript
================================================== -->
<!-- Placed at the end of the document so the pages load faster -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script src="../static/js/bootstrap.min.js"></script>
<script src="../../assets/js/docs.min.js"></script>
<!-- IE10 viewport hack for Surface/desktop Windows 8 bug -->
<script src="../../assets/js/ie10-viewport-bug-workaround.js"></script>
<!-- Custom JavaScript
================================================== -->
<script src="custom.js"></script>
<div class="col-xs-4">
<div id="my_camera"></div>
<div id="Title"></div>
</div>
答案 0 :(得分:0)
事实上,问题似乎与Jquery没有任何关系。我正在使用Flask python框架,似乎我无法将路径设置为static
以外的目录。因此应用程序看不到static
以外的任何内容。

<script src="../static/js/custom.js"></script>
custom.js内容:
$(document).ready(function () {
$( "#left-col" ).append( '<h1 class="text-capitalize">Title</h1>' );
});

也许你的JS在呈现HTML之前被调用。尝试将其包装在就绪功能中。
$(document).ready(function(){
$( "#Title" ).append( '<h1 class="text-capitalize">Title</h1>' );
});
