Question

我有一个使用Bootstrap和Flask构建的Web应用程序，它将Bokeh服务器文档加载到包含div的文件中。散景元素大小调整的响应行为取决于包含div的特定固定初始高度。我在包含自定义CSS的style.css文件中执行此操作：

.placeholderbokehapp {
  height: 1500px;
}

在散景内容加载后，我想立即将.placeholderbokehapp的高度增加到1700px，以容纳其他元素。在Chrome DevTools的“网络”标签中，我看到Bokeh内容加载了autoload.js?bokeh-autoload-element=...脚本，紧接着是jquery和其他所需的js。

以下是base.html中的相关内容：

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

</body>
</html>

使用Flask，我渲染以下模板：

{% extends 'base.html' %}

{% block header %}
{% include 'snowpacktracker/header.html' %}
{% endblock %}

{% block content %}
  <div class="placeholderbokehapp rounded" id="tbc-id">
        {{ wholebokehapp | safe }}
  </div>

{% endblock %}

{% block footer %}
{% include 'snowpacktracker/footer.html' %}
{% endblock %}

wholebokehapp是从URL返回的Bokeh嵌入式服务器文档。

Answer 1

您可以这样做，但是可能有更好的方法

$($('.placeholderbokehapp').css('height', '1700px'))

Answer 2

如果Bokeh正在iframe html标记中加载，则可以在html页面底部加载所有其他js脚本之后编写脚本。

<script>
    $('#tbc-id iframe').load(function(){
        $('#tbc-id').css({height: 1700}) //make container height to 1700px        
       $(this).css({height: 1700}) //make iframe height match the container

    });
</script>

加载脚本时修改div的高度
