加载脚本时修改 div 高度
[英]modify div height when script loaded
问题描述
I have a web app built with Bootstrap and Flask that loads a Bokeh server document into a containing div.
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的 div 中。 The responsive behavior of the sizing of the Bokeh elements depends on a specific fixed initial height for the containing div. Bokeh 元素大小的响应行为取决于包含 div 的特定固定初始高度。 I do this in a style.css file that contains my custom css:我在包含我的自定义 css 的style.css文件中执行此操作：
.placeholderbokehapp {
height: 1500px;
}
Immediately after the Bokeh content loads I would like to increase the height of .placeholderbokehapp to 1700px to accommodate additional elements.在 Bokeh 内容加载后，我想立即将.placeholderbokehapp的高度.placeholderbokehapp 1700px 以容纳其他元素。 In the Chrome DevTools Network tab, I see the Bokeh content loaded with an autoload.js?bokeh-autoload-element=... script, immediately followed by jquery and other needed js.在 Chrome DevTools Network 选项卡中，我看到 Bokeh 内容加载了autoload.js?bokeh-autoload-element=...脚本，紧接着是 jquery 和其他需要的 js。
Here is the relevant content in base.html :下面是base.html的相关内容：
<!doctype html>

Using Flask, I render the following template:使用 Flask，我呈现以下模板：
{% 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 is the Bokeh embedded server document that is returned from a URL. wholebokehapp是从 URL 返回的 Bokeh 嵌入式服务器文档。

你可以这样做，但可能有更好的方法
$($('.placeholderbokehapp').css('height', '1700px'))

if the Bokeh is loading within an iframe html tag then you can write a script after loading all other js scripts at the bottom of html page.如果 Bokeh 正在iframe html 标签中加载，那么您可以在 html 页面底部加载所有其他 js 脚本后编写脚本。
<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>
