jQuery重新加载DIV? (烧瓶/金甲2) [英] JQuery to reload DIV? (Flask/Jinja2)
问题描述
我搜索无济于事.我想我的问题有点独特.我有一个DIV，其中包含一些内容，当前是通过将SQL查询的对象传递到模板中来引入该内容的.效果很好，但是不允许我每隔x秒更新一次内容，而不刷新整个页面.我不想做的事.所以我想知道我可以迫使JQuery重新加载我的DIV元素吗?这还会重新加载其中的代码吗?因为那样会迫使我的div更新.这是代码.
I've searched to no avail.. I guess my question is a bit unique. I have a DIV with some content in it, that content get's brought in currently by passing the object of a SQL query into the template. That works fine, but doesn't allow me to update the content every x seconds, without refreshing the entire page. Something I don't want to do. So I wanted to know I could force JQuery to reload my DIV element? Would this also reload the code in it? Because that would force my div to update.. Here is the code.
<div id=content1>
{{ set content = get_content(parm1, parm2) }} # This is a custom Jinja2 function I wrote to pull the content I need one in the template, but it only runs once.
{% for row in content %}
.. do stuff
{% endfor %}
</div>
是否有可能使JQuery仅仅使用已经存在的代码重新加载该DIV?如果是这样，那应该可以解决我的问题.我曾考虑过尝试创建一个调用以获取JSON中的内容，但如果可能的话，宁愿不这样做.
Is it possible to get JQuery to just reload that DIV with the code that is already there? If so that should fix my issue. I have thought about trying to create a call to get the content in JSON but IF possible would rather not.

app.py
@app.route('/')
def some_view():
name = request.args.get('name', 'Anonymous')
if request.is_xhr:
template_name = 'template_ajax.html'
else:
template_name = 'template.html'
return render_template(template_name, name=name)
template.html
<html>
