我正在尝试创建一个应用程序，我可以单击一列中显示的页面中的链接/按钮，并在另一列中显示html而不重新加载页面。我也试图以一种我可以拥有多个链接/按钮的方式来做到这一点，如果我点击不同的链接，它会改变显示。
到目前为止，我通过在绘图html上重绘整个页面来做到这一点，但它很慢。我的视图html看起来像那样
<html>
<head>

.column {

padding: 10px;

/* Create three equal columns that floats next to each other */
.column2 {

padding: 10px;
height: 50.0%; /* Should be removed. Only for demonstration */
}
/* Create three equal columns that floats next to each other */
.column3 {

width: 50.0%;
padding: 10px;

}
/* Clear floats after the columns */
.row:after {

display: table;
clear: both;
}
/* Responsive layout - makes the two columns stack on top of each other instead of next to each other */
@media (max-width: 600px) {
.column {

}
}
</style>
我的情节html 1看起来像
{{ html|safe }}
我的情节html 2看起来像
{{ plot|safe }}
我的应用是这样的，我有两个html，我想在同一页面显示
from flask import *
import os
import matplotlib.pyplot as plt
import numpy as np
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
app.config['DEBUG'] = True
# IF CHANGE THE ROUTE HERE FOR '/<eventid>' works
@app.route('/view/<eventid>')
def page_view(eventid):
global event
event = eventid
print(event)
return render_template('view.html')
@app.route("/plot1")
def plot1():
par1 = str(request.args.get('par1'))
par2 = str(request.args.get('par2'))
par3 = str(request.args.get('par3'))
fname = './static/'+event
if not os.path.exists(fname):
os.mkdir(fname)
f = open(fname+'/example.html', 'w+')
f.write('<HTML><p> \
<body>' \
+par1+par2+par3+'</p> \
<img src="./plot/test.png"> \
</body> </HTML>')
f.close()
#fl = fname+'/example.html'
#fl = 'http://visjs.org/examples/network/nodeStyles/images.html'
fl = fname+'/Network _ Images.html'
return render_template('plot1.html', html='<object width="100%" height="100%" data=\"'+fl+'\"></object>')
@app.route("/plot2")
def plot2():
par1 = str(request.args.get('par1'))
par2 = str(request.args.get('par2'))
par3 = str(request.args.get('par3'))
fname = './static/'+event
if not os.path.exists(fname):
os.mkdir(fname)
fname = fname+'/plot/'
if not os.path.exists(fname):
os.mkdir(fname)
t = np.arange(0.0, 2.0, 0.01)
s = np.sin(2*np.pi*t)
plt.plot(t, s)
plt.xlabel('time (s)')
plt.ylabel('voltage (mV)')
plt.title('About as simple as it gets, folks')
plt.grid(True)
plt.savefig(fname+"/test.png")
fl = fname+'/test.png'
return render_template('plot2.html', plot='<img src=\"'+fl+'\">')
if __name__ == '__main__':
app.run()
非常感谢任何帮助。

您可以使用AJAX从服务器获取内容并在第二列中显示该内容。以下是说明此概念的示例应用程序：
<强> app.py
from flask import Flask, render_template
app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
app.config['DEBUG'] = True
@app.route('/')
def page_view():
return render_template('view.html')
@app.route('/plot')
def plot():
return render_template('plot.html')
if __name__ == '__main__':
app.run()
<强>模板/ view.html
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("a.loadPlot").click(function() {
args = $(this).data('args');
$.ajax({
type: "GET",
data: args,
url: "{{ url_for('plot') }}",
success: function(data) {
$('#targetColumn').html(data)
}
});
});
});
</script>
<style>
.column {
float: left;
width: 33.33%;
padding: 10px;
height: 300px; /* Should be removed. Only for demonstration */
}
</style>
</head>
<body>
<div class="column" style="background-color:#aaa;">
<a href="#" class="loadPlot" data-args='{"par1": 1, "par2": 4, "par3": 10}'>Plot 1</a><br />
<a href="#" class="loadPlot" data-args='{"par1": 5, "par2": 3, "par3": 5}'>Plot 2</a><br />
<a href="#" class="loadPlot" data-args='{"par1": 10, "par2": 9, "par3": 1}'>Plot 3</a><br />
</div>
<div class="column" style="background-color:#bbb;" id="targetColumn">
</div>
</body>
</html>
<强>模板/ plot.html
Plot with args: <br /><br/ >
<ul>
{% for a in request.args %}
<li>{{ a }} - {{ request.args[a] }}</li>
{% endfor %}
</ul>

答案不短，我只能用你提供的部分代码完全完成，但我可以给你一些指导，以便你可以继续。
更改/ PLOT路线以返回json而不是渲染模板。
@app.route('/plot')
def plot():
...
return flask.jsonify(jsongraph)
然后你需要将所有需要的库添加到你的第一个html中，所以包括plotly js。之后，您需要添加ajax调用而不是按钮的链接：
<div class="column" style="background-color:#aaa;">
<span id="link">link text</span>
</div>
<div class="column" style="background-color:#bbb;" id="target">
<!-- DISPLAY SOMETHING HERE -->
</div>
并添加类似（jQuery中的示例）
<script>
$(document).ready(function(){
$.get('/ploty', function(data){
...
Plotly.plot(..., graph.data, graph.layout);
...
});
});
</script>
Idk如何完全按照情节工作，但你需要以某种方式向它提供target div的id。也许您需要清除以前的div内容。
