我该怎么做才能将我从python列表中选择的值添加到没有任何js库的输入中？我需要用逗号分别添加它们。问题是我可以选择一个值，而第二次不能选择它，所以我有循环执行它，但是它不起作用。
app.py:
import csv
from flask import Flask, jsonify, make_response, render_template, request,
with open('templates/Testing.csv') as f:
reader = csv.reader(f)
values = next(reader)
values = values[:len(values)-1]
@app.route('/', methods=['GET'])
def page_show():
return render_template('includes/default.html', values=values)
if __name__ == '__main__':
app.run()
default.html:
<input type="text" id="values" list="val" multiple="multiple" class="searchTerm" name="value" placeholder="Type your values">
<select list="values" name="values">
{% for val in values %}
<option value="{{val}}" SELECTED>{{val}}</option>
{% endfor %}
</select>
<button type="submit" class="searchButton" name=form>
<i class="fa fa-search"></i>
</button>
如何解决？谢谢。
发现错误/（ㄒoㄒ）/ ~~
NameError: name 'values' is not defined
类似于app.run（） 从烧瓶导入烧瓶，render_template
app = Flask(__name__)
@app.route('/', methods=['GET'])
def page_show():
values = [1, 2, 3, 4, 5]
print(values)
return render_template('default.html', values=values)
app.run()
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body>
<input
type="text"
id="values"
list="val"
multiple="multiple"
class="searchTerm"
name="value"
placeholder="Type your values"
/>
<select list="values" name="values">
{% for val in values %}
<option value="{{val}}" selected>{{val}}</option>
{% endfor %}
</select>
<button type="submit" class="searchButton" name="form">
<i class="fa fa-search"></i>
</button>
</body>
</html>
有效！
