还有一个关于 Flask 和 jquery 自动完成的问题。我一直在阅读并尝试以下已回答的问题，但没有成功:
Using jQuery autocomplete with Flask
特别是第二个答案完全符合我的情况。
但是由于某些原因(也许是我不明白应该做什么)，回调 autocomplete(..) 在我加载页面时仅执行一次(并正确自动完成中的值) NAMES)，但在文本框中输入时绝不会。
search.html
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/jquery-ui.js"></script>
</head>
{{ form.autocomp.label }}: {{ form.autocomp }}
<script>
$(function() {
$.ajax({
url: '{{ url_for("autocomplete") }}'
}).done(function (data) {
$('#autocomplete').autocomplete({
source: data,
minLength: 2
});
});
});
</script>
application.py
from flask import Flask, Response, render_template, request
import json
app = Flask(__name__)
import wtforms as wt
from wtforms import TextField, Form
NAMES=["abc","abcd","abcde","abcdef"]
class SearchForm(Form):
autocomp= TextField('autocomp',id='autocomplete')
@app.route('/autocomplete',methods=['GET'])
def autocomplete():
search = request.args.get('term')
app.logger.debug(search)
return Response(json.dumps(NAMES), mimetype='application/json')
@app.route('/',methods=['GET','POST'])
def index():
form = SearchForm(request.form)
return render_template("search.html",form=form)
if __name__ == '__main__':
app.run(debug=True)
最佳答案
试试这个
from flask import jsonify
NAMES=["abc","abcd","abcde","abcdef"]
@app.route('/autocomplete',methods=['GET'])
def autocomplete():
search = request.args.get('term')
app.logger.debug(search)
return jsonify(json_list=NAMES)
在 Jquery 中:
<script>
$(function() {
$.ajax({
url: '{{ url_for("autocomplete") }}'
}).done(function (data) {
$('#autocomplete').autocomplete({
source: data.json_list,
minLength: 2
});
});
});
</script>
