后端代码
from flask import Flask, render_template, jsonifyapp = Flask(__name__)@app.route('/')
def index():data = {'key': 'value', 'number': 123}return render_template('index.html', data=data)if __name__ == '__main__':app.run(debug=True)前端代码
使用tojson过滤器即可
<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>JSON Example</title>
</head>
<body><script type="text/javascript">var data = {{ data|tojson }};console.log(data);</script>
</body>
</html>
