将jinjia2后端传到前端的字典数据转化为json
后端代码
from flask import Flask, render_template, jsonify
app = 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>
