flask和bootstrap交互ajax

python端：


from flask import Flask, render_template
import json
import os
 
app = Flask(__name__)
 
testInfo = {}
 
 
@app.route('/test_post/nn', methods=['GET', 'POST'])  # 路由
def test_post():
    testInfo['name'] = 'xiaoliao'
    testInfo['age'] = '28'
    return json.dumps(testInfo)
 
 
@app.route('/')
def hello_world():
    return 'Hello World!'
 
 
@app.route('/index')
def index():
    return render_template('index.html')
 
 
if __name__=="__main__":
    app.run()

JS端：


<!DOCTYPE html>
<html lang="en">
 
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>echarts</title>
</head>
 
<body>
    <p>数据展示：
        <input type="text" id ="NAME">
        <input type="text" id ="AGE"></p> 
    <p>
        <button id = "btn">点击获取</button>
        <input type="text" id ="NAME2">
        <input type="text" id ="AGE2"></p> 
    
    <script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.js"></script>
	<script>
        $.ajax({
        url: "test_post/nn",
        type: "POST",
        dataType: "json",
        success: function (data) {
            // alert(data.name + ":" + data.age);
            $("#NAME").val(data.name);
            $("#AGE").val(data.age);
            console.log(data)}
 
        })
	</script>
    
 
    <script>
        $(function() {
            // body...
            $("#btn").click(function(){
                $.ajax({
                url: "test_post/nn",
                type: "POST",
                dataType: "json",
                success: function (data) {
                // alert(data.name + ":" + data.age);
                $("#NAME2").val(data.name);
                $("#AGE2").val(data.age);
                console.log(data)}
 
                })
            })
        })
    </script>
 
</body>
 
</html>
