在v1.0版本中实现了"页面点击按钮,生成对应测试数据"的功能,但是在操作页面只有一个按钮,没有提供任何参数(即没有涉及到参数在前后端传递,只是单纯的触发请求);
这次在前端页面给每个按钮加一个参数,用来控制生成测试数据的个数,更改后的页面大概如下
所以接下来要做如下改造工作:
- 改造html模版,在每个按钮后添加一个输入框(添加input标签);
- 改造视图函数,例如phone()函数,使它能够接收一个参数,控制生成数据的个数;
- 改造js代码,使它能够接收input标签输入的值;
一、修改 base.html 和 base.css
为每个按钮添加一个输入框,另外调整下整体布局,base.html 代码如下
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>Title</title> 6 <link rel="stylesheet" href="{{ url_for('static', filename='base.css') }}" type="text/css"> 7 <script type="text/javascript" src="{{ url_for('static', filename='jquery-3.5.1.js') }}"></script> 8 </head> 9 <body> 10 <div class="left"> 11 <div class="b1"> 12 <form method="get" action=""> 13 <button type="button" id="b01">手机号码</button> 14 <label> 15 <input type="text" name="phone_num" id="pnone_num" value="" placeholder="请输入个数"> 16 </label> 17 </form> 18 19 </div> 20 21 <div class="b1"> 22 <form method="get" action=""> 23 <button type="button" id="b02">身份证ID</button> 24 <label> 25 <input type="text" name="card_id" id="id_num" value="" placeholder="请输入个数"> 26 </label> 27 </form> 28 </div> 29 30 <div class="b1"><button type="button" id="b03">人名</button> 31 <label> 32 <input type="text" name="name" value="" placeholder="请输入个数"> 33 </label> 34 </div> 35 <div class="b1"><button type="button" id="b04">一段文字</button></div> 36 <div class="b1"><button type="button" id="b05">特殊字符</button> 37 <label for=""><select name="special" id="select"> 38 <option value="5">5个</option> 39 <option value="10">10个</option> 40 <option value="20">20个</option> 41 </select></label> 42 </div> 43 44 <div class="b1"><button style="background-color:darkred;color: #fcfcfc" type="button" id="b07">清空输出</button></div> 45 </div> 46 47 <div ><label for="result"></label><textarea class="textera" name="" id="result" cols="103" rows="20"></textarea></div> 48 49 50 </body> 51 </html>View Code
base.css代码如下
.b1 { /*float: left;*/ /*display: inline;*/ /*background-color: #7ED321;*/ margin-right: 20px; margin-left: 50px; margin-top: 20px; } div .left { float:left; color: #f00; border: 2px; } input .w { width: 1px; } .textera { position:absolute; left: 350px; top: 20px; background-color: #f1f1d1; }
二、改造视图函数
因为之前当触发按钮时,触发的get请求如下
http://127.0.0.1:5000/phone
现在要加一个参数,假设参数名为num,希望触发的get请求变为如下形式
http://127.0.0.1:5000/phone?num=
后台路由如果想接收这种形式的参数,例如上面的num,则可以通过下面这种方式
request.args.get("num")
以phone()视图函数为例,改造后如下
def create_phone(num): """生成电话""" phones = [fake.phone_number() for _ in range(int(num))] return " ".join(phones) @app.route('/phone', methods=['POST', 'GET']) def phone(): num = request.args.get("num") if num == "": # 如果接收到的num为空,则默认传5 data = create_phone(5) else: data = create_phone(num) return data
三、改造js代码,使它能够接收input标签输入的值
在实现过程中,一直在想如何从前端获取input标签输入的num参数值,传递给后端路由
经过多方查找资料,还是从jquery入手,可以先用js获取input标签的值,再拼接到url中,如下
$(document).ready(function(){ $("#b01").click(function(){ var num = $('input[name=phone_num]').val() // 获取phone输入框的值 console.log(num) htmlobj=$.ajax({url:"http://10.237.4.83:5000/phone?num="+num,async:false}); // 把参数num的值拼接到url中 $("#result").html(htmlobj.responseText); }); });
最后看一下实现效果:
综上,代码改造全部完成,完整代码如下:
