消息框会
消失
，因为代码中调用的是QMessageBox的show方法，该方法并没有保留对它的引用，所以一旦函数返回，它就会被垃圾回收
调用QMessageBox的exec_()代替show方法显示弹窗
box = QMessageBox()
box.setIcon(1)
box.setWindowTitle("温馨提示")
box.setText("运行环境检测ok!")
# 添加按钮，可用中文
yes = box.addButton('确定', QMessageBox.YesRo

思路：设置
一个
定时器，去改变label的可见度，或者到时直接隐藏
定时器时间，默认3s，之后隐藏提示
timecount = 3
def onSure_but(self):
self.timecount = 3
self.timer = QTimer(self)
input_mess = self.inputlineEdit.text()
在这个视图函数中，我们使用Django的`render`函数来渲染
一个
名为`index.html`的模板。
接下来，在你的模板文件`index.html`中，使用以下代码来引入JavaScript代码：
```html
{% extends 'base.html' %}
{% block content %}
<!-- 在这里编写页面内容 -->
{% endblock %}
{% block scripts %}
<script>
alert('欢迎访问我的网站！');
</script>
{% endblock %}
在`scripts`模板块中，我们使用了JavaScript的`alert`函数来
弹出
一个
提示框
，里面包含了欢迎
信息
。
最后，在你的`base.html`模板文件中，定义
一个
名为`scripts`的空块，用于在子模板中插入JavaScript代码：
```html
<!DOCTYPE html>
<title>{% block title %}My Website{% endblock %}</title>
</head>
<header>
<!-- 在这里编写网站头部 -->
</header>
{% block content %}
<!-- 在这里编写页面内容 -->
{% endblock %}
</main>
<footer>
<!-- 在这里编写网站底部 -->
</footer>
{% block scripts %}{% endblock %}
</body>
</html>
这样，当你访问这个视图函数所对应的URL时，就会
弹出
一个
提示框
，里面显示欢迎
信息
。
