WeChat Mini Program-----Generally obtain the value of the input box

In the WeChat applet, you can obtain the value of the input box through the following steps:

1. In WXML, create an input box using tags and set a unique id attribute.

```html
<input id="myInput" bindinput="inputChange" />
```

2. In JS, define an event handling function to obtain the value of the input box.

```javascript
Page({
  inputChange: function(e) {
    var inputValue = e.detail.value;
    console.log(inputValue);
  }
})
```

3. In the event processing function, obtain the value of the input box through e.detail.value and perform corresponding processing. This can be stored in a data object or otherwise manipulated.

Through the above steps, you can obtain the value of the input box in the WeChat applet and perform subsequent operations.
