How to obtain user input in a mini program

For components that can obtain user input, you need to use the component's attribute bindchange to synchronize the user's input content to AppService.

<input id="myInput" bindchange="bindChange" />
<checkbox id="myCheckbox" bindchange="bindChange" />
var inputContent = {}

Page({
  data: {
    inputContent: {}
  },
    bindChange: function(e) {
        inputContent[e.currentTarget.id] = e.detail.value
    }
})

bindChange is the change event of the input box. The bindchange provided by WeChat still has minor support issues. Currently, this event can only be triggered by losing focus.
