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.
