Answer 1

试试这个：

scanner.addListener('scan', function (content) {
  //console.log(content); //It's work
  //alert(content); //It's work 
  this.text2 = content; // <--- Change to this
  this.setText(content); //send to other functions >>It's not working.
});

在你的元素上：

<some-element>{{text2}}</some-element>
