javascript - 从设计器视图调用文本的函数和存储值完成

Question

我创建了这几个函数以从文本确认中检索值，但是当我按下 Enter 时它没有调用？无论如何我可以调用这个函数

适应文本确认.js

function(ComponentView, Adapt) {
var TextConfirmation = ComponentView.extend({
     events: {
        'click [type="checkbox"]': 'onConfirmation',
        'keyup .component-item input':'onKeyPress'
        //This is new Code
}


onKeyPress: function(event) {
        if (event.which !== 13) return;
        //<ENTER> keypress
        this.getDatabaselink(event);
              //This is new Method
    },

    getDatabaselink: function() {
        datalink = Adapt.course.get('_globals')._components._textConfirmation.Database
        console.log("datalink "+ datalink)
          //This is new Method
    },

属性.schema

"Database": {
  "type": "string",
  "required": true,
  "default": "",
  "inputType": "Text",
  "validators": [],
  "help": "This is the label for Database link",

}
