vue属性拦截实现双向绑定的实例代码

let obj = {}
let get = ''
Object.defineProperty(obj, 'get', {
 set: function(val) {
 document.getElementById('input').value = val
 document.getElementById('text').innerHTML = val
 }
})
document.getElementById('input').addEventListener('keyup', function(e) {
 obj.get = e.target.value
})
obj.get = 'hello'

  

    
hello world
  
  

  

    
    
{{content}}
