Why does not see id?

Question

JavaScript

I have js file in script.
HTML

<div>
    <script type="text/javascript">
      window.onload = function () {
      new Vue({
        		el: "#cheapestsites",
        		data: {
          			cheapsites: []
        		},
        		mounted(){
          			fetch("http://danya.loc/all.json").then(c => c.json()).then((data) => {
           				 this.cheapsites = data;
          			})
        		}
      		});
      		new Vue({
  				src: "./all.json",
  				el: "#one",
  				data: {
    	  			short: "As a rule, most people prefer to buy gadgets at an early stage of the product's life cycle, so it remains NEW longer. Others prefer to buy a bit later, waiting for any early problems to be worked out. And everyone agrees that buying the right to a significant improvement will make you feel at least a little bitter, because Apple does not know how to signal the product's upgrade when it is sold."
        		}
      		})
      }
    </script>

 	</div>

Why can't the element be seen? Although he stood at the very bottom of the code - there is no result, he put this code in the head, he does not see it at all.

Answer 1

src: "./all.json",
