动态生成的div id相同?

Question

or(var i=0;i<3;i++){

                console.log(i)
                creatDiv(i); 
                   
            }

function creatDiv(item){

<span id="div'+ item +'" class="personId"></span>

}
为何为何打印出span的id均是div0

Answer 1

function&nbsp;creatDiv(id){&nbsp;&nbsp;&nbsp;&nbsp;return&nbsp;`<span&nbsp;id="${id}"&nbsp;class="personId"></span>` }

Answer 2

var i 换成let i
