     </text>
        )
        
})

<div id="grid">   </div>

推荐答案

（' 。delete-book'）。live（' click'， function （）{

('.delete-book').live('click', function () {

.getJSON（' / Methods / GetBook /' +

.getJSON('/Methods/GetBook/' +

（ this ）。attr（' id'）， function （data）{
var book = data;

(this).attr('id'), function (data) { var book = data;
