Adding iframe to div can realize Ajax function_html/css_WEB-ITnose

Adding an iframe to the div can implement the Ajax function. If you query, for example, city selection, use Ajax to implement it.

In .net, you can consider using UpdatePanel. But when I clicked the query, the originally selected city was cleared.

Using iframe can effectively solve the problem.

<script type="text/javascript">        function searchSupplier(id) {            document.getElementById('iframe1').src = 'supplier_detail.aspx?id=' + id;        }    </script>
