Answer 1

你忘了再添加 1 个右括号

 $("#" + div_id1).html('<br>' + response.substring(0, 1));
 $("#" + div_id2).html(response.substring(1, 2));

Answer 2

你有一些错别字：

$("#" + div_id1).html('<br>' + response.substring(0, 1)); 
$("#" + div_id2).html(response.substring(1, 2));

添加)关闭.html()。

Answer 3

html()后缺少右括号

success: function (response) {
    $("#" + div_id1).html('<br>' + response.substring(0, 1)); 
    //                                                     ^^
    $("#" + div_id2).html(response.substring(1, 2));
    //                                            ^^
