javascript - 未捕获的异常错误 "Illegal operation on WrappedNative prototype object"

Question

是否知道为什么以下 javascript/jquery 代码可能会产生错误消息: 未捕获的异常:[异常...“对 WrappedNative 原型(prototype)对象进行非法操作”]？

代码:

function deletereceipt(id){
 var $delconfdialog = $('<div id="dialog-confirm"></div')
                       .html('Are you sure you want to delete this receipt?')
                       .dialog({
                          autoOpen: true,
                          title: 'Delete Confirmation',
                          buttons: {
                             "Delete": function(){
                                $.post('Receipt.py',{'cm':'Delete','receiptid': obj},function(){
                                   $('#receiptrow'+id).remove();
                                });
                                $(this).dialog('close');
                             },
                             "Cancel" :function(){
                                $(this).dialog('close');   
                             }
                          }
                       });
    }

您在这里违反了基本的 OOP 原则:您将方法与其分离 对象。
