数据追加两次只是调用单个事件

Question

我正在创建递归数据集。我几乎完成了它，但是当我在选项内添加问题时，嵌套子项面临一个问题，因此如果我添加索引3，它的添加时间应该是两次，因此它会自动添加另外两个索引4和5。添加嵌套问题和嵌套选项。我正在使用avgrund插件进行弹出。

var ParentIndex = 1;
var QuestionIndex = 1;
var OptionIndex = 1;
var Question = {};
var Model = null;

$(function(){
    'use strict';
    $('body').on('click','[data-type=OQ]',function(){
        $(this).CreateQuestion();
    });
    $('body').on('click','[data-type=OPO]',function(){
        $(this).CreateOption();
    });
});
$.fn.extend({
        CreateQuestion: function(){
            var Parent = parseInt($(this).attr('data-parent'));
            Parent = isNaN(Parent) ? null : Parent;

            Model = $(this).avgrund({
             height: 500,
             holderClass: 'custom',
             closeByEscape: true,
             closeByDocument: true,
             showClose: true,
             showCloseText: 'x',

您可以尝试使用取消绑定和绑定点击功能

$('body').unbind('click).bind('click','a[data-type=ADQ]',function(){

});
