我和 konva 一起工作，我有一系列这种类型的正方形

let square= new Konva.Rect({
              x:cur_x,
              y:cur_y,
              width:seg_size,
              height:seg_size,
              stroke:"black",
              fill:"green",
              name:"rect"
          });

我得到它们都是这样的：var s=stage.find(".rect"); 现在，当我点击其中一个方块时，我需要得到它的位置。我这样做

s.on("click",()=>{
   console.log(this.getClientRect().x)
});

但是我得到TypeError: this.getClientRect is not a function. 了如何获取位于数组（组）中的元素？

我想将降价添加到管理面板。在所有降价中，tinymce 有效，但它缺乏添加代码的能力。结果，形成了两个问题： 1.我可以将自己的按钮添加到tinymce吗？如何？2.我找到了admin表单模板，但是这个表单在for中循环。原来符号栏会出现在好几个地方。唯一想到的是通过js添加html和css。

{% extends "admin/base_site.html" %}
{% load i18n admin_urls static admin_modify %}

{% block extrahead %}{{ block.super }}
<script type="text/javascript" src="{% url 'admin:jsi18n' %}"></script>
{{ media }}
{% endblock %}

{% block extrastyle %}{{ block.super }}<link rel="stylesheet" type="text/css" href="{% static "admin/css/forms.css" %}" />{% endblock %}

{% block coltype %}colM{% endblock %}

{% block bodyclass %}{{ block.super }} app-{{ opts.app_label }} model-{{ opts.model_name }} change-form{% endblock %}

{% if not is_popup %}
{% block breadcrumbs %}
<div class="breadcrumbs">
<a href="{% url 'admin:index' %}">{% trans 'Home' %}</a>
&rsaquo; <a href="{% url 'admin:app_list' app_label=opts.app_label %}">{{ opts.app_config.verbose_name }}</a>
&rsaquo; {% if has_change_permission %}<a href="{% url opts|admin_urlname:'changelist' %}">{{ opts.verbose_name_plural|capfirst }}</a>{% else %}{{ opts.verbose_name_plural|capfirst }}{% endif %}
&rsaquo; {% if add %}{% blocktrans with name=opts.verbose_name %}Add {{ name }}{% endblocktrans %}{% else %}{{ original|truncatewords:"18" }}{% endif %}
</div>
{% endblock %}
{% endif %}

{% block content %}<div id="content-main">
{% block object-tools %}
{% if change %}{% if not is_popup %}
  <ul class="object-tools">
    {% block object-tools-items %}
    <li>
        {% url opts|admin_urlname:'history' original.pk|admin_urlquote as history_url %}
        <a href="{% add_preserved_filters history_url %}" class="historylink">{% trans "History" %}</a>
    </li>
    {% if has_absolute_url %}<li><a href="{{ absolute_url }}" class="viewsitelink">{% trans "View on site" %}</a></li>{% endif %}
    {% endblock %}
  </ul>
{% endif %}{% endif %}
{% endblock %}
<form {% if has_file_field %}enctype="multipart/form-data" {% endif %}action="{{ form_url }}" method="post" id="{{ opts.model_name }}_form" novalidate>{% csrf_token %}{% block form_top %}{% endblock %}

{% if is_popup %}<input type="hidden" name="{{ is_popup_var }}" value="1" />{% endif %}

    <p class="errornote">
    {% if errors|length == 1 %}{% trans "Please correct the error below." %}{% else %}{% trans "Please correct the errors below." %}{% endif %}
    </p>
    {{ adminform.form.non_field_errors }}
{% endif %}

{% block field_sets %}

{% for fieldset in adminform %}

  {% include "admin/includes/fieldset.html" %}

{% endfor %}
{% endblock %}

{% block after_field_sets %}{% endblock %}

{% block inline_field_sets %}
{% for inline_admin_formset in inline_admin_formsets %}
    {% include inline_admin_formset.opts.template %}
{% endfor %}
{% endblock %}

{% block after_related_objects %}{% endblock %}

{% block submit_buttons_bottom %}{% submit_row %}{% endblock %}

{% block admin_change_form_document_ready %}
