django admin 根据choice字段选择的不同来显示不同的页面方式

tip/tip.js
    var react = function () {
    if (django.jQuery('#id_tiptype').val() == 'content') {
      django.jQuery('#id_content').parent().parent().show(500);

      django.jQuery('#id_cropping').parent().parent().hide(500);

      django.jQuery('#id_image').parent().parent().show(500);
      django.jQuery('#id_cropping').parent().parent().show(500);
    }
    };

    #当选择的类型改变的时候触发react函数
    django.jQuery(function () {
      react();
      django.jQuery('#id_tiptype').on('change', react);
