jquery - Mixitup 插件多能复选框

Question

我想在加载时选中所有复选框，但这并不能正常工作

通常您会添加这段代码，但没有任何效果加载: { filter: '.square,.circle,.triangle' },

请参阅codepen http://codepen.io/anon/pen/GZxwzq

// To keep our code clean and modular, all custom functionality will be contained inside a single object literal called "checkboxFilter".

var checkboxFilter = {
  
  // Declare any variables we will need as properties of the object
  
  $filters: null,
  $reset: null,
  groups: [],
  outputArray: [],
  outputString: '',
  
  // The "init" method will run on document ready and cache any jQuery objects we will need.
  
  init: function(){
    var self = this; // As a best practice, in each method we will asign "this" to the variable "self" so that it remains scope-agnostic. We will use it to refer to the parent "checkboxFilter" object so that we can share methods and properties between all parts of the object.
    
    self.$filters = $('#Filters');
    self.$reset = $('#Reset');
    self.$container = $('#Container');
    
    self.$filters.find('fieldset').each(function(){

    self.$filters.on('change', function(){
      self.parseFilters();

      e.preventDefault();
      self.$filters[0].reset();
      self.parseFilters();

  // The parseFilters method checks which filters are active in each group:
  
  parseFilters: function(){
    var self = this;
 
    // loop through each filter group and add active filters to arrays

一般来说，您不能在加载时分配属性吗？例如，如果我想勾选我可以做的所有方框:

$('.checkbox').prop('checked',true) 

并且任何属于复选框类的内容都将更新为选中状态。在您的函数中，您可能会执行一个在加载时执行此回调的回调。

也可能是当您的 javascript 执行时这些元素没有填充到页面上，因此它假定这些元素不存在，因此对它们不做任何事情。
