使jquery默认崩溃

Question

我有phpbb 3.1论坛。 我有一个-jquery.collapse.js。 我希望这种侮辱会被打开。 小麦参数我需要改变吗？ 并且可以使它默认只有1是开放而不是关闭？ 默认将是第一个打开的类别，当我打开下一个类别时，打开的类别将自动关闭。

代码 -

(function($, exports) {

  // Constructor
  function Collapse (el, options) {
    options = options || {};
    var _this = this,
      query = options.query || "> :even";

      $el: el,
      options : options,
      sections: [],
      isAccordion : options.accordion || false,
      db : options.persist ? jQueryCollapseStorage(el.get(0).id) : false
    });

    // Figure out what sections are open if storage is used
    _this.states = _this.db ? _this.db.read() : [];

    // For every pair of elements in given
    // element, create a section
    _this.$el.find(query).each(function() {
      new jQueryCollapseSection($(this), _this);

    // Capute ALL the clicks!
    (function(scope) {
      _this.$el.on("click", "[data-collapse-summary] " + (scope.options.clickQuery || ""),

  //jQuery DOM Ready

  // Expose constructor to
