List API





Using List.js is pretty much plug and play, but you can change some options if you feel like it.

new List(id/element, options, values);
  • id or element *required Id the element in which the list area should be initialized. OR the actual element itself.
  • options Some of the option parameters are required at some times

    • valueNames Array, default: null. *required
      If the list contains items on initialization, then this array has to contain the value names (class names) for the different values of each list item.

      <ul class="list">
              <span class="name">Jonny</span>
              <span class="city">Sundsvall</span>
      var valueNames = ['name', 'city'];
      <ul class="list">
       <li data-id="1">
         <a href="" class="link name">Jonny</a>
         <p class="born timestamp" data-timestamp="1234">1986</p>
         <img class="image" src="javve.jpg" />
      var valueNames =  [
        { data: ['id'] },
        { name: 'timestamp', attr: 'data-timestamp' },
        { name: 'link', attr: 'href' },
        { name: 'image', attr: 'src' }
    • item String, default: undefined
      ID to item template element or a string of HTML.

      var options = {
          item: "<li><span class='name'></span><span class='city'></span></li>"
      // or
      var options = {
          item: 'cool-item-id'
    • listClass String, default: "list"
      What is the class of the list-container?

    • searchClass String, default: "search"
      What is the class of the search field?

    • sortClass String, default: "sort"
      What is the class of the sort buttons?

    • indexAsync Boolean, default: false
      If there are already items in the list to which the List.js-script is added, then should the indexing be done in a asynchronous way? Good for large lists (> 500 items).

    • page Int, default: 200
      Defines how many items that should be visible at the same time. This affects performance.

    • i Int, default: 1
      Which item should be shown as the first one.

    • pagination Boolean, default: false
      Read more here.

  • values Array of objects) (*optional Values to add to the list on initialization.


  • listContainer Element
    The element node that contains the entire list area.

  • list Element
    The element containing all items.

  • items Array
    An Array of all Item-objects in the list.

  • visibleItems Array
    The currently visible items in the list

  • matchingItems Array
    The items matching the currently active filter and search.

  • searched Boolean
    Returns true if the list is searched.

  • filtered Boolean
    Returns true if there is an active filter.


  • add(values, callback)
    Adds one or more items to the list.

    listObj.add({ name: "Jonny", city: "Stockholm" });
    { name: "Gustaf", city: "Sundsvall" }
    , { name: "Jonas", city: "Berlin" }

    If callback is set then items are added to the list in a asynchronous way, and the callback is called when all items are added. This is especially useful when adding very many items (200+ or something), or if you just like the asynchronous coding style.

    listObj.add(arrayWithManyManyItems, function(items) {
    console.log('All ' + items.length + ' were added!');
  • remove(valueName, value)
    Removes items from the list where the value named valueName has value value. Returns the number of items that where removed.

    itemsInList = [
    { id: 1, name: "Jonny" }
    , { id: 2, name "Gustaf" }
    listObj.remove("id", 1); // return 1
  • get(valueName, value)
    Returns values from the list where the value named valueName has value value.

    itemsInList = [
    { id: 1, name: "Jonny" }
    , { id: 2, name "Gustaf" }
    listObj.get("id", 2); // return { id: 2, name "Gustaf" }
  • sort(valueName, {
      order: 'desc',
      alphabet: undefined,
      insensitive: true,
      sortFunction: undefined

    Sorts the list based on values the in the column named valueName. The alphabet option is used when you have non-english alphabet where which JavaScript don't know how to sort some characters by default.

    The default sort function is found here, if you want to use your own, read the code and check out the tests.

    listObj.sort('name', { order: "asc" }); // Sorts the list in abc-order based on names
    listObj.sort('name', { order: "desc" }); // Sorts the list in zxy-order based on names
    // Sort swedish characters correcly, case-insensitive.
    listObj.sort('name', { alphabet: "ABCDEFGHIJKLMNOPQRSTUVXYZÅÄÖabcdefghijklmnopqrstuvxyzåäö" });
    // Sort swedish characters correcly, case-sensitive.
    listObj.sort('name', { alphabet: "AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvXxYyZzÅåÄäÖö" });
    // Alphabet could also be on the actual listObj via
    listObj.alphabet = "AaBbCcDdEeFfGgHhIiJjKkLlMmNnOoPpQqRrSsTtUuVvXxYyZzÅåÄäÖö";
  • search(searchString, columns)
    Searches the list

    itemsInList = [
    { id: 1, name: "Jonny" }
    , { id: 2, name "Gustaf" }
    , { id: 3, name "Jonas" }
    ];'Jonny'); // Only item with name Jonny is shown (also returns this item); // Show all items in list'Jonny', ['name']); // Only search in the 'name' column
  • clear()
    Removes all items from the list

  • filter(filterFunction)

    itemsInList = [
    { id: 1, name: "Jonny" }
    , { id: 2, name "Gustaf" }
    , { id: 3, name "Jonas" }
    listObj.filter(function(item) {
    if (item.values().id > 1) {
       return true;
    } else {
       return false;
    }); // Only items with id > 1 are shown in list
    listObj.filter(); // Remove all filters
  • size()
    Returns the size of the list.

  • show(i, page)
    Shows page number of items from i. Use for paging etc.

    itemsInList = [
    { id: 1, name: "Jonny" }
    , { id: 2, name "Gustaf" }
    , { id: 3, name "Jonas" }
    , { id: 4, name "Egon" }
    , { id: 5, name "Frank" }
    , { id: 6, name "Ester" }
    ];, 3); // Display item 4,5,6 
  • update()
    Updates the current state of the list. Meaning that if you for instance hides some items with the itemObj.hide() method then you have to call listObj.update() if you want the paging to update.

  • reIndex()
    Re-index list from HTML. Good to use if the HTML has been changed by something else than List.js.

  • fuzzySearch()

  • on(event, callback)
