elman

Element Manager

elman is a fast and lightweight pure JavaScript module for generic HTML element sorting and searching. It does not impose any restrictions on how to mutate the controlled structure; instead, it efficiently monitors the structure for changes, allowing you to update it however you normally would (jQuery, document methods etc.).

Usage

npm install elman 

List-like Structures

var ElementManager = require('elman');
var elements = new ElementManager();
 
elements.sync({
   containerId: 'id-of-container', // e.g. id of ul
   elementType: 'li'               // any valid HTML selector
});

Table-like Structures

elements.sync({
   containerId: 'id-of-container', // e.g. id of tbody
   elementType: 'tr',              // any valid HTML selector
   cellType: 'td'                  // any valid HTML selector
});

Note: elementType and cellType should be relatively unique.

The elements object can be re-synced at any time by invoking the sync method again with the new structure's details.

Sorting

// default
elements.sort();
 
// specialised
elements.sort({
   numeric: true,  // defaults to string based sort
   cell: 1         // for table-like structures (column to sort by), defaults to 0
});

Searching

// search all cells
elements.search({
   term: searchTerm
});
 
// search specific cells
elements.search({
   term: searchTerm,
   cells: [1,3,5]
});
 
// clear search affects
elements.clearSearch();

Mutating

After a value within the synced structure has been changed, simply call the mutated() method and elman will resync the values on the next sort or search invocation. Alternatively, you can set a threshold value to indicate the number of mutations that should occur before the structure is immediately resynchronised.

For example, assume you want to increment the .click-count cell in a table. The following would immidiately resync your elman object on the 10th incrementation (if neither sort or search were called in between).

$('tr').click(function() {
   var rowClicks = $(this).find('.click-count'),
       currTotal = parseInt(rowClicks.text());
 
   rowClicks.text(currTotal + 1);
 
   elements.mutated({
      threshold: 10
   });
});
