Data-set
A powerfull dataset class
Features:
- load data from array, json or html markup
- sort per multiple columns
- complex filters (text, numerical and RegExp)
- define your own filters
- filter per multiple columns
- pagination
- framework agnostic (except for the html markup loader that uses jQuery)
- Unit Tested
data-set has 3 main components, the core, the filters and the data loaders. Filters and data loaders are optional and don't need to be included
Getting Started
npm install javascript-data-set
or download the latest versioninclude either
dist/data-set-complete.min.js
use it ...
Example Usage
Take a look at our jsfiddle page and play with it
Data Loader
The data loader is actually a factory that will return a properly configured and populated dataset
Json
The json loader can load data from a Json object or string. I will configure the dataset columns based on the object properties The Json should contain an array of objects
var dataset, data;
data = [ { col1: 1, col2: 2 }, { col1: 3, col2: 4 } ];
dataset = new Francodacosta.DataSet.Loader.Json(JSON.stringify(data)).load();
Array
The json loader can load data from an array.
Optionally you can specify if the first row contains column
information
The array array should contain one array per row,
var d, data, firstRowHeaders;
data = [['col1', 'col2'], [1, 2], [3, 4]];
dataset = new Francodacosta.DataSet.Loader.Array(data, firstRowHeaders = true).load();
// in this case the first row (['col1', 'col2']) will be discarded and used as column names
Markup
This will load data from an HTML table
<table>
<thead>
<tr>
<!-- it data-name attribute is present, then it will be used for the column name -->
<th data-name="col1">Column 1</th>
<th>Col1</th>
</tr>
</thead>
<tbody>
<tr>
<td>1</td>
<td>2</td>
</tr>
<tr>
<td>3</td>
<td>4</td>
</tr>
</tbody>
</table>
You can load data from this table in the following way
// Please note that this loader requires jQuery
dataset = new window.Francodacosta.DataSet.Loader.Markup('table').load();
Sorting
You can sort by any column and you can specify multiple columns
// sort colum 1 ascending and then by column 2 descending
dataset.setSorting('column 1');
dataset.setSorting('column 2', 'DESC');
// remove all sorting specifications
dataset.clearSorting();
data = dataset.getData()
Filters
A filter is just a function that accepts two arguments, the value and the searchTerm and returns true
if a match is found
The filter is executed for each row
For your convenience a set of standard filters are included
Text Filter
window.Francodacosta.DataSet.Filter.Text.
- match() returns true if there is an exact match
- beginsWith() returns true if the value starts with searchTerm
- endsWith() returns true if the value ends with searchTerm
- contains returns true if the value contains searchTerm
- regularExpression if you need more flexibility you can write your own regular expression
Number Filter
window.Francodacosta.DataSet.Filter.Number.
- equal()
- notEqual()
- greaterThan()
- greaterThanOrEqualTo()
- lessThan()
- lessThanOrEqualTo()
You can add more than one filter, in this case an and
search will be performed
