or install the npm package:

# To get the latest stable version, use npm from the command line.

Usage

First, load jQuery, jQuery UI, and the plugin:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js" type="text/javascript" charset="utf-8"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js" type="text/javascript" charset="utf-8"></script>
<script src="js/structured-filter.js" type="text/javascript" charset="utf-8"></script>

The widget requires a jQuery UI theme to be present, as well as its own included base CSS file (structured-filter.css). Here we use the "ui-lightness" theme as an example:

<link rel="stylesheet" type="text/css" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/themes/ui-lightness/jquery-ui.css">
<link href="css/structured-filter.css" rel="stylesheet" type="text/css">

Now, let's attach it to an existing <div> tag:

<script type="text/javascript">
    $(document).ready(function() {
        $("#myFilter").structFilter({
            fields: [
                {id:"lastname", type:"text", label:"Lastname"},
                {id:"firstname", type:"text", label:"Firstname"},
                {id:"active", type:"boolean", label:"Is active"},
                {id:"age", type:"number", label:"Age"},
                {id:"bday", type:"date", label:"Birthday"},
                {id:"category", type:"list", label:"Category",
                    list:[
                        {id:'1', label:"Family"},
                        {id:'2', label:"Friends"},
                        {id:'3', label:"Business"},
                        {id:'4', label:"Acquaintances"},
                        {id:'5', label:"Other"}
                    ]
                }
            ]
        });
    });
</script>

<div id="myFilter"></div>

This will change the <div> into the widget.

Model

The widget is configured with a list of fields to use in the search conditions.

Fields

Each field must have an ID, a type, and a label.

Fields of type "list" must also have a "list" property for the values (array of objects with id and label).

Example:

fields = [
    {id:"lastname", type:"text", label:"Lastname"},
    {id:"firstname", type:"text", label:"Firstname"},
    {id:"active", type:"boolean", label:"Is active"},
    {id:"age", type:"number", label:"Age"},
    {id:"bday", type:"date", label:"Birthday"},
    {id:"category", type:"list", label:"Category",
        list:[
            {id:'1', label:"Family"},
            {id:'2', label:"Friends"},
            ...
        ]
    }
];

Note: To change the behavior of a "list" field, use the type "list-options" and "list-dropdown" instead of "list".

Conditions

Queries are expressed as a set of conditions.

Each condition is defined by: - a field - an operator - one or several values

For each field the possible operators are determined by it's type.

boolean:

date:

list:

number:

text:

time:

Options

structured-filter provides several options to customize its behaviour:

buttonLabels (Boolean)

$("#myFilter").structFilter({
    buttonLabels: true
});

Defaults to false.

dateFormat (String)

Common formats are: Default - "mm/dd/yy", ISO 8601 - "yy-mm-dd", Short - "d M, y", Medium - "d MM, y", Full - "DD, d MM, yy". For a full list of the possible formats see the jQuery formatDate function.
