Stupid jQuery Table Sort

========================



This is a stupid jQuery table sorting plugin. Nothing fancy, nothing really

impressive. Overall, stupidly simple. Requires jQuery 1.7 or newer.



[View the demo here][0]



See the examples directory.



Installation via [npm][2]

-------------------------



    $ npm i stupid-table-plugin



Installation via Bower

----------------------



    $ bower install jquery-stupid-table



Example Usage

-------------



The JS:



    $("table").stupidtable();



The HTML:



    

      

        

          int

          float

          string

        

      

      

        

          15

          -.18

          banana

        

        ...

        ...

        ...



The thead and tbody tags must be used.



Add a `data-sort` attribute of "DATATYPE" to the th elements to make them sortable

by that data type. If you don't want that column to be sortable, just omit the

`data-sort` attribute.



Predefined data types

---------------------



Our aim is to keep this plugin as lightweight as possible. Consequently, the

only predefined datatypes that you can pass to the th elements are



* `int`

* `float`

* `string` (case-sensitive)

* `string-ins` (case-insensitive)



These data types will be sufficient for many simple tables. However, if you need

different data types for sorting, you can easily create your own!



Data with multiple representations/predefined order

---------------------------------------------------



Stupid Table lets you sort a column by computer friendly values while displaying

human friendly values via the `data-sort-value` attribute on a td element. For

example, to sort timestamps (computer friendly) but display pretty formated

dates (human friendly)



    

      

        

          Name

          Birthday

        

      

      

        

          Joe McCullough

          April 25, 1991

        

        

          Clint Dempsey

          March 9, 1983

        

        ...

        ...

        ...



In this example, Stupid Table will sort the Birthday column by the timestamps

provided in the `data-sort-value` attributes of the corresponding tds. Since

timestamps are integers, and that's what we're sorting the column by, we specify

the Birthday column as an `int` column in the `data-sort` value of the column

header.



Default sorting direction

-------------------------



By default, columns will sort ascending. You can specify a column to sort "asc"

or "desc" first.



    

      

        

            float

            ...

        

      

    



Sorting a column on load

------------------------



If you want a specific column to be sorted immediately after

`$table.stupidtable()` is called, you can provide a `data-sort-onload=yes`

attribute.



    

      

        

            float

            ...

        

      

    



Multicolumn sorting

-------------------



A multicolumn sort allows you to define secondary columns to sort by in the

event of a tie with two elements in the sorted column. See [examples/multicolumn-sort.html](https://rawgit.com/joequery/Stupid-Table-Plugin/master/examples/multicolumn-sort.html).

Specify a comma-separated list of th identifiers in a `data-sort-multicolumn`

attribute on a `` element. An identifier can be an integer (which represents

the index of the th element of the multicolumn target) or a string (which

represents the id of the th element of the multicolumn target).



  

    

      

        int

        float

        string

      

    

    

      

        1

        10.0

        a

      

      

        1

        10.0

        a

      



Sorting a column programatically

--------------------------------



After you have called `$("#mytable").stupidtable()`, if you wish to sort a

column without requiring the user to click on it, select the column th and call



    var $table = $("#mytable").stupidtable();

    var $th_to_sort = $table.find("thead th").eq(0);

    $th_to_sort.stupidsort();



    // You can also force a direction.

    $th_to_sort.stupidsort('asc');

    $th_to_sort.stupidsort('desc');



Updating a table cell's value

-----------------------------



If you wish for Stupid Table to respond to changes in the table cell values, you

must explicitely inform Stupid Table to update its cache with the new values. If

you update the table display/sort values without using this mechanism, your

newly updated table **will not sort correctly!**



    /*

     * Suppose $age_td is some td in a table under a column specified as an int

     * column. stupidtable() must already be called for this table.

     */

    $age_td.updateSortVal(23);



Note that this only changes the internal sort value (whether you specified a

`data-sort-value` or not). Use the standard jQuery `.text()` / `.html()` methods

if you wish to change the display values.



Callbacks

---------



To execute a callback function after a table column has been sorted, you can

bind on `aftertablesort`.



    var table = $("table").stupidtable();

    table.bind('aftertablesort', function (event, data) {

        // data.column - the index of the column sorted after a click

        // data.direction - the sorting direction (either asc or desc)

        // data.$th - the th element (in jQuery wrapper)

        // $(this) - this table object



        console.log("The sorting direction: " + data.direction);

        console.log("The column index: " + data.column);

    });



Similarly, to execute a callback before a table column has been sorted, you can

bind on `beforetablesort`.



See the complex_example.html file.



Creating your own data types

----------------------------



Sometimes you don't have control over the HTML produced by the backend. In the

event you need to sort complex data without a `data-sort-value` attribute, you

can create your own data type. Creating your own data type for sorting purposes

is easy as long as you are comfortable using custom functions for sorting.

Consult [Mozilla's Docs][1] if you're not.



Let's create an alphanum datatype for a User ID that takes strings in the form

"D10", "A40", and sorts the column based on the numbers in the string.



    

      

        Name

        Age

        UserID

      

    

    

      

        Joseph McCullough

        20

        D10

      

      

        Justin Edwards

        29

        A40

      

      ...

      ...

      ...



Now we need to specify how the **alphanum** type will be sorted. To do that,

we do the following:



    $("table").stupidtable({

      "alphanum":function(a,b){



        var pattern = "^[A-Z](\\d+)$";

        var re = new RegExp(pattern);



        var aNum = re.exec(a).slice(1);

        var bNum = re.exec(b).slice(1);



        return parseInt(aNum,10) - parseInt(bNum,10);

      }

    });



This extracts the integers from the cell and compares them in the style

that sort functions use.



StupidTable Settings

--------------------



As of 1.1.0 settings have been introduced. Settings are defined like so:



    var $table = $("#mytable");

    $table.stupidtable_settings({

        // Settings for this table specified here

    });

    $table.stupidtable();



Listed below are the available settings.



### will_manually_build_table



(Introduced in verison 1.1.1)



Options:



* `true`

* `false` (default)



By default, every time a column is sorted, stupidtable reads the DOM to extract

all the values from the table. For tables that will not change or for very large

tables, this behavior may be suboptimal.  To modify this behavior, set the

`will_manually_build_table` setting to `true`. However, you will be responsible

for informing stupidtable that the table has been modified by calling

`$table.stupidtable_build()`.



    var $table = $("#mytable");

    $table.stupidtable_settings({

        will_manually_build_table: true

    });

    $table.stupidtable();



    // Make some modification to the table, such as deleting a row

    ...

    ...



    // Since will_manually_build_table is true, we must build the table in order

    // for future sorts to properly handle our modifications.

    $table.stupidtable_build();



### should_redraw



(Introduced in verison 1.1.0)



The `should_redraw` setting allows you to specify a function that determines

whether or not the table should be redrawn after it has been internally sorted.



The `should_redraw` function takes a `sort_info` object as an argument. The

object keys available are:



*  `column` - An array representing the sorted column. Each element of the array is of the form `[sort_val, $tr, index]`

*  `sort_dir` - `"asc"` or `"desc"`

*  `$th` - The jquery object of the `` element that was clicked

*  `th_index` - The index of the `` element that was cliked

*  `$table` - The jquery object of the `` that contains the `` that was clicked

*  `datatype` - The datatype of the column

*  `compare_fn` - The sort/compare function associated with the `` clicked.



**Example**: If you want to prevent stupidtable from redrawing the table if the

column sorted has all identical values, you would do the following:



    var $table = $("#mytable");

    $table.stupidtable_settings({

        should_redraw: function(sort_info){

          var sorted_column = sort_info.column;

          var first_val = sorted_column[0];

          var last_val = sorted_column[sorted_column.length - 1][0];



          // If first and last element of the sorted column are the same, we

          // can assume all elements are the same.

          return sort_info.compare_fn(first_val, last_val) !== 0;

        }

    });

    $table.stupidtable();
