<h1>Buttons example <span>Format output data - export options</span></h1>
|
<div class="info">
|
<p>Buttons has two different methods that can be used to format the data exported differently from the data that is shown in the table: <a href=
|
"outputFormat-orthogonal.html">orthogonal options</a> and formatting functions as shown in this example. They both achieve basically the same thing in different
|
ways: namely modification of the output data.</p>
|
<p>Formatting functions for export buttons are specified by assigning a function to one (or more) of the <code>format</code> object of the
|
<code>exportOptions</code> object. Three formatting functions can be used: <code>header</code>, <code>footer</code> and <code>body</code>. This is the primarily
|
advantage of using formatting functions over orthogonal data - the header and footer can also be formatted using this method (of course orthogonal and this
|
formatting function method can both be used together if you prefer!).</p>
|
<p>This example uses a <code>body</code> formatting function to remove the <code>$</code> and <code>,</code> characters from the final column to make it a numeric
|
value in the output data. Since this is common to all three export buttons used, the function is placed into an object that is reused by each button - simply to
|
save repeating the same code! This is not required, but it can be a useful technique.</p>
