<b>Column Renderers</b>. <br />
A column renderer allows you to define a custom visualization function to each column.
In the next example, you'll see how to:
<ul>
<li>Bold text inside a cell</li>
<li>Create a link based upon data contained in a cell</li>
</ul>
To add a column renderer, you have to define it with the <tt>set_col_renderer()</tt>
method before rendering the OS3Grid.<br />
First of all, we'll bold user nick name, creating this renderer:
<div class="code"><pre>
function bold_render ( txt )
{
return '<strong>' + txt + '</strong>';
}
g.set_col_renderer ( 1, bold_render );
</pre></div>
Then, we have to create the render that will show up a link in the id column, this way:
<div class="code"><pre>
// Create link rendered
function link_render ( id )
{
return '<a href="#' + id + ">' + id + '</a>';
}
g.set_col_renderer ( 0, link_render );
</pre></div>
That's all! The final result is shown below.
<div class="result">
<div id="grid"></div>
<script type="text/javascript">
function bold_render ( txt )
{
return '<span style="color: red; font-weight: bold">' + txt + '</span>';
}
function link_render ( id )
{
return '<a href="#">' + id + '</a>';
}
// Create an OS3Grid instance
var g = new OS3Grid ();
// Grid Headers are the grid column names
g.set_headers ( 'id', 'nick', 'Name', 'Surname', 'Age' );
// If contents is bigger than container, Grid will automatically show scrollbars
g.set_scrollbars ( true );
// The grid will have a solid border (these are CSS attributes)
g.set_border ( 1, "solid", "#cccccc" );
// Now, we add some rows to the grid
g.add_row ( 1, 'fsoft', 'Fabio', 'Rotondo', 33 );
g.add_row ( 2, 'john', 'John', 'Bustone', 31 );
g.add_row ( 3, 'mkey', 'Mark', 'Key', 28 );
g.add_row ( 4, 'jdoe', 'John', 'Doe', 35 );
// Enable sortable rows
g.set_sortable ( true );
g.set_col_type ( 0, "int" );
g.set_col_type ( 4, "int" );
g.set_col_render ( 0, link_render );
g.set_col_render ( 1, bold_render );
// Enable highlight of rows with the mouse
g.set_highlight ( true );
// Enable column resize
g.resize_cols = true;
// Show the grid replacing the original HTML object with the "grid" ID.
g.render ( 'grid' );
