Get value of attribute

Get value of attribute

Hello all,

I have an application in which each column has to be formatted differently. I use render in the following way:

columnDefs: [
    {
        targets: "_all",
        render: function (data) {
                return window[?????](data);
        }
    }
],

On the position of the questionmarks i would like to have the value of an attribute; data-??? (the name doesnt really matter)
What attribute can I use for this?

Even better would be to have:

<th data-render="function"></th>

Is there any way to do this?

Thanks

    Hi @StijnQCA ,

    Not sure if this what you're looking for, but you can give each column a unique class with columns.className. That would allow you to then set CSS formatting rules for each.

    Hope that helps,

    Cheers,

    Hey @colin

    Thanks for the quick reply.

    I want to use a function for each column that formats the cell in a specific way.
    For example the status column should be formatted like:

    function formatStatus(data) {
        return '<span class="label label-' + data.style + '">' + data.value + '</span>'
    }
    

    Unfortunately this is not achieved by setting the columns.className| Option.

    Hi StijnQCA, I think that you may want to use the created row callback and then apply a class to the cell. Say your column is in the 4th position.

     "createdRow": function (row, data, index) {
           var style = data.style
           $('td', row).eq(4).addClass(style);
    });
    

    I don't know if this can work I haven't tested it.

    Hi again,

    Yep, that's just for the CSS class. If you want to do more, and change how it looks, you can use columns.render, and the display option. Take a look at this example - it changes the column into a URL and truncates with ellipses.

    Hope that's the one you're after!

    Cheers,

    I ended up adding the value to the data object like:

    {
        targets: "_all",
        render: function (data) {
            return window[data.formatter](data);
        }
    }
    

    this way the formatter used depends on what is retrieved from the server.
