Set the data-sortvalue value dynamically?

[tetsujin1979]

Is it possible to set the "data-sortvalue" value dynamically?
As in, pass in a call to a javascript function, e.g. <td data-sortvalue="textToNumber('Text')">Text</td>
where the textToNumber() function converts text to a value used in sorting?

You can set the data-sortvalue value with JavaScript using the dataset
document.querySelector("#my_table_cell").dataset.sortvalue = "somevalue"
or using jQuery attr
$("#my_table_cell").attr("data-sortvalue","somevalue")

You can also hijack the sort function and write your own sort function not limited to the data-sortvalue attribute

$("#your_table").fancyTable({
	sortFunction: function(a, b, fancyTableObject, rowA, rowB){
		// your custom sort logic
	},
	// more settings
})

Closing this ticket since it is not an fancyTable issue.
