Question

Here is webtoolkit but …

var t = new SortableTable(document.getElementById('myTable'), 100);

2 parameters

function SortableTable (tableEl) {

and where is height ?

Here is my try to make it work but it doesn’t works (only commented code works but for ff and ie only)

    function ScrollableTable(tableEl, tableHeight, tableWidth) 
{
    this.tbody = tableEl.getElementsByTagName('tbody');
    this.thead = tableEl.getElementsByTagName('thead');
    this.tfoot = tableEl.getElementsByTagName('tfoot');

    this.getInnerText = function(el) {
        if (typeof (el.textContent) != 'undefined') return el.textContent;
        if (typeof (el.innerText) != 'undefined') return el.innerText;
        if (typeof (el.innerHTML) == 'string') return el.innerHTML.replace(/<[^<>]+>/g, '');
    }

    this.getParent = function(el, pTagName) {
        if (el == null) return null;
        else if (el.nodeType == 1 && el.tagName.toLowerCase() == pTagName.toLowerCase())
            return el;
        else
            return this.getParent(el.parentNode, pTagName);
    }

    this.sort = function(cell) {

        var column = cell.cellIndex;
        var itm = this.getInnerText(this.tbody[0].rows[1].cells[column]);
        var sortfn = this.sortCaseInsensitive;

        if (itm.match(/\d\d[-]+\d\d[-]+\d\d\d\d/)) sortfn = this.sortDate; // date format mm-dd-yyyy
        if (itm.replace(/^\s+|\s+$/g, "").match(/^[\d\.]+$/)) sortfn = this.sortNumeric;

        this.sortColumnIndex = column;

        var newRows = new Array();
        for (j = 0; j < this.tbody[0].rows.length; j++) {
            newRows[j] = this.tbody[0].rows[j];
        }

        newRows.sort(sortfn);

        if (cell.getAttribute("sortdir") == 'down') {
            newRows.reverse();
            cell.setAttribute('sortdir', 'up');
        } else {

        }

    </asp:GridView>
</asp:Panel>

Is there some wais to make this script works for GridView ?..

and Ive got a trouble with hiding of vertical scrollbar if there is horizontal scroll bar (but that’s trouble if I use commented code)

Answer 1

Couldn’t you just have a new function that instantiates a new SortableTable? Or do you have to rewrite everything for some reason?

Something like:

function ScrollableTable(tableEl, tableHeight, tableWidth) 
{
var table = new SortableTable(document.getElementById('myTable'), 100);
do stuff to the table that you whant..like width and height..
}
