nextSibling issues

Ok, this has been killing me all night, I mean I've been working on this code for atleast 8 hours now. What is the problem with this, argggg.

I am trying to update all <span id="column_[row index number]_[column index number]_[layout position number]"> to increment开发者_JAVA技巧 it by one up until the next id="row_[row index number]" tr element, The tr elements that it should be searching in has an id of tr_[row index number]_[column index number]_[layout position number] but for some god knows what reason, it gives me issues. It's updating the same <span> tag 2x, and this changes it from the desired value to 1 more than it should be... There's only 1 <span> tag within the firstChild <td> element of each of the <tr> elements. I just don't understand why it is setting it 2x for just 1 of them, and it seems that it's random or something. argggg.

There's only 1 <span> element in the <td id="tdcolumn_[row index number]_[column index number]_[layout position number]> tag, but for some reason, it is calling the same tag twice. It should only call it once. arggg. I don't understand why??

Here's my code someone please help me here...

// Reorder all columns, if any, in the other rows after this 1.
if (aRowId != 0 && lId.indexOf("tr_" + aRowId) == 0 && rowComplete != aRowId)
{
    var tempTr = lTable.childNodes[i].childNodes[p];


    while(tempTr.nodeType == 1 && tempTr.nextSibling != null)
    {
        var tempId = tempTr.getAttribute("id");

        if (!tempId) continue;

        if (tempId.indexOf("row_") == 0)
        {
            // All done this row, set it to completed!
            rowComplete = aRowId;
            break;
        }

        if (tempTr.hasChildNodes)
        {

            var doneChilds = false;

            // grab the id where tdcolumn_{aRowId}.indexOf = 0.
            for (fcTd = 0; fcTd<tempTr.childNodes.length; fcTd++)
            {
                if (tempTr.childNodes[fcTd].nodeName == '#text') continue;

                var tempfcId = tempTr.childNodes[fcTd].getAttribute("id");

                if (!tempfcId) continue;

                if (tempfcId.indexOf("tdcolumn_" + aRowId) != 0) continue;

                // looping through the children in the <td> element here.
                if (tempTr.childNodes[fcTd].hasChildNodes)
                {
                    for (x = tempTr.childNodes[fcTd].childNodes.length-1; x>0; x--)
                    {
                        if (tempTr.childNodes[fcTd].childNodes[x].nodeName == '#text') continue;

                        var tempSpanId = tempTr.childNodes[fcTd].childNodes[x].getAttribute("id");

                        if (!tempSpanId) continue;

                        if (tempSpanId.indexOf("column_") != 0) 
                            continue;

                        // alert(tempSpanId);

                        alert(tempTr.childNodes[fcTd].childNodes[x].nodeName);

                        var tSpanId = new Array();
                        tSpanId = tempSpanId.split("_");

                        if (currColumnId == 0)
                        {
                            currColumnId = parseInt(tSpanId[1]);
                            var incCol = currColumnId;  
                        }

                        incCol++;

                        // alert("currColumnId = " + currColumnId + "\n\ntSpanId[1] = " + tSpanId[1] + "\n\nincCol = " + incCol);

                        // Set the new Id's and Text, after which we can exit the for loop.
                        tempTr.childNodes[fcTd].childNodes[x].setAttribute("id", "column_" + incCol);
                        tempTr.childNodes[fcTd].childNodes[x].setAttribute("class", "dp_edit_column");
                        tempTr.childNodes[fcTd].childNodes[x].innerHTML = oColumnText + " " + incCol;
                        // tempTr.childNodes[fcTd].setAttribute("id", "tdcolumn_" + aRowId + "_" + (parseInt(tSpanId[1])+1) + "_" + tSpanId[3]);

                        doneChilds = true;

                        break;
                    }
                }
                else
                    continue;

                if (doneChilds == true)
                    continue;
            }
        }
        else
            continue;

        tempTr = tempTr.nextSibling;
    }
}

Please help me, Thank You :)

Though I don't think I can solve your problem without the relevant HTML parts, I see at least one error in your code:

if (doneChilds = true)

This always evaluates to true. It should read:

if (doneChilds)

BTW, you don't need getAttribute here:

var tempfcId = tempTr.childNodes[fcTd].getAttribute("id");

Just use:

var tempfcId = tempTr.childNodes[fcTd].id;

Never set a class name using setAttribute, like here:

tempTr.childNodes[fcTd].childNodes[x].setAttribute("class", "dp_edit_column");

Use:

tempTr.childNodes[fcTd].childNodes[x].className = "dp_edit_column";

(the same is true for the line above that one, setting the id of an element).
