Question

Dynamic Table Creation in Javascript - Add Row, Remove Row, Toggle Row

Asked by: dtreadway7

I am new to dynamic table creation. This table is simple in concept.

Can add as many tables as nec. Each table can add/delete/toggle rows.

Table row 1): Cell1:Title, Cell2:Min/Max, Cell3:closeTable
Table row 2): Cell1:Content(form), Cell2:min/max, Cell3:move row up or down, Cell4:delete this row
Table row 3): Cell1: "Add Additional row to table" link.

Of course, this object and uses "this" keyword. No "getElementById()" used in this one. I am close but am running into some walls. Major wall: Is my table structure right where I am adding the (dContent). Should I be iterating many different (dContent) objects per row and then append the content to them? Should I remove the (dConetnt) object altogeather and track each row inIndex?

The "onchange" select functions are a separate piece. I am planning appending the forms dynamically as well but, I have that piece under control. So for now just ignore the form behavior inside the rows.

Any help is appreciated.

...Day 2 afer posting. Still nothing. I mean, I am making progress but, it sure would be nice if someone could help speed up the process. Up to this point was fairly easy. If I could use an ID reference it would be even eaiser. But I can't. The tracking of the rowIndex should'nt be nec since I am putting it in a parent object. I should just be able to move/ remove/ hide, the object. I tried some variations of (this.dConent.childNode(getElementByTagName="TR) +rowIndex), and (if(this.dContent.parentNode...) but I am still missing something.  Also, now my hide/show toggle is not workin correctly for the added rows. It will open and close once. This I know is because of how I am repeatedly appending the content back into the (dContent) object. I tried just setting the (dContent) object style to display:none...worked better but it also destroys my table structure and moves the row controls to the bottom. Again, the structure is bad I think.    

Bout to trash it and rewrite with a non Obj (id="id' +i'")..guess I can track the rows (inRowIndex) that way too. It seems awfully long and nasty though, when I am so close.
