如何在表格单元格中插入输入字段？

Question

Sorry for the noob question: I want to create a table with input fields where the can add new ones, if they are needed. But I can'T figure out how add another input field inside a cell where another input field already exists.

My code is:

var par=obj.parentNode;
while(par.nodeName.toLowerCase()!='tr')
{ par=par.parentNode; }
// this gives me the index of the row.. works fine.

cell1=document.getElementById('avz_tabelle').rows[par.rowIndex].cells;
// this puts the content of the cells into the array "cell1"

var feld = cell1[1].createElement("input"); 
feld.setAttribute("name","avz_keywords" + avz_array + "[]"); 
feld.setAttribute("onblur","");
feld.setAttribute("type","text"); 
feld.setAttribute("size","30"); 
// Now I create a input element
// And now comes the problem:

cell1[1].appendChild(feld); // --> doesn't work

Has anyone a suggestion for me? I got the idea to work without a table, theoratically that would work with my way. But that wouldn't be satisfying :/

Answer 1

If you look in a debugging console, you should see something like

TypeError: Object #<HTMLDivElement> has no method 'createElement'

Instead of creating the element from cell1[1] , use document.createElement()

 var feld = document.createElement("input");

Answer 2

You should use document.createElement("input"); instead of cell1[1].createElement("input");

As always (and as also stated in another answer here), the JavaScript console should be the first place to look for hints on what the problem is!

And wouldn't it actually be much easier if each table cell you want to add values to got a separate ID? Something containing perhaps the row index and the column index ... Then you could just select it directly.
