获取子元素html的id

Question

I have javascript code like this:

<tr id='$stavkaid'>
    <td class='nonEditableData'>$naziv</td>
    <td contenteditable='true' class='editableData' onkeypress='return (event.charCode == 8 || event.charCode == 0 || event.charCode == 13 || event.charCode == 46) ? null : event.charCode >= 48 && event.charCode <= 57' onblur='if(innerHTML.length <= 0) { innerHTML = 0 }else{ innerHTML = innerHTML, checkInput(parentNode.id)}'>$kolicina</td>
    <td contenteditable='true' class='editableData' onkeypress='return (event.charCode == 8 || event.charCode == 0 || event.charCode == 13 || event.charCode == 46) ? null : event.charCode >= 48 && event.charCode <= 57' onblur='if(innerHTML.length <= 0) { innerHTML = 0 }else{ innerHTML = innerHTML, checkInput(parentNode.id)}'>$pcbp</td>
    <td contenteditable='true' class='editableData' onkeypress='return (event.charCode == 8 || event.charCode == 0 || event.charCode == 13 || event.charCode == 46) ? null : event.charCode >= 48 && event.charCode <= 57' onblur='if(innerHTML.length <= 0) { innerHTML = 0 }else{ innerHTML = innerHTML, checkInput(parentNode.id)}'>$rabat</td>
    <td class='nonEditableData'>$pcsp</td>
    <td class='nonEditableData'>$pvsp</td>
</tr>

As you can see inside 3 td i run javascript function checkInput(parentNode.id)

Function looks like this:

function checkInput(stavkaID)
{
    alert(stavkaID);
}

And it works like charm but now what i want is to somehow get values of each row tr where stavkaID is selected one.

So how it went in my head is to somehow inside function i do something like this

function checkInput(stavkaID)
{
    var naziv = getElementById(stavkaID).nowSomehowIdentifyTDWithValueFor(naziv).innerHTML;
    //And like this for other 5 variables
}

I know i can loop through each element of tr with this but problem is identifying td my loop is currently at.

I cannot set id for td since it will be static and next time i create tr it will have same id which is not possible.

Use this.

onkeypress="...; checkInput(parentNode.id, this)"

and

function checkInput(stavkaId, td) {
   console.log(stavkaId, td);
}
