Thanks Nushi - that isn't the problem. (BTW lowercase tr works fine too). The tr element is being created correctly.
What I need is to add an event to this element.

Question
Add events at run time
In my code, I have a
trow = document.createElement ("tr");
trow = orderdetails.insertRow();
Is there a way I could create an event (say Click) to this element? Something like
onclick = "alert('row clicked');" ??
Thanks!

Nushi - Another question. When are the parameters resolved? For example in the code below:
for(i = 1; i <= objLst.length -1; i++)
{
if (j == 1)
{
trow = document.createElement ("tr");
trow = orderdetails.insertRow();
curroid = objLst.item(i).text;
alert(curroid) ; //-----> this shows the correct id
trow.onclick= function(){ showProducts(curroid); };
}
.....
.....
But when I have an alert within showProducts, the input argument is always the last of curroids.
For example if I have three rows with ids 1, 2, 3 - no matter from where I call showProducts, the input is always 3.
Thanks!
Hello svid,
put the var declaration for curroid Outside of the function definition and assign the latest value in the function.
The onclick event is outside of the scope where the curroid is defined if curroid is not global.
Like this:
var curroid;
function xyz(){
//...
for(i = 1; i <= objLst.length -1; i++){
if (j == 1){
trow = document.createElement ("tr");
trow = orderdetails.insertRow();
curroid = objLst.item(i).text;
alert(curroid) ; //-----> this shows the correct id
trow.onclick= function(){ showProducts(curroid); };
}
}
Good luck,
ZeroPage
Sorry, wrong.
var curroid;
function xyz(){
//...
for(i = 1; i <= objLst.length -1; i++){
if (j == 1){
trow = document.createElement ("tr");
trow = orderdetails.insertRow();
curroid = objLst.item(i).text;
alert(curroid) ; //-----> this shows the correct id
trow.onclick= function(){ showProducts(); };
}
}
function showProducts(){
alert(curroid);
}
By making it global, wont it always be the latest value?
for example, I have 3 rows
1 - on click of this row I want showProducts(1)
2 - on click of this row I want showProducts(2)
3 - on click of this row I want showProducts(3)
By making it global, after row 3 is created, curroid would be 3
so ShowProducts will always execute with 3, no matter which row is selected.
What I would like is the foll, but with everything created at runtime
<table>
<tr onclick= "showProducts(1)">....</tr
<tr onclick= "showProducts(2)">....</tr
<tr onclick= "showProducts(3)">....</tr
</table>
Thanks for your help.
Ok, then change it to this:
function xyz(){
//...
for(i = 1; i <= objLst.length -1; i++){
if (j == 1){
trow = document.createElement ("tr");
trow = orderdetails.insertRow();
curroid = objLst.item(i).text;
alert(curroid) ; //-----> this shows the correct id
trow.onclick= new Function("showProducts("+c
}
}
