javascript execution

You need to click Yes to start debugging

i did debugging but there is nothing wrong i felt or got in script just that the button event doesnot get fired

if i add alert

after the button click event line  debugged  in script it goes to button click event in the code behind page

but without alert the code behind page doesnot get executed

Well then check whether you have done it properly using onclick event. there's soemthing you have done wrongly just it is somehow working in FireFox does not mean it is correct hence check properly.

 document.getElementById('<%=posyback.ClientID %>').click();

posyback is a button

and in code behind

 protected void posyback_Click(object sender, EventArgs e)         {

queries

1)if anything wrong then atleast FF shld generate error

2) in FF it works even without alert

3) in IE it works only with alert

i mean when IE has alert in teh script the

protected void posyback_Click(object sender, EventArgs e)         {

event gets fired

4) if the event shld not get fired than it shld not in IE insppite of having alert or not

just this r the lines of code

so whts excatly hampering the button click event when no alert in script is

Did you add breakpoint server side? Is the breakpoint hit?
