javascript function not working

hi ,


function markpayment(orderNumber)
{

alert();


}


this is not working

onclick='javascript:markpayment('".$ordernum."_tick');'

but this is working


onclick='javascript:markpayment(".$ordernum.");'

it does not matter what it looks like in php...as long as some valid html is generated it will work...you have to show us the generated the html or the complete echo statement from php

I saw the html it was

markpayment('23434_tick') it was not working

but

markpayment(23434)

was working

I think problem was when i added tick with it . I later on concatenated tick in the function and then it worked but not when i joined it with in function arguments

markpayment('23434_tick') it was not working
but
markpayment(23434)
was working


they're both no different and should work...maybe you are looking in the wrong place...are you sure there isn't some validation that checks if the incoming argument is an integer or something?

Change:
function markpayment(orderNumber) {
alert(orderNumber);
}

The problem is that the browser sees the onclick event as markpayment( not onclick='markpayment('23434_tick')' because of how many quotes you have.

Change the output so that it looks like:

onclick="markpayment('23434_tick')"
