check if object created?

[vurentjie]

hi,

i am having a bit of a problem with a call to setInterval on a page,

it seems to be because of the mysql queries run,

if i just run a regular query that calls the data from tables, the script works fine,
but if i first save data then request it after it has been saved, it seems like the objects don't get created before the setInterval is called, at least this is what i am guessing at,

i have thought of moving some of my mysql updates to another page and then redirecting, but this is not the ideal solution, so i was wondering

if i have say a <input type='hidden' value='dfdf' id='mmm'/>

is there any way i could check if this object exists before declaring

var soso = document.getElementById('mmm').value;

something like
if(!document.getElementById('mmm')){}

Code: Select all

if(document.getElementById('mmm'))
alert('Element mmm already loaded')
