I'm really tired, I've been working from noon to 9 pm yesterday and from 1 am to 5 am this morning. On May 13, 5:40 am, pantag oh wait, just realized, the script is executing before the div exists so slide is null. - Hide quoted text - ruel <rasmussen.br@gmail.com> wrote: > the browser is firefox > the javascript: > function slideshowchecker(){ > if(document.getElementById){alert('it works');} > slide = document.getElementById("slideX"); > if(slide==null){ > alert('yes2'); > } > } > window.onload=slideshowchecker(); > the document has a div id = slideX. > both alerts keep coming up. > here is the html > <!DOCTYPE HTML PUBLIC > "-//W3C//DTD HTML 4.01 Transitional//EN" > "http://www.w3.org/TR/html4/loose.dtd"> > <html><head><title>slideshow</title><script > src="jscripts/GTA.js" ></head><body><div class="slide" id="slideX"> > grrrrrrrr > </div></body></html> > Why is slideX coming up null? > I'm really tired, I've been working from noon to 9 pm yesterday and > from 1 am to 5 am this morning. - Hide quoted text - pantagruel wrote: > ruel <rasmussen.br@gmail.com> wrote: >> the browser is firefox >> the javascript: >> function slideshowchecker(){ >> if(document.getElementById){alert('it works');} >> slide = document.getElementById("slideX"); >> if(slide==null){ >> alert('yes2'); >> } >> } >> window.onload=slideshowchecker(); window.onload = slideshowchecker; Don't use the call operator, when assigning functions to events.
