How can I tell if an element has not been loaded yet?

I have a piece of code that needs an element. The element is dynamicly loaded so I need to check if it has been loaded so I can execute my script. How could I do this?

This has not been giving me errors before, but now it is... strange

Javascript Code:

echeck = document.getElementById('etobechecked');
if(echeck != null)
{
  //code here
}

Hi,

I have also used a similar method, it works fine for me.. Here is the code, you may give it a try,

function loadelement() //to append an element to a form tag with id="F1"
    {
        var el = document.createElement("input");
        el.setAttribute("id","dynelement");
        el.setAttribute("type","button");
        el.setAttribute("value", "hi");
        el.setAttribute("onclick","test()");
        f1.appendChild(el);
    }
    
    function checkelement() //to check for the presence of this element.
    {
        if(document.getElementById("dynelement")!=null){
        alert("loaded");}
        else{
        alert("not yet loaded");}
    }

------------ the following is the html part for this -------
<input type="button" id="b1" onclick="loadelement()" value="addelement" />
    <input type="button" id="check" onclick="checkelement()" value="Check for Element" />

Code (markup):

I am dubious that you may have invoked the checking script prior to appeding script.

you can try:
if(document.getElementById("ElementID")){
// your code
}

 

Thanks, it worked!
