why settimeout not delay the function execution?

Question

function tryToDownload(url)
{

       oIFrm = document.getElementById(\'myIFrm\');
       oIFrm.src = url;
      // alert(url);
      // url=escape(url);

      setT         


        

Answer 1

That's because you are calling the function, and using the return value in the setTimeout call. Wrap it in an anonymous function so that it's called by setTimeout:

function tryToDownload(url) {

    oIFrm = document.getElementById('myIFrm');
    oIFrm.src = url;
   // alert(url);
   // url=escape(url);

   setTimeout(function() { deletefile(url); }, 25000);

}
