execute function after complete page load

Question

I am using following code to execute some statements after page load     lt script type  text javascript  gt      window onload   function                newInvite            document ag src  b jpg          lt  script gt    But this code does not work properly  The function is called even if some images or elements  are loading  What I want is to call the function the the page is loaded completely

I can tell you that the best answer I found is to put a "driver" script just after the </body> command. It is the easiest and, probably, more universal than some of the solutions, above.

The plan: On my page is a table. I write the page with the table out to the browser, then sort it with JS. The user can resort it by clicking column headers.

After the table is ended a </tbody> command, and the body is ended, I use the following line to invoke the sorting JS to sort the table by column 3. I got the sorting script off of the web so it is not reproduced here. For at least the next year, you can see this in operation, including the JS, at static29.ILikeTheInternet.com. Click "here" at the bottom of the page. That will bring up another page with the table and scripts. You can see it put up the data then quickly sort it. I need to speed it up a little but the basics are there now.

</tbody></body><script type='text/javascript'>sortNum(3);</script></html>

I m little bit confuse that what you means by page load completed   DOM Load  or  Content Load  as well  In a html page load can fire event after two type event    DOM load  Which ensure the entire DOM tree loaded start to end  But not ensure load the reference content  Suppose you added images by the img tags  so this event ensure that all the img loaded but no the images properly loaded or not  To get this event you should write following way   document addEventListener  DOMContentLoaded   function           your code here    false     Or using jQuery         document  ready function       your code      After DOM and Content Load  Which indicate the the DOM and Content load as well  It will ensure not only img tag it will ensure also all images or other relative content loaded  To get this event you should write following way   window addEventListener  load   function            Or using jQuery     window  on  load   function      console log  All assets are loaded

This way you can handle the both cases - if the page is already loaded or not   document onreadystatechange   function        if  document readyState      complete            myFunction              else          window onload   function                myFunction

I tend to use the following pattern to check for the document to complete loading  The function returns a Promise  if you need to support IE  include the polyfill  that resolves once the document completes loading  It uses setInterval underneath because a similar implementation with setTimeout could result in a very deep stack   function getDocReadyPromise       function promiseDocReady resolve          function checkDocReady               if  document readyState      complete                   clearInterval intervalDocReady           resolve                      var intervalDocReady   setInterval checkDocReady  10         return new Promise promiseDocReady       Of course  if you don t have to support IE   const getDocReadyPromise        gt      const promiseDocReady    resolve    gt          const checkDocReady        gt          document readyState      complete    amp  amp   clearInterval intervalDocReady     resolve          let intervalDocReady   setInterval checkDocReady  10         return new Promise promiseDocReady       With that function  you can do the following   getDocReadyPromise   then whatIveBeenWaitingToDo

Put your script after the completion of body tag   it works

You re best bet as far as I know is to use window addEventListener  load   function         console log  All assets loaded        The  1 answer of using the DOMContentLoaded event is a step backwards since the DOM will load before all assets load  Other answers recommend setTimeout which I would strongly oppose since it is completely subjective to the client s device performance and network connection speed   If someone is on a slow network and or has a slow cpu  a page could take several to dozens of seconds to load  thus you could not predict how much time setTimeout will need  As for readystatechange  it fires whenever readyState changes which according to MDN will still be before the load event   Complete The state indicates that the load event is about to fire

Alternatively you can try below     window  bind  load   function         code here       This works in all the case  This will trigger only when the entire page is loaded

this may work for you    document addEventListener  DOMContentLoaded   function           your code here    false     or if your comfort with jquery     document  ready function       your code         document  ready   fires on DOMContentLoaded  but this event is not being fired consistently among browsers  This is why jQuery will most probably implement some heavy workarounds to support all the browsers  And this will make it very difficult to  exactly  simulate the behavior using plain Javascript  but not impossible of course    as Jeffrey Sweeney and J Torres suggested  i think its better to have a setTimeout function  before firing the function like below    setTimeout function       your code here    3000

Try this jQuery     function         Handler for  ready   called

User · Answer

If you can use jQuery  look at load   You could then set your function to run after your element finishes loading  For example  consider a page with a simple image   lt img src  quot book png quot  alt  quot Book quot  id  quot book quot    gt   The event handler can be bound to the image      book   load function          Handler for  load   called       If you need all elements on the current window to load  you can use   window  load function           run code      If you cannot use jQuery  the plain Javascript code is essentially the same amount of  if not less  code  window onload   function          run code
