Question

i have made an tag trigger function inside an anonymous function , here it is :

(function(){
  var getElement = {
    getElem: function(element , elemInterval){
      if(document.getElementsByTagName('div')[0].onload){
        element = document.getElementsByTagName('div')[0];
        clearInterval(elemInterval);
        element.innerHTML = ' content changed. ';
      }
    }
  }
  var element , elemInterval;
  elemInterval = setInterval(getElement.getElem(element , elemInterval) , 1000);
})();

what it got to do is to call a function as many time as it needs every one second and check if the first div as been loaded , than it save the element port to the “element” var and change the content of the div.

this seems to not work , what’s the problem here?

Answer 1

You’re calling it directly and passing the result value to setInterval, which is undefined.

What you probably want is passing a function to setInterval, which in turn will call getElem:

elemInterval = setInterval(function() {
                               getElement.getElem(element , elemInterval);
                           }, 1000);
