Q:

Object doesn't support property or method 'attachEvent' InternetExplorer 11

If I press the form send button "Saada" in IE11, I will get an error:
Object doesn't support property or method 'attachEvent'

I have found that this is an IE11 problem, but the only solution I have found is to use my developer tools and set the browser to run in IE9 mode for example.
But I want everyone to use my website without using their developer tools.
Do you know some other solution I could try. Or maybe I have to import some other Jquery libraries?
Other browsers work fine, but this only happens in IE11

A:

The javascript method attachEvent was replaced with the method addEventListener in IE11.
JQuery 1.10.1 still uses this method in case of IE > 8. This will cause javascript compilation errors.
JQuery 1.10.2 seems to have solved this problem.
Hope this will help

A:

attachEvent is a deprecated function used in older versions of Internet Explorer.
For modern browsers use this instead.
el.addEventListener(evt,func,false);

See documentation here
You could also create a function which checks which function to use
function addListener(el, event, func){
    if (el.addEventListener) {
       el.addEventListener(event, func, false);
    }
    else {
       el.attachEvent("on"+event, func);
    }
}

Then you can attach your event by doing this:
var element = document.getElementById('myElement');
addListener(element, 'click', function(){
    alert('You have clicked!');
});

If you are unable to to this then perhaps a polyfill will work instead. Try to insert this somewhere:
if(!document.attachEvent){
  Object.prototype.attachEvent=function(event,func){
    this.addEventListener(event.split('on')[1], func);
  }
}

Hope this helps
