Function Expected Error in javascript

Question

for dynamically created check box when it is clicked i want to grab the attribute value.It is working in IE 8,9,10 but not working in IE 11,chrome shows function expected error

<input type=checkbox checked='checked' id='SymptomFailureCodeId' TabIndex='54' style='cursor:pointer;' onclick=ChkClickEvt(this);  FailureCodeId="1" >


function ChkClickEvt(Obj) { 
    alert(Obj.attributes("FailureCodeId"));
}

Is this a typo, or do you literally have this onclick=ChkClickEvt(this); where the command is not wrapped in "? — Mike Perrenoud

Try using getAttribute instead:

Obj.getAttribute("FailureCodeId")

Or if you want to use attributes property don't use it as a method. It's a NamedNodeMap.

For example:

Obj.attributes["FailureCodeId"]

But be aware that this no longer supported on Firefox > 22 and many modern browsers. Read more about this at MDN

Why do you need this check? Use always getAttribute. It's cross browser and have better support.

A better method would be using HTML5 data-* attributes.

Markup

<input type='checkbox' id='SymptomFailureCodeId' data-FailureCodeId="1" />

JavaScript

var article = document.querySelector('#SymptomFailureCodeId'),
          data = article.dataset;
console.log( data.FailureCodeId );

P.S: You would be golden with this and this

P.P.S: I am fairly sure that making up custom attributes like that is not the best practice. I am searching for further evidence to back my argument. ;)
