eval(funcname) works; call() and apply() don't. &nbsp;Many thanks!

eval(funcname) works; call() and apply() don't.  Many thanks!

<div>
That goes like this:<br />
<br />
function onTaskSelect(e){<br />
&nbsp; var funcname = 'ol' + e.id;<br />
&nbsp; window[funcname]();<br />
}<br />
<br />
Attached the full tested code:<br />

<pre><code id="code-997583">&lt;script&gt;

var myObj = {id:1};

onTaskSelect(myObj)


function onTaskSelect(e){
  var funcname = 'ol' + e.id;
  window[funcname](42);
}


function ol1(myParam){
  alert(myParam);
}

&lt;/script&gt;
</code></pre>

<div class="content wysiwyg-content">
I'm sure this is trivially easy, but Javascript is not my strong suit.<br />
<br />
I have a js file with numerous functions named ol1(), ol2(), ..., ol<i>n</i>().<br />
<br />
In this function on my page:<br />
<br />
<i>function onTaskSelect(e)<br />
{<br />
var funcname = 'ol' + e.id + '()'<br />
?.......?<br />
}</i><br />
<br />
how do I call the function &nbsp;in the js file named <i>funcname</i>?

I'm sure this is trivially easy, but Javascript is not my strong suit.

I have a js file with numerous functions named ol1(), ol2(), ..., oln().

In this function on my page:

function onTaskSelect(e)
{
var funcname = 'ol' + e.id + '()'
?.......?
}

how do I call the function  in the js file named funcname?

Call Javascript function from another js function using variable name

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
