Array Jquery in function

Question

How to make array in function with options to run. This is declaration:

$(".object").myfunction({
    run1: 'spell',
    run2: true
});

Here is function:

$.fn.myfunction= function() {
    alert(run1);
};

How to alert the run1 or run2 from declaration ?

Why would you want to do that? why are you adding functionality to the base jQuery object if the functionality doesn't use the object? — Amit

Add an object for the function to receive

$.fn.myfunction= function(params) {
    alert(params.run1);
};

@Mergars, is the function declaration before or after the invocation?

Can you tell me, how spell function without params or with params (2 functions on 1 page) It's desn't works with your result.

javascript cannot overload functions in the way you are suggesting. If you try - only the last will work. What you can do - is check what you have received, i.e. if (params === undefined){/*code for no params*/}else{/*code with params*/}

My proposal is:

$.fn.myfunction= function(obj, key) {
  alert(obj[key]);
  /*****
            $.each(obj, function(index, element) {
               alert("Key: " + index + " Value: " + element);
            });
             *****/
};
$(function () {
  $(".object").myfunction({
    run1: 'spell',
    run2: true
  }, 'run1');
});

<script src="http://code.jquery.com/jquery-1.11.3.js"></script>


<button class="object" style="visibility:hidden">Click Me</button>

@Mergars Thanks so much in any case. I updated my snippet.

No problem, but you created function with only 2 params. Thanks again :)
