I have included a javascript in the module "myid" I've been developing in drupal by using this code:

function myid_init() {
    drupal_add_js(drupal_get_path("module", "myid") . "js/myid.js");   
}

This is my Javascript file "myid.js":

function myid_js_start(){
    alert("hello world");
}

Below is the code that creates a button that invokes an alert function:

$form['add_button'] = array(
    '#type' => 'button',
    '#value' => 'Take a picture',
    '#attributes' => array('onclick' => 'myid_js_start()'),    
);

I dont know where did I go wrong. The button shows up but doesn't fire any alert function. Can anyone help me with this?

Standard question: have you cleared your cache? Have you tried specifying that the function is javascript as per stackoverflow.com/questions/21032365/… –  Darvanen Jan 12 at 4:05
    
I always clear the cache, everytime I make changes. –  XXX.xxx Jan 12 at 5:10

Sadly there are too many who post here that do not know to do that, therefore it is helpful to include that fact in your question =) –  Darvanen Jan 12 at 5:21

Try to write JS in drupal way like this:

(function($) {

    Drupal.behaviors.xyzModule = {
        attach: function(context, settings) {


//            $('.test', context).click(function() {
//                $(this).next('ul').toggle('show');
//            });

//myid_js_start();
            function myid_js_start() {
                alert("hello world");
                //console.log(' Hello');
            }

        }
    };

})(jQuery);

This:

drupal_add_js(drupal_get_path("module", "myid") . "js/myid.js");

Needs to be:

drupal_add_js(drupal_get_path("module", "myid") . "/js/myid.js");

Note the forward slash before the path to the js file
