Can somebody help me with this problem. In the body of a Basic page:
drupal_add_js(array('my_var' => array('orderid' => '123')), 'setting');
drupal_add_js('sites/all/scripts/printout.js');
In printout.js:
alert("Before");
alert(Drupal.settings.my_var.orderid);
Result: "Before" was alerted then returned to Basic page, no orderid. What have I done wrong?
Make sure you call for jquery setting inside Drupal behaviour, you can do like this:
(function ($) {
Drupal.behaviors.example_name = {
attach: function(context) {
alert(Drupal.settings.my_var.orderid);
}
}
})(jQuery);
or you can call inside jQuery's .ready() event (less preferable than behaviours approach in Drupal world):
jQuery(document).ready(function($) {
alert(Drupal.settings.my_var.orderid);
});
These both approaches ensure that jQuery is loaded before calling a variable.
P.S. I recommend using console.log instead of alert for quick debugging, like this:
console.log(Drupal.settings.my_var.orderid);
Then go to your developer console / firebug (depending on browser you use) and you'll see an output in console.
You have to say drupal where to put the javascript like this:
$options = array(
'weight' => 1000, // High number to push this file to the bottom of the list
'scope' => 'footer' // This will output the JS file in the footer scope, so at the end of the document
);
drupal_add_js(drupal_get_path('module', 'modulename') .'/script.js', $options);
But like i learned a more sophisticated way would be to use Drupal.behaviors.
Look at my question: How to pass values from php to javascript properly?
