I'm using magento 1.9 version.

I am creating custom module, which contains some javascript functions to be included.

I defined all javascript functions in seperate js file and included that js in my xml file under app\design\mytheme\default.

Called the js function in my phtml file. It shows the error : (index):403 Uncaught ReferenceError: myFunction is not defined. How to solve this.

  • can you attach XML and JS files here?

  • Sorry i cannot attch my whole XML and JS files due to my company principles. Jul 6 '16 at 9:26

there can be several reasons of this issue:

1) Js file is not added to page (if something wrong in your XML)

2) Js file not added in Merged js file (so you can clean JS/Css cache at the bottom of Admin - System - Cache Management page)

3) Js file added, but it's code structure broken.

4) Js file added at the bottom of page, but function called before file insertion

  • Thanks for your reply @Neklo. The step 4 is caused my case. Because i called the function On document ready function. But i included the js as normal like <action method="addJs"><script>mymodule/mymodule.js</script></action>. Jul 6 '16 at 9:23

  • if <action method="addJs"> code added to <reference name="head"> section - you need to clean JS/Css cache at the bottom of Admin - System - Cache Management page
