  • 0

I’m completly new to wordpress. I just want to use single javascript snippet on a page. For example:

<script>
function myFunction(){
//do something
}
</script>
// a bit later
<input type="button" name="testButton" onclick="myFunction()">

And in developers console in Chrome I get an error: "Refused to execute a JavaScript script. Source code of script found within request."

I’ve done some research and I think that I know it’s origin – it seems that I have to add an external file with my javascript code. The bad thing is, that I have literally no idea how to do it, in spite of researching for the past few hours. Maybe it’s very easy and I’m missing the simple solution, but I just don’t know how to upload .js file. I’ve bumped into some topics saying that I have to use a php function, wp_enqueue_script(), but it still needs the .js file to be uploaded to wordpress server. Do I have to upload it as Media, a page, or what? And still, if I have to upload a javascript file each single time when I want to change something, application development will be a pain in the butt…

So is there maybe an easy way to put my javascript function definition in the same file where the function is used? That would be possibly the easiest solution.

    Adding external Javascript files is probably the way to go. You upload them in the same way you would do if this was a regular HTML site, (ie using FTP or something similar).

    Then you can reference it in the header.php file (accesible under the Appearance -> Editor in WordPress).

    Some themes allow you to add Javascript to the top/bottom of each page, you may want to check if your theme allows that. (check the manual with the theme or their support).
