Javascript wont run when include tags are echoed to <head> - PHP, JS, HTML
Hey, I just made a simple function to load JavaScript files from a template view, like this:
public function includeJavascript($file){
if(file_exists('path/to/js/' . $file)){
$this->set('script', '<script type="text/javascript" src="/path/to/js/' . $file . '"></script>');
}
}
The string is passed via $script and gets printed in the main layout. This means that when I render the page I actually get: <script type="text/javascript" src="/path/to/js/myjavascript.js'"></script> in the HTML, but the JavaScript code wont run. Why 开发者_运维问答is this?
Sincerely, Why
Temporarily add this line to the top of myjavascript.js as a sanity check..
alert('found myjavascript.js OK!');
Try this:
public function includeJavascript($file){
if(file_exists('path/to/js/' . $file)){
$this->set('script', '<script type="text/javascript" src="/path/to/js/' . $file . '"></script>');
}
}
Addded an apostrophe prior to path/to/js/ in the file_exists function.
If you look at the code you posted in the HTML:
<script type="text/javascript" src="/path/to/js/myjavascript.js'"></script>
Note the extra apostrophe after myjavascript.js? That's why it won't work.
