链接js文件在php
PHP is completely irrelevant for what you are doing. The generated HTML is what counts.
In your case, you are missing the src attribute. Use
<script type="text/javascript" src="file.js"></script>
如何加javascript php文件
//this is my code
you can add javascript to your code by using the echo statement and rap all
your javascript between "" and if there is "" in the javascript code
then add \ before any "", and for the php inside rap it with ''
<?php
echo "<script>document.write(\"hello world\")</script>"
?>
//other example
<?php
$a = 5;
echo "<script>document.write('$a')</script>"
?>
//other example
<?php
$TokenData = Auth::user();
echo "<script type=\"text/javascript\">
localStorage.setItem(\"id\", '$TokenData->id');
localStorage.setItem(\"name\", '$TokenData->name');
localStorage.setItem(\"email\", '$TokenData->email');
</script> ";
