如何用php触发JavaScript函数[关闭]

Question

Ok so I have a PHP document wich saves the contents of a text input how do I trigger a function in a .js file when it's done . I've done the part with the uploading I just can't figure out how to trigger the js function

Answer 1

You can simply do this:

echo "<script src='myScript.js' type ='text/javascript'> myFunction(); </script>";

Im not exactly sure what functionality you're trying to get working but if this is supposed to be some kind of data controller where you simply process data, calling echo may give the user a blank screen, so you will want to redirect the user like so

header('Location: redirectLocation');

Do try to provide more details in future questions, but i hope this answered your question.
