Confused on how to merge javascript with php

36 New Member

Wutup

Im trying to write a php script that has a link. When the user clicks the link the link turns into a text field which the user can modify. When the user clicks elsewhere the text that the user typed is turned back into a link. Ive got the php script which Im supposed to change and I got a piece of javascript code that does the whole link changing of link to textfield and back again thing.

Problem Im having is I dont understand how to combine the two together. I tried to echo the javascript tags similar to how html tags can be echoed but that didnt work. I googled and found examples similar to this:

Expand|Select|Wrap|Line Numbers

 
<?php
 
echo("This is php");

?>
 
<script....

//javascript stuff goes here

</script>

Is there any way I can put the javascript within the php part of the code?

Thanks

Javascript calls belongs within the HTML.
Ideally close the php tags then write the HTML.
[PHP]<?php
echo("This is php");
?>
<script...etc >
//javascript stuff goes here
</script>[/PHP]
If you must place within php then echo out the HTML
[PHP]<?php
echo("This is php");
echo '<script>
//javascript stuff goes here
</script...etc>';
?>[/PHP] But I suspect this is not what you are asking

Actually I tried just echoing out the javascript. I have a bunch of javascript functions and html lines that call these functions. When I try just echoing it out I get a blank page.

I shouldve just posted the code Im working with right off the bat here it is its pretty short. Can you take a look maybe theres an error I dont see ?

Thanks

echo("<script type="text/javascript"><!--\n");

echo("function editLink() { ");

echo("var myLink = document.getElementById('my_link'); ");

echo("var myInput = document.getElementById('my_input'); ");

Well for a start echo is not a function so you don't need brackets.
Nor in this situation do I see a need for echo, just place the code ouside the php tags.
i am a little confused with why you are using php.
Anyway, I don't see a <head> tag even though you are using <title>.
Javascript is touchy about things like that

Im trying to do it this way because Ive got a huge php script to modify in the same way and I dont know if I ll be able to seperate the it into 2 php blocks. and the <head> tag didnt do anything when I added it in.

I guess I ll try it on the huge one and see wut happens cant hurt now that I think of it.

Worst case scenario I ll have to convert these javascript functions to php functions (hopefully it ll be possible).

I take it you are aware of Javascript being client-side and php being server-side and the implications of mixing the two?

yea I guess thats gonna be a problem. Wutever I ll just seperate the huge script and see if that works. If not I ll just rewrite the javascript into php.
