    Confused on how to merge javascript with php

    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:

    Code:
    <?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

          Code:
          <?php

echo("<html><body>");
echo("<TITLE>COMBO2.PHP</TITLE>");
echo("<BR><B><U>THIS Is the test to combine php javascript and html<br></U>");
echo("<BR><BR>");


echo("<script type="text/javascript"><!--\n");
echo("function editLink() { ");
echo("var myLink = document.getElementById('my_link'); ");
echo("var myInput = document.getElementById('my_input'); ");

echo("myInput.value = myLink.innerHTML; ");
echo("myLink.style.display= 'none'; ");
echo("myInput.style.display = 'inline'; ");
echo("} ");

echo("function doneEdit() { ");
echo("var myLink = document.getElementById('my_link'); ");
echo("var myInput = document.getElementById('my_input'); ");

echo("myLink.innerHTML = myInput.value; ");
echo("myLink.style.display = 'inline'; ");
echo("myInput.style.display = 'none'; ");
echo("} ");

echo("//--></script>");

echo( "<a id="my_link" href="javascript:editLink()">Click Me</a> ");
echo( " <input type="text"  style="display: none;" ");
echo( "id="my_input" ");
echo( "onblur="doneEdit()"/> ");
echo("<br>");
echo(" </body></html>");
?>

              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.
