  • 0

I have an image in HTML/PHP with different areas. When I click on one of the areas I want my input field above to change. How do I do that? Trying to use a normal $variable but I dont get that to work either.

I am very new to HTML.

Thanks in advance! 

<input type="text" name="position" size="10" value="">

<img style="margin: 50px 500px" src="pic.jpg" width="500" height="200" alt=":("
usemap="#cabmap" />

<map name="cabmap">
<area shape="rect" coords="20,0,82,126" alt="Sun" *something here mby?* />



<html>
<head>
<title>Pos</title>
</head>

<body>

<form method="post" action="process.php">
<fieldset>
<legend><strong>ChosePos</strong></Legend>

<td style="padding-left: 40px"><b>Position</b></td>
<input id="position" type="text" name="position" size="10" value="Hellope"</input>
<br />
<img src="pic.jpg" width="500" height="200" alt="Position map" usemap="#map" />
<map name="map">

  </script>

    UPDATE – if this is still marked as the “correct” answer…

    I have tried explaining to the OP that my answer was based on the errors they had introduced when implementing the changes suggested by user1474090. And as a result, they should mark the answer from user1474090 as the “correct” one… and not this one.

    Original Answer

    In response to your updated question, you have a couple of syntax errors.

    Firstly, your <input id="position" is badly formatted, so change…

    <input id="position" type="text" name="position" size="10" value="Hellope"</input>

    Into one of the following two lines…

    <input id="position" type="text" name="position" size="10" value="Hellope"></input>
<input id="position" type="text" name="position" size="10" value="Hellope"/>

    Secondly, your JavaScript function doesn’t have a close brace }, so change…

    <script type="text/javascript">
  function simply(){
  var box = document.getElementById("position");
  box.value="Hello";
</script>

    To…

    <script type="text/javascript">
  function simply(){
    var box = document.getElementById("position");
    box.value="Hello";
  }
</script>

    I would also suggest that you move the <script> block into the <head> section of your page, rather than being part of the <body>. This is not vital for it to work, but it is the preferred way of having scripts in your page.

    And I can thoroughly recommend FireBug for Firefox or use the developer components in Chrome and IE8/9 (F12 for both). These would very quickly allow you find issues like this.
