Re: passing variables from php to javascript

I use the attached javascript function to get the values of a form, and then open a new window that is about the size of an alert box. It takes the form inputs and build an http get request that php can use in the new windows. A sort of pseudo alert box. Hope this helps. Robert Zwink ----- Original Message ----- From: "B.

I am including the code. Everything works as is, but I also need to pass a variable from the html/php into the javascript function to print out the string length of the text post. Please let me know how this can be done. I have included the code below for suggestions. thanks Keith <? ?> <DEFANGED_script language="javascript"> function string_length() { string_count = "4"; alert ("The sequence is " +string_count+ " long"); return; } </script> <form action="mailto.php3" method="post"> <table border="0"> <? for ($i = 1; $i <= $number_of_oligos; $i++): ?> <tr> <td> <? echo ("sequence $i") ?> </td> <td> <input type="text" name="sequence[]"><br><br> </td> <td> <input type="button" name="length" value="How long is my sequence?" DEFANGED_OnClick="string_length()" <br><br></td> </tr> <? endfor ?> <tr> <td><input type=submit> </tr> </table> </form>
