Is there a way using javascript (or otherwise) one could have a form such that a different script is called depending on some of the variables used. Just for example, if a person selects 'member' from a dropdown menu,, the form calls perl script 1 and if the person selects 'guest', the form calls php script 2. |

Hello myq-ga
Thank-you for your question.
This can be achieved by using the following code.
First of all you need the form on your page, it should be something like this:
<form name="myform" onSubmit="return submitForm(this.select.value)"
action="" method="post" >
<select name="select">
<option value="member" selected="selected">Member</option>
<option value="guest">Guest</option>
</select>
<input name="Submit" type="submit" />
</form>
Notice, the name of the form and the onSubmit parameter. This calls
the submitForm javascript function when the form is submitted. One
parameter, the value of the dropdown box, is submitted to the
javascript function when the form is submitted.
The javascript to redirect you to another script would be done like
this and should be placed in the <head> section of your page:
<script>
function submitForm (choice) {
if ( choice == "member" ) { document.myform.action = "member.html" }
else { document.myform.action = "guest.html" };
document.myform.submit();
};
</script>
Basically, this says if the value submitted (choice - which comes from
the dropdown box on the form) is equal to 1 then submit it to
"member.html" otherwise it goes to "guest.html". Hopefully you should
be able to edit this easily for your own use.
If you have any questions on this subject please ask for clarification
and I will do my best to respond swiftly. | |

I have worked with a similar function before, and there IS a browser
specific bug with it, under certain circumstances. In Internet
Explorer (IE) for Windows (at least version 6+), if you have an html
form tag with the name of 'action', this function tries to set that
tag to whatever value the function states, instead of setting the
action property of the form object. Obviously, this does not work, and
results in weird failure. Here's an example:
<form name="myform" onSubmit="return submitForm(this.select.value)"
action="" method="post" >
<!--This is the offending code for IE-->
<input type="hidden" name="action" value="process">
<!--End offending code-->
<select name="select">
<option value="member" selected="selected">Member</option>
<option value="guest">Guest</option>
</select>
<input name="Submit" type="submit" />
</form>
The function is identical to the one palitoy wrote.
As far as I can tell, there is no easy workaround for this. It sounds
like you probably won't be dealing with something this specific, but I
though you should know, since you asked the question. |
