Simple javascript that loads a URL variable into a form input tag

Try this
http://stackoverflow.com/questions/4877966/pass-a-simple-url-variable-into-and-input-field-via-javascript

document.getElementById("input_id").value = location.search.replace('?','');

Select all Open in new window

@leakim971 that worked except I'm getting too much information passed through. This was in the input field:

myemail@address.com%3fEMAIL%3d%40EMAIL%40

How can I strip the rest of the information out? Sample of the code I used is attached.

<script language="javascript">
var gup = function( name ) {
    var results = (new RegExp("[\\?&]"+name+"=([^&#]*)")).exec(window.location.href);
    if ( results == null ) {return ""}
    else {return results[1]}
};

window.onload = function() {
    document.getElementById("emailaddie").value = gup("EMAIL");
}
</script>

Select all Open in new window

Thank you!

Why do you put all this information?
Parameter in a URL must be separate by the << & >>

It looks like the script is not parsing the data that includes and follows the << ? >>.


So, in this URL...
http://www.URL.com/?EMAIL=@EMAIL@

The script is capturing:
myemail@address.com%3fEMAIL%3d%40EMAIL%40

%3fEMAIL%3d%40EMAIL%40 is equal to ?EMAIL=@EMAIL@

Have I made myself clear?

Hold on! I've found the error. You were correct in asking me why so much info. There was a typo. The solution is fine! Thank you!!
