Question

I have ajax domain lookup script.

Look here for DEMO:

Here is JS code for Ajax form Textarea1

Here is HTML code for Ajax textarea1

<form onSubmit="checkDomain();return false;" id="ajaxDomainForm" action="">
<input name="domain" type="text" id="domain" style="font-size:2em; width:60%;" onKeyUp="checkForChange();" maxlength="255">
<div id='statusDiv' style="font-weight:bold">Type a domain name!</div><br>
<textarea name="domainsAvailableInput" cols="40" rows="7" id="domainsAvailable" readonly="readonly"></textarea>
<div id='whatDomainDiv' style="font-weight:bold">Domain</div>
<div id='isAvailableDiv' style="font-size:5em">?</div>
</form>

Here is HTML code for NON-Ajax Form textarea2

<form id="" method="post" action="/domainchecker.php?search=bulk">
<textarea name="bulkdomains" cols="60" rows="8"></textarea>
<input type="submit" id="Submit" value="Lookup">
</form>

What I want is, Once I get ajax response from server in textarea1, Copy / append it to textarea2.

The reason for this is I am unable to perform action within textarea1 due to limitations of domainchecker.php of form2

How Can I achieve this ?

Thanks.

He…he.. This Worked.

See Working DEMO

    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>

//These are my two textboxes as I mentioned in my Question.//

    <textarea name="domainsAvailableInput" id="domainsAvailable" cols="60" rows="8"></textarea>

    <textarea name="bulkdomains" id="client" cols="60" rows="8"></textarea>

// On clicking this checkbox textarea1 value is copied to textarea2.//

    <input type="checkbox" id="Get">

    <script type="text/javascript">
        $("input:checkbox").click(function () {
     if (this.checked) {
       $('#client').val($('#domainsAvailable').val());
     } else {
       $('#client').val($('').val());
        }
        });    
    </script>
