我有ajax域查找腳本。將ajax textarea響應複製/附加到另一個非ajax文本區
看看這裏的DEMO:
這裏是Ajax表單JS代碼Textarea1

</script>
這裏是阿賈克斯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>
這裏的HTML代碼是針對非Ajax表單HTML代碼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>
我想要的是，一旦我從textarea1中的服務器獲得ajax響應，將其複製/追加到textarea2。
這樣做的原因是，我無法執行textarea1內採取行動，由於窗口2
的domainchecker.php的侷限性我怎樣才能做到這一點？
謝謝。

我知道你的建議是善意的，我同意這一點事實，但我在這裏提供溫和的警告上，因此「只是嘗試jQuery的」建議趨於提高梳理。 – Pointy 2010-07-05 14:54:22
感謝您的回覆，但我是新手。對jquery有太多想法。 – MANnDAaR 2010-07-05 14:55:31
