How to set onSuccess event listener for Grails
Grails inherently supports ajax function, such as remoteFunction, remoteLink, etc.
But do you know how to set onSuccess event listener appropriately?
Let me tell you
<input type=”text” id=”name” name=”name” value=””/>
<input type=”button” name=”checkbizname” value=”Chek whether this name already exists” onclick=”${remoteFunction(controller:’mycontroller’,action:’isNameExists’,onSuccess:’popwin(o)’, params:’\’name=\’ + document.getElementById(\’name\’).value’)}”/>

暴汗，关于javascript的parseInt()的一个问题
这几天在做系统的时候，突然发现时间选择框选择出来的时间总是报告格式不对，通过debug发现是在使用parseInt()的时候报了个错误，奇怪的是该方法转化01,02…07都没问题，但08,09却转化为0。在www.yahoo.cn上搜索，得到如下一位仁兄的文章，才恍然大雾，原来parseInt()有2个参数，第2个参数指出要转化的进制，如果第1个参数是0开头，却又没有指定第2个参数的进制，则该函数会默认为要转化为8进制，所以从08，09就转化为了0.

from http://www.webjx.com
将如下代码置于你的父页面中，而后在父页面的iframe中通过onload事件调用这个方法：
var getFFVersion = navigator.userAgent.substring(navigator.userAgent.indexOf(”Firefox”)).split(”/”)[1];
//extra height in px to add to iframe in FireFox 1.0+ browsers
var FFextraHeight = getFFVersion >= 0.1 ? 16 : 0;
// iframename 由你的iframe的name属性指定
function dyniframesize(iframename)
{
var pTar = null;
if (document.getElementById)
{
pTar = document.getElementById(iframename);
}
else
{
eval(’pTar = ‘ + iframename + ‘;’);
}
if (pTar && !window.opera)
{
//begin resizing iframe
pTar.style.display=”block”;
alert(pTar.contentDocument.body.offsetHeight);
alert(pTar.contentDocument.body.offsetWidth);
if (pTar.contentDocument && pTar.contentDocument.body.offsetHeight && pTar.contentDocument.body.offsetWidth)
{
//ns6 syntax
pTar.height = pTar.contentDocument.body.offsetHeight + FFextraHeight [...]
