点击button时 如果验证错误则显示错误提示的span
现在 由于写了 onmouseout onmousedown 点击的时候就验证 但button 不会验证

图片button如何写？写要判断才跳转？

探讨

为什么不会验证啊。。<input type="image" src="images/realname_submit.gif" onclick='...'/>
这样不行？

因为前面用 onmouseout onmousedown所以 onclick不知道如何写
难道还要再写一次？

[解决办法]
<input onclick="funSubmit()" type="image" src="images/realname_submit.gif" />

function funSubmit(){
document.forms["Form1"].action="目标页面";
document.forms["Form1"].submit();
}
