------解决方案--------------------参考
<script language= "javascript ">
function check(zt,area)
{
zt = zt.replace(/ /g, " ");
if(zt== " " || zt.length <3)
{alert( "主题不能为空!或主题过短! ");
document.fom.zt.focus();
return false;}
if(area.length> 5000){
alert( "留言过多! ");
document.fom.area.focus();
return false;}
if(area== " "&&zt== " "&&tp== "http:// "){
alert( "空信息无法发出! ");
document.fom.area.focus();
return false;}
document.all( "ok ").style.display= "none ";
}
</script>
