我的聊天室中的文本框用的是textarea，本来按提交按钮就可以提交了，可我又加了个按ctrl+enter来提交，这是我在一个小程序中试的没问题的，也就是在我那个小程序中两种都可以提交，可在我的聊天室中就不行了，只能通过ctrl+enter来提交，如果你用提交按钮来提交的话，它就会一直提交是你上一次用ctrl+enter提交的内容，让我很是郁闷，我把一段比较关键的代码帖出来，请高手指教，多谢了：
function send(){
if(window.event.ctrlKey && window.event.keyCode==13){
var post_msg=document.af.post_msg.value
var msg=document.af.msg.value
var zh=document.af.zh.value
while(post_msg.indexOf(">") != -1 || post_msg.indexOf("<") != -1 || post_msg.indexOf(" ") != -1 || post_msg.indexOf("　") != -1 || post_msg.indexOf(",") != -1 || msg.indexOf(" ") != -1 || msg.indexOf("　") != -1 || msg.indexOf(",") != -1 || msg.indexOf("<") != -1 || msg.indexOf(">") != -1 || zh.indexOf("操") != -1 || msg.indexOf("操") != -1){
post_msg = post_msg.replace(" ","");
post_msg = post_msg.replace("　","");
post_msg = post_msg.replace(",","");
post_msg = post_msg.replace("<","<")
post_msg = post_msg.replace(">",">")
msg = msg.replace(" ","");
msg = msg.replace("　","");
msg = msg.replace(",","");
msg = msg.replace("<","<")
msg = msg.replace(">",">")
msg = msg.replace("操","*")
zh = zh.replace("操","*")
}
if (msg==''){alert('请输入发言或动作！');document.af.msg.focus();return false;}
if (msg==post_msg){alert('请不要重复发言！！');document.af.msg.focus();return false;}
else{
this.document.af.post_msg.value=msg;
this.document.af.zh.value=msg;
this.document.af.submit();
this.document.af.msg.value='';
this.document.af.tu.value='0';
setTimeout('document.af.Submit.disabled=0',3000);
document.af.msg.focus();

}
}
}
