 发送

/**

// 清除定时器
function clearChatTimers(id){
	if(id){
		//请除指定用户定时执行
	    if(aPChatTimers[id]){
	    	clearTimeout(aPChatTimers[id]);
	    	loadFlag = false;

/**

 * @returns

function getRecipientIdFromReplyBtn(){
	var uid = $.trim($("#post-reply").attr('data-send-uid'));
	if(uid == undefined||uid ==''){
		uid = false;
	}
	return uid;
}
/**
 * 清空发送的文本内容
 * @returns
 */
function clearInputMessage(){
	$("#edit").val('');
	$("#post-reply").focus();
}

/**

 * @returns
 */
function getInputMessage(){
	var  sMsg = $.trim($("#edit").val());
	if(sMsg == undefined||sMsg ==''){
		sMsg = false;
	}
	return sMsg;
}

//发送信息
 function sendPrivateMessages(){
	 var uid,message;
		 uid = getRecipientIdFromReplyBtn();
		 message 	= getInputMessage();
	 
	 if(message === false){
	 	$('.for-post').popover('show');
		$("#edit").focus(function() {
			$('.for-post').popover('hide');
		});
		 return false;
	 }
	 
 	 $("#post-reply").attr('disabled','disabled');
	 clearChatTimers(0);

        //index.php?do=webim&action=send_messages    POST
	 
   	 $.post('index.php?do=webim',{action:'send_messages',uid:uid,sMessage:message}, function(json) {
   		 if(json.status == '1'){
   		 	if($('.dialog-comment-list').find('li').length >0){
   		 		var _scrollHeight = $('.dialog-comment-list').find('li').last().offset().top;
   		 		$("#post-reply").closest('.site-im-dialog').find('.dialog-comment-list').animate({zoom:1},function(){
		    		$(".dialog-comment-list-box").data('jsp').scrollTo(0, _scrollHeight);
		    	});
   		 	}

    		 $("#post-reply").removeAttr('disabled');
    		 clearInputMessage();
    		 clearChatTimers(0);
 		     getPrivateMessages(uid);
   		 }else{
   			 tipsOp(json.msg,'error');
   			 $("#post-reply").removeAttr('disabled');
   		 }
   		 	
     },'json');
}

返回 {"msg":"\u53d1\u9001\u6210\u529f","status":"1","data":[]}

单击发送或 Ctrl+Enter 按钮不抬起 （如图）







如何才能单击发送按钮或者按CTRL+ENTER 把数据POST到php处理 求PHP代码





------解决思路----------------------
执行 $.post('index.php?do=webim',{action:'send_messages',uid:uid,sMessage:message} ... 后
php 得到
$_GET['do'] 为 webim
$_POST['action'] 为 send_messages
$_POST['uid'] 为 uid 的值
$_POST['sMessage'] 为 message 的值
