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

你这代码是啥问题 后台获取不到还是啥？说得具体点。

HTML代码

<button class="btn btn-success btn-sm" id="post-reply"><i class="fa fa-paper-plane"></i> 发送</button>

//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');   // 单击按钮之后 按钮是disabled 禁止的     clearChatTimers(0);         //index.php?do=webim&action=send_messages    POST 到 后端处理       //  php返回 json数据  {"msg":"\u53d1\u9001\u6210\u529f","status":"1","data":[]}     /*        我对js实在不行，   不知php 如何获取 post 数据   */              $.post('index.php?do=webim',{action:'send_messages',uid:uid,sMessage:message}, function(json) {            if(json.status == '1'){                if($('.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');}

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

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

谢了，我以为 action 是GET参数
