ws = new WebSocket(‘ws://192.168.150.53:8080/websocket’);
ws.send(“111”);

因为ws连接还没有建立成功，不能在new完后直接跟着send。

js代码：

<script>

    var interval = 1000;
    var send = function (ws,message, callback){
            waitForConnection(ws,function(){
            ws.send(message); 
            if(typeof callback!=='undefined'){
                callback(); 
            } 
        },interval); 
    }; 
    var waitForConnection = function(ws,callback,interval){
        if(ws.readyState === 1){
            callback(); 
        } else {
        
        //可选：实现间隔在这里
        setTimeout(function(){
                waitForConnection(ws,callback,interval); 
            },interval); 
        } 
    }; 



</script>

// 阻塞等待ws连接状态完成
send(ws,messageJson,function(){
console.log("send callback");
$("#log-info div").empty();
$("#log-info div").append("正在查询...").css("color", "#FFFFFF");
})
