ws.onopen = function () {
    console.log("ws connected!");
};
ws.onerror = function (e) {
    var strErr = ‘‘;
    for ( var p in e) {
        strErr += p + "=" + e[p]+"
";
    }
    console.log("ws error occured!
"+strErr);
};
ws.onclose = function (e) {
    console.log("ws closed! code:["+e.code+"] msg:"+e.reason)
};
ws.onmessage = function (e) {
    var data = JSON.parse(e.data);
};
