[Go] GO语言实战-实现标题闪烁

window.parent.postMessage(redata);

window.addEventListener('message',function(e){
    var msg=e.data;
    if(msg.type=="message"){
        flashTitle();//标题闪烁
    }
});

var titleTimer,titleNum=0;
var originTitle = document.title;
function flashTitle() {
    titleNum++;
    if (titleNum == 3) {
        titleNum = 1;
    }
    if (titleNum == 1) {
        document.title = '【】' + originTitle;
    }
    if (titleNum == 2) {
        document.title = '【你有一条消息】' + originTitle;
    }
    titleTimer = setTimeout("flashTitle()", 500);
}

window.onfocus = function () {
    clearTimeout(titleTimer);
    document.title = originTitle;
};
