提供一系列提示.然后将5秒钟的interval更改div的内容.我假设您想要随机提示.

Make an array of tips. Then make a interval of 5 seconds that change the div's content. I assume you want random tips.

在jsFiddle上查看此示例.

See this example on jsFiddle.

var tips = [
    "Tip 01",
    "Tip 02",
    "Tip 03",
    "Tip 04",
    "Tip 05",
    "Tip 06",
    "Tip 07",
    "Tip 08",
    "Tip 09"
];

// get a random index, get the value from array and
// change the div content
setInterval(function() {
    var i = Math.round((Math.random()) * tips.length);
    if (i == tips.length) --i;
    $("#tip").html(tips[i]);
}, 5 * 1000);
