如何基于定时器更改div的内容

做一系列的提示。然后做一个 interval 更改div内容的5秒。我想你需要随机的小费。

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);

见:

• setInterval
• jQuery selectors
• jQuery html

called .setInterval() ,它将每n毫秒运行一次代码。

var $div = $('#myDiv');

var timer = setInterval( function() {
    $div.html( newContent ); // which would reference some dynamic content 
}, 5000);

通过存储 .setInterval() using .clearInterval() .

clearInterval( timer );
