Question

这是我的代码

<script type="text/javascript">
window.onload=change;
var i=0 ;
function change()
{
    var images = new Array('1','2','3','4','5','6');
    document.getElementById('baner').src = obrazy[i];
    i++
    if (i == images.length)
    {
        i=0;
    }
}
setTimeout(change,1000);
</script>

我想制作简单的滑块但是setTimeout只做了2次我的脚本。是的，我有id baner的元素。我不知道那有什么问题。

您只在change处理window.onload两次，一次在setInterval的处理程序中，一次在超时1秒后。

您可能正在寻找setTimeout 而不是window.onload = function() { var i=0 ; function change() { var images = new Array('1','2','3','4','5','6'); document.getElementById('baner').src = obrazy[i]; i++; if (i == images.length) { i=0; } } setInterval(change,1000); change(); }：

                "message": "<message>The file is not a Revit file or is not a supported version.</message>"
            },
            {
                "type": "error",
                "message": "Possibly recoverable warning exit code from extractor: -536870935",

            }
        ],

您应该使用调用函数的setInterval()方法或以指定的时间间隔（以毫秒为单位）计算表达式。

<script type="text/javascript">
window.onload=change;
var i=0 ;
function change()
{
    var images = new Array('1','2','3','4','5','6');
    document.getElementById('baner').src = obrazy[i];
    i++
    if (i == images.length)
    {
        i=0;
    }
}
setInterval(change,1000);
</script>

setTimeout()方法在指定的毫秒数后调用函数并停止。

setTimeout（）只工作2次
