Question

您好我正在尝试自动刷新此div标签。它包含一个链接到窗口小部件的外部URL的iframe。我希望它每30秒刷新一次。只是好奇如何做到这一点。

<div id="my-content">
<iframe src="https://discordapp.com/widget?id=*****************&theme=dark" width="350" height="500" allowtransparency="true" frameborder="0"></iframe></div>
</div>

<script>
$(document).ready( function() {
$('div.index-right').eq(0).append($('div#my-content'));
});
</script>

我收到一条未捕获的异常错误，在下面评论过。这适用于在iframe中链接的外部站点，并且没有本地写入的数据以进行更新。 div只需要刷新。

Answer 1

我认为这应该有效，假设您在页面上只有一个iframe。

setInterval(function(){
    $('iframe')[0].contentWindow.location.reload(true);
}, 30 * 1000);

为了帮助您获得安全警告，请尝试以下建议：The frame requesting access has a protocol of "https", the frame being accessed has a protocol of "http". Protocols must match

试试这个：

<p>Enter a number between <strong>0</strong> and <strong>100</strong> and remember your number.</p>
<p>When ready press "Begin" and the computer will try to find your number.</p>
<input id="myNumber" style="width: 100px" />
<button id="guess" onclick="compGuess">Begin</button>

function compGuess()
{
    if (document.getElementById("myNumber").value < 0 || document.getElementById("myNumber").value > 100 )
    {
        alert("Please enter a number between 0 and 100.");
    } 
    else
    {
        var start = 0;
        var stop  = 100;
        var middle = Math.floor(start + stop / 2);
        var guess = document.getElementById("myNumber").value;

        if (middle == guess)
        {
            alert("Your number is: " + middle);
        }
        else
        {
            while (start <= stop)
            {
                if (middle < guess)
                {
                    start = middle + 1;

                }
                else if (middle > guess)
                {
                    stop = middle - 1;
                }
                else
                {
                    alert(middle); 
                }
                alert("Your answer is : " + middle);
            }
        }
    }

这只会使用名为 my-content 的ID刷新div。
