Question

我正在尝试在数据库中有新内容时仅在页面上重新加载div标记

在Ajax中我测试新内容：

function adshandler() {
var d = new Date();
var cache = d.getTime();
$.getJSON("check_time.php?cache=" + cache, function(update) {
    if (update.count === true) {
        //location.reload();
        $('#slideshow').reload();
    }
}); 
} 
setInterval(adshandler, 10000);

div与ajax在同一页面上：

//Monday Afternoon
if ($dayofweek == "Monday" && $timeofday >= "12:00:00" && $timeofday <= "16:59:59"){
//Monday afternoon timeslot
echo "<div id='slideshow'>";
$stma= $conn->prepare("SELECT `Monday_Afternoon`
FROM `Client_Ads`");
$stma->execute();
while($resultst = $stma-> fetch()){
$mondayafternoonlist = $resultst["Monday_Afternoon"];
echo "<div class='slideshow'>";
echo "<img src='/$mondayafternoonlist'>";
echo "</div>";
}
echo "</div>";
}

有div with a similar个and个, each one behind an个and个$('#slideshow').reload();个{if}} if if语句，具体取决于星期几等。

我的$('#slideshow').load();无效？我也试过- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self performSegueWithIdentifier:@"showRecipeDetail" sender:[YOUR_ARRAY objectAtIndex:indexPath.row]]; } - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if ([segue.identifier isEqualToString:@"showRecipeDetail"]) { member_details *destViewController = segue.destinationViewController; destViewController.hello = sender; } }。

＆lt; p＆gt;您可以使用＆lt; code＆gt; .load（）＆lt; / code＆gt;来实现它。功能很少。以下是一个工作示例。＆lt; / p＆gt; ＆lt; pre＆gt;＆lt; code＆gt;＆lt; script src =＆＃34; https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"＆gt;＆lt; /脚本＆GT; ＆LT;脚本＆GT; function changeDate（）{ $（＆＃34;＃d2p＆＃34;）。load（location.href +＆＃34;＃d2＆＃34;）; } ＆LT; /脚本＆GT; ＆lt; div id =＆＃34; d1p＆＃34;＆gt; ＆lt; div id =＆＃34; d1＆＃34;＆gt; ＆lt;？php echo date（＆＃34; H：i：s＆＃34;）; ？＆GT; ＆LT; / DIV＆GT; ＆LT; / DIV＆GT; ＆LT; /代码＆GT;＆LT; /预＆GT; ＆lt; p＆gt;这是＆lt; code＆gt; DIV＆lt; / code＆gt;在此页面上部分点击按钮即可刷新。＆lt; / p＆gt; ＆lt; pre＆gt;＆lt; code＆gt;＆lt; div id =＆＃34; d2p＆＃34;＆gt; ＆lt; div id =＆＃34; d2＆＃34;＆gt; ＆lt;？php echo date（＆＃34; H：i：s＆＃34;）; ？＆GT; ＆LT; / DIV＆GT; ＆LT; / DIV＆GT; ＆lt; button onclick =＆＃34; changeDate（）;＆＃34;＆gt;更改日期＆lt; / button＆gt; ＆LT; /代码＆GT;＆LT; /预＆GT; ＆lt; p＆gt;这是演示＆lt; a href =＆＃34; http：//javascriptsolution.com/load-div-without-refreshing-entire-page/" rel =＆＃34; nofollow＆＃34;＆gt;加载div而不刷新整个页面＆lt; / a＆gt;＆lt; / p＆gt;

function adshandler() {
var d = new Date();
var cache = d.getTime();
$.getJSON("check_time.php?cache=" + cache, function(update) {
if (update.count === true) {
    //location.reload();
   $("#slideshow").load(location.href + " #slideshow");
}
}); 
} 
setInterval(adshandler, 10000);

Div标签没有重新加载
