我需要每隔5秒重新加载背景图片,从php文件中提取img-url。像这样:
PHP(我知道如何做php部分):
<?
//mysql connection
//mysql query
echo ('$picurl')
?>
HTML:
<td height="282" style= "background:url(img/frontpage/johana.jpg) no-repeat">
<-- html content -->
</td>

未经测试,但应该采用诀窍(使用JQuery):
setInterval(fetchImage(), 5000);
function fetchImage() {
$.get("/path/to/your.php", function(data){ // "data" is whatever your php script returns
//console.log(data); // for debugging your php response
var imageString = 'url(' + data + ') no-repeat'; // Build your background css string
$('td#yourID').css('background',imageString); // assign the value of imageString to the td's background css property
});
}
您的php文件必须返回单个图像路径。

希望这个帮助:编辑:试试这个:D
<script>
var slideShowNum = 0;
var slideShowSources = ["<? echo ('$picurl') ?>", "<? echo ('$picur2') ?>", "<? echo ('$picur3') ?>", "<? echo ('$picur4') ?>"];
function SlideShowImageChanger() {
slideShowNum++;
if (slideShowNum == 4) {
slideShowNum = 0;
}
var imageSrc = slideShowSources[slideShowNum];
var imageElm = document.getElementById('YourTdId');
imageElm.style.backgroundImage = "url(" + imageSrc + ")";
}
</script>
<td height="282" id="YourTdId" style= "background:url(img/frontpage/johana.jpg) no-repeat">
<-- html content -->
</td>
<script>
setInterval(SlideShowImageChanger, 8000);
</script>

向运输署提供您可以定位的身份证或类别,然后这样的话会让您继续前进:
setInterval(function() {
$.ajax({
url: 'path/to/server/script.php',
success: function(response) {
// This assumes the output of your server script is simply
// an image url
$('#td-id').css('background-image', response);
}
});
}, 5000);

你使用的whit jquery:
setInterval(function() {
// Do something every 2 seconds
}, 2000);
on setinterval执行php页面的异步HTTP(Ajax)请求并使用结果 用http://api.jquery.com/css/设置页面的CSS。
