$handle = opendir($imageDir);
while (($imgPath = readdir($handle)) !== false) if (

closedir($handle);
?>
<!-- #slideShow --></div>
<script type="text/javascript" src="slideShow.js"></script>
错误在线:
) echo '
) 后出现意外回显
那么，我应该在哪里添加其余的代码呢？我有一个 javascript 函数和一个 css 代码。我应该将它们添加到同一个 php 文件中吗？如果有，在哪里？在html代码之后？里面的html代码？
这是java脚本代码:
(function(d) {
// user defines
var
swapHours = 0,
swapMinutes = 0,
swapSeconds = 5,
swapTotal = (swapHours * 60 + swapMinutes) * 60 + swapSeconds,
loopSlideShow = true;
// some handy helper functions
function classExists(e, className) {
return RegExp('(\\s|^)' + className + '(\\s|$)').test(e.className);
}
function classAdd(e, className) {
if (classExists(e, className) return false;
e.className += (e.className ? ' ' : '') + className;
return true;
}
function classRemove(e, className) {
if (!classExists(e, className)) return false;
e.className = e.className.replace(
new RegExp('(\\s|^)' + n + '(\\s|$)'), ' '
) . replace(/^\s+|\s+$/g,'');
return true;
}
function textReplace(e, newtext) {
if (d.innerText) e.innerText = newText;
else e.textContent = newText;
}
function nodeFirst(e) {
e = e.firstChild;
while (e && e.nodeType != 1) e = e.nextSibling;
return e;
}
function nodeLast(e) {
e = e.lastChild;
while (e && e.nodeType != 1) e = e.prevSibling;
return e;
}
function nodeNext(e) {
while (e) if ((e = e.nextSibling).nodeType == 1) return e;
return null;
}
function nodePrev(e) {
while (e) if ((e = e.prevSibling).nodeType == 1) return e;
return null;
}
// slideShow setup
var
slideShow = d.getElementById('slideShow'),
slideCounter = d.getElementById('slideCounter'),
firstSlide = nodeFirst(slideShow),
lastSlide = nodeLast(slideShow),
currentSlide = firstSlide,
swapCounter;
classAdd(slideShow, 'ss_scripted');
classAdd(currentSlide, 'ss_show');
// slideShow functions
function showCounter() {
textReplace(slideCounter,
Math.floor(swapCounter / 3600) + ':' +
(Math.floor(swapCounter / 60) % 60) + ':' +
swapCounter % 60
);
}
function resetCounter() {
swapCounter = swapTotal;
showCounter();
}
function makeSlide(newSlide) {
classRemove(currentSlide, 'ss_show);
currentSlide = newSlide;
classAdd(currentSlide, 'ss_show');
}
function nextSlide() {
resetCounter();
var newSlide = nodeNext(currentSlide);
if (newSlide) makeSlide(newSlide);
else if (loopSlideShow) makeSlide(firstSlide);
}
function prevSlide() {
resetCounter();
var newSlide = nodePrev(currentSlide);
if (newSlide) makeSlide(newSlide);
else if (loopSlideShow) makeSlide(lastSlide);
}
function slideUpdate() {
if (swapCounter--) showCounter(); else nextSlide();
}
function startSlideShow() {
resetCounter();
setInterval(slideUpdate, 1000);
}
// wait for onload to actually start the countdown
if (window.eventListener) w.addEventListener('load', startSlideShow, false);
else w.addEventListener('onload', startSlideShow);
})(document);
这是CSS代码:
.ss_scripted img { display:none; }
.ss_scripted .ss_show { display:block; }
最佳答案
问题是你少了一个")"
尝试
while (($imgPath = readdir($handle)) !== false) if (
in_array(
strtolower(pathinfo($imgPath, PATHINFO_EXTENSION)),
$allowed_types
)) echo '
<img src="', $imageDir, '/', $imagePath, '" alt="slide" />';
closedir($handle);
)) echo ' 第一个来自 in_array() 第二个来自 if()
希望对您有所帮助! :D
关于javascript - 我有一个 php 文件，在里面的代码中有一个错误，我不知道如何修复它？以及在哪里添加其余代码，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26718035/
