我有一個PHP文件,我把它叫做爲測試index1.php 在我現在這個代碼的文件:在哪裏以及如何在PHP文件中添加JavaScript代碼和CSS代碼?

$allowed_types = ['png','jpg','jpeg','gif'];
$imageDir = 'files/radar-simulation-files';
/*

domain as the desired image files.
*/
$handle = opendir($imageDir);
while (($imgPath = readdir($handle)) !== false) if (
in_array(
strtolower(pathinfo($imgPath, PATHINFO_EXTENSION)),
$allowed_types
)) echo '
<img src="', $imageDir, '/', $imagePath, '" alt="slide" />';
closedir($handle);
?>
<!-- #slideShow --></div>
<script type="text/javascript" src="slideShow.js"></script>
</body></html>
現在我有這個代碼還JavaScript代碼使用,我不知道在哪裏添加此代碼?
(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);
我想在這行之間添加以下代碼:
<script type="text/javascript" src="slideShow.js"></script>
腳本標記之間。
在腳本標記之間添加此代碼是否正確?
我得到這個代碼的3個錯誤:
就行了:如果(classExists(E,類名)返回false;預期),但發現回
就行了: classRemove(currentSlide,'ss_show);缺少近親報價
上線:currentSlide = newSlide;預期但未找到
最後在哪裏添加CSS代碼?
你是正確的把它放在'script'標籤之間,但是你必須刪除'src'屬性,否則瀏覽器將忽略標籤內的內容,並嘗試下載'src中指定的文件' – danyamachine 2014-11-03 18:14:21
看來你應該對你正在做的工作做一些研究。 http://www.w3schools.com/js/js_whereto.asp – 2014-11-03 18:17:06
