我使用的是 netbeans 8.0.1，php 版本是 5.3
我有一个 php 文件:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

<p>
This slideshow requires JavaScript for full functionality. Please either enable it or use a browser capable of it for the "proper" experience. Below are the images that would have been shown in said slideshow.
</p>
</noscript>
<div id="slideShow">
<img src="Images/radar000025.Gif" alt="slide" />
<img src="Images/radar000203.Gif" alt="slide" />
<?php
$dir = 'Images';
$files1 = scandir($dir);
?>
<!-- #slideShow --></div>
<script type="text/javascript" src="slideshow.js"></script>
</body></html>
对于测试，我仅使用两个图像:
<img src="Images/radar000025.Gif" alt="slide" />
<img src="Images/radar000203.Gif" alt="slide" />
现在，在本例中，图像位于本地目录中，然后我使用 xampp v3.2.1 启动 apache 服务器。
但稍后图像将从网站服务器上的目录中读取，如下所示:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
//$allowed_types="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$) |(\.Gif$)";
$allowed_types = array('png','jpg','jpeg','gif');
$imageDir = 'files/radar-simulation-files';
/*
Assumes this .php is being run from the http root on the same
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, '/', $imgPath, '" alt="slide" />';
closedir($handle);
?>
当图像位于非本地服务器目录上以及所有代码位于同一个文件上时，我使用它来将图像添加到数组变量中。
但现在我将代码分离到一些文件中。 我有另一个文件 javascript 文件，我想将数组变量从 php 文件传递到 javascript 文件并在 javascript 文件上使用它。
当图像位于本地/服务器目录时，如何将 php 文件中的图像添加到数组变量？
那么如何传递变量并在javascript文件中使用它呢？
这是 JavaScript 文件代码:
(function(d, w) {
// 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|$)').test(e.className);
}
function classAdd(e, className) {
if (classExists(e, className)) return false;
e.className += (e.className ? ' ' : '') + className;
return true;
}
function classRemove(e, className) {
if (!classExists(e, className)) return false;
e.className = e.className.replace(
new RegExp('(\\s|^)' + className + '(\\s|$)'), ' '
) . replace(/^\s+|\s+$/g,'');
return true;
}
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.previousSibling;
return e;
}
function nodeNext(e) {
while (e = e.nextSibling) if (e.nodeType == 1) return e;
return null;
}
function nodePrev(e) {
while (e = e.previousSibling) if (e.nodeType == 1) return e;
return null;
}
function nodeFlush(e) {
while (e.firstChild) e.removeChild(e.firstChild);
}
function nodeReplace(e, newNode) {
nodeFlush(e);
e.appendChild(
typeof newNode == 'object' ? newNode : d.createTextNode(newNode)
);
}
function make(tagName, child, attribs, parent) {
var e = d.createElement(tagName);
if (child) e.appendChild(
typeof child == 'object' ? child : d.createTextNode(child)
);
if (attribs) for (var i in attribs) e[i] = attribs[i];
if (parent) parent.appendChild(e);
return e;
}
function prevent(e, deselect) {
e.cancelBubble = true;
if (e.stopPropagation) e.stopPropagation();
if (e.preventDefault) e.preventDefault();
e.returnValue = false;
if (deselect) {
if (w.getSelection) w.getSelection().removeAllRanges();
if (d.selection) d.selection.empty();
}
}
function controlEvent(e, handler) {
handler();
e = e || window.event;
prevent(e, true);
}
function clockFormat(value) {
value = String(Math.floor(value));
while (value.length < 2) value = '0' + value;
return value;
}
// slideShow functions
function showCounter() {
nodeReplace(slideCounter,
clockFormat(swapCounter / 3600) + ':' +
clockFormat((swapCounter / 60) % 60) + ':' +
clockFormat(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);
}
// slideShow setup
var
slideShow = d.getElementById('slideShow'),
slideCounter = make('div', false, { id : 'slideCounter' }),
slideControls = make('div', false, { id : 'slideControls' }),
slidePrev = make('a', 'Previous Slide', {
onclick : function(e) { controlEvent(e, prevSlide); },
className : 'previous',
href : '#'
}, slideControls),
slideNext = make('a', 'Next Slide', {
onclick : function(e) { controlEvent(e, nextSlide); },
className : 'next',
href : '#'
}, slideControls),
firstSlide = nodeFirst(slideShow),
lastSlide = nodeLast(slideShow),
currentSlide = firstSlide,
swapCounter;
slideShow.parentNode.insertBefore(slideCounter, slideShow);
slideShow.parentNode.insertBefore(slideControls, slideShow.nextSibling);
classAdd(slideShow, 'ss_scripted');
classAdd(currentSlide, 'ss_show');
// wait for onload to actually start the countdown
if (w.addEventListener) w.addEventListener('load', startSlideShow, false);
else w.attachEvent('onload', startSlideShow);
})(document, window);
最佳答案
解决方案就在我眼前。 只需替换这两行:
<img src="Images/radar000025.Gif" alt="slide" />
<img src="Images/radar000203.Gif" alt="slide" />
使用 php 脚本:
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
$allowed_types = array('png','jpg','jpeg','gif');
$imageDir = 'files/radar-simulation-files';
$handle = opendir($imageDir);
while (($imgPath = readdir($handle)) !== false)
if ( in_array(strtolower(pathinfo($imgPath, PATHINFO_EXTENSION)), $allowed_types ))
echo '<img src="', $imageDir, '/', $imgPath, '" alt="slide" />';
closedir($handle);
?>
将 imageDir 更改为“Images”，这就是它在使用 xampp 时适用于本地服务器，当我将文件上传到我的主机 ipage.com 时，我只需将 imageDir 更改为“files/radar-simulation-”文件就这么简单。
关于javascript - 如何将本地/服务器目录中的所有图像添加到数组并在另一个文件上使用数组 var？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26754210/
