如何使用jquery或javascript在网页上显示带有多个缩略图的pdf文件?

我正在从事一个项目，在一个页面上，我显示了多个pdf缩略图/图像，这些缩略图/图像是从我的系统目录中动态加载的。每个缩略图在其他目录中都有相应的 pdf 文件。

因此，当我单击网页上的任何一个缩略图/图像时，相应的pdf文件应该在新窗口中打开，该窗口也存储在系统上的不同目录中。我已经使用php来开发我的网页。

<?php
//FOR PDF
$pdf_directory = "pdf/";// PDF file directory
$p = glob($pdf_directory."*");
foreach($p as $portable) {  
$file=basename($portable,"*.pdf");
$without_ex1 = pathinfo($file, PATHINFO_FILENAME); 
//FOR THUMBNAIL
$pdfimg_directory = "pdfimage/";// THUMBNAIL Directory
$pi = glob($pdfimg_directory."*");
$file2 = basename($b,"*.pdf");
$without_ex2 = pathinfo($file2, PATHINFO_FILENAME); //trim .jgp
if($without_ex1===$without_ex2) {
foreach($pi as $thumbImages) {
echo '<a href="'.$portable.'"<img id = "img_id" src="'.$thumbImages.'" style="width: 100; height:100;">';
}
}
}
?>

我得到了想要的输出。谢谢你的帮助。分享了下面的代码。

<?php 
$pdf = "pdf/";      //pdf directory
$pdfimg = "pdfimage/"; //pdf thumbnail directory. Used imagemagick to convert pdf to thumbnail
$all_files = glob($pdfimg."*"); 
$all_pdf = glob($pdf."*pdf");
for ($i=0;$i<count($all_files);$i++){
$pdf_name = $all_pdf[$i];
$a = ltrim($pdf_name,"pdf/"); //display pdf name
$image_name = $all_files[$i]; 
echo '<a href="'.$pdf_name.'"><img src="'.$image_name .'" alt="'.$image_name.'" title="'.$a.'"style="height:100; width:100;display:inline;animation: moveSlideShow 1s linear infinite; margin-top:-17px; margin-left:5px;"/></a>';
}   
?>

您的问题没有太多代码或信息，但我认为这就是您正在寻找的。我认为你想要这个，但对于 pdf 文件也是如此，我想你可以编辑代码并使其适合 pdf。以下是上面链接的代码片段：

function openModal() {
document.getElementById('myModal').style.display = "block";
}
function closeModal() {
document.getElementById('myModal').style.display = "none";
}
var slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("demo");
var captionText = document.getElementById("caption");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
captionText.innerHTML = dots[slideIndex-1].alt;
}
