Native ajax waterfall stream demo sharing (mandatory), ajax waterfall demo is mandatory

Recently, I heard from my friends that there are a lot of waterfall streams, so I will study it myself. A simple native demo will be shared with you...

There are three simple documents with detailed notes: img, ajax. php, demo. php

WhereImgPut the image 1.jpg1_2.jpg1_3.jpg in the folder ....

Ajax. php page

<? Php // simulate reading data from the database $ arr = array (); $ op = opendir ('. /img '); // open the directory // read the directory while cyclically ($ file = readdir ($ op ))! = False) {// filter point and dot if ($ file = '. '| $ file = '.. ') {continue;} $ arr [] = $ file;} closedir ($ op); // close the echo json_encode ($ arr) Directory );

Demo.html page

<! DOCTYPE html> 
The above native ajax waterfall stream demo (which is a must-read Article) is all the content shared by the editor. I hope you can give us a reference and provide more support to the customer's house.
