Hi there,

Hope someone can help me on this. I really need help.

I have a javascript for a rotating image, whereby a total of 10 images will change automatically in every 3 seconds. It works well in a .html page, however it doesn't work in a .php page. In a .php page, only the first image appears, then it is stagnant, the rest of the images do not appear.

Can anyone please advise if the following script has any issue whereby it will not be executed properly when it's in a .php page? or, what's the reason that it couldn't work in a .php page?

Any advice is very much appreciated. Thank you so much.

My script is as below:

<script type="text/javascript">
img1 = new Image(); img1.src = "images/f95ce056343b3dbdb6606096b2123494_ybx7.png";
img2 = new Image(); img2.src = "images/6c714872e4c66a789b21e88fd90f6f03.png";
img3 = new Image(); img3.src = "images/0b2db57ccbd11c6c7a52cc10ad9aa950.png";
img4 = new Image(); img4.src = "images/9f932a67ed4a1c3dd83948b8b7afb052.png";
img5 = new Image(); img5.src = "images/d6085b0ae37acce9f85899a0fb66879f.png";
img6 = new Image(); img6.src = "images/c865d6c72544cb2590ef922c02f1b9eb.png";
img7 = new Image(); img7.src = "images/7b8e0e999dc94fe436e86b4dedfcb8ed.png";
img8 = new Image(); img8.src = "images/c5c25bc26aced3da5e5595734ca1d35d.png";
img9 = new Image(); img9.src = "images/9dd72de17f11cd33f4e9a197ddaaf417.png";
img10 = new Image(); img10.src = "images/cb69f5ea9146d20b6f52bad0e2a5c179.png";
// add as many images as you want
var howManyPics = 10; //set this to the number of pictures you have
var delay = 3; // set this to the number of seconds between each picture
//don't touch anything below here
var pic = 1;
function changePic(){
pic = (pic==howManyPics)?1:pic+1;
document.images['img'].src = eval('img'+pic+'.src');
}
</script>
</head>
<body onload="setInterval('changePic()', delay*1000);">
<img name="img" src="images/f95ce056343b3dbdb6606096b2123494_ybx7.png">

Its not the problem of .php or .html. I think you had done mistake in your code, use firebug in firefox it will show you error... gud luck

Hi Yashashya,

Thanks a lot for your advice.

I quickly used firefox to check if there is any error but none is shown.

The question arised because I inserted the same code at two of my pages - one is at Home page (php page), and another one at Contact page (html page). The rotating image function is working fine at the Contact page, i.e. images are changing automatically every 3 seconds. However, for Home page, only the first image is shown and the rest of the images do not appear at all.

You may go to http://www.cisspr.com to view the rotating image. At both "Home" (on top of the page - the first image of "We perform testing for electromagnetic fields from cellular & broadcast tower) and "Contact" pages (at the bottom of the page).

Really appreciate your help.

I'm not very good at javascript, but I tried to test the pages with Opera. It shows a number of errors that just have to do with the CSS, both in Home and Contact. But in Home there are some additional errors (according to Opera):

console.warn
duplicate in.js loaded, any parameters will be ignored

There are lots of those about Twitter and Google. Also I noted that with Firefox the loading of the page never seems to end. I hope this will be a clue for you to find the error.

@matildacheng--

If you are still having issues between the HTML page and PHP code, keep in mind that when you call the PHP page from a browser, the web server returns HTML code, not PHP. So, you can easily connect to both pages, and in your browser, right click and view source. Check to see what the difference is. Its likely to be a syntax error on the php page.

In addition to what JorgeM said above you can try running the pages in Google Chrome and right click on the slideshow and go down to "Inspect element" it will show you any activity that is going on in the page, then on the bar that shows up go over to console and it will show you all errors on the page.

And as a sidenote there is a really good jquery slideshow tutorial Here, the creator of the page is currently redecorating the page so its a bit wonky at the moment, but you can still read through the tutorial.

This problem is not because of extension.
As discussed above use "Inspect element" of google chrome to see problem.

Also you can use debug mode of IE i.e.,by opening it in IE and press "F12" and then you can see if there is any javascript error.Select Script tag there and check.

Well you seem to have changed ext to html.

There were no errors that I could see on the home page - BUT first load took an extremely long time.

THe contacts page was strewn with errors from the widget box:

Thank you very much to all of you for your help. I followed the advice to remove some problematic plugins at my page which caused the long loading time. The rotating images are now working at my homepage.

Once again, thank you so much and really appreciate all of you for your replies.
