iterating through image folder using javascript and adding the result in HTML

Question

Hey I am trying to figure out a way for me to add some media(images and videos) to my webpage. I have a section where I add only images and videos, and it is HTML-based So I thought I could find a way to just create one folder for each section, add all the media in that folder, and then let Javascript do the work. This is the script I have come up with so far.

Javascript

var files = {'jpg':4};
var pageName = "Wimoveh";
for (var ext in files){
for (var i = 0; i < files[ext]; i++){
    var src = "Images/GalleryOne" + pageName + "-" + (i+1) + "." + ext;}
}

This script looks in the folder GalleryOne for the picture with name Wimoveh with a '-' as separator and then iterates through all the content that matches that name and extension. What I dont know is how to output the result in my HTML.

Inside your loop:

var img = new Image(); 
img.src = src;
containerElement.appendChild(img);

Where containerElement is a reference to the html element you want to add the images to. (note that you'll need to delay until the dom has loaded to do so)

Thanks, about the delay, does it have anything to do with document.ready?

generalhenry Over a year ago

Yes, document.ready is the same thing, it runs when the dom is parsed. you can use jQuery $(document).ready(myfunc); jQuery $(myfunc); or vanilla window.onload = myfunc;

As Generalhenry stated in his post:

Where containerElement is a reference to the html element you want to add the images to. (note that you'll need to delay until the dom has loaded to do so)

The containerElement is what ever HTML element you want it to be. For example:

<HTML>
<BODY>
    <div class="photos">
        Your images would populate here.
    </div>
</BODY>
</HTML>

Every time loop through your script when the code reaches photos.appendChild(IMG) your page will add an image to that div class.

You are a bit late... Did you use IE for this?

Yah I figured but there was an unanswered portion so I thought I would answer that. "Did you use IE for this"... Um what?

xdevs23 Over a year ago

Yeah your answer is actually good but surely not useful anymore for who is asking. But keep it here because someone could need it later. IE = Internet Explorer.

Yah I know you mean Internet Explorer. What are you asking? Why? I'm on my Android phone stack overflow app.
