写一行到javascript文件

Question

Im using a array to display some images in a website:

var paintingImages;
paintingImages =
    [
        {
            url: 'images/objects/ron.jpg',
            alt: 'ron'
        }
    ];

This js code is written in paintings.js and my main js code is written in the file main.js

I have made this website for a artist and I want to give him the opportunity to login and add pictures to his website. I'm not that good with php, but adding images to a ftp in a folder is no problem.

Because I'm using a array for retrieving the images, I need to be able to add items to the array. This is the part where I'm stuck. I don't know how to edit a existing js file, so the next time I open the website, the items (images) will been shown.

Activexobject is not a option because it's only possible in IE.

In summary:

• I need to add a item to a array
• I need to save this into the file, so the next time the website opens, it will be shown
• I'm not verry good with php, I prefer javascript
• Can't use Activexobject because of the use of multiple browsers

You can not simply modify a javascript file sitting on the server from browser side javascript. You need to implement some server side logic.

If you don't like PHP, but like JavaScript, check out NodeJS for example. With Node you should be able to build some lightweight serverside logic to modify your json array file with additional images.
