Why Are My Relative Image Paths Broken in External JavaScript Files After Deployment?

Relative Paths in Javascript in an External File

In the given question, the user is experiencing issues with image pathing in an external JavaScript file when deployed to a virtual directory. While the paths work fine in a local development environment, they fail when deployed using '../' or absolute paths like '/Images/filters_collapse.jpg'.

The key understanding here is that paths in external .js files are relative to the page they are included in. Hence, the user should use paths relative to the page where the JavaScript file is referenced, instead of the actual location of the .js file.

As a solution, the user can create a JavaScript variable that specifies the image path, such as:

var imagePath = '../Images/';

By using this variable, the user can ensure that the image paths are correctly resolved regardless of the location of the external JavaScript file. For example, the code below will use the variable to set the background image of an element:

$("#toggle").click(function() {
    if (left.width() > 0) {
        AnimateNav(left, right, 0);
        $(this).css("background", "url(" + imagePath + "filters_expand.jpg")");
    }
    else {
        AnimateNav(left, right, 170);
        $(this).css("background", "url(" + imagePath + "filters_collapse.jpg")");
    }
});
