使用JQuery在Ruby on Rails中更改图像

Question

I'm having problems to change an image using JQuery.

The fragment from my hmtl.erb :

<%= image_tag('empty-screen.png', style:'width: 100%', class:'img-responsive center-block', id:'screen-d') %>

Fragment from my javascript :

$("#collapseOne").on('show.bs.collapse',function () {
        $('#screen-d').attr("src","#{asset_path('empty-screen.png')}");
    });

The real problem is that I don't know very well how Rails uses the asset pipeline. I believed that using asset_path would work, but with that code I was just changing the src to #{asset_path('empty-screen.png')} . So I don't really know what to do.

Answer 1

Try

$("#collapseOne").on('show.bs.collapse',function () {
    $('#screen-d').attr("src","<%= asset_path('empty-screen.png') %>");
});

And make sure to add a .erb at the end of your .js file
