In my rails application, I have some set of content and image-button (each piece of content has an image). When a user clicks the button, I want to show the respective image.
In my project, I saved all my images under assets/images/preview/id1.png (for example). In my javascript code, when clicking the view-content button i want to change the background image to display the respective image. I want to lookup the image based on the id assigned to that button. How can I achieve this?
How to set that image url for back ground image:
_page2.html.erb
<div class="content">
<table>
<tr>
<td> content about the image </td>
<td> <div id="<%= content[:lable].delete(' ')%>" class="view"> VIEW-IMAGE</div></td>
</tr>
<tr>
<td>content about the image</td>
<td><div id= "<%= content[:lable].delete('')%>" class="view">VIEW-IMAGE</div></td>
</tr>
</table>
content/preview.js
$('.view').click(function (event){
var image = $(this).id
$(this).css("background", "url(image.jpg) no-repeat");
});
});

In content/preview.js
$('.view').click(function (event){
$(this).css("background", "url(sample.png) no-repeat");
});
I tried using the code listed above. It appears the image is not loaded because it searches images in content/sample.png instead of assets/images/sample.png.
Try this
$('.view').click(function (event){
$(this).css("background", "url(assets/images/sample.png) no-repeat");
});
EDIT
In your case if you wish to set the background according to id
of the element, simply modify the code like this:
$('.view').click(function (event){
var id = $(this).attr('id');
$(this).css("background", "url(assets/images/" + id + ".png) no-repeat");
});
