使用jQuery变量添加rails image_tag

Question

I am adding a rails image_tag with jQueryand I am trying to put a jQueryvariable in the image_tag.

var variable = 0;
$(targetPlayerElement).html('<%= image_tag @users[variable].profile_picture 

I am getting undefined local variable or method `variable' error. What is the correct syntax to do this if you even can. thank you for all the help.

Answer 1

What about storing the content of your variable as pure Ruby and then use it in your image tag?

An example:

<div id="content"></div>
<% image = 'http://placekitten.com.s3.amazonaws.com/homepage-samples/408/287.jpg' %>
<script>$('#content').html('<%= image_tag image %>')</script>

Answer 2

You're mixing two things there, the var variable = 0 is javascript and the <%= image_tag @users[variable].profile_picture is ruby. If you want them to be used together, the variable has to be parsed by js like this.

var variable = 0;
$(targetPlayerElement).html("<%= image_tag @users[" + variable + "].profile_picture %>")
