Question

I need help
I’m using EJS javasript template to write a code snippet two check a radio button depending on data returned from the server. Let say the server returns a json (named my_data) and here is my code

<input type="radio" name="is_public" value=1 <% if(my_data.is_public){ %> <%='checked' %> <% } %> />Public
<input type="radio" name="is_public" value=0 <% if(!my_data.is_public){ %> <%='checked' %> <% } %> />Private

But it doesnt work! the Public is always checked although my_data.is_public = 0.

Any one can help?

btw, are there the way to “echo” a text like this in EJS:

<input type="radio" name="is_public" value=1 <% if(my_data.is_public){ echo 'checked' } %> />Public

Never used EJS, but from experience from other templating engines, this should work:

<input type="radio" name="is_public" value=1 <% if(my_data.is_public){ %> checked="checked" <% } %> />Public
<input type="radio" name="is_public" value=0 <% if(!my_data.is_public){ %> checked="checked" <% } %> />Private

When you say <%=, you are to output the result of a JavaScript evaluation that follows. E.g. <%= a %> should output the contents of variable a at that time.

There’s no need for explicit echo in templates – anything outside <% %> should be echoed by default, of course considering that some blocks are conditionally echoed, like the above if, or may be multiplied when using loops, etc.
