    How to "echo" a text in EJS (a javascript template) to check a radio button - Stack Overflow

    programmeradmin4浏览0评论

    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

    EJS is a simple and easy to use engine, and does not need to put too much learning cost on the template. If you look at the source, you'll find something funny.

    // the same as echo string
__append(string)

    So:

    <input type="radio" name="is_public" value=1 <% if(my_data.is_public){ __append('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.
