defining new variable within jquery template

Question

Is it possible to define a new variable within a jquery template? I read the official jquery template docs but could not find anything on this. I tried something like {{ v

Answer 1

I do:

${xxx=13, ""}

and then i can use xxx in a sub or in the same template

Answer 2

I don't think that doing the $item approach is too bad. It is consistent with where you would look for variables that are passed in via the options parameter to $.tmpl.

Another approach that I have used, based on a small tip here, is to actually define a "var" template tag.

Just do:

$.extend($.tmpl.tag, {
    "var": {
        open: "var $1;"
    }
});

Then you can use it in your templates like:

{{var xxx=123}}
...
<div>${xxx}</div>

Also, nice blog post here on custom jquery template tags: http://blog.sterkwebwerk.nl/2010/12/15/custom-jquery-template-tags-1/

Answer 3

You can extend jquery template with eval tag

$.extend($.tmpl.tag, { "eval": { open: "$1;"} });

and use

{{eval var xxx = 123}}
{{eval xxx += 23}}
