django template blocks and jquery

[Joel Stransky]

Still very new to django so excuse the newbish questions.

This might be obvious but I need a smart solution.

I have a template that runs a jquery function at document ready which
defines a few other functions. I only need a couple of these functions in
the template I'm extending, the other I need tacked on to specific children
of the template.

So I have:

<script type="text/javascript">
$(document).ready(function(){
//function 1
$("#my_id").click(function() { /* do stuff */ });

//function 2
$("a.someClass").click(function() { /* do stuff */ });

//function 3
$("#my_other_id").hover(function() { /* do stuff */ });
});
</script>

But what I need is to able to insert function 3 (or others) in a child of my
base template
Ideally it would look like this:

{% block jquery %}
{{ block.super }}
//function 3
$("#my_other_id").hover(function() { /* do stuff */ });
{% endblock jquery %}

How do I achieve something to that effect?

There are a couple of ways, but here's one off the top of my head:

Base template:
<script>
$(function(){
function1() { ... }
function2() { ... }
{% block additional_domready %}{% endblock %}
});
{% block additional_js }%}{% endblock %}
</script>

child template that extends base template:

{% block additional_domready %}
function3() { ... }
{% endblock %}

{% block additional_js %}
//js that runs outside of document.ready
{% endblock %}

That was my first thought too David but the %} both closes the js method
declaration and causes a syntax error.
Turns out however that you can have more than 1 domready function so I just
enclosed the global ones in a new .js file and appended a completely new
$(document).ready() function in the child.

It shouldn't - unless you try to display the unrendered template in
your browser, of course.

Ok thanks. I never actually tried it, just assumed it wouldn't work. I'll
give it a shot next time I run into this.

FWIW, your current solution is IMHO way cleaner (=> more readable,
more explicit, and less likely to break if / when something changes in
your base template), so I strongly suggest you stick to it.

My 2 cents...
