[jQuery] Re: Plugin developement
Another "solution" i found on a Blog.
Instead of adding a function to the Plugin, create a seperate object
within the scope of the plugin.
;(function($)
{
$.fn.pluginname = function(options)
{
// private method
function _doSomethingPrivate()
{
}
// public method
$.fn.pluginname_doSomethingPublic = function()
{
_doSomethingPrivate();
return this;
}
};
Like that you still could write something like
$
('#example').pluginname().pluginname_doSomethingPublic().otherJquery();
Of course there are still some limits to it. ie not declared before $
().pluginname().
So from this point of view the way jmap is handling it is indeed
somehow better.
Its just, i like the way of having seperate methods instead of having
one multipurpose method.
But i guess i will go the way jmap does it, i still can seperate the
"comands" into private methods.
Its just u can't realy seperate anymore into private or plubic
methods.

[jQuery] Re: Plugin developement
Hi,
Wow, thanks to both of you. Wouldn't have thought about such an
construct. Maybe because i'm not that familiar with javascript at all.
Somehow i thought you can't access an object while creating it.
But also the way Balazs was mentioning about jmap looks interesting. I
will have a closer look into it soon.
For now i will try out the way mentioned above.
The only thing i don't like in this solution is, that after calling
the method u can't add another right after like :
$('#example').pluginname.doSomethingPublic().doSomethingElse();
is there a solution to it, except the way jmap does.

Is there realy nobody out there, who can point me into the right direction? A link to a tutorial would be already great. If somebody doesn't understand the question, please tell me, i will try to explain it further.
[jQuery] Plugin developement
Hi @ all,
i have a problem with the understanding of public methods of an
plugin. Specialy how to create and link them to the plugin.
For example:
;(function($)
{
$.fn.pluginname = function(options)
{
var _options = $.extend(
{
label: "data",
debug : false
}, options || {});
return this.each(function()
{
// this works, of course
_doSomethingPrivate();
// this too
var data = _options.label;
});
// private method
function _doSomethingPrivate()
{
}
};
// public method
$.fn.pluginname.doSomethingPublic = function()
{
// this won't work
_doSomethingPrivate();
// this is not accessible either
var data = _options.label;
}
})(jQuery);
Obviously the above code won't work. I've tried several things to get
this working, but had no success.
So please, can somebody explain me this or point me into the right
direction.
If this question was aked before (and i'm somehow sure of this, but
had not found something jet) please let me know the Url.
Sorry for my english, i'm not a native speaker of this language.

Does really nobody got an Idea? Greets Martin
[jQuery] $.get and $.getJSON
Hi,
i encounter problems with the getJSON method
when i do that:
$.getJSON("http://localhost/jas/www/rmt.php5?action=airport_state";,
{country: $(this).val()}, function(json)
{
$.log(json);
});
nothing happends. there is even no connection trace in firebug
but
$.get("http://localhost/jas/www/rmt.php5?action=airport_state";,
{country: $(this).val()}, function(json)
{
eval("var a = "+json);
$.log(a);
});
works fine
php sends header("Content-type: application/json");
so thats fine to.
jquery version is 1.2.2
Any suggestions?
Martin
