Jquery Live and Proxy with context

I'd like to set a context for a function in order to limit its execution to only its inside elements.

$('#btn').live('click',function(){
    $.proxy(test(),$(this).closest('div'));
});

function test(){
     //doSomething
}

but the context in test() function is not the closest DIV containig my #btn button but the entire page. Could you help me开发者_如何学Python ?

$.proxy returns a function.

var mytest = function(){
// do something with `this` bound to the jquery collection to be 
// created in the future sometime 
}
$('#btn').live('click',function(){
  // reassign mytest to a new function proxying the context through 
  // a relative jquery collection
  mytest = $.proxy(mytest,$(this).closest('div'));
});

This is kind of weird and clumsy, but it should do what you're thinking. There a good chance of running into async issues because the proxy happens on the click. Without knowing the specifics of your problem I don't know if using proxy is what you need.

Changing test() to test doesn't seem to make a difference, strange how that's not working -- but after reading the comments on the jQuery page for .proxy -- it seems it's plagued with problems and inconsistencies. I would use something along these lines:

HTML

<div>hello</div>

jQuery

function test()
{
  alert($(this).html()); // Will alert hello
}

$(document).ready(function() {
    test.call($('div').get(0)); // I use .get() so only the DOM object is passed.
                                // That makes it more consistent with how jQuery 
                               // passes objects to .each, etc.
})
