Java-script object - get variable name
To begin with, I'm not even sure, if it is the ri开发者_如何学Goght way to do it.
Let's say, i have script (jquery included) like this:
foo = function() {
this.bar = function() {
alert('I\'m bar');
}
this.test = function() {
$('body').append('<a onclick="my_var.bar();">Click me</a>');
}
this.test();
}
var my_var = new foo();
Is there any way, i could make variable "my_var" dynamic inside function "foo". So I could do something like
$('body').append('<a onclick="'+the_variable_which_im_assigned_to+'.bar();">Click me</a>');
Thank you
//Edit:
I'm sorry if i wasn't clear enough, because I'm not quite sure of what I'm trying to do myself.
My goal is to replace line
$('body').append('<a onclick="my_var.bar();">Click me</a>');
with
$('body').append('<a onclick="'+what_ever_should_go_here+'.bar();">Click me</a>');
So when i call
var my_var = new foo();
var your_var = new foo();
var our_var = new foo();
I would be able to call functions inside each object (after they append something into document body).
You should use anonymous handler functions instead of inline events, like this:
$('<a href="#">Click Me</a>')
.click(function() { my_var.bar(); return false; })
.appendTo('body');
In addition to switching from the inline event handler, you'll need to use a closure to access the Foo instance within the handler.
function Foo() {
var self = this;
this.test = function() {
$('body').append(
$('<button>something</button>').click(function () {
self.bar(); return false;
}));
}
}
If that's the general plan you want/need to use to attach event handler, yeah, send in the name of the variable to the function that foo
refers to:
foo = function(name_of_the_variable_which_im_assigned_to) { [...] };
