how to use object inside another objects function

I have an object 'params' and another object 'options' whith function assigned 开发者_运维问答to its parameter. And I want to use 'params' element inside 'options' function. How can I do that?

 var params = {
     'errorId': 'dd.error',
 }  $(function() {
var options = {
    'success': function() { alert(params['errorId']; }
});

Try removing var keyword from params to make it available later/globally:

 params = {
     'errorId': 'dd.error',
 }  $(function() {
var options = {
    'success': function() { alert(params['errorId']; }

});

Hm. It looks like you're missing a curly brace after options. What doesn't work? Do you get a syntax error? The code there, other than the missing curly, looks like it should work just fine.

There's some errors in your posted code.

It should look more like this: Live example

var params = {
    'errorId': 'dd.error',
};

$(function() {
    var options = {
        'success': function() {
            alert(params['errorId']); // <--- added missing ')'
        }
    }; // <-- added missing '}' to options var

    options.success(); // <--- added by me to execute function
});
