Question

why can’t i have a variable in an object? I get an error like:

"Uncaught SyntaxError: Unexpected token this"

My code is like this.

$("#search_options input:checkbox").on('click', function() {
  var params = { 
    $(this).attr('name') : $(this).val(),
  };
  var str = jQuery.param(params);
});

I’m sure that $(this) is working because I tried to console.log it outside the params object then i is working.

Object literals cannot have variable property names. You’ll have to assign the property like so:

...
var params = {};
params[$(this).attr('name')] = $(this).val();
var str = jQuery.param(params);
