Question

How to declare variables this way:

var sarr = $("#crop_vals").find("input");
$(sarr).each(function() { 
    var $(this).attr("id") = $(this).val();
});

What I want is to have var named the id equivalent to the value.

To set the “variables” globally (though you shouldn’t do this because it’s asking for trouble)

var sarr = $("#crop_vals").find("input");
$(sarr).each(function() { 
    window[ this.id ] = this.value;
});

To set them in a safer way, you could do

var sarr = $("#crop_vals").find("input"),
    myVars = {};
$(sarr).each(function() { 
    myVars[ this.id ] = this.value;
});

and access with myVars[ id ].
