firefox - Javascript, aliases and IE -

-

In an attempt to save space, I have created a complete group of all aliases for the function in my code. It works fine in FF, but now I'm trying to add support for IE and it's not happy. 

  j = string; F0 = j.fromCharCode; J = j.prototype; J.f1 = j.indexOf; J.f2 = j.lastIndexOf; J.f3 = j.concat; J.f4 = j.substring; Function aka (c, e) {return function () {return c [e] .apply (c, logic);}}} w = window.location; D = document; B = document.body; F5 = aka (d, "createElement"); F6 = aka (b, "appendChild"); F7 = aka (d, "getElementById"); ... etc.

I know that the alias () function does not work in IE is an alternative method that works in both browsers?

This is one of those answers that does not answer directly to your question, but I think That it will help you:

You should write your code without all the small variables and surnames. Write it completely because it will be very easy to maintain

then , when you move the code into production, keep your code through a miner which Aliyasing and small variables for you.

You can try to do any of these two for you (there are many good people too):

  2. (Turn on 'shrub variables')

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
