00:00:00,540 --> 00:00:07,320
As with CSX in JavaScript J query functions can be placed in an external JavaScript file and loaded

2
00:00:07,410 --> 00:00:10,560
in your existing document to do so.

3
00:00:10,700 --> 00:00:14,460
Create a new file for the purpose of this exercise.

4
00:00:14,600 --> 00:00:18,510
We'll save this file is JQ functions dot J.S.

5
00:00:34,230 --> 00:00:35,320
with your file saved.

6
00:00:35,370 --> 00:00:43,350
Enter your functions into the file and save the changes so go ahead and cut this function out

7
00:00:47,150 --> 00:00:54,290
and pasted into this into the JQ functions file and save the changes

8
00:00:58,830 --> 00:01:01,440
now in our main H team document.

9
00:01:01,800 --> 00:01:04,550
We simply need to call the script.

10
00:01:04,560 --> 00:01:09,350
We just created to do that you can type the following line of code

11
00:01:21,430 --> 00:01:22,000
and that's it.

12
00:01:22,000 --> 00:01:28,150
Now we can go ahead and save this save our main document and preview in our web browser just to make

13
00:01:28,150 --> 00:01:29,770
sure the function still work correctly.

14
00:01:36,090 --> 00:01:39,810
And it seems that everything is working so we know that the file was properly called.
