Scripting Questions

[jesusemelendezm]

These days I have been learning how to use ServiceNow scripts. I was stuck- in couple of scripts one in a UI action and another one in an e-mail template. I received help from various users here which I really appreciated. While navigating the scripts, testing and so on, I've collected the following questions. Some of them are very basic and   I look to clarify/confirm with your help.

1)           How do you quickly differentiate between a block of client script and server script?

2)           Where can I use client side script and where I cannot?

3)           Where can I use server side scripts and where I cannot? Where can I use both?

4)           E-mail template script — if I am using tags <script> statement </script> this indicates that I am using client script. Between these tags, can I not use server scripting?

5)           How do you easily verify syntax on e-mail templates?

6)           When referring to referenced field values- you have to use Sys_ID?

7)           When referring to strings values in a field you can use quotes'' '' (e.g. short_description = 'desktop broken')?

😎           When referring to choice type fields — It is necessary to use the numeric value (e.g. state: cancelled — value: 7)?

9)           Where can I use HTML tags to change appearance of texts and numbers?

10)     You can build a query from lists and copy the query. Where do you use these queries? For example: (descriptionLIKEtex) when I look for a description that contains word letters tex. I meant, what's the usability of copying queries from a list- can these be used in a script? How?

11)     Where can I have a list of out-of-the-box functions that I can use? For example, function onCellEdit, onChange, onLoad, etc.

i will try answering your questions

1. if there is g_form, it is client side... if it has gs. , it is server side (this will hold good in most places)

2. client script -> client script, ui policy, ui action, catalog client script, catalog ui policy, ui script, ui macro,ui page, etc

3. server script -> script include, BR, scheduled job, ui action, etc

4. use <mail_script> for writing server side code

5. I do not think there is a way of doing this... But i use editor while using <mail_script>

6. But default it gives sys_id... but you can dot walk to access any other field too...

7. for string you can use both " or '

8. it is not neccessary to use string values

9. if it field, right click -> personalize style -> use your HTML....

10. you can right click and copy the queries and you can use 'addEncodedQuery' for gliderecords instead of individual addQuery on fields.

11. I am   not sure what you are referring here. But these are 3, that I am aware of that is available on client scripts...

Thanks for your help this clarifies a lot.

My last question was on functions, If I understand correctly... there are a number of out of the box functions that I can use ease coding additionally I can create my own JavaScript functions depending on what I wannna do.

Kalaiarasan,

Basically, in every area where I can use server script I also can use client script but where I can use client script I cannot use server script example "Catalog Client Script".
