Parsing html description field in incident

[Richard Thomas2]

Hi,

I'm trying to create a before business rule that changes the short description of an incident to something from the description of the incident. I'm trying to parse the description (never done this before!).

Basically - I want to take all the text after Alert Description: in the description and populate the short description with it. I have this script;

current.short_description = u_description_html.indexOf("Alert Description:==14")

Will this work? Be kind - I've new to coding!!

Thank you

Rich

if you want to do it code-wise, this would do it:

var descSplit = current.description.split('Alert Description:');

current.short_description = descSplit[1];

Thank you - that works perfectly.

Final question is it possible to limit the characters that I'm bring over from the description...? I probably only need to use the first 15 characters.

Thanks for your help

Hi Richard,

If you only need to 15 first, you can use substring function to pull that out. 

var descSplit = current.description.split('Alert Description:');
current.short_description = descSplit[1].substring(0,14);

Ah ok - thank you Goran - I will try this in the morning. Will that take all of the text after ‘Alert Description’? Regards Rich
