How to check part of a string

[gunishi]

Hi there, 

This is more of a basic question, but I would like to check the value in the string for a certain combination of letters, let's say 'ABC'.

How would I return true if the field contains ABC-234, and I am only checking to see if it contains ABC.

I know I could do this via a filter, but in script, how would be best to do this? Just via an encoded query?

Many thanks!

Hi @gunishi ,

In script, you can check if a string contains a specific substring using the indexOf() method or a regular expression. Here's how you can do it:

1. Using indexOf(): You can use the indexOf() method to check if a string contains a specific substring. If the method returns a value greater than or equal to 0, it means the substring is present in the string.

   var str = 'ABC-234';
   var substring = 'ABC';
   
   if (str.indexOf(substring) !== -1) {
       // Substring found in the string
       gs.info('Substring found');
   } else {
       // Substring not found in the string
       gs.info('Substring not found');
   }
   

2. Using Regular Expression: You can also use a regular expression to achieve the same result. Regular

   var str = 'ABC-234';
   var regex = /ABC/;
   
   if (regex.test(str)) {
       // Substring found in the string
       gs.info('Substring found');
   } else {
       // Substring not found in the string
       gs.info('Substring not found');
   }
   

   Both of these methods will return true if the substring 'ABC' is found in the string 'ABC-234', and false otherwise. Choose the method that best fits your requirements and coding style.

Hi @gunishi  

Below script can be used in BR. 

If(current.<stringfieldname>.indexOf('ABC')>=0){

gs.addInfoMessage('ABC Present');

}

And below script can be used in client script 

var stringfieldname = g_form.getValue('<stringfield>');

if(stringfieldname.indexOf('ABC')>=0){

alert('ABC PRESENT');

}

OR if you are trying to use it in GlideQuery then you can use below 

var grRec = new GlideRecord('tablename');

grRec.addEncodedQuery('stringfieldnameLIKEABC');

grRec.query();

Hi @gunishi 

Apart from what Ratnakar has suggested, you can also try using includes function:

var str = "abc123";
var textFound = str.includes("123");// this would return true
