INDD: Check if LayerName contains specific Char

[schlindibus]

Hello guys

I was wondering how to check if a specific char is contained in the layer name.
Tried .contains("_") and .include("_") but neither worked...

Does anyone know the Answer to this question?

Thanks a lot

Hey, try with indexOf:

'My_Layer'.indexOf('_') > -1; // returns true
'MyLayer'.indexOf('_') > -1; // returns false

@GNDGN  You're the Man 🙂

I forgott about .indexOf... ups

Thanks for your extremely fast reply!

Or may be you can try match:

'My_Layer'.match('_') != null

.match() uses a regular expression (even if your example contains a literal), and creates an array -- which is expensive. If you have to use a regular expression to test whether a string contains a substring, .test() is quicker because it doesn't create an array, it returns a boolean.

Thank you for explaining, .test() is also new for me.
