Important Update to Custom Scripting
The CustomScript Action now supports the LUA programming language. Visit our NEW Lua Scripting Resources!
- New accounts (created after October 29, 2018) will only have the option to use Lua in scripts.
- As of October 29, 2018 Custom Scripting Actions will default to Lua as the scripting type in the Custom Scripting Action for accounts created before this date. You will be able to switch to the Legacy Custom Scripting; though we highly encourage using Lua.
- In the long term, Legacy Custom Scripting Actions will be switched to read-only. The exact date on this is to be determined; we will send notifications well ahead of time.
This is the equivalent of the strlen function. This function returns the length of the string.
The below example will return the string length entered in the textbox from question ID 2.
Check it out in an Example Survey
%%string = sgapiGetValue(2); %%output .= 'String length;' .sgapiPrint_R(sgapiStrLen(%%string));
