ServiceNow Script Editor

All scripts, regardless of the script type, have two parts:

• Configuration: specifies when to execute the script logic
• Script: contains the script logic specifying what to do when the configuration criteria are met

Although the configuration is different for every script type, the Script Editor is the same for all scripts. The Script Editor features include:

• Real-time syntax checking

• Toolbar

• Syntax highlighting

• Scripting assistance

• Links to API documentation

  ​

  

Real-time Syntax Checking

The Script Editor indicates JavaScript syntax errors by placing warning (

Real-time syntax checking looks for errors in JavaScript syntax only. For example, the syntax checker finds missing semicolons at the end of lines, incomplete arguments in for loops, and missing characters such as ", ', [ and }. The syntax checker cannot find typos in variable names, functions, or method names. The syntax checker cannot determine if a script works as expected.
