Viewing Method Parameter Information

Parameter hints show the names of parameters in methods and functions:

In TypeScript, parameter hints are by default shown right in the editor making your code easier to read:

To view the parameter hints for a method

  • Place the caret anywhere within the call of the method or function and press Ctrl+P or choose View | Parameter Info on the main menu.

To configure the appearance and behavior of parameter hints

  1. In the Settings/Preferences dialog (Ctrl+Alt+S), choose General under Eitor, and then choose Code Completion. The Code Completion page opens.
  2. To have a complete method or function signature shown rather than a list of required types, select the Show full signatures checkbox in the Parameter info area. Make sure to include the required third-party libraries in the project source path. Otherwise, the names of parameters will not be displayed.
  3. To have the list of parameter types for the called method or function shown automatically after a certain delay, select the Auto pop-up (in ms) checkbox and specify the time period in milliseconds.
