| - | JavaScript can access variables by using the document.kmvar dictionary, see the Variables section. | + | ===== Using Keyboard Maestro Variables ===== |
| + | |||
| + | JavaScript can only **GET** Keyboard Maestro variables. They cannot be set: | ||
| + | |||
| + | ```javascript | ||
| + | var myData = document.kmvar.My_KM_Data | ||
| + | ``` | ||
| + | |||
| + | If your Keyboard Maestro Variable contains spaces, they must be replaced with underscores in the JavaScript, for example: | ||
| + | Keyboard Maestro Variable Name: My KM Data | ||
| + | JavaScript Reference: document.kmvar.My_KM_Data | ||
| + | |||
| + | ===== Saving Results to Keyboard Maestro Variables ===== | ||
| + | |||
| + | If you need to set a Keyboard Maestro Variable from the Browser JavaScript, then use a JavaScript return to return the data to the Keyboard Maestro Action, which can be set to save the results as a Keyboard Maestro Variable. | ||
| + | |||
| + | If you need to set more than one Keyboard Maestro Variable, one approach is to return the data for each variable on a separate line (or with delimiters of your choice), and then parse in a following Keyboard Maestro Search Action using RegEx. | ||
| + | |||
| + | ===== Examples ===== | ||
