setTabTextStyle()

| Name | Type | Description |
|---|---|---|
style | string | A CSS specification string used to set a tab’s text style. If null or undefined, the tab’s default text style is used. |
tabId | string | The ID of the tab on which to set the text style. If null or undefined, the enclosing tab’s ID is used. |
callback | function | JavaScript method that’s called upon completion of the method. |
This method is asynchronous, so it returns its response in an object in a callback method. The response object contains the following field:
| Name | Type | Description |
|---|---|---|
success | boolean | true if setting the tab’s text style was successful, false if setting the tab’s text style wasn’t successful. |
If this method is called without passing in a tab ID, the tab in which the Visualforce page is enclosed is used. If there isn’t an enclosing tab, the error message Cannot get a workspace or view tab from the given ID displays in the browser’s developer console.
