enterInFieldenterInField
HyperCard sends the enterInField command to a field when the user presses Enter and the insertion point is in the field. This command saves the results of any changes the user or a handler makes to a field and closes the field. HyperCard sends a closeField message if the user made changes to the text or sends exitField if the user did not make any changes). You can handle the enterInField message as follows: on enterInField statements end enterInField
ExamplesNote the difference between these two scripts: on addText select after text of bkgnd field "Example" -- set the insert point type "Hello world" -- add some new text enterKey end addText on addText select after text of bkgnd field "Example" -- set the insert point type "Hello world" -- add some new text enterInField end addText If you type addText into the Message box and press Return, the first script continually adds "Hello world" after existing text in the field. This is because the enterKey command sends the contents of the Message box—which in this case is addText—to the current card. With the second script, addText places "Hello world" into the field once and then closes the field, saving the addition.
