- Description
This function displays a message to the user, either at the top of page or in a dialog, depending on the context, using the Java API.
- The basic version of the function displays a message string.
- With additional options, a localized version of a message can displayed.
- Considerations
-
- The function displays the message in the UI, irrespective of any database insertions or updates (in other words, without interrupting the program flow).
- If the function is called multiple times, the messages are concatenated, and displayed together when the code returns to the platform. (Only one dialog is ever displayed.)
- The text is displayed in HTML format, so linebreaks (<br>) and text formatting (<b>, <i>) can be included.
- In a JSP page, this function does nothing. Use a JavaScript alert(), instead.
- Syntax
- <syntaxhighlight lang="java" enclose="div">
void Functions.showMessage(String message); void Functions.showMessage(String key, String[] args); </syntaxhighlight>
To display a localized message:
Element Type Description key String A category name, followed by '.' and a message or label identifier (a "token").
Example: #categoryname.tokennameargs Array of String Optional. Causes the first parameter to be treated as a key. - If no additional arguments are passed, the original key (the message string) is displayed.
- If arguments are passed, the key is used to retrieve a Custom Label in the current language, with the supplied arguments injected into it.
To provide a key for a label that has no arguments (for example, for a label in the #custom category), use:
- <syntaxhighlight lang="java" enclose="div">
Functions.showMessage("#custom.label", null) </syntaxhighlight>
To include linebreaks in the message, specify <br>:
- <syntaxhighlight lang="java" enclose="div">
Functions.showMessage("Include
for
newline");
</syntaxhighlight>
- Return
-
- Returns the localized message configured on the key in the Translation Workbench.
- If no key is configured in the translation workbench, then the passed key is returned.
