<#-- * spring.ftl * * This file consists of a collection of FreeMarker macros aimed at easing * some of the common requirements of web applications - in particular * handling of forms. * * Spring's FreeMarker support will automatically make this file and therefore * all macros within it available to any application using Spring's * FreeMarkerConfigurer. * * To take advantage of these macros, the "exposeSpringMacroHelpers" property * of the FreeMarker class needs to be set to "true". This will expose a * RequestContext under the name "springMacroRequestContext", as needed by * the macros in this library. * * @author Darren Davison * @author Juergen Hoeller * @since 1.1 --><#-- * message * * Macro to translate a message code into a message. --><#macro message code>${springMacroRequestContext.getMessage(code)}</#macro><#-- * messageText * * Macro to translate a message code into a message, * using the given default text if no message found. --><#macro messageText code, text>${springMacroRequestContext.getMessage(code, text)}</#macro><#-- * url * * Takes a relative URL and makes it absolute from the server root by * adding the context root for the web application. --><#macro url relativeUrl>${springMacroRequestContext.getContextPath()}${relativeUrl}</#macro><#-- * bind * * Exposes a BindStatus object for the given bind path, which can be * a bean (e.g. "person") to get global errors, or a bean property * (e.g. "person.name") to get field errors. Can be called multiple times * within a form to bind to multiple command objects and/or field names. * * This macro will participate in the default HTML escape setting for the given * RequestContext. This can be customized by calling "setDefaultHtmlEscape" * on the "springMacroRequestContext" context variable, or via the * "defaultHtmlEscape" context-param in web.xml (same as for the JSP bind tag). * Also regards a "htmlEscape" variable in the namespace of this library. * * Producing no output, the following context variable will be available * each time this macro is referenced (assuming you import this library in * your templates with the namespace 'spring'): * * spring.status : a BindStatus instance holding the command object name, * expression, value, and error messages and codes for the path supplied * * @param path : the path (string value) of the value required to bind to. * Spring defaults to a command name of "command" but this can be overridden * by user config. --><#macro bind path> <#if htmlEscape?exists> <#assign status = springMacroRequestContext.getBindStatus(path, htmlEscape)> <#else> <#assign status = springMacroRequestContext.getBindStatus(path)> </#if> <#-- assign a temporary value, forcing a string representation for any kind of variable.
