#** * spring.vm * * This file consists of a collection of Velocity macros aimed at easing * some of the common requirements of web applications - in particular * handling of forms. * * Spring's Velocity support will automatically make this file and therefore * all macros within it available to any application using Spring's * VelocityConfigurer. * * To take advantage of these macros, the "exposeSpringMacroHelpers" property * of the VelocityView 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 *# #** * springMessage * * Macro to translate a message code into a message. *##macro( springMessage $code )$springMacroRequestContext.getMessage($code)#end#** * springMessageText * * Macro to translate a message code into a message, * using the given default text if no message found. *##macro( springMessageText $code $text )$springMacroRequestContext.getMessage($code, $text)#end#** * springUrl * * Takes a relative URL and makes it absolute from the server root by * adding the context root for the web application. *##macro( springUrl $relativeUrl )$springMacroRequestContext.getContextPath()${relativeUrl}#end#** * springBind * * 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 "springHtmlEscape" variable in the template context. * * Producing no output, the following context variable will be available * each time this macro is referenced: * * $status : a BindStatus instance holding the command object name, * expression, value, and error codes and messages 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( springBind $path ) #if("$!springHtmlEscape" != "") #set( $status = $springMacroRequestContext.getBindStatus($path, $springHtmlEscape) ) #else #set( $status = $springMacroRequestContext.getBindStatus($path) ) #end#end#** * springBindEscaped * * Similar to springBind, but takes an explicit HTML escape flag rather * than relying on the default HTML escape setting. *##macro( springBindEscaped $path $htmlEscape ) #set( $status = $springMacroRequestContext.getBindStatus($path, $htmlEscape) )#end#** * springFormInput * * Display a form input field of type 'text' and bind it to an attribute * of a command or bean. * * @param path the name of the field to bind to * @param attributes any additional attributes for the element (such as class * or CSS styles or size * *##macro( springFormInput $path $attributes ) #springBind($path) <input type="text" name="${status.expression}" value="$!status.value" ${attributes}#springCloseTag()#end#** * springFormPasswordInput * * Display a form input field of type 'password' and bind it to an attribute * of a command or bean.
