问题 I know that S2 provides a clean way to fetch the request parameters in you action class all you need to follow these simple rules. Create a property with same name as request parameter name. Create getter and setters for this property or make property public (for S2.1+) However, when I do this in an AJAX call like this: $.ajax({ url: '/gma/getJSONData.action?tspName='+tspName+'&thresholdType='+thresholdType, I don't get the tspName parameter inside action class.

问题 I need to hide a field on page load based on the value of a request attribute. I don't want a 'hidden' field because I want to show it again. I don't want to do this with javascript. How is this done with jsp tags? 回答1: Set a condition where display is block if the condition is true. Else if the condition is false set the display to none. <c:set var="inputDisplay" value="1" /> <!-- This same as your request attribute --> <c:choose> <c:when test="${inputDisplay == 1}"> <input type="text" /> <
