Session value range: </P> <p> <s: property value = "# session. mysessionpropkey "/> <br/> <s: property value =" # session ['mysessionpropkey'] "/> </P> <p> value range of request: </P> <p> <s: property value = "# request ['myrequestpropkey']"/>Page:

Session range value:

<S: property value = "# session. mysessionpropkey"/>
<S: property value = "# session ['mysessionpropkey']"/>

Value range:

<S: property value = "# reques ['myrequestpropkey']"/>

In the session, it is easy to use % {# variable. attribute name}, but the value in the request is more complex.

 

<S: textfield value = "request ['myrequestpropkey']"/> in this way, no numerical value is obtained.

 

Solution:

Session value: </P> <p> <s: label Label = "edit user" value = "% {# session. user. m_susername} "required =" true "/> </P> <p> request value: </P> <p> <s: textfield name = "bdef" value = "% {# request. object Name. property name} "size =" 50 "maxlength =" 50 "/>
