GetParameter

You can review the details about the getParameter JSP function.

Description

This JSP function obtains the value of the parameter requested from the pageContext() function and requests in the following order:

pageContext.getAttribute() -> If not found -> request.getAttribute() -> If not found -> request.getParameter()

This function is typically used to extract the parameters specified while using various Presentation Framework JSP tags such as yfc:makeXMLKey and yfc:loopXML.

Syntax

String getParameter(String paramName);

Input parameters

paramName - Required. Name of the parameter whose value is required.

Example

This example shows how an order list view shows a hyperlinked order number that opens the default detail view. The yfc:makeXMLInput JSP tag uses the keys specified to prepare and stores the XML. The XML can be extracted using the getParameter() function.

<table class="table" editable="false" width="100%" cellspacing="0">
 <thead> 
    <tr>
      <td sortable="no" class="checkboxheader">
          <input type="checkbox" name="checkbox" value="checkbox" 
onclick="doCheckAll(this);"/>
      </td>
      <td class="tablecolumnheader"><yfc:i18n>Order_#</yfc:i18n></td>
      <td class="tablecolumnheader"><yfc:i18n>Enterprise</yfc:i18n></td>
