LoopOptions

You can review the details of the LoopOptions JSP tag.

Description

The loopOptions JSP tag builds the options belonging to the HTML select tag.

Attributes

binding - Required. Binding string that points to the repeating element in the API output. The repeating element must be one fixed with the at character (" @ ").

name - Optional. Attribute name within the binding element to be used for the description visible to the user in the option tag. If not passed, defaults to name, which means that searches for an attribute called name.

value - Optional. Attribute name within the binding element to be used for the value attribute of the option tag. If not passed, it defaults to value, which means that the application searches for an attribute called value.

selected - Optional. Binding string that must be evaluated and set as the default selected value. This is matched with the value attribute, not the description attribute. Defaults to blanks, for example, space (" ").

isLocalized - Optional. If passed as "Y" it obtains the localized description to be displayed based on the user's locale from the YFS_LOCALIZED_STRINGS table.

targetBinding - Optional. If the target binding of the select is different than the source binding, you must specify the target binding as input when using loopOptions. This ensures that data entered by the end user is not be lost even when an exception is generated in the API.

Body

None.

Examples

This example shows how query types (is, starts with, contains) are shown in a select tag from the output of an API.

<td nowrap="true" class="searchcriteriacell" >
   <select name="xml:/Item/@ItemIDQryType" class="combobox" >
      <yfc:loopOptions 
binding="xml:/QueryTypeList/StringQueryTypes/@QueryType" 
name="QueryTypeDesc" value="QueryType" selected="xml:/Item/@ItemIDQryType"/>
   </select>
   <input type="text" class="unprotectedinput" 
<%=getTextOptions("xml:/Item/@ItemID") %> />
</td>

This example uses combo boxes within an editable list:

An underscore character (" _ ") and a counter must be appended to the name attribute of the select element.
The name of the counter is the value of the ID attribute specified in the loopXML tag. The ID attribute should always be set to the same as the child node name on which you are looping.

<select name="xml:/Order/Instructions/Instruction_
<%=InstructionCounter%>/@InstructionType" class="combobox"> 
   <yfc:loopOptions binding="xml:InstructionTypeList:/CommonCodeList/
@CommonCode" name="CodeShortDescription" value="CodeValue"
selected="xml:/Instruction/@InstructionType"/> 
</select>
