• Optional:
  • id: document-unique id for the tag.
  • valueVar: the scripting-variable name to which each value of a collection or property will be bound. Default id + "Value", or "cValue" if no id was specified.

Nothing.

• forEachInList: Evaluates its body for each member of an indexed collection.
  • Required attributes:
    • collection: the java.util.List over which the tag will iterate. This should be a JSP expression or an EL value expression.
  • Optional attributes:
    • from: the first index for which to evaluate the tag's body. Default 0.
    • to: the last index for which to evaluate the tag's body. Default collection.size() - 1.
    • step: the quantity by which the index should be incremented for each iteration. Default 1.
    • indexVar: the scripting-variable name to which the current index will be bound. Default id + "Index", or "cIndex" if no id was specified.
  • Scripting variables:
    • cIndex: the current index into the collection. Nested scope.
    • cValue: the value in the collection at the current index. Nested scope.
• forEachIndexedProperty: Evaluates its body for each value of an indexed property on a Java Bean.
  • Required attributes:
    • name: the name of the bean variable, as declared in a prior scriptlet or <jsp:useBean id="name">.
    • property: the name of the indexed property to access.
  • Optional attributes:
    • from: the first index for which to evaluate the tag's body. Default 0.
    • to: the last index for which to evaluate the tag's body. Default n, where n is the last index of the property.
    • step: the quantity by which the index should be incremented for each iteration. Default 1.
    • indexVar: the scripting-variable name to which the current index will be bound. Default id + "Index", or "cIndex" if no id was specified.
  • Scripting variables:
    • cIndex: the current index into the property. Nested scope.
    • cValue: the value of the property at the current index. Nested scope.
• forEachInMap: Evaluates its body for each key-value pair in a Map.
  • Required attributes:
    • collection: the java.util.Map over which the tag will iterate. This should be a JSP expression or an EL value expression.
  • Optional attributes:
    • keyVar: the scripting-variable name to which the current key will be bound. Default id + "Key", or "cKey" if no id was specified.
  • Scripting variables:
    • cKey: the current key on the map. Nested scope.
    • cValue: the value in the map for the current key. Nested scope.
• forEachMappedProperty: Evaluates its body for each key-value pair of a mapped property on a Java Bean. Mapped properties are not strictly part of the Java Beans Framework, but they're an extremely common extension.
  • Required attributes:
    • name: the name of the bean variable, as declared in a prior scriptlet or <jsp:useBean id="name">.
    • property: the name of the mapped property to access.
  • Optional attributes:
    • keyVar: the scripting-variable name to which the current key will be bound. Default id + "Key", or "cKey" if no id was specified.
  • Scripting variables:
    • cKey: the current key on the property. Nested scope.
    • cValue: the value of the property for the current key. Nested scope.
