==Description==

The JavaScriptRetriever element allows you to define a helper to use into the XSL transformations.

We define the functions that run JavaScript code and return the last assignment/function result.

The script to be executed can contain metadata resolved at runtime.

=={{GVESB}} configuration==

JavaScriptRetriever element is used by [[Retriever_Config|RetrieverConfig]].

The following table shows its attributes:
{|class="gvtable"
! Attribute !! Type !! Description
|-
| type || fixed || retriever (unmodifiable)
|-
| class || fixed || it.greenvulcano.gvesb.datahandling.utils.JavaScriptRetriever
|}

Might contain the sub-elements:
* [[Description]]
* [[DataRetriever]]

===An example===

Define the following JavaScriptRetriever:
<syntaxhighlight lang="XML">
<JavaScriptRetriever class="it.greenvulcano.gvesb.datahandling.utils.JavaScriptRetriever" type="retriever">
<DataRetriever method="getElementMapping" signature="ELEMENT">
var mapping = {"Cognome":"1", "Nome":"2", "Indirizzo":"3", "Cap":"4", "Citta":"5", "Provincia":"6", "Nazione":"7",
"Telefono":"8", "EMail":"9"};
var res = mapping["@{{ELEMENT}}"];
if (res === undefined) {
res = "-1";
} else {
res;
}
</DataRetriever>
<DataRetriever method="mustBeUpperCase" signature="ELEMENT">
var mapping = {"Cognome":"true", "Nome":"true", "Indirizzo":"true", "Citta":"true", "Provincia":"true"};
var res = mapping["@{{ELEMENT}}"];
if (res === undefined) {
res = "false";
} else {
res;
}
</DataRetriever>
</JavaScriptRetriever>
</syntaxhighlight>

to be applied to the transformation:
<syntaxhighlight lang="XML">
<xsl:variable name="element" select="local-name(.)"/>
<xsl:variable name="mapping" select="java:it.greenvulcano.gvesb.datahandling.utils.JavaScriptRetriever.getData('getElementMapping', $element)"/>
<xsl:variable name="uppercase" select="java:it.greenvulcano.gvesb.datahandling.utils.JavaScriptRetriever.getData('mustBeUpperCase', $element)"/>
</syntaxhighlight>
