将参数传递给a4j:function

Question

我如何从javascript传递参数到a4j:jsFunction,我想调用categoryChanged和我放在那里的任何东西 - 甚至显式的String,参数在bean端是不可见的.

这是js代码:

$(function() {
    $( "#resizable" ).resizable();
    $( "#selectable" ).selectable({stop: function(event, ui) { 
        $( ".ui-selected", this ).each(function() {
            var index = $( "#selectable li" ).index( this );
            categoryChanged("Test String");
            categoryChanged(this);
            categoryChanged(ui.id);
            categoryChanged($( "#selectable li" ).value(this));
        });
        // ajax call to render the content
    }});
    $("#menu").buttonset();

});

和a4j函数定义:

<a4j:jsFunction name="categoryChanged"
        action="#{appexplorerbean.categoryChanged}" limitToList="true"
        oncomplete="" reRender="appexplrtable">         
<a4j:actionparam name="newCategory" />
</a4j:jsFunction>

您需要指定要设置的参数.

<a4j:jsFunction name="categoryChanged"
        action="#{appexplorerbean.categoryChanged(newCategory)}" limitToList="true"
        oncomplete="" reRender="appexplrtable">         
    <a4j:actionparam name="newCategory" assignTo="#{newCategory} />
</a4j:jsFunction>

或直接设置值.

<a4j:jsFunction name="categoryChanged"
            action="#{appexplorerbean.categoryChanged}" limitToList="true"
            oncomplete="" reRender="appexplrtable">        
    <a4j:actionparam name="newCategory" assignTo="#{appexplorerbean.newCategory} />
</a4j:jsFunction>

希望它仍然有帮助
