Execute Javascript based on the selected checkbox status

I am currently trying to determine the appropriate timing for invoking a JavaScript function when a checkbox is set to true. The challenge lies in the fact that the checkbox has a dynamically generated name as it is part of a table populated from a database. Each checkbox is uniquely named based on the sequence number and a given name. Upon completion, the checkbox triggers an Ajax call to invoke a JavaScript function through a bean listener. I am using the JSF 2 datatable in this particular scenario.

Is there a way to validate whether the rowCheckbox is checked before triggering the JavaScript function (as indicated by the oncomplete ajax parameter)?

    ---
    <h:selectBooleanCheckbox id="rowCheckbox">
                                <a4j:ajax event="valueChange" listener="#dashboardController.tableRowIndexEvent}" execute="@form" oncomplete="addMarker('${item.geoposition.latDecDeg}', '${item.geoposition.longDecDeg}', '${item.geoposition.locationName}')"/>
        </h:selectBooleanCheckbox>
     ----

Best regards, Chris

Answer №1

Here is a simple way to verify if a checkbox is checked:

<input type="checkbox" id="cb1" onclick="if(this.checked) alert('Yay!'); else return false;" />

Check out the demonstration here: http://jsfiddle.net/yKEWF/3/

Answer №2

Although I haven't had experience with JSF, it is possible that the listener is confined to the checkbox itself.

In that case, the correct syntax would be "this.checked"
