How To Know That Primefaces Selectbooleancheckbox Is Selected Or Not Using Javascript?

I want to get p:selectBooleanCheckbox component and check if it is selected or not using javascript

Solution 1:

You can define the widgetVar of your selectBooleanCheckbox

<p:selectBooleanCheckbox id="check" widgetVar="myCheckbox" value="#{myBacking.value}"/>

You can access in js the Primefaces object in these ways

directly with myCheckbox
PF("myCheckbox")
window["myCheckbox"]
PrimeFaces.widgets["myCheckbox"]

So, to get the checkbox state you can use

myCheckbox.input.is(':checked')
PF("myCheckbox").input.is(':checked')
window["myCheckbox"].input.is(':checked')
PrimeFaces.widgets["myCheckbox"].input.is(':checked')
