如何知道是否使用JavaScript选择了primefaces selectBooleanCheckbox？

Question

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

<h:dataTable value="#{controller.list}" var="item">
    <h:column>
        <f:facet name="header">Ratio1</f:facet>
        <h:panelGrid columns="2">
            <p:inputText id="ratio1" readonly="#{true}" disabled="true" styleClass="ratio1"/>
            <h:outputText value="%" />
        </h:panelGrid>
        <p:selectBooleanCheckbox id="report1"  onchange="calculateTotalRatio()" value="#{controller.value}" valueChangeListener="#{fISHController.onCaseTestItemPatternReportFlagChange()}">    
        </p:selectBooleanCheckbox>          
    </h:column>

I want on calculateTotalRatio() function check if the checkbox is checked or not and depending on it update ratio1 input text with value

Answer 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')
