How to avoid repeatedly click a button in a form?

Question

My code:

Answer 1

For the newer versions of PrimeFaces, the solution would be:

 <p:commandButton widgetVar="saveButton"
                 onclick="PF('saveButton').disable()"
                 value="save"
                 action="#{treeTableController.saveNewNodes}" 
                 oncomplete="PF('saveButton').enable();PF('Dlg').hide()"
                 update="productDataForm"/>

As a generic approach you could customize the button renderer.

I use this renderer for a PrimeFaces p:commandButton:

public class CommandButtonSingleClickRenderer extends CommandButtonRenderer {

    @Override
    protected void encodeMarkup(FacesContext context, CommandButton button) throws IOException {
        if (isEligible(button)) {
            String widgetVar = button.resolveWidgetVar(context);
            String onClick = getAttributeValue(context, button, "onclick");
            String onComplete = getAttributeValue(context, button, "oncomplete");
            button.setOnclick(prefix(onClick, getToggleJS(widgetVar, false)));
            button.setOncomplete(prefix(onComplete, getToggleJS(widgetVar, true)));
        }
        super.encodeMarkup(context, button);
    }

    protected boolean isEligible(final CommandButton button) {
        return button.isAjax()
               && button.isRendered()
               && button.getActionExpression() != null
               && !button.isDisabled()
               && !isConfirmation(button);
    }

    protected boolean isConfirmation(final CommandButton button) {
        String styleClass = button.getStyleClass();
        return styleClass != null && styleClass.contains("ui-confirmdialog");
    }

    protected String getToggleJS(final String widgetVar, final boolean enabled) {
        return String.format("var w=PF('%s');if(w){w.%sable();};", widgetVar, enabled ? "en" : "dis");
    }

    protected String getAttributeValue(final FacesContext context, final CommandButton button, final String attribute) {
        ValueExpression ve = button.getValueExpression(attribute);
        return ve == null ? null : (String) ve.getValue(context.getELContext());
    }

    protected String prefix(final String base, final String prefix) {
        return base == null ? prefix : prefix + base;
    }

}

faces-config.xml:

<render-kit>
  <renderer>
    <component-family>org.primefaces.component</component-family>
    <renderer-type>org.primefaces.component.CommandButtonRenderer</renderer-type>
    <renderer-class>com.whatever.CommandButtonSingleClickRenderer</renderer-class>
  </renderer>
</render-kit>

This renderer was added to PrimeFaces extensions 8.0. If you are using PFE, you can simply add this renderer to your faces-config.xml render-kit section:

<renderer>
  <component-family>org.primefaces.component</component-family>
  <renderer-type>org.primefaces.component.CommandButtonRenderer</renderer-type>
  <renderer-class>org.primefaces.extensions.renderer.CommandButtonSingleClickRenderer</renderer-class>
</renderer>

The <p:commandButton>'s Client Side API Widget:

• PrimeFaces.widget.CommandButton

• Method Params Return Type Description

• disable() - void Disables button
• enable() - void Enables button

So you can just use like this:

<p:commandButton widgetVar="saveButton"
                 onclick="saveButton.disable()"
                 value="save"
                 action="#{treeTableController.saveNewNodes}" 
                 oncomplete="saveButton.enable();Dlg.hide()"
                 update="productDataForm"/>

Use Javascript and Timer

<script>

function disableClick(){
   document.getElementById('saveButton').disables = true;
   setTimeout('document.getElementById(\'saveButton\').disables = false', 5000)"
}
</script>


 <h:form id="newBSTypePanel" >
    <h:panelGrid columns="2" id="newRecod" >
        <h:outputText value="Name"/><h:inputText value="#{treeTableController.newBStypeBean.currentObject.TYPENAME.value}" required="true" />
        <p:commandButton value="save" action="#{treeTableController.saveNewNodes}" oncomplete="Dlg.hide()" onclick="disableClick()" id="saveButton" update="productDataForm"/>
        <p:commandButton value="close" oncomplete="Dlg.hide()" />
    </h:panelGrid>
</h:form>
