[SalesForce] Can’t get data from lightning:radioGroup

I can't get value selected on lightning:radioGroup. It return undefined

<lightning:radioGroup aura:id="test"name="testName" options="{! v.options }" required="true" onchange="{! c.handleChangeButtonGroup }"/>

Controller

handleChangeButtonGroup:function(cmp, event, helper){
    var auraIdField = event.getSource().getLocalId();
    console.log(cmp.find(auraIdField).get("v.value"));
},

I don't want using event.getParam("value");, just using component get value it

Best Answer

Try this

Component:

<aura:component>
    <aura:attribute name="options" type="List" default="[
        {'label': 'Option1', 'value': '1'},
        {'label': 'Option2', 'value': '2'}
    ]"/>

    <aura:attribute name="radioGrpValue" type="String" />

    <lightning:radioGroup
        aura:id="radioGrp"
        name="radioButtonGroup"
        label="Choose Your Option"
        options="{! v.options }"
        value="{! v.radioGrpValue }"
        onchange="{! c.handleChange }"
    />
</aura:component>

Controller:

handleChange : function(component, event, helper) {
    var radioGrpValue = component.get("v.radioGrpValue");
    console.log('radioGrpValue',radioGrpValue);
}

[SalesForce] component.find(“Name”).get(“v.value”); is not working

create an aura:Attribute in your event, which you should pass while invoking the event

Aura attribute in event -

<aura:attribute name="sObjectId" type="Id" required="true" description="The Id of the selected SObject." />

While invoking event - var updateEvent = cmp.getEvent("eventName");

// Populate the event with the selected Object Id
updateEvent.setParams({
    "sObjectId" : value
});

In the event handler's action write following -

// Get the Id from the Event
var accountId = event.getParam("sObjectId");

Hope this helps :)

[SalesForce] Anyone figure out how to get selected tab in lightning:tabset using onselect event

selectedTabId is actually a two-way binding. You can determine which tab is selected by setting it to an attribute. Here's your example, modified:

.cmp

<aura:component description="myProblemComponent" implements="flexipage:availableForAllPageTypes">
    <aura:attribute name="selTabId" type="String" default="tab2" />
    <div aura:id="data-entry">
        <lightning:tabset onselect="{!c.tabSelected}" variant="default" selectedTabId="{!v.selTabId}">
            <lightning:tab aura:id="tab1" tabindex="1" id="tab1" title="Tab 1" label="Tab 1">

                FIRST TAB
            </lightning:tab>
            <lightning:tab aura:id="tab2" tabindex="2" id="tab2" title="Tab 2" label="Tab 2">
                Second tab
            </lightning:tab>
        </lightning:tabset>


    </div>
</aura:component>

Controller.js

({
    tabSelected: function(component,event,helper) {
        alert(component.get("v.selTabId"));
    }
})
