How to make a call to controller method from button in Salesforce lightning?

Hi Portia,

If you want to call a server side controller method from lightning component then you have to create action in lightning component.Please refer below code-

Component-DemoComponent

<aura:component controller ="DemoApexCltr">
<lightning:button variant="brand" label="Submit" onclick="{!c.getAccountJS}" />
</aura:component>

Javascript Controller-

({
getAccountJS : function(component, event, helper) {
var action = component.get("c.getAllAccount");
action.setCallback(this,function(response){
console.log(':::'+JSON.stringify(response.getReturnValue()));
});
$A.enqueueAction(action);
}
})

Apex Controller - DemoApexCltr

public class DemoApexCltr {
@AuraEnabled
public static list<Account> getAllAccount(){
return [select id,name from account limit 10];
}
}
