How to call a helper method from another helper method?

Hi,

Suppose I have 

a:funtion(component,event)
{
},
b:function(component,event,page)
{
}
And I wanted to call b() from a() 
where page is a Integer.
How can I do this?
I tried the one given below but it didn't work
a:funtion(component,event)
{
    this.b(component,event,1);
},
b:function(component,event,page)
{
}

Hi Soundharyaa,

I found this link that has a small implementation of a similar scenario can you please have a look at it once:

>> https://salesforce.stackexchange.com/questions/82149/lightning-components-can-helpers-call-other-helpers

The implementation mentioned in above link is:

Component: 
<aura:component > <input type="button" onclick="{!c.buttonClicked}" value="Click Me" id="myButton" /> </aura:component>
Controller: 
({
               buttonClicked : function(component, event, helper) 
               { 
                helper.changeMyLabel(component, event.target.id); 
                }
})
Helper: 
({
    changeMyLabel : function(component, buttonId) 
    {
        var newLabel = 'My Label Changed';
        this.changeButtonLabel(component, buttonId, newLabel);  
    },
    changeButtonLabel : function(component, buttonId, newLabel)
    {
        document.getElementById(buttonId).value = newLabel;
    }
})

I hope this helps and in case if this comes handy can you please choose this as the best answer so that it can be used by others in the future.

You would do this in a function.
a:funtion(component,event)
{
        var helper = this;
       …………
.      helper.b(component,event,1);

}
