Merge two functions?

Say, I have two functions:

function foo() {
  this.lorem = 'ipsum';
}

function boo() {
  console.log(this.lorem);
}

And I want to insert the boo function at the end of the foo function so that they can share the same this. How would I do it? 开发者_JS百科

Like this?

function foo() {
    this.lorem = 'ipsum';
    console.log(this.lorem);
}

In all seriousness, your question is not clear enough to be reliably answered.

In the event you want to keep them separate:

function foo() {
  this.lorem = 'ipsum';
  boo(this);
}

function boo(element) {
  console.log(element.lorem);
}

---

Wrap them both under the same context:

var myClass = {
    foo: function foo() {
        this.lorem = 'ipsum';
        this.boo();
    }, boo: function boo() {
        alert(this.lorem);
    }
};

Then to activate foo:

myClass.foo();

Live test case.

---

function foo() {
  this.lorem = 'ipsum';
  boo.call(this);
}

function boo() {
  console.log(this.lorem);
}

foo();

---

If you don't want to modify the existing functions do this:

function foo() {
  this.lorem = 'ipsum';
}

function boo() {
  console.log(this.lorem);
}


function bar() {
    boo.call(new foo);
}

bar();
