Couldn't find SendMessage function?

I'm using Unity5.0. And I'm trying to implement communications between browser and published webgl program.

Now the problem is I couldn't find SendMessage function. As this page mentioned, there should be a "SendMessage" funciton in UnityConfig.js: http://answers.unity3d.com/questions/825602/browser-to-unity-webgl-communication.html

However, When I build my project with WebGL, there is a UnityConfig.js, but no SendMessage within it.

Could anyone please help me?

 

Does anyone know how to solve this problem?

 

You ever find a fix? Would love to know the answer.

Edit: Just needed some patience. Everything has to be fully loaded. Here is my sample code from index.html:

Code (JavaScript):

1. <input type="button" id="move_up" onclick="moveUp()" value="Move Up" />
2.     <input type="button" id="move_down" onclick="moveDown()" value="Move Down" />
3.     <script type='text/javascript'>
4.   // connect to canvas
5.  
6.   function moveUp() {
7.     SendMessage("Cube", "MoveUp", "Testing");
8.     console.log("Attempting to Move Up");
9.   }
10.  
11.   function moveDown() {
12.     SendMessage("Cube", "MoveDown", "Testing");
13.     console.log("Attempting to Move Down");
14.   }

 

I was able to call a function from my a gameobject in my scene from my javascript code.

My scene was loading very slow, even when I only have two gameobjects inside it.
And because I called my function "SendMessage" before the page finish loading, a pop up with the error "SendMessage is not defined" appears.

-The steps to solve it were:

1-The form to call the funtion is :

function SaySomethingToUnity(_parameter_To_Send)
{
SendMessage("GameObject_To_Call", "Function_To_Call", _parameter_To_Send);
}
You DO NOT need to use ""u.getUnity()" anymore.
Remember that (SendMessage will then call the function Function_To_Call() on the game object named GameObject_To_Call, passing a piece of string, int or float, data as an argument)

2-Disable thee Exceptions in Unity(PlayerSettings->Publishing Settings->Enable Exceptions: None). This form, my scene was loading faster.
3-When everything was loaded. The "SendMessage" error did not appears anymore (the file UnityConfig.js that Unity generated when building does not have a definition for the function SendMessage, so do not look for it).
