Cognos Tree Prompt with Javascript on 10.2.1 (select all child on expand, select all child on parent selection and deselect all child on parent deselect)

Cognos Tree Prompt customization with Javascript 

Requirement:
1. When you expand a node, all the child nodes beneath it are checked and current node get deselected.

2. When you deselect the parent node, all the child nodes beneath it are deselected. 

3. When Select the parent node, all the child nodes beneath it are selected.
4. When any node selected or deselected its parent would be deselected.

Solution:

I have  copied some of code from below links to write my code.

Step 1: Create a tree prompt and give it the name “Time”. 
Step 2: Set Multiselect property of tree prompt to yes. 

Step 3: Drag an HTML item to the left of the tree prompt and add below code.

<div id='myTree'>

Step 4:  Drag HTML item to the right and add below code.

</div>

Step 5: Now drag one more html at right side finish button with below code
