## Basic code
```
<script type="text/javascript">
//Send message to web ui
function sendMessage(msg){
window.parent.postMessage(msg, '*');
}
//Process Message coming from webUI
function processMessage(eventMsg){
//now process eventMsg.data
}
//Setup message listener from webUI
window.onload = (event) => {
window.addEventListener("message", processMessage, false);
};
</script>
<div class="container">
Display your HTML here
</div>
```
As you can see code is minimal - it will fit a Frame, webui css / theme will be added by webUI after loaded, so you do not need to add any, you can use any of existing class available in webUI.
Communication between frame and main window is done by messages using objects (string / array based), do not use any object that could ne be cloned or loading will fail.
---
### Send message
message structure used by `window.parent.postMessage(msg, '*');` has a defined format, some parameters are madatories, some are optionals and some depend on message type:
`{type:'<message type>', target:'webui', id:'[origin]', noDispatch:[true], XXX:YYY}`
`<message type>` is mandatory, it define the purpose of the message
`target:'webui'` is mandatory, it help to screen the message
`id:'[origin]'` is optionnal, it define which id must read the response if any, if present it can be used by extension to filter message, no id means the message is for everyone
`noDispatch:[true]` is optionnal, if true it will prevent to send answer if any, if not or set to false, it will send answer message if any
`XXX:YYY` are optionals/mandatories according message type
---

### Modal Dialog Documentation
This documentation describes how to use the modal dialog functionality. The modal dialog is a pop-up window that displays a message to the user and requires the user to respond before they can continue. The modal dialog can be used to display simple messages, confirmations, input fields, and multiple input fields.
#### Modal Types
The code supports four types of modal dialogs:
1. Simple Modal: Displays a basic modal with a title, text, and a single button.
2. Confirmation Modal: Displays a modal with a title, text, and two buttons for confirmation.
3. Input Modal: Displays a modal with a title, text, an input field, and two buttons.
4. Fields Modal: Displays a modal with a title, multiple input fields, and two buttons.
#### Sending Messages
To open a modal dialog, you need to send a message to the parent window using the `sendMessage` function. The message should have the following structure:
```javascript
sendMessage({
type: 'modal',
target: 'webui',
id: 'modalpanel',
content: {
// Modal-specific content
}
});
* type: Always set to 'modal'.
* target: Always set to 'webui'.
* id: Set to 'modalpanel' for all modal types.
* content: An object containing the modal-specific content.
#### Modal Content
Each modal type has its own specific content structure:
1. Simple Modal
Example:
```json
{
type:'modal',
target:'webui',
id:'modalpanel',
content:
{
title:'This is title',
id:'simple_modal',
style:'default',
bt1Txt:'S126',
response1:'ok',
text:'some text',
overlay:true
}
}
```
- **type** (mandatory): 'modal'
- **target** (mandatory): 'webui'
- **id** (optional): 'modalpanel'
- **content** (mandatory): Modal description
- **title** (mandatory): Title of the modal. Use predefined text for translation.
- **id** (mandatory): Modal ID. Example: 'simple_modal'
- **style** (mandatory): Modal style. For simple modal, use 'default'.
- **bt1Txt** (optional): Text for button 1. 'S126' will be translated as 'Ok'. If not defined, the button won't be displayed.
- **response1** (optional): Message sent if button 1 is clicked. Example: 'ok'. The click closes the modal.
- **bt2Txt** (optional): Text for button 2. If not defined, the button won't be displayed.
- **response2** (optional): Message sent if button 2 is clicked. The click closes the modal.
- **hideclose** (optional): If set to true, it hides the close button of the modal.
- **overlay** (optional): If set to true, it automatically closes the modal if it loses focus.
- **text** (optional): Text to display in the modal. If it's a predefined text, it will be translated.
Note: The close button and overlay feature won't send any notification when the modal is closed.

#### Handling Messages
The code listens for messages from the parent window using the handleMessage function. When a message is received, it checks the type and id properties to determine if it's a modal-related message.
If the message is a modal response, it logs the clicked button (line.response) and performs specific actions based on the modal type and response.
For the Fields Modal, if the response is 'create' (response1 because validation is bt1), it updates the defaultSettings object with the values entered in the fields (line.inputData).
For the Input Modal, if the response is 'create' (response1 because validation is bt1), it displays the entered input value (line.inputData).
