EonX 接收事件

The EON Web Publisher wizard can generate controls (buttons or image links) that send in-events and text fields where out-event values are shown. To do this you must use the right template. Read about this in Step 2 of the Eon Web Publisher wizard.
Possible problems
If the data type is wrongly spelt then you will get an alert saying 'Unrecognized EON datatype' and the event is not sent. If the event name is wrongly spelt then nothing will happen because the EON Application cannot accept it. No alert message is sent. If you send in values that don't match the data type then again nothing will happen. The event cannot enter into EON.

Sending and Receiving Events
Introduction
This page will help you understand how to send events between the web page and the EON Application. There are two types of events, in-events and out-events. An in-event is information that you send from your Web page using JavaScript to the EON Application, which is embedded in the html page. An out-event is information coming out from EON to the web page. To avoid confusion about what an out-event is and what an in-event is, always think relative to the EON Application.

<a href="javascript:EONSendEvent('SFBool', 'Lights', false)"><img src="images/lightoff.gif" border=0 alt="Turn off the lights" width=36 height=36></a>
The above functions are written in JavaScript. You put this JavaScript in your HTML page and it gets embedded in the html. Here are a few examples of common html elements with inserted functions.
Sending an event when the user clicks on an input button is done like this:
<form><input type="button" value="Turn off the lights" onclick="EONSendEvent ('SFBool', 'Lights', false)"></form>
Here is the code for sending each different data type:
EONSendEvent('SFBool', 'MyEvent', true) EONSendEvent('SFColor', 'MyEvent', 1, 0.5, 0) EONSendEvent('SFFloat', 'MyEvent', 12.25) EONSendEvent('SFInt32', 'MyEvent', 22) EONSendEvent('SFRotation', 'MyEvent', 10, 9, 8, 7) EONSendEvent('SFString', 'MyEvent', 'Hello') EONSendEvent('SFTime', 'MyEvent', 9600) EONSendEvent('SFVec2f', 'MyEvent', 0.2, 0.8) EONSendEvent('SFVec3f', 'MyEvent', 0, -10, 2)
This inevent control is designed to send the value 'Hello EON' to the 'RoomText' in-event. This might be used to display a tooltip when the user positions the mouse over a room. To make it sent another value just replace the 'Hello EON' text with your own. For example 'Conference Room'.
A common problem can be that you send in SFBool event with value True but it is acting as if it is receiving false. This is because JavaScript is case sensitive so if you write True with a capital T then it treats it as not true. For JavaScript to send true you must use true. Anything else will be false which includes TRUE, True, 'true' or "true".
If clicking on an image should send the event then write it like this:
mk:@MSITStore:C:\Program%20Files\EONБайду номын сангаас20Reality\EON%20Studio\Help\U... 2007-11-16
Receiving out-events from EON
The function that receives the events must be called EON_OnEvent(e, v) where e represents the event's name and v the value. V will be an array when the events' data type has multiple values.
Sending in-events to EON
This is the function used to send in-events:
EONSendEvent(EONdatatype, EventName, Value1, Value2, Value3, Value4)
EONdatatype represents the type of values you are sending like a Boolean, integer or string. There are currently 9 supported data types of a possible 22. These are SFBOOL, SFCOLOR, SFFLOAT, SFINT32, SFROTATION, SFSTRING, SFTIME, SFVEC2F, and SFVEC3F. You may use upper, lower or mixed case for the data type as they are converted to upper case before sending by eon_functions.js
