And the demoFlashChat.fla with 2 input text: text1 and statusField,with as code like:
import flash.external.ExternalInterface;
#include "..\lib\lsjavascriptbridge.as"
_root.text1.text = "";
_root.statusField.text = "WAITING";
function bridgeIsReady() {
_root.statusField.text = "Bridge ready";
}
function statusChange(newStatus) {
_root.statusField.text = newStatus;
}
function myOnStart() {
_root.text1.text = "";
}
function [COLOR="Red"]myOnItemUpdate[/COLOR](itemPos,itemObj,itemName) {
if (itemPos == 1) {
if (itemObj.isValueChanged(1) == true) {
_root.text1.text = itemObj.getNewValue(1);
}
}
}
var bridge = new JavaScriptBridge("flashObject");
bridge.onReady = bridgeIsReady;
bridge.onStatusChange = statusChange;
var myTable = new FlashTable("chat_room", null, "DISTINCT");
myTable.setDataAdapter("CHAT_ROOM");
myTable.setSnapshotRequired(true);
myTable.onItemUpdate = myOnItemUpdate;
myTable.onStart = myOnStart;
bridge.addTable(myTable,"FlashTable1");
bridge.bind();
2 above code file are combined from 2 your demo: ChatDemo and Flash_StockListDemo_Basic. But it can't run.I don't know. The problem maybe in callback function:
myOnItemUpdate,because when I try put a code line as:_root.text1.text = "test" in this function(I'm so sorry, because now I only know debug like that in Flash), it don't display, but in your example(Flash_StockListDemo_Basic), a same line will display.
The above example only make a simple work: when user type a text line on HTML form, it transmit to LS server, then back to
text1 variable in Flash, and display.
Thanks for your help!
