long string of webview dialog will be cut

This is a example to show this issue.

0.24.4-sdk does not have this proble.

0.37.1-sdk and other versions have this proble.

about this example

I create a nw app.

The nw app's main page has a webview.

The webview load a local index.html file in folder ./static/html/

and a local index.js file in ./static/js/.

The webview will prompt a long strig and the main page

will catch this dialog event.

I found the long string will be cut in some vesions of sdk.

0.24.4-sdk

run the example:

1. install nw and use 0.24.4-sdk

npm install -g nwjs

nw install 0.24.4-sdk

nw use 0.24.4-sdk

2. clone this project and install dependencies

git clone https://github.com/caijw/nwjsApp.git

cd nwjsApp

npm install

3. run the static files server

cd nwjsApp

node ./server.js

4. run nw app

cd nwjsApp

nw .

assert result:

The assert result goes well.

Dialog messageText is unbroken.

		webview.addEventListener('dialog', function (event) {

			var messageText = event.messageText;
			assert.strictEqual(messageText, getLongText());
			
		});
