Description |
|---|---|

controlname |
The name of the WebBrowser control. |

The message (in simple string format) to be sent to the top-level document, for example: "{'a': 'b'}"

Return value
Integer.
Returns 1 if the function succeeds and a negative value if an error occurs. If any argument's value is null, the method returns null.
Usage
In the top-level document of WebBrowser, the web message can be subscribed or unsubscribed through the following JavaScript:
window.chrome.webview.addEventListener('message', handler)window.chrome.webview.removeEventListener('message', handler)This behaves in exactly the same manner as PostJsonWebMessage, but the data property of the event arg of the message is a string with the same value sent by this function PostStringWebMessage. Use this instead of PostJsonWebMessage if you want to communicate using simple strings rather than JSON objects.
Examples
This example sends the specified string webMessage to the top-level document.
//window.chrome.webview.addEventListener('message', arg => {
// window.chrome.webview.postMessage(JSON.stringify(arg.data));
// });
Integer li_return
li_return = wb_1.PostStringWebMessage("testStr")
