Issue in returning value within a js function about webviewjavascriptbridge HOT 3 CLOSED

Hi Murli,

Since "return" is synchronous and communication with objc is asynchronous you will not able to use "return" to give back a value from objc. You will have to use a callback function.

Hi
I have been struggling with an issue for the past few days.The issue is
We have a html page which communicates wih th javascript file teh javascript file in turn communicates with the native ios code of the app using your webview javascript bridge.The problem is
in the following js function we are calling a function of another javascript file

TheApp.getAppVersion = function()
{
var vpbVersion = VestaPhoneBridge.GetUserAgent().version;

if(vpbVersion != null)
{
return ""+vpbVersion;
}

return null;

};

The above method is calling a function in another .js file which is as follows:

VestaPhoneBridge.GetUserAgent = function(_callback)
{
bridge.callHandler('initiateGetUserAgentFunc','test', function(response)
{

                                     //getting response here from native     
                })

};

The problem is in the function "bridge.callHandler('initiateGetUserAgentFunc','test', function(response) " inside the above function
we are needed to return a value but we need to return the value to VestaPhoneBridge.GetUserAgent instead of "bridge.callHandler('initiateGetUserAgentFunc','test', function(response)"
The problem is we cannot use callback function in js also.The only thing is we have to return a value.
So it would be really great if you could suggest some solution for this problem.

Thanks
