Hello All:
I'm using WB v.22 and I have some JavaScript code running on the Browser side. Is there any way to share/access variables between JS and WL? I need to pass data to the JS function from the WL server functions.
Thanks

Clarification:
I actually have to call a Browser code in JavaScript from the server side, to pass new data. Is it possible to call browser code from the server side?
Thanks

| Server don't know anything about what is executed on client side, of course! Server just serves client requests. You can take some information from server using jQuery (AJAX) for example or learn the new feature of WD22 websockets. In any case initial request executed from client. |

| Yes! I also do what fabrice does! You can also pass parameters to a JS procedure from WL, Create a web procedure from WebDev, and change it to JS, in the parenthesis of your procedure declare the parameters you want to receive, and you can also retrieve values from the JS procedure with return or you can also use JS or JQuery to write some value in an EDT_, depending on the circumstance you may use this or the timer Fabrice told you, because when you execute a JS procedure your code will continue, without waiting for this procedure to finish, so sometimes your server side won't see the value your JS wrote in an EDT_, in this case is better to use a timer. |
