[Gambas-user] Read data from localstorage in gb.web.gui

[Safiur Rahman]

Hi Bruce

The WebTextBox can be filled with value you receive from javascript on
client side and then you can update on server side.

WebForm._AddJavascript("var xdata = 'abcdef'")
WebForm._AddJavascript("$_(" & JS(WebTextBox1.Name & ":entry") & ").value =
xdata")

I am using it extensively. The only problem is it cannot hold big size
string.

There should be some mechanism to communicate between javascript on client
and gambas on server.
