Dear users,
Since extjs, geoext, openlayers are javascript libraries, I've tried things
such as "eval" to make variables accessible in the code below but
no luck so far. I want to update or replace a variable (ie. in the protocol)
that is at first
null (so null in protocol and also outside formPanel), then defined with
something (ie. inside the handler function, is it right to define it there?)
and then
use it inside a variable (as proto in "protocol: proto", so replace the one is
already null), here is an example:
var proto = null; # <--- replace here (old "proto")
var formPanel = new GeoExt.form.FormPanel({
protocol: proto, # <--- or replace here (old "proto")
items: [{
xtype: "combo",
id: "idcombo",
etc...
}, {
xtype: "textfield",
id: "idtext",
etc...
}],
button:[{
text: "search",
handler: function() {
formPanel.search();
var combo = Ext.getCmp('idcombo').getValue();
var text = Ext.getCmp('idtext').getRawValue();
var proto: new OpenLayers.Protocol.HTTP({ # <-------
new "proto" to replace above
url: "http://www.pub.pub/"; + combo + "/rhen/" + text
}),
}
}]
});is is possible to use this new "proto" to replace the old "proto"? if so,
how can I do it?, not sure if new "proto" has to go in
the handler: function. I defined "var proto = null" at first because without it
the formPanel doesn't render due to "proto is not defined". I'll appreciate
your support, thanks in advance.
Best regards,
Gery
