Bug ID: 193530
Summary: [webkit2gtk][JavaScriptCore glib] typeof "API created
function" == "string"
Product: WebKit
Version: WebKit Local Build
Hardware: PC
OS: Linux
Status: NEW
Keywords: Gtk
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: crispyfrog at 163.com
I'm trying to use the JavaScriptCore glib API to define some native functions for use in user scripts, they work great so far, but somehow the js user script typeof doesn't recognize them as "function".
For example:
/* web-extension.c */
static void
zzz(void)
{
printf("zzz\n");
}
static void
windowobjectcleared(WebKitScriptWorld *w, WebKitWebPage *wp, WebKitFrame *frame,
gpointer unused)
{
JSCContext *ctx;
ctx = webkit_frame_get_js_context_for_script_world(frame, w);
jsc_context_set_value(ctx, "zzz", jsc_value_new_function(
ctx, "zzz", (GCallback)zzz, NULL, NULL, G_TYPE_NONE, 0));
}
/* user-script.js */
console.log(typeof 'zzz'); /* logs string instead of function */
console.log(zzz); /* function zzz() { [native code] } */
