WebViews custom script

AppListo

WebViews custom script is a WebView option available to users with the Orange package. It allows injecting custom JavaScript code into WebViews used by the cloned app, which is executed after a WebView component has finished loading the page. In that sense it provides functionality similar to Firefox’s Greasemonkey or Chrome’s Userscripts.

A global object called callback is provided for the script to show dialogs, toasts and notifications. It also allows copying text into the clipboard.

By default, the script runs after the page has fully loaded. Some pages execute their own scripts during loading, so in those cases you can enable Inject mode to run your script earlier by inserting it directly into the page source before it loads.

By selecting Enable placeholders (Red package required) from the menu you can enable placeholder support for the JavaScript source (see also Placeholders).

Here some examples:

Showing a dialog

Provide the arguments title and message to showDialog().

(function() {
  // Show the page HTML source as a dialog
  callback.showDialog('Page source', document.body.innerHTML);
})();

Showing a toast

Provide the argument message to showToast().

(function() {
   // Show the page URL address as a toast
   callback.showToast(window.location.href);
 })();

Showing a notification

Provide the arguments title, text (optional) and highImportance (optional) to showNotification(). High importance notifications will be shown as heads-up notifications.

(function() {
   callback.showNotification('Text');
   callback.showNotification('Title', 'Text');
   callback.showNotification('Title', 'Text', true);
 })();

Using the clipboard

Use setClipboardText() to copy text into the clipboard and getClipboardText() to get the current clipboard text.

(function() {
   callback.setClipboardText(document.body.innerHTML);
   // Log clipboard text to Android logcat
   console.log(callback.getClipboardText());
 })();
