PhoneGap: How to pass parameters to the index.html from the Activity class

[karan]

Hello,

I am developing on Android OS.

My activity class loads the index.html as below:

super.loadUrl("file:///android_asset/www/index.html");

1) I needed to send some parameters to the index.html

2) Then read these parameters in the index.html via javascript.

Please help.

Thanks

karan

i think You have to put a Boolen value which  while your application is start, when on ready function you can paost that value,

Hi Karan,

it's dead simple once you see it (because we all have seen it before)... you go

super.loadUrl("javascript: { var myVariable = "I can push any javascript from Android Container to the DOM!"; document.body.innerHTML += myVariable; }");

after you loaded whatever html page you like.The above line is written straight from the head so test yourself, but if you want to see it working in a class you can take a look at the two files found here: https://github.com/Philzen/WebView-MultiTouch-Polyfill/tree/master/src/com/changeit/wmpolyfill

MainActivity basically is the same as yours, WebClient-Class hooks in, can intercept user actions at any time and/or inject javascript code into the webview.

Hope this helps.

Cheers - Phil

You can use html5 localStorage or sessionStorage to do that as well.

In your activity class initialize a javascript session variable like this

this.sendJavascript("sessionStorage.setItem('varName','varValue')");

and you can use this after your index.html has loaded.

I have another similar issue. Once the html is loaded and working; is there a way to call a javascript function of the loaded html from the activity class. 

Basically i have a mixed UI, half is native controls and half is phonegap html. On a native button click an event is sent back to the activity class, then in this event handler i need to send a parameter to the already loaded html view and then call its javascript function.

Its like this:

Step1: Activity class loads native controls and phonegap-html

Step2: User clicks on native control button, an event is fired

Step3: The activity class has the event handler for the button. 

Step4: In this activity-class event handler some new parameter has to be passed to the already loaded phonegap html.

Step5: Then the activity-class event handler has to call a javascript function inside the loaded phonegap html.

Please help.

Thanks alot

hi Phil if to send data from android to javascript is this,

super.loadUrl("javascript: { var myVariable = "I can push any javascript from Android Container to the DOM!"; document.body.innerHTML += myVariable; }");

what If I want the vice versa sending data from javascript to android?
