Call A Javascript Function From The Activity?

How can I call a function in a HTML doc that is loaded into a webView with a button that is in my activity? ie: An ImageButton (called: bookBtn) is in the title bar of the activit

Solution 1:

There are at least two problems in the code:

1) The javascript URL doesn't invoke the loadTOC function, it just references it. What you want is:

mWebView.loadUrl("javascript:loadTOC()");

2) The loadTOC function isn't globally visible AFAIK, so the javascript URL won't be able to access it.

You should also make sure that JavaScript is enabled as no-good-at-coding suggests.

Solution 2:

I don't see in here so I'm going to add that you ought to make sure you have

mWebView.setWebChromeClient(new WebChromeClient());
mWebView.getSettings().setJavaScriptEnabled(true);.

in your Android code
