I am calling javascript function from an activity but I am getting Uncaught ReferenceError: myFunction is not defined at null:1 error. Here is my files
MainActivity.java
package com.example.androidexample;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.view.Menu;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView webview = (WebView)this.findViewById(R.id.webView1);
WebSettings webSettings = webview.getSettings();
// Enable Javascript for interaction
webSettings.setJavaScriptEnabled(true);
// Make the zoom controls visible
webSettings.setBuiltInZoomControls(true);
// Allow for touching selecting/deselecting data series
webview.requestFocusFromTouch();
// Set the client
webview.setWebViewClient(new WebViewClient());
webview.setWebChromeClient(new WebChromeClient());
//webview.loadUrl(file:///android_asset/test.html);
/*String str = <books> +
<book title=A Tale of Two Cities/> +
<book title=1984/> +
</books>;*/
webview.loadUrl(file:///android_asset/test.html);
webview.loadUrl(javascript:myFunction());
//webview.loadUrl(javascript:myFunction(+str+));
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
test.html
<html>
<body>
<script type=text/javascript src=marknote.js></script>
<script type=text/javascript>
function myFunction()
{
var str = '<books><book></book></books>';
var parser = new marknote.Parser();
var doc = parser.parse(str);
var bookEls = doc.getRootElement().getChildElements();
for (var i=0; i<bookEls.length; i++) {
var bookEl = bookEls[i];
alert(Element name is + bookEl.getName());
}
}
</script>
</body>
</html>
I have seen this error occurred when I am using webview.loadUrl(javascript:myFunction());. I want to pass a xml string from java and parse it into javascript. Please help me to find a solution.
