My html page contains one checkbox and some content inside
. I also have Save button. When I click the开发者_StackOverflow中文版 Save button I should get the content of the hidden fields inside the html page in My Activity .IS that possible. pls help me.Finally I got the problem resolved.. In my activity I added a JavaScript interface with a javascript function named saved() in it.In my html page I added a javascript function named clicked().In this function I collected all the values as a String and passed to the saved(). The saved() function is in my activity and so I could use the values in my Activity.
In Oncreate()
{
mWebView.addJavascriptInterface(new DemoJavaScript(),"demo");
mWebView.loadUrl("file:///android_asset/index.html");
}
final class DemoJavaScript {
DemoJavaScript() {
}
// This is the javascript function
public void saved(String values) {
Toast.makeText(getApplicationContext(), values, Toast.LENGTH_SHORT).show();
}
}
// my html page
<script language="JavaScript">
var values;
function clicked()
{
values="";
values=document.getElementById('myvalue');
window.demo.saved(values);
}
</script>
