I have a hidden div which by JavaScript gets filled with json text. I need to find this div and read the json text from it. How can this be done?
<html>
<div id="hiddenJSON">
{
"id":"1234",
"Name":"Jonas",
"Address":"Test Road 5",
"Phone":"1234-1234-1234"
}
</div>
</html>
On
try below code :-
Pattern p = Pattern.compile(Pattern.quote("<div id=\"hiddenJSON\">") + "(.*?)" + Pattern.quote("</div>"));
Matcher m = p.matcher(text);
while (m.find()) {
System.out.println(m.group(1));
}
But better solution is you have to receive data without html tag so talk with back end person.

Here is how i solved this:
result is the response from @JavascriptInterface
WebView Fragment
WebView wv = ...
wv.addJavascriptInterface( this, "android" );
wv.loadUrl( "javascript:android.showHTML(document.getElementById('hiddenJSON').innerHTML);" );
Interface in my WebView Fragment
@JavascriptInterface
public void showHTML( String result ) {
// handle JSON (result)
}
Problem: I had to get the result from my WebView in order to get the JavaScript to run (filling this hidden div with JSON).
It would be best to use a library for this such as
JSoup. Check out this question about parsing html code
