用WebView加载url后,我可以在表单页面中插入一些数据吗?
我尝试:
@Override
public void onPageFinished(WebView view, String url) {
String user="pippo";
String pwd="secret";
view.loadUrl("javascript:document.getElementById('j_username').value = '"+user+"';document.getElementById('j_password').value='"+pwd+"';");
}
但是没有工作......
HTML源代码为:
<html>
....
<form action="/.../" method="post">
<table align="center">
<tr>
<td>
<table>
<tr>
<td>User:</td>
<td><input name="j_username" type="text" tabindex="1"></td>
</tr>
<tr>
<td>Password:</td>
<td><input name="j_password" type="password" tabindex="2"></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="Login" tabindex="3"></td>
</tr>
</table>
</td>
</tr>
</table>
<!--</form>-->
</form>
...
<\html>

首先将您的数据导入所有Strings
并将其转发到您想要的类:
class MyJavaScriptInterface {
private Context ctx;
MyJavaScriptInterface(Context ctx) {
this.ctx = ctx;
}
@JavascriptInterface
public void showHTML(String html) throws JSONException {
System.out.println(html);
JSONObject jsonResponse = new JSONObject(html);
String sts = jsonResponse.getString("status");
if (sts.equals("success")) {
message = jsonResponse.getString("msg");
approved_status = jsonResponse.getString("approved");
jsonObj = jsonResponse.getJSONObject("data");
user_email = jsonObj.getString("user_email");
phone_no = jsonObj.getString("phone_no");
user_gender = jsonObj.getString("gender");
first_name = jsonObj.getString("first_name");
last_name = jsonObj.getString("last_name");
ids = jsonObj.getString("id");
id = Integer.parseInt(ids);
}
}
如果您的最后一页位于HTML
,请使用此代码:
@Override
public void onPageFinished(WebView view, String url) {
wb.loadUrl("javascript:window.HtmlViewer.showHTML"
+ "(document.getElementsByTagName('pre')[0].innerHTML);");
}
