can I autofill input fields by code?

[pipiscrew]

in IE

            var theBrowser = (WebBrowser)wb;
            HtmlElement inputElementByName = GetInputElementByName("j_username", theBrowser);
            if (inputElementByName == null) return;
            inputElementByName.SetAttribute("value", "x@x.x");

in CefSharp (?)

thanks

wow! lets see!!

[amaitland]

@pipiscrew Happy to close this one?

[pipiscrew]

sorry for the delay, I done something like

        //the browser
        private readonly WebView web_view;

        public Form1()
        {
            InitializeComponent();

            web_view = new WebView("http://y.com/", new BrowserSettings());
        }

        private void button1_Click(object sender, EventArgs e)
        {
            web_view.ExecuteScript("document.getElementById('email').value=" + '\'' + "takis" + '\'');
            web_view.ExecuteScript("alert('test');");
        }

worked!

thanks for the quick responses.

Excellent - thanks for sharing 👍 (and following up with closing) Marking as ``faq-able!`

@pipiscrew Out of curiosity are you still using CefSharp1?

[pipiscrew]

@amaitland , I downloaded the CefSharp-v1.25.8-binaries from releases and using the lib, what are you mean by CefSharp1 ? the dlls built on 12/2/2015..

user_agent = Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.152 Safari/537.22

wow, https://github.com/cefsharp/CefSharp/releases

the latest is
DEC 22, 2014, Chromium 39.0 / CEF 3.2171.1949

I downloaded the first one, seems incorrect.. is not the latest :(

please advise + whats new(?)

[amaitland]

CefSharp1 is an old legacy version. v1.25.8 is based on Chromium 25. It's no longer officially supported (upstream work on it has ceased). One of the project maintainers released that particular version for his own personal requirements.

The official release is 37.0.0 which is based on Chromium 37. The next release (which will be in the next few weeks will be 39.0.0 which is based on you guessed it, Chromium 39.

We don't release binary versions in zip form anymore, they're all released as nuget packages.

[amaitland]

I'd personally be using at a minimum version 37

[pipiscrew]

what new (?) beside chromium updates, please.

thanks for warning

[amaitland]

Too many things to list individually. Feel free to look at the changelog.

https://github.com/cefsharp/CefSharp/wiki/ChangeLog

[amaitland]

(The fact that we no longer support CefSharp1 is a pretty big thing IMHO)

[pipiscrew]

oh my god :)

I have to do a remake of the app :)

thanks for update me...!

check the freewares at http://bit.ly/1FT21o9

I have to do a remake of the app :)

In my experience it usually takes about 5-15mins to upgrade, a few things have changed, like WebView = ChromiumWebBrowser, that's the big one that gets most people.

check the freewares at http://bit.ly/1FT21o9

Is that a link to your app?

[pipiscrew]

with v39pre2 dlls, I replace WebView with ChromiumWebBrowser as you mention above

        public Form1()
        {
            InitializeComponent();

            web_view = new ChromiumWebBrowser("http://x.com/api/");
            web_view.LoadCompleted += new LoadCompletedEventHandler(web_view_LoadCompleted);
            web_view.Dock = DockStyle.Fill;
            panel1.Controls.Add(web_view);
        }

        //url watcher for autofill
        void web_view_LoadCompleted(object sender, LoadCompletedEventArgs url)
        {
            if (url.Url.ToLower().StartsWith("https://www.x.com/login.php?skip_api_login"))
            {
                web_view.ExecuteScriptAsync("document.getElementById('email').value=" + '\'' + General.login_name + '\'');
                web_view.ExecuteScriptAsync("document.getElementById('pass').value=" + '\'' + General.login_password + '\'');
                web_view.ExecuteScriptAsync("document.getElementById('login_form').submit();");
            }
        }

        private void toolStripButton1_Click(object sender, EventArgs e)
        {
            CEF.VisitAllCookies(d);
        }

*referenced dlls : *
CefSharp.dll
CefSharp.WinForms.dll

[jankurianski]

Use Cef instead of CEF and FrameLoadEnd instead of LoadCompleted: https://github.com/cefsharp/CefSharp/blob/master/CefSharp.WinForms/ChromiumWebBrowser.cs#L204

[pipiscrew]

thanks for the quick response

[edit]
CefSharp.Core.dll needed..

also the new version it doesnt appear on form! I have to use it on tabs (aka BrowserTabUserControl) ?

[jankurianski]

If the browser doesn't appear on the form when you run it, try going through these troubleshooting steps (particularly point 4): https://github.com/cefsharp/CefSharp/wiki/Trouble-Shooting

You should see a process called CefSharp.BrowserSubprocess.exe running in Task Manager.

[pipiscrew]

Im on x64 machine, using x86 libs as

then get files (as you suggested^) from NuGet

the same I got a blank form!

[edit]

Cef.Initialize(new CefSettings()); --> REQUIRED!

        public Form1()
        {
            InitializeComponent();

            Cef.Initialize(new CefSettings());

            web_view = new ChromiumWebBrowser("http://google.com/");

[pipiscrew]

So, finally all functions working as constructed for v1.25.8...

ps - CefSharp3 is a monster!!

thanks

[jankurianski]

@pipiscrew What did the problem turn out to be in the end? Anything you can share with future CefSharp 1 -> 3 upgraders like yourself?

[pipiscrew]

as described above^

except turn type :

WebView to ChromiumWebBrowser

before instantiate ChromiumWebBrowser must initialize Cef

thanks!

[vip3r011]

what if your login form is like this below, what do i use then?

<input class="form-control" placeholder="Username" name="name" type="text">
<input class="form-control" placeholder="Password" name="password" type="password" value="">
<input class="btn btn-lg btn-primary btn-block" id="submit" type="submit" value="Login">

[pipiscrew]

last time I used was at 2015, dont know for newer version, as written above use Javascript code and execute it with Webview as (in the following example set the word takis to element has name="email") :

web_view.ExecuteScript("document.getElementById('email').value=" + ''' + "takis" + ''');

see the 2nd reply for details

[vip3r011]

the answer for my previous question:

void browser_FrameLoadEnd(object sender, FrameLoadEndEventArgs e)
{
    if (e.Url.ToLower().StartsWith("https://sitehere/login.html"))
    {
        browser.ExecuteScriptAsync("$('input[name=name]').val(\"user\")");
        browser.ExecuteScriptAsync("$('input[name=password]').val(\"password\")");
    }
}

[GlennIM]

This code worked for me too as shown above...

    browser.ExecuteScriptAsync("$('input[name=name]').val(\"user\")");
    browser.ExecuteScriptAsync("$('input[name=password]').val(\"password\")");

But how did youI execute the submit button code below?

[pipiscrew]

@GlennIM

if you form has id = login_form

web_view.ExecuteScriptAsync("document.getElementById('login_form').submit();");

more samples @ https://bit.ly/2vBOEZm

[chipotlejess]

I tried using the following, it didn't throw any errors but when I load the page, it doesn't plug the values into any of the fields...

private void browser_FrameLoadEnd(object sender, FrameLoadEndEventArgs e) { if (e.Url.ToLower().StartsWith("https://website.com")) { browser.ExecuteScriptAsync("$('input[name=Username]').val(\"user\")"); browser.ExecuteScriptAsync("$('input[name=Password]').val(\"user\")"); } }

I make sure to include
Cef.Initialize(new CefSettings());

P.S. I'm pretty new and still learning...

[totti240282]

but with CEF is possible use also Jquery for select elements ?

[pipiscrew]

@chipotlejess, as @totti240282 says. Use vanilla JS :

document.getElementsByClassName('APassAttr')[0].value = 1 //element selector by CLASS (returns an array, then grab the first)

document.getElementsByName('activityTime')[0].value = '00'; //element selector by NAME (returns an array, then grab the first)

document.getElementById('CountryLocationAddress').value = 4020; 

[ghost]

But how can i input the value onto the ID using CefSharp on VB .NET

[pipiscrew]

see this

[ghost]

okay that looks pro level, so i found this code snippet:

Dim EmailScript As String = <js><![CDATA[document.all("variable1").value = 'variable2';]]></js>.Value

        browser.ExecuteScriptAsync(EmailScript)

I can't get this to work because of the variables. How do I add VB.NET variables to a javascript code (the one above). Variable1 is string value which the user inputs in a TextBox and variable 2 is a constant string value.

Got this working out? Just curious.

[darkanqeltr]

    private void browser_FrameLoadEnd(object sender, FrameLoadEndEventArgs e) { if (e.Url.ToLower().StartsWith("https://website.com")) { chrome.ExecuteScriptAsync("$('input[name=Username]').val(\"user\")"); chrome.ExecuteScriptAsync("$('input[name=Password]').val(\"user\")"); } } How can I use this code? I have to fill the form automatically and login. Thank you
