Hello I am trying to automate my IE to log into a website but the problem is that the input elements do not have an HTML ID attribute! For example:
<input type="text" name="user" size="15" value="">
How do you program C# to insert text in this text box?
Thanks
Add the following attributes to your input tag: runat="server"
and id="someId"
<input id="user" type="text" size="15" runat="server">
Then server-side you do:
user.Text = "sample text";
Then you can do something like:
foreach (Control c in Page.Controls)
{
TextBox t = c as TextBox;
if (t != null)
{
t.Text = "sample text";
}
}
But I'm not sure it'll work without the runat="server"
attribute
I know this is a bit late, but here is an alternate to the jquery method.
I assume with IE you mean the webbrowser control. Once you have the document, you can go through the input -elements.
Something like
HtmlElementCollection inputs = browser.Document.GetElementsByTagName("input");
Then you loop through each of the inputs. You can check the input's name with
input.GetAttribute("name").Equals("user")
Inserting value to the field would be done with
input.SetAttribute("value", "MyUserName");
I guess this isn't "doing it programatically with C#", but you could jQuerify the page, then run some custom javascript afterwards, to manipulate the value of the control. If you are using WebBrowser
, you could call the below method to insert the scripts.
string script = "script text";
WebBrowser.Navigate(script);
var s=document.createElement('script');
s.setAttribute('src','http://jquery.com/src/jquery-latest.js');
document.getElementsByTagName('body')[0].appendChild(s);
$(document).ready(function(){$('input[type="text"][name="user"]').val('FooBar')});
Maybe this can help:-

Create a new project like a Windows form application project,
Add references of MSHTML ie Microsoft HTML Object Library plus SHDocVw ie Microsoft Internet Controls,
Create a function with body somewhat like and bound it to anything like a button's click event:
/*INTERNET EXPLORER's OBJECT*/
SHDocVw.InternetExplorer ie = new SHDocVw.InternetExplorer();
ie.Navigate("http://www.example.com/entry"); /*GO TO EXAMPLE.COM*/
/*WAIT UNTIL THE BROWSER IS READY AND COMPLETELY LOADED*/
while (ie.ReadyState != SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE)
{
Application.DoEvents();
}
mshtml.HTMLDocument doc = ie.Document;
while (doc.readyState != "complete")
{
Application.DoEvents();
}
/*GET ALL THE INPUT ELEMETS IN A COLLECTION*/
MSHTML.IHTMLElementCollection collection=
doc.getElementsByTagName("INPUT");
foreach (mshtml.IHTMLElement elem in collection)
{
if (elem.getAttribute("name") != null)
{
/*IDENTIFY THE INPUT CONTROL BY NAME ATTRIBUTE*/
if (elem.getAttribute("name").Equals("user"))
{/*ENTER USER NAME*/
elem.setAttribute("value", "ABC");
}
}
}
