How do you find elements when all you know is a part of its class?

Mar 15, 2009 11:03 PM|LINK

So here is the markup:

<a class="hni_Button hnine_KioskBottomNavBtnIndexEN hnine_KioskBottomNavBtn" href="http://juniper:2107/Default.aspx?machine=NBI0EjQSNBISNBI0EjQSNA&session=Y3L3y-aj_023IS_R_Tth9w&contentid=4488001">

What I want to do it this (but instead of the Id, I want to use the classname.)

public HtmlElement IndexButton
{
    get
    {
        return Page.Elements.Find("BtnIndex", TreatIdAs.Regex);
    }
}

Now I know I can do this to get the classname, but it only works with the full classname, not a partial!

         public virtual HtmlElement FindHtmlElementByClass(string className, string tagName, int timeoutInSeconds)
        {
            var findParams = new HtmlElementFindParams { TagName = tagName };
            findParams.Attributes.Add("class", className);

            return Page.Elements.Find(findParams, _defaultFindTimeoutInSeconds);
        }

Currently this functionality does not exisits. However, I will work on a fix for this and try to post it quickly. You can however modify the MatchAtributes method in HTMLElementFindParams if you need this quickly.

We have decide that we will try as hard as we can not to modify the framework code directly, we want to be able to quickly add your upgrades without a slow merge process. The thought being we are adopting this so early we do not want to be out of the loop for updates.

I did have a fix suggestion though :)

1) Mark TreatIdAs Obsolete.

2) Rename it to SearchMethodType (or some better name)

3) Use the new enum in the Find() method

4) Use the new Enum as optional in the Attributes.Add() method

The idea being I might want to mix and match attributes. Exact match on class, partial on href.

Hi,

Why not use the Javascript to match the class string.

<a id="ccscript" class="bober song ccscript" href="http://www.ccscript.cn">ccscript</a>
<script>
var classes=document.getElementById("ccscript").className.split(' ');
var bb="";
for(var i=0;i<classes.length;i++)
	bb+=classes[i]+"=";
alert(bb);
</script>< pre>

Then you can get the class array.

I see what you are suggesting, but I am testing remote pages that I do not have access direct access to. Maybe there is a way to insert my own scripts into the page before the browser gets it, but I would worry about my test scripts affecting the page.

The other problem is many of the elements I need to find don't have an id. For example:

<a class="hni_Button hnine_KioskBottomNavBtnIndexEN hnine_KioskBottomNavBtn" href="http://juniper:2107/Default.aspx?machine=NBI0EjQSNBISNBI0EjQSNA&session=Y3L3y-aj_023IS_R_Tth9w&contentid=4488001">

Hi,

mcowan

You can register the javascript and output from server.

public void ShowMessage(string message)
{
string strMessage = message;
string strScript = "&lt;script>alert('" + message + "'); </script>";
Page ParameterPage = (Page)System.Web.HttpContext.Current.Handler;
ParameterPage.RegisterStartupScript("alertmessage", strScript);
}

If you want to deal with the tag's class in the server,

you can use AJAX for keeping in touch with the server.

You can use document.getElementByTagName().

<script>
var as=document.getElementByTagName('a');
var bb="";
for(var i=0;i<as.length;i++)
{
 var classes=as[i].className.split(' ');
 for(var i=0;i<classes.length;i++)
  bb+=classes[i]+"=";
}
</script>

Bober, Am I missing something important? I do not understand your ShowMessage(string message) method and how it relates to running a WebTestMethod. What I am trying to do is test a webpage where I do not have access to the webpage code. Lets say for Example Google.com. Are you telling me that I can use some injected javascript against a site like google to figure out the classname? Would you mind please giving me at simple (but working) WebTestMethod that shows how to get the Google.com search button using Javascript? If there is a way to insert javascript into the reponse from a page request I am going to be happy!

I see the confusion in the responses to my posts. I apologize for my horrible communication skills in this thread. Let me clear things up.

I know HOW to use javascript when I am developing my own ASP.NET web pages. I don't need any help writing javascript code or syntax (but thanks for the jquery link, its cool)

What I am confused on, is that a previous post made it sound like it is possible to use the ASP.NET QA Lightweight Test Automation Framework to test http://google.com/index.html and use custom javascript INSIDE the test method (not on the google index.html page) to parse a classname.

I did not think it was possible to use javascript inside the C# test code to interact with webpages. If it is possible to inject javascript using this framework that would be AWESOME and I would love to know how to do it.

Michael, your suggestion sounds good and we are including it in our next release. Currently, its looking something like this (names may change):

<div>public enum MatchMethod</div> <div>{</div> <div> Literal,</div> <div> EndsWith,</div> <div> Contains,</div> <div> Regex</div> <div>}</div> <div> </div> <div>public class HtmlAttributeMatch</div> <div>{</div> <div> public string Name {get; set;}</div> <div> public string Value {get;set;}</div> <div> public MatchMethod ValueMatchMethod {get;set;}</div> <div> ...
}</div> <div> </div> <div>public class HtmlAttributeMatchCollection: List<HtmlAttributeMatch></div> <div>{</div> <div> public void Add(string name, string value) {...}</div> <div> public void Add(string name, string value, MatchMethod valueMatchMethod) {...}</div> <div>}</div>

One of the tricky things is how to deal with the current TreadIdAs. I am thinking of completely removing it instead of deprecating it, I mean we can fix the tests on our side relatively easily. Would you be ok with this?
