如何在C＃中使用IE从onclick元素中检索值

Question

I have been developing a project wherein I need to login in our internal server webpage and update values in the form and submit the data to server. The main issue is, on submitting or clicking on Save button, the Internet Explorer displays a pop up button saying, "Do you need to save the data, Yes or No?". Upon selecting yes, the data gets submitted and I get another pop up button displaying, "Data submitted". However, in case there is duplicate data, it shows a Validation error pop up showing, data already exists.I'm not able to capture the value returned by the method.

Since it is a internal server link and I can't post the screenshot or link from my company desktop, I'm sharing the bits of below HTML code from Internet Explorer.

<a id= "saveButton" onclick="submitter('Save'); return false;" href="" shape= "">

C# code

InternetExplorerMedium IE = new InternetExplorerMedium();
HTMLDocument hdoc = new HTMLDocument();
IE.visible = true;
IE.Navigate("Internal web server page");

After updating all the values in form, navigating to the Save button of the form using the below code

hdoc.all.item("saveButton").click();

So I need to get the return value of onclick element ie is it true or false. I have tried hdoc.parentWindow.execscript("submitter('Save'); return false;","javascript"); but it did nothing. It seems InvokeScript doesnt work with IE. Has anyone ever worked on such query?

Note - InternetExplorerMedium is the only way by which the internal server webpage is getting opened. InternetExplorer class was not of any help while loading the page.

<form name="myform" onsubmit="return submitter(event);" action="/account/login.php">
<label>name:<br/>
<input name="txtname" id="txtname" />
</label>
<label>secret:<br/>
<input type="password"/>
</label>
<input type="submit" value="Login"/>
<input type="reset" value="Reset"/>
</form>

<script type="javascript/text">
function submitter(evt){
// return true or false to allow the form to be submitted.
// do your field validations in this function.
}
</script>

To help you we need to see the markup and scripting of the internal web page you are trying to automate from C#.... It appears that that web page is incorrectly designed (does not use the above design pattern)...the process flow is 1. Load web page with a form on it. 2. User enters data into a form. 3. User clicks the submit button for the form... this triggers the form onsubmit event handler (submitter) which should then validate the data entered. If its valid submitter returns true and the form data is submitted to the server (action attribute of the form). If the data is not valid the submitter function return false, cancelling the onsubmit event handler.
