Question

I have this view:

<script type="text/javascript" src='<%: Url.Content("~/Scripts/new.js") %>'></script>
<div class="col1">
  Number of Questions:
</div>
<div class="col2-input" id="no-of-questions-value">
  <input type="hidden" name="NumberOfQuestionsHidden" id="NumberOfQuestionsHidden" value="<%: Model.NumberOfQuestions %>" />
  <%: Html.TextBoxFor(model => model.NumberOfQuestions) %>
</div>
<div class="col3">
  <div id="save-no-of-questions-button">
    <a href="javascript:saveNoOfQuestions();" class="button">Save</a>
  </div>
</div>

and the new.js where I determine the values: this js runs a scorm module and logs each event as I go through the questions in the scorm module, I count all correct and all incorrect then I know how many questions were asked.

 function LogEvent(action,data)
 {
    if (data == "correct") {
       correct_count++;
       alert("incorrect count = " + incorrect_count + " correct count = " + correct_count);
 }

 if (data == "incorrect") {
    incorrect_count++;
    alert("incorrect count = " + incorrect_count + " correct count = " + correct_count);
 }

}

to get the total number of questions i add correct_count and incorrect_count and want to pass this to the view into Html.TextBoxFor(model => model.NumberOfQuestions).
I dont know how to go about this. any help please?

thanks

Answer 1

I wonder why you present the number of questions in a textbox, but still.. You can update your textbox value by:

document.getElementById('NumberOfQuestions').value = 'whatever you want';

This will work, since the default element ID is name of the model property.

To get the client ID clean way, you can read more here.
