How to add validation on form dashboard input textfield?

thanks all in advance for your time.
I am trying to create a field validation on my dashboard. My fieldset on dashboard is following:

<fieldset autoRun="true" submitButton="true" >  
<input type="text" token="startdate" searchWhenChanged="true" name="sdate" id="sdate">
  <placeholder>Last Month</placeholder>
  <default></default>
  <label>Select a Start Date:</label>
</input>
</fieldset>

And I am trying to retrieve values from my dashboard with the following JS code in app/static directory:

var unsubmittedTokens = mvc.Components.get('default');
var submittedTokens = mvc.Components.get('submitted');
var urlTokens = mvc.Components.get('url');
var startDate = mvc.Components.get('sdate');
submittedTokens.on('change:startdate', function(){
    // When the token changes...
    if(!submittedTokens.get('startdate')) {
        alert("no token");
    } else {
        alert("got a token");
        var startdate = document.getElementsByName('sdate').value;
        alert(startdate);
    }
});

I couldn't start my validation functions since somehow I can't get value of the field to JS.
I want my validation to work in input textfields whenever a field value changes.
I can get value "undefined" with getelementbyName function above. But I can't get what user entered into textfield.

I would be appreciated if someone can help me with above, moreover, if there is an easier way to validate fields on form-Dashboard, you could share it as well.

I m a new splunker, thanks again for your time&efforts.

Try getting the value using "mvc.Components.get("sdate").val()". Thus, your code should look something like this:

var unsubmittedTokens = mvc.Components.get('default');
var submittedTokens = mvc.Components.get('submitted');
var urlTokens = mvc.Components.get('url');
var startDate = mvc.Components.get('sdate');
submittedTokens.on('change:startdate', function(){
    // When the token changes...
    if(!submittedTokens.get('startdate')) {
        alert("no token");
    } else {
        alert("got a token");
        var startdate = mvc.Components.get("sdate").val();
        alert(startdate);
    }
});

hey Luke,
I tried this before. I don't know why but got a token alert works. But Val() function doesn't work. that alert is not launched at all. Apparently JS fails to compile at that line. I keep searching, thanks for response.

Did you find a solution to this issue? I am having the same problem getting val() to work.
