text passing

I use javascript to build a string. Now I want to take that string and go to the controller and do something with it. Can someone walk me through how I would take a variable from my view and access it in the controller when I hit a submit button?

Can you please provide more details on your problem, maybe some code snippets… I didn’t get anything

So I have javascript functions that builds a string (textarea rows="3" cols="110" id="plinkTextBox"). I want to take that text area and when I click submit i want to be able to go to my controll file and grab the text inside plinkTextBox. How do I do that?

<script type="text/javascript">

(function ()

{

    window.onerror = function myErrorHandler(errorMsg, url, lineNumber) {

        alert(errorMsg+" "+lineNumber);

        return true;

    }

})();


</script>

<script type="text/javascript" >


<!--

function HideList() 

{

  var status = document.getElementById('cbChoices').checked;

  if (status == false) { document.getElementById('ScrollCB').style.display = "block"; }

                 else { document.getElementById('ScrollCB').style.display = 'none'; }

}


function showEmail()

{

	var status = document.getElementById('emailChoose').checked;

	if (status == false) { document.getElementById('emailAddress').style.display = "none"; }

		else { document.getElementById('emailAddress').style.display = 'block'; }

}

-->

</script>


<?php  

  $baseUrl = Yii::app()->baseUrl; 

  $cs = Yii::app()->getClientScript();

  $cs->registerScriptFile($baseUrl.'/js/plinkbuilder.js');

First, your textarea must be inside a form.

Second, form’s action must point to a controller/action.

Third, you should read the guide
