You can’t set manually name property for form data like- input, buttons and all things. if your set manually then your save function doesn’t recognize the form post data in your action controller.

CActiveForm::textField automatically generates the ‘name’ property for you that is compatible with the way the controller receives the input values from $_POST. The generated ‘name’ property is usually in the form of ‘ModelName[attribute_name]’ … check the HTML generated by Yii.

But I would recommend you to use CHtml::activeName to get the name, because it is the method that CActiveForm::textField uses to generate the name.

var num1 = parseInt(document.getElementByName('<?php echo CHtml::activeName($model, 'val1'); ?>').value);
