我如何能够让泽德·Decorator允许设定违约价值?
原标题:How can I make a Zend Decorator to allow a default value?
最佳回答

Ok, I ve built a decorator which allows me to implement the jquery plugin Ololo posted. It checks to see if the element has a Label set, and if it does, defaults to that:

require_once  Zend/Form/Decorator/Abstract.php ;

class Application_Form_Decorator_DefaultEnabledInput extends Zend_Form_Decorator_Abstract
{
    private $attribs = array();
    public function render($content)
    {
        $element = $this->getElement();

        if(get_class($element) !=  Zend_Form_Element_Text ) throw new Exception("Application_Form_Decorator_DefaultEnabledInput only works on text fields");

        $element->setAttrib( type ,  text );
        $element->setAttrib( name , htmlspecialchars($element->getName()));
        $element->setAttrib( value , htmlspecialchars($element->getValue()));

        $attribs =   ;
        $default = $element->getLabel();
        if($default)
        {
            $element->setAttrib( rel , $default);
            $element->setAttrib( title , $default);
            $class = $element->getAttrib( class );
            $element->setAttrib( class , "$class hasDefault");
            $default = "";
        }
        foreach($element->getAttribs() as $key => $val) $attribs .= "$key= $val  ";
        return "<input $attribs/>";
    }
}

这使我能够用标语界定违约值(使用套工)。

    $element = $this->createElement( text ,  suburb );
    $element->setDecorators(array( DefaultEnabledInput ));
    $element->setLabel( enter suburb here );
    $this->addElement($element); 

因此,我需要做的是确保将问询和假想列入网页,这部法典:

$(document).ready(function() {
    // default values
    $( .hasDefault ).each(function(){
        $(this).defaultValue();
    });
});

然后,在模板中,我可以展示这样的目标:

<?= $this->form->getElement( suburb ) ?>

正当使用 j Query plugins: default Value
