Delphi for PHP 설치폴더에서 vcl/js/common.js 를 연다.

파일 제일 하단에 아래의 코드 추가

 vcl=

var elements = new Array();
for (var i = 0; i < arguments.length; i++)
{
var element = arguments[i];
if (typeof element == 'string')

elements.push(element);
}

return elements;

theObj.style.opacity = value/10;
theObj.style.filter = 'alpha(opacity=' + value*10 + ')';
}
}

{
if (xmlHttp.status == 200)

}
}
}

if (typeof(basicAjaxAsyncFalse) != 'undefined' && basicAjaxAsyncFalse==1) xmlHttp.open("POST",url,false); //this will force a wait for return
xmlHttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xmlHttp.setRequestHeader("If-Modified-Since", "Fri, 31 Dec 1999 23:59:59GMT");

}

Basic Ajax사용법

  //call basicAjax but override the eval function
basicAjax("ajax_server.php","value1=Bob",myfunction);

//call basicAjax using the built in eval function
var params='value1='+vcl.$('Edit1').value+'&value2='+vcl.$('Edit2').value;
basicAjax("ajax_server1.php",params);

vcl.$() 사용법

 // Sample Usage:
               function Button2JSClick($sender, $params)
               {

               ?>
alert(vcl.$('Edit1').value);//just get one object

//these 3 are identical
var obj1 = document.getElementById('Edit1');
var obj2 = vcl.$('Edit1');
var obj3= FindObj('edit1');

 vcl.$('Edit1').disabled;

//this gets an array of objects!! (includes obj we all ready had found also
// and real objects like LabeledEdit)
var elements = vcl.$('Edit2','Edit4','Edit6',obj1,obj2,'Edit5','Edit3');
for (var i=0;i < elements.length; i++) elements[i].value='';
//we just blew through a bunch of edits and cleared them.
// fyi this wouldn't work this way with the labeled edits though - they need setValue('')
               <?php

               }

 

 // Sample Usage:
vcl.hide('Button1');
vcl.show('Button1');
