[html-formfu] Re $form->get_field with dynamic insert elements

[kewei xiao]

Carl, you were right, the textarea is inserted between existing fields.  
I create a JS function called "loadInfo()" and is called on page load 
event.  In this JS function, first I check whether  the desired radio 
button is checked, if it is.  I will use an Ajax call to get the 
textarea inserted, since I only need to insert once, so I don't think 
DOJO - repeatable will be necessary.

here is the JS function:

function loadInfo(status_id) {
    var info_url = copyrightinfo_url;
    var checkedValue;
    status_element = $(status_id);


    var children = status_element.childNodes;
    for ( var i = 0; i < children.length; i++ ) {
        if ( children[i].nodeType == 3 ) {
            status_element.removeChild(children[i]);
        }
    }

    new Ajax.Request(info_url, {
        method: 'post',
        onSuccess: function(transport) {
            var response = transport.responseText;
            var tmp = document.createElement("div");
            tmp.innerHTML = response; 
            var list = status_element.childNodes;
            for ( var i = 0; i < list.length; i++ ) {
                if (list[i].firstChild.nodeType == 3 ) {
                    list[i].removeChild(list[i].firstChild);
                }
                if ( list[i].firstChild.checked ) {
                    checkedValue = list[i].firstChild.value;
                    if ( checkedValue == 2 && !$("resources") ) {
                        status_element.appendChild(tmp);
                    }                
                    alert($('resource'));
                }
            }
        }
    } ) 
}
--------------------------------------------------------------------------------------------------------------------------------------
info_url will call the resource template to get the textarea create:

<textarea id="resources" name="resources" value="resources" cols=30 
rows=6 onFocus="clearText(this.id)">
Enter resources here
</textarea>

--------------------------------------------------------------------------------------------------------------------------------------
So when page loads up, if the desired radio button is checked, the 
textarea is inserted no problem.  Then I use $form->get_field to get the 
resource textarea, it doesn't recognize.  I wonder if $form->get_field 
works with dynamic insert element.

Thanks for your help
