[Dynapi-Dev] Re: [Dynapi-Help] IO Element again...

[Raymond I. <xw...@ya...>]

Hi Daniel,

Firstly, it's more effecient to create the callback
function on the outside of the PostData() function

var fn = function(e, success) {
	if (!success) alert ('Server Timeout');
}

Secondly, you'll have to loop through all the
checkboxes and then submit their values together:

function GetCheckBoxValues(chk){
	if (!chk.length) {
		if(chk.checked) return chk.value;
	}else {
		var i,ar=[];
		for(i=0;i<chk.length;i++) {
			if(chk[i].checked) ar[ar.length]=chk[i].value;
		};	
		return ar.join(',');
	}
};

You can see the util/datasource.js file (lines
368-445) for other examples.

And finally here's what the PostData() function would
look like:

function PostData(formName) {
	var elm,f = eval('document.forms.'+formName);
	var data = {}
	for(var i=0;i<=f.elements.length;i++){
		elm = f.elements[i];
		if (elm != null) {
		if (elm.type == 'text') {
			data[elm.name]=elm.value;
			alert(elm.name+':'+elm.value+':'+elm.type);
		}
		else if (elm.type == 'radio') {
			if (elm.checked) {
				data[elm.name]=elm.value;
				alert(elm.name+':'+elm.value+':'+elm.type);
			}
		}
		else if (elm.type == 'checkbox') {
			var vl = GetCheckBoxValues(elm);
			if(vl){
				data[elm.name] = vl;
				alert(elm.name+':'+vl+':'+elm.type);
			}
		}
	}
	ioelement.post('/admin/login.asp?action=PostAddUser',
data, fn);
}
