hello i've got a small problem with the data object. i always get the dragged text with "undefined" at the end. why?

source frame:
<html>
<head>
<title>netBox</title>
<link rel="STYLESHEET" type="text/css" href="include/main.css">
<script>
ns4 = (document.layers)? true:false;
ie4 = (document.all)? true:false;
var tempX = 0
var tempY = 0
function getY(e) {
if (ie4) {
tempY = event.clientY + document.body.scrollTop
} else {
tempY = e.pageY
}

if (tempY < 0){tempY = 0}
return tempY-5;
}
function getX(e) {
if (ie4) {
tempX = event.clientX + document.body.scrollTop
} else {
tempX = e.pageX
}

if (tempX < 0){tempX = 0}
return tempX-180;
}
if (!ie4) document.captureEvents(Event.MOUSEMOVE)

function setStyleByTag(e, p, v, g) {
if(g) {
var elements = document.getElementById(e);
elements.style['top'] = p;
elements.style['left'] = v;
} else {
var sheets = document.styleSheets;
if(sheets.length > 0) {
for(var i = 0; i < sheets.length; i++) {
var rules = sheets.cssRules;
if(rules.length > 0) {
for(var j = 0; j < rules.length; j++) {
var s = rules[j].style;
ugly_selectorText_workaround();
if(allStyleRules) {
if(allStyleRules[j] == e) {
s['top'] = p;
s['left'] = v;
}
} else {
if(((s[p] != "") && (s[p] != null)) && (rules[j].selectorText == e)) {
s['top'] = p;
s['left'] = v;
}
}
}
}
}
}
}
}
function hide(id) {
if (ns4) document.layers[id].visibility = "hide";
else if (ie4) document.all[id].style.visibility = "hidden";
}
function show(id) {
setStyleByTag(id,getY(),getX(),1);
if (ns4) document.layers[id].visibility = "show";
else if (ie4) document.all[id].style.visibility = "visible";
}

Where is the dragged text? Where are you dragging it to? Is the missing CSS neeed to help debug this issue?

Help us out a bit here!

i forgot to post the parent frame with the drag functions:

function handleMouseMove(tmp) {
if (window.parent.tree.event.button == 1) {
eval('parent.tree.document.all.divDrag' + tmp + '.dragDrop()');
}
}
function handleDragStart(tmp,tmp2) {
eval('window.parent.tree.event.dataTransfer.setData("text", "' + tmp + tmp2 + '")');
}


the drag text is: 4§elektro.cad
and it is triggerd by following command in the source frame: ondragstart="parent.handleDragStart('4§elektro.cad')"

I reconstructed frameset somehow and now script complains that tree.event doesn't exist. :E

What is strange about these functions: they are called through parent and eval() parent. How many nested frames you have?

Also, source frame contains NS/IE branches... while handleMouseMove() uses document.all (non-compliant way to access DOM element).

hi there,

the easiest way is to go to user:test pwd:test

here you can browse through the left tree and drag the element test_elektro.cad to one of the right frames

Just tested in IE6 - drag&drop works OK to both download/upload frames. No error messages, no "undefined" text labels. (?!?)

Mozilla says "Error: window.parent.tree.event has no properties (Line: 58)" when I mouse over text_elektro.cad.

sorry, that file done yesterday but not anymore, but the file "afg 1.2.1.cad" in "test1.2" still does it
