Update page dynamically ?


Recommended Posts

Hello & Thanks; 

I am making great progress on my project , thanks to you folks .

But I do still have a problem with  'createElement' and 'appendChild' . 

They work fine but when I try to Drag the 'newly created div' it doesn't drag .

If I saveAs the page and open the saved page , The created 'div' Drag works fine . 

So it seems that something is not getting updated dynamically .

Pls , why does this happen , and how to fix it ?

First, instead of setAttribute("draggable"  ) you should set the draggable property of the element, as element.draggable = true.

Once the element has been created, you have to call the dragElement() function to add the event listeners to this element. Without the event listeners the element cannot be draggable.

Thanks Ingolme


Works great .

I have another problem , same program: 

in here:

var copyFromVar = "one"; 
function saveItAll() {
alert("Hello  from  function saveItAll()");
console.log("Hello  from  function saveItAll()");
var blankVar = "";
var  fromList   = document.getElementsByClassName("copyFrom");
var  intoList    = document.getElementsByClassName("pasteInto");
alert("fromList.length = " + fromList.length);

  for (var i = 0; i < fromList.length; i++) {
alert("for (var i = 0; i < fromList.length; i++)");
console.log("fromList.length = " + fromList.length);
    copyFromVar = fromList[i].value ;
console.log("copyFromVar = " + copyFromVar);
    intoList[i].innerHTML   = copyFromVar;
console.log("intoList[i].innerHTML = " + intoList[i].innerHTML);
} //

None of the console.log() statements work .

And the second alert() doesn't work .

Any idea why nothing works beyond the 1st alert() ? 


I'll Post the whole code if you wish .
