trap paste command --urgent

Reply Quote

Hi Adam,

The requirement is something like when user click on the paste button and try to paste some content which contains some string say "Position:absolute" then need to prompt some message saying the "this containspositionas absolute".

Now for this I can trap the Paste command with

CuteEditor_OnCommand(editor,command,ui,value).

but how to get the content which user is about to paste.

in above on debug I found value and ui is comming as null

I'm using followin code to trap the command.

var editor1=document.getElementById("<%=Editor1.ClientID%>");

if(editor1.IsReady)CuteEditor_OnInitialized(editor);

function CuteEditor_OnCommand(editor,command,ui,value)

{

//handle the command by yourself

if(command=="Paste")

{

//Some code--- IsContainsAbsoluteposition(Contentstring)???? how to get this Contentstring

var answer = confirm("Click OK to stop this command.")

if (answer){

return true;

}

else{

return false;

}

</script>

Thanks

Hi adam,

I think you have not read properly what I've asked for.

also the link you are refering is having same code that I've mentioned in my query.

The thing I 'm asking for is

1. a way to get the HTML content which is about to be pasted? might be in clipboard or some where else.

2. how cute editor use these paste commands. means from where it gets the value(HTML content) to be pasted on editor?

function getSelectedHTML(){
var rng=null,html="";

      if (document.selection && document.selection.createRange){
        rng=editdoc.selection.createRange();
        html=rng.htmlText||"";
      }else if (window.getSelection){
        rng=editwin.getSelection();

        if (rng.rangeCount > 0 && window.XMLSerializer){
          rng=rng.getRangeAt(0);
          html=new XMLSerializer().serializeToString(rng.cloneContents());
        }
      }
      return html;
    }

You can use the above code to get the html code from the current selection or you can write your own.

Hi,

When clicked on paste button,I want to check whether the HTML content that is about to paste contains some tags like "position:absolute". if yes then will discard past else allow paste.

and to acheive this I amusing JS code as I pasted above in this thread itself. again I'm pasting it here.

var editor1=document.getElementById("<%=Editor1.ClientID%>");

if(editor1.IsReady)CuteEditor_OnInitialized(editor);

function CuteEditor_OnCommand(editor,command,ui,value)

{ //handle the command by yourself

if(command=="Paste")

{

//Some code--- IsContainsAbsoluteposition(Contentstring)???? how to

get this Contentstring

var answer = confirm("Click OK to stop this command.")

if (answer)

{

return true;

}

else{return false;}

}

</script>

this code is to trap the paste command which is working, but how to get the HTML content which is about to paste? so that I can check the content before it gets pasted on editor.

Hopefully now you guys understand what I'm asking for.

Do you have any chat/phone support for "cuteEditor for ASP.Net"? if yes please provide the details.

Thanks.

Hi,

you need create that element at first.

for example:

var element=document.createElement("DIV");

element.style.position="absolute";

element.style.overflow="hidden";

element.style.width="1px";

element.style.height="1px";

document.body.appendChild(element);

var r = document.body.createTextRange() ;
r.moveToElementText(element) ;
r.execCommand("Paste") ;
sHTML = element.innerHTML ;
alert(sHTML);

Note: this is IE only. other browsers have difference API for the TextRange

Regards,

Terry
