How do I find out the DOM node when select text in a browser’s editable content window using Javascript?

Question

I want to get parentElement when I select some text in iframe.

iframe = document.getElementById("iframe");
function getParentElement(){
 var sel=iframe.contentDocument.getselection();
 return sel.parentElement()
}
getParentElement();

when I run this code it show Error:" TypeError: iframe.contentDocument.getSelection().parentElement is not a function { message="iframe.contentDocument....ement is not a function", more...}"

Please give me a help!

Answer 1

Selection object (returned by getSelection()) has no method named parentElement(). This will give you the parent:

getSelection().anchorNode.parentNode

See Mozilla's DOM reference.
