Hi all,
Few days ago, I have found a solution to obtain the cursor position on a div with contentedit="true"
. I use the solution defined on this web site : Finding cursor position in a contenteditable div
function getCursorPos() {
var cursorPos;
if (window.getSelection) {
var selObj = window.getSelection();
var selRange = selObj.getRangeAt(0);
cursorPos = findNode(selObj.anchorNode.parentNode.childNodes, selObj.anchorNode) + selObj.anchorOffset;
/* FIXME the following works wrong in Opera when the document is longer than 32767 chars */
}
else if (document.selection) {
var range = document.selection.createRange();
var bookmark = range.getBookmark();
/* FIXME the following works wrong when the document is longer than 65535 chars */
cursorPos = bookmark.charCodeAt(2) - 11; /* Undocumented function [3] */
}
return cursorPos;
}
function findNode(list, node) {
for (var i = 0; i < list.length; i++) {
if (list[i] == node) {
return i;
}
}
return -1;
}
It functions well, but when I use html tags inside the div the pointer doesnt show the correct position. For example if I try to find cursor position on the <strong>cat</strong> is black
, the function doesn't return me the good position.
But if I try on the cat is black
, it functions.
Any ideas how to get the position with html tags ?
Thanks for your help.
