have this html:
<div id="editable" contentEditable="true" >
<span contentEditable="false" >Text to delete</span>
</div>
need that the span (and all text inside) is removed with a single backspace, is it possible?
This turned out to be more complicated than I thought. Or I've made it more complicated than it needs to be. Anyway, this should work in all the big browsers:
function getLastTextNodeIn(node) {
while (node) {
if (node.nodeType == 3) {
return node;
} else {
node = node.lastChild;
}
}
}
function isRangeAfterNode(range, node) {
var nodeRange, lastTextNode;
if (range.compareBoundaryPoints) {
nodeRange = document.createRange();
lastTextNode = getLastTextNodeIn(node);
nodeRange.selectNodeContents(lastTextNode);
nodeRange.collapse(false);
return range.compareBoundaryPoints(range.START_TO_END, nodeRange) > -1;
} else if (range.compareEndPoints) {
if (node.nodeType == 1) {
nodeRange = document.body.createTextRange();
nodeRange.moveToElementText(node);
nodeRange.collapse(false);
return range.compareEndPoints("StartToEnd", nodeRange) > -1;
} else {
return false;
}
}
}
document.getElementById("editable").onkeydown = function(evt) {
var sel, range, node, nodeToDelete, nextNode, nodeRange;
evt = evt || window.event;
if (evt.keyCode == 8) {
// Get the DOM node containing the start of the selection
if (window.getSelection && window.getSelection().getRangeAt) {
range = window.getSelection().getRangeAt(0);
} else if (document.selection && document.selection.createRange) {
range = document.selection.createRange();
}
if (range) {
node = this.lastChild;
while (node) {
if ( isRangeAfterNode(range, node) ) {
nodeToDelete = node;
break;
} else {
node = node.previousSibling;
}
}
if (nodeToDelete) {
this.removeChild(nodeToDelete);
}
}
return false;
}
};
