Remove All Nodes with (nodeName = "script") from a Document Fragment *before placing it in dom*
- by Matrym
My goal is to remove all <[script] nodes from a document fragment (leaving the rest of the fragment intact) before inserting the fragment into the dom.
My fragment is created by and looks something like this:
range = document.createRange();
range.selectNode(document.getElementsByTagName("body").item(0));
documentFragment = range.cloneContents();
sasDom.insertBefore(documentFragment, credit);
document.body.appendChild(documentFragment);
I got good range walker suggestions in a separate post, but realized I asked the wrong question. I got an answer about ranges, but what I meant to ask about was a document fragment (or perhaps there's a way to set a range of the fragment? hrmmm). The walker provided was:
function actOnElementsInRange(range, func) {
function isContainedInRange(el, range) {
var elRange = range.cloneRange();
elRange.selectNode(el);
return range.compareBoundaryPoints(Range.START_TO_START, elRange) <= 0
&& range.compareBoundaryPoints(Range.END_TO_END, elRange) >= 0;
}
var rangeStartElement = range.startContainer;
if (rangeStartElement.nodeType == 3) {
rangeStartElement = rangeStartElement.parentNode;
}
var rangeEndElement = range.endContainer;
if (rangeEndElement.nodeType == 3) {
rangeEndElement = rangeEndElement.parentNode;
}
var isInRange = function(el) {
return (el === rangeStartElement || el === rangeEndElement ||
isContainedInRange(el, range))
? NodeFilter.FILTER_ACCEPT : NodeFilter.FILTER_SKIP;
};
var container = range.commonAncestorContainer;
if (container.nodeType != 1) {
container = container.parentNode;
}
var walker = document.createTreeWalker(document,
NodeFilter.SHOW_ELEMENT, isInRange, false);
while (walker.nextNode()) {
func(walker.currentNode);
}
}
actOnElementsInRange(range, function(el) {
el.removeAttribute("id");
});
That walker code is lifted from: http://stackoverflow.com/questions/2690122/remove-all-id-attributes-from-nodes-in-a-range-of-fragment
PLEASE No libraries (ie jQuery). I want to do this the raw way. Thanks in advance for your help
