I want to wrap a selected text in a div container with span, is it possible?
A user will select a text and will click a button, on button click event I want to wrap that selected text with span element. I can get the selected text using window.getSelection()
but how to know its exact position in DOM structure?
If the selection is completely contained within a single text node, you can do this using the surroundContents()
method of the range you obtain from the selection. However, this is very brittle: it does not work if the selection cannot logically be surrounded in a single element (generally, if the range crosses node boundaries, although this is not the precise definition). To do this in the general case, you need a more complicated approach.
Also, DOM Range
and window.getSelection()
are not supported in IE < 9. You'll need another approach again for those browsers. You can use a library such as my own Rangy to normalize browser behaviour and you may find the class applier module useful for this question.
Simple surroundContents()
example jsFiddle: http://jsfiddle.net/VRcvn/
Code:
function surroundSelection(element) {
if (window.getSelection) {
var sel = window.getSelection();
if (sel.rangeCount) {
var range = sel.getRangeAt(0).cloneRange();
range.surroundContents(element);
sel.removeAllRanges();
sel.addRange(range);
}
}
}
