Soit le retour de la sélection rend compte des limites de mots : pas du tout

Le résultat de la sélection correspond à une séquence d'occurences de mots projetée sur une propriété : word - qui correspond à la surface sélectionnée modulo recalage.

note: works only if anchor node preceeds focus node
SH: Could use Node.compareDocumentPosition() to decide how to move in the DOM ('next|previous'Sibling). See https://groupes.renater.fr/wiki/txm-info/documentation_web.

JS code to get selection content (FF, IE11+, Safari)

    var all = "" 
    var sel = window.getSelection();
    var node = sel.anchorNode.parentNode;
    while (node != sel.focusNode.parentNode) {
        all += node.textContent
        node = node.nextSibling;
    }

    all += sel.focusNode.parentNode.textContent
    alert(all);

JS code to retrive id from selected span

function getID(node) {
    if (node.nodeType == 1) {

        for (i = 0; i < node.attributes.length; i++) {
            if (node.attributes[i].name == "id") {
                return node.attributes[i].value;
            }
        }
    }

    return "" 
}

function myFunction() {
    var all = []
    var sel = window.getSelection();
    var node = sel.anchorNode.parentNode;
    while (node != sel.focusNode.parentNode) {
        all.push(getID(node))
        node = node.nextSibling;
    }

    all += getID(sel.focusNode.parentNode)
    alert(all);
}

Solution¶

Previous solutions don't manage word half selected.
The solution is to use the first Range (https://developer.mozilla.org/en-US/docs/Web/API/Range) of the Selection (https://developer.mozilla.org/en-US/docs/Web/API/Selection) to get the id of the first word span and the id of the last word span. Then resolve the CQP "word" properties of positions between pos(START_SPAN_WORD_ID) and pos(END_SPAN_WORD_ID)

function findSpans(c, a) {
    for (var i = 0 ; i < c.length ; i++) {
        if (c.item(i).tagName == "SPAN") {
            var id = c.item(i).getAttribute("id")
            if (id.indexOf("w_") == 0)
                a.push(id)
        } else if (c.item(i).nodeType == 1) {
            findSpans(c.item(i).children, a)
        }
    }
}
function getWordIDFromSelection() {
    var all = [];
    var sel = window.getSelection();
    if (sel.rangeCount == 0){
        return all;
    }

    var range = sel.getRangeAt(0);
    var frag = range.cloneContents();
    findSpans(frag.children, all);
    return all
}
