Question

我想访问HTML所选区域中的所有节点。

path:some-file-name

之后怎么办？

Answer 1

你可以这样做：

var sel = window.getSelection();
sel.toString()

获取选择的内容

查看另一篇使用onMousUp事件的帖子，了解选择结束的元素： How can I get the DOM element which contains the current selection?

function getSelectionBoundaryElement(isStart) {
    var range, sel, container;
    if (document.selection) {
        range = document.selection.createRange();
        range.collapse(isStart);
        return range.parentElement();
    } else {
        sel = window.getSelection();
        if (sel.getRangeAt) {
            if (sel.rangeCount > 0) {
                range = sel.getRangeAt(0);
            }
        } else {
            // Old WebKit
            range = document.createRange();
            range.setStart(sel.anchorNode, sel.anchorOffset);
            range.setEnd(sel.focusNode, sel.focusOffset);

            // Handle the case when the selection was selected backwards (from the end to the start in the document)
            if (range.collapsed !== sel.isCollapsed) {
                range.setStart(sel.focusNode, sel.focusOffset);
                range.setEnd(sel.anchorNode, sel.anchorOffset);
            }
       }

        if (range) {
           container = range[isStart ? "startContainer" : "endContainer"];

           // Check if the container is a text node and return its parent if so
           return container.nodeType === 3 ? container.parentNode : container;
        }   
    }
}
