changer cursor for whole document javascript

As we’ll see, some of Selection methods imply that there may be many ranges, but again, in all browsers except Firefox, there’s at maximum 1. Other browsers support at maximum 1 range. tEnd(p.querySelector('b').firstChild, 3) P.innerHTML = `Example: italic and bold`

Let newNode = document.createElement('u') Each demonstrated method is represented here: Here’s the test stand to see them in action:Ĭlick buttons to run methods on the selection, 'resetExample' to reset it. With these methods we can do basically anything with selected nodes. For this to work, the range must contain both opening and closing tags for all elements inside it: no partial ranges like abc.

surroundContents(node) – wrap node around range content.

insertNode(node) – insert node into the document at the beginning of the range.

cloneContents() – clone range content and return as DocumentFragment.

extractContents() – remove range content from the document and return as DocumentFragment.

deleteContents() – remove range content from the document.

Once the range is created, we can manipulate its content using these methods:

cloneRange() creates a new range with the same start/end.

collapse(toStart) if toStart=true set end=start, otherwise set start=end, thus collapsing the range.

selectNodeContents(node) set range to select the whole node contents.

selectNode(node) set range to select the whole node.

In all these methods, node can be both a text or element node: for text nodes offset skips that many of characters, while for element nodes that many child nodes. Technically, setStart/setEnd can do anything, but more methods provide more convenience.

setEndAfter(node) set end at: right after node.

setEndBefore(node) set end at: right before node.

setEnd(node, offset) set end at: position offset in node.

setStartAfter(node) set start at: right after node.

setStartBefore(node) set start at: right before node.setStart(node, offset) set start at: position offset in node.We’ve already seen setStart and setEnd, here are other similar methods. There are many convenient methods to manipulate ranges. commonAncestorContainer – the nearest common ancestor of all nodes within the range,.collapsed – boolean, true if the range starts and ends on the same point (so there’s no content inside the range),.in the example above: first text node inside and 3.endContainer, endOffset – node and offset of the end,.in the example above: first text node inside and 2.startContainer, startOffset – node and offset of the start,.
