Selection
This module provides several helpful methods working with browser selection.
findParentTag — looks ahead from selection and finds passed tag with class name
expandToTag — expands selection to the passed tag
Finds parent tag with passed class name
| String | tag's name that will be found |
| String | tag's class name must match this argument |
?HTMLElement
|
found HTML element or null if not found |
findParentTag(tagName: string, className?: string): HTMLElement|null
class MyInlineTool {
constructor({api}) {
this.api = api;
}
surround(range) {
if (range) {
const parentAnchor = this.selection.findParentTag('A');
if (parentAnchor) {
// found closest 'A' tag that wraps current selection
// do something
}
}
}
}
Wraps current selection with passed tag
HTMLElement
|
HTML element that will wrap the selection |
Method does not return anything
expandToTag(node: HTMLElement): void
class MyInlineTool {
constructor({api}) {
this.api = api;
}
surround(range) {
if (range) {
const parentAnchor = this.api.selection.findParentTag('A');
if (parentAnchor) {
// found closest 'A' tag that wraps current selection
this.api.selection.expandToTag(parentAnchor);
}
}
}
}
