parent(cssSelector)

Selector().parent(cssSelector) → Selector

Looks for parent elements that match the CSS Selector parameter.

Argument	Type	Description
cssSelector	String	CSS Selector.

parent(filterFn, dependencies)

Selector().parent(filterFn [, dependencies]) → Selector

Filters parent elements with a function.

Argument	Type	Description
filterFn	Function	Filter function.
dependencies (optional)	Object	Functions, variables, or objects passed to the filterFn function.

See Filter DOM With A Function.

Examples

// Selects all ancestors of all div elements.
const divParents = Selector('div').parent();

// Selects all closest parents of all input elements.
const inputClosestParents = Selector('input').parent(0);

// Selects all furthest ancestors of all labels.
const columnFurthestParents = Selector('label').parent(-1);

// Selects all divs that are ancestors of an 'fieldset' element.
const fieldsetDivParents = Selector('fieldset').parent('div');

Filter DOM with a function

To filter the DOM with a client-side filter function, pass a function argument to the method.

The filterFn argument accepts the following parameters:

Parameter	Description
node	The current node.
idx	The index of the current node.
originNode	The DOM Node .

Selector('section').prevSibling((node, idx, originNode) => {
    // node === the <section>'s preceding sibling node
    // idx === index of the current <section>'s preceding sibling node
    // originNode === the <section> element
});

Use the dependencies option to pass variables to the filter function.

const isNodeOk = (node, idx, originNode) => {
    console.log({ node, idx, originNode });
    return idx === 6;
};

const filteredDiv = Selector('div').prevSibling((node) => {
    return !isNaN(node.textContent);
}, { isNodeOk });
