cheerio-eq

Add :eq() selector functionality to cheerio.

If you are looking for a more advanced solution with support for multiple advanved selectors, check out the cheerio-advanced-selectors module.

What's the problem?

Cheerio sacrifices advanced CSS selector support for speed. This means for instance that the :eq() selector isn't supported. The work-around is normally to use the .eq() function instead:

// this will not work:
$('div:eq(1)');

// use this instead:
$('div').eq(1);

This is a good alternative if you write the CSS selectors from scrach, but what if you are working with selectors that already contain :eq()? Don't fear, cheerio-eq is here :)

Solution

The solution to the problem is to automatically parse the selector string at run-time. So if you give cheerio-eq a selector like div:eq(1) it will return the following cheerio cursor: $('div').eq(1).

It also works for complex selectors, so that div:eq(1) h2:eq(0) span will be converted and interpreted as $('div').eq(1).find('h2').eq(0).find('span').

Installation

npm install cheerio-eq

Usage

var cheerio = require('cheerio');
var find = require('cheerio-eq');

var html = '<div>foo</div><div>bar</div>';
var selector = 'div:eq(1)';

var $ = cheerio.load(html);

console.log(find($, selector).text()); // => 'bar'

API

The cheerio-eq module exposes a single function, which takes 2 arguments:

• The cheerio DOM object (usually just named $)
• A string containing the selector to parse
