Cookpadで材料を指定するもメニューが多すぎて選びきれないときに勝手に選んでくれるやつ

cookpad.js

function parseQuery(query) {
    var result = {};
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        result[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1]);
    }
    return result;
}

var params = parseQuery(__load_parameters);
var selected = ~~(Math.random() * params.rh);
$.get(`${location.origin + location.pathname}?page=${selected/10}&recipe_hit=${params.rh}`, function(data){
    var div = document.createElement("div");
    div.innerHTML = data
    div.getElementsByClassName("recipe-title font13")[selected % 10].click();
});
