创建一个复选框类型 li 然后循环整个事情 3 次

Question

所以我想做三件事： 1- 为 class 成分的 li 创建复选框。 2-删除在 li 类指令之后添加的讨厌的 li。 3- 将整个过程循环 3 次，这样我就有了 3 个食谱容器，只是食谱的图像不同 class。

var main = function () {

    var $checkBoxes = document.createElement('div');
         $checkBoxes.setAttribute("class", "checkBoxes");
    var $recipePicContainer =  document.createElement('span');
         $recipePicContainer.setAttribute("class", "recipePicContainer");


    function makeRecipePic(){
        var recipe = document.createElement("IMG");
            recipe.setAttribute("src", "../images/grasshopper-cocktail.jpg");
            recipe.setAttribute("class", "recipe");
            $recipePicContainer.appendChild(recipe);

    }
    makeRecipePic();

    var mainContainer = document.getElementsByClassName('mainContainer');
        mainContainer[0].appendChild($checkBoxes);

    var $div = document.createElement('div');
        $div.innerHTML = 'CockTails';
        $recipePicContainer.appendChild($div);
        $checkBoxes.appendChild($recipePicContainer);


    var $recipes = document.createElement("ul");
    var $checkboxes = document.getElementsByClassName('checkBoxes');

    //var x = document.createElement("INPUT");
    //x.setAttribute("type", "checkbox");

    for (var i = 1; i <= 6; i++) {
        var li = document.createElement("li","INPUT");
        li.className = "ingredients";
        li.setAttribute("type", "checkbox");

        var a = document.createElement("a");
        a.innerHTML = "Ingredient " + i;

        li.appendChild(a);
        $recipes.appendChild(li);
    }
    var b = document.createElement("li");
    li.innerHTML = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
    li.className = "Instructions";
    li.appendChild(b);

    $checkboxes[0].appendChild($recipes);
    $('.recipes').hide();

    $('.mainContainer .recipePicContainer').click(function () {
        $(this).next('ul').toggle("slow").toggleClass('selected');

    });
};
$(document).ready(main);

Answer 1

第二步：li.appendChild(b); 将摆脱多余的讨厌的 li 。
