javascript - 从数组中删除元素并将其移动到另一个

Question

我必须随机生成测验，答案是 3 个随机名称，其中 1 个是正确的，我已经完成了随机化和洗牌，但我必须在显示的元素出现时将其从数组中取出，以便它当我单击下一步时，它不会被随机化并再次选择，当我单击下一步时，它会显示下一个随机化的东西，但目前它不会切换它。有人可以帮忙吗？

var receivedArray   = JSON.parse(0: {nameIMGTOP: "-5", nameIMGTOPafter: "-10", nameIMGLEFT: "18", nameIMGLEFTafter: "22", nameTOP: "-3"}
1: {nameIMGTOP: "13", nameIMGTOPafter: "11", nameIMGLEFT: "27", nameIMGLEFTafter: "11", nameTOP: "32"}
2: {nameIMGTOP: "-6", nameIMGTOPafter: "", nameIMGLEFT: "36", nameIMGLEFTafter: "", nameTOP: "-3"}
3: {nameIMGTOP: "16", nameIMGTOPafter: "", nameIMGLEFT: "55", nameIMGLEFTafter: "", nameTOP: "18"}
4: {nameIMGTOP: "13", nameIMGTOPafter: "", nameIMGLEFT: "73", nameIMGLEFTafter: "", nameTOP: "37"});
    console.log(receivedArray);
    const StartElements = receivedArray;
    const correctAnswer = StartElements.splice(Math.floor(Math.random() * StartElements.length), 1)[0];
    const guess1        = StartElements.splice(Math.floor(Math.random() * StartElements.length), 1)[0];
    const guess2        = StartElements.splice(Math.floor(Math.random() * StartElements.length), 1)[0];
    //array with few elements and variables for randomizing different things from the array
    
    function move() {
        array = new Array([]);
          while(correctAnswer !== 1){
            correctAnswer.splice();
            array.push(correctAnswer);
            console.log(array);
          }
    }
    //I've tried many different things and I can't get it down
    
    //Everything displays in Jquery made HTML
    $("#test-div").append(
            "<div class=\"row\">\n"+
            "<div class=\"col-6\">\n" +
            "<div class=\"ImageDiv\">" +
            "<img id=\"testImage\" src=\"\" alt='...' align=\"middle\"/>\n" +
            "</div>" +
            "</div>\n" +
            "<h4 class=\"Guess\" id=\"Guess\">ATMINI JŪRNIEKU MEZGLA NOSAUKUMU</h4>\n"+
            "<p id=\"description\"></p>"+
            "<div class=\"col-6 shuffle\">\n" +
            "<div class=\"btn guesses\" >"+correctAnswer.nameLV+"</div><br>"+
            "<div class=\"btn guesses\" >"+guess1.nameLV+"</div><br>"+
            "<div class=\"btn guesses\" >"+guess2.nameLV+"</div><br>"+
            "</div>\n" +
            "</div>\n"
            );

正如我在评论中所说，很难弄清楚你想要做什么，但如果这只是“删除特定项目”的问题，那么使用 Array.filter是一种很好且简单的方法:

const startArray = [{0: 'item 0'}, {1: 'item 1'}, {2: 'item 2'}, {3: 'item 3'}]

const elementToRemove = startArray[1] // or whichever item you want

const newArray = startArray.filter(item => item !== elementToRemove)

console.log(newArray)

// =>  [{0: 'item 0'}, {2: 'item 2'}, {2: 'item 3'}]
