How to get sum of pushed array
本问题已经有最佳答案,请猛点这里访问。
有人能帮我把被推的数字和到数组中吗?我需要在20回合后显示总数。我按记分单,这是由球员键入,所有的分数需要乘以20轮后才能看到结果。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | var round = 1; var score1 = []; function roundNr() { round++; document.getElementById("p").innerHTML = round; } function scoreCntr() { var scorePoint1 = document.getElementById('score1').value; score1.push(scorePoint1); if (round > 20) { document.getElementById("score").innerHTML = score1; } } |
1 2 3 4 5 6 7 8 9 | <input type="name" placeholder="Name" id="name1"> <input type="text" placeholder="Score" id="score1"> <button onclick="roundNr(); scoreCntr();">Submit</button> ROUND <p id="p">1 </p> |

在计算总和的
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | var round = 1; var score1 = []; function roundNr() { round++; document.getElementById("p").innerHTML = round; } function scoreCntr() { var scorePoint1 = document.getElementById('score1').value; score1.push(scorePoint1); if (round > 20) { var sum = 0; score1.forEach(val=>sum+=parseInt(val)); document.getElementById("score").innerHTML = sum; } } |
1 2 3 4 5 6 7 8 9 | <input type="name" placeholder="Name" id="name1"> <input type="text" placeholder="Score" id="score1"> <button onclick="roundNr(); scoreCntr();">Submit</button> ROUND <p id="p">1 </p> |
