javascript - 对整数数组进行排序并在输入上显示值

Question

我有一个包含很多输入字段的网站，我想对其中的数据进行排序。

如您所见，我想对总分列进行排序，并将位置放在 MVP 输入字段中。为此，我想使用 javascript 函数.sort();。

function sortmvp() {
    var mvp = new Array();
    mvp[0] = parseInt(document.getElementById('p1_5h').value);
    mvp[1] = parseInt(document.getElementById('p2_5h').value);
    mvp[2] = parseInt(document.getElementById('p3_5h').value);
    mvp[3] = parseInt(document.getElementById('p4_5h').value);
    mvp[4] = parseInt(document.getElementById('p5_5h').value);
    mvp[5] = parseInt(document.getElementById('p6_5h').value);

    mvp.sort();
}

那些p1_5h, p2_5h, p1_5h... 是Total列的输入。此时我只对数组上的数据进行了排序，但我必须显示它们。

问题是我不知道如何在正确的输入中显示正确的位置（1,2,3,4...），如上图所示。有什么建议吗？

Javascript

function calc() {
    var h1 = parseInt(document.getElementById('h1').value);
    var h2 = parseInt(document.getElementById('h2').value);
    var h3 = parseInt(document.getElementById('h3').value);
    var o1 = parseInt(document.getElementById('o1').value);
    var o2 = parseInt(document.getElementById('o2').value);
    var o3 = parseInt(document.getElementById('o3').value);

    var toth = h1 + h2 + h3;
    var toto = o1 + o2 + o3;

    document.getElementById('htot').value = toth;
    document.getElementById('otot').value = toto;


    document.getElementById('diff1').value = h1 - o1;
    document.getElementById('diff2').value = h2 - o2;
    document.getElementById('diff3').value = h3 - o3;
    document.getElementById('difftot').value = toth - toto;

    htot = document.getElementById('htot');
    otot = document.getElementById('otot');

    if (htot.value == otot.value) {
        htot.style.color = 'blue';
        otot.style.color = 'blue';
    } else {
        if (htot.value > otot.value) {

    var totals = [],

    for (var i = 0, i < 6; i++) {
        totals[i] = parseInt(document.getElementById('p' + (i + 1) + '_5h').value, 10);
        indices[i] = i;

    for (var i = 0; i < indices.length; i++)

}

Answer 1

实际上，您不想对总值进行排序，而是按各自的值对它们的索引进行排序。这样你仍然知道哪个索引属于哪个字段。

var totals = [],
    indices = [];
for (var i=0; i<6; i++) {
    totals[i] = parseInt(document.getElementById('p'+(i+1)+'_5h').value, 10);
    indices[i] = i;
}
indices.sort(function(a, b) {
    return totals[a] - totals[b];
});
for (var i=0; i<indices.length; i++)
    document.getElementById('mvp'+(indices[i]+1)).value = (i+1);

Answer 2

好的，与@Bergi 接受的答案相同的原则我拿走了你的 jsfiddle 并清理了它（删除了内联 Javascript 和 CSS），希望它会给你更多的想法，并提出了以下工作示例。

CSS

fieldset.a {
    width: 90%;
}
fieldset.a legend {
    font-weight: bold;
}
fieldset.a > div:nth-of-type(1) {
    height: 240px;
    width: 100%;
    overflow-y: scroll;
    border :1px solid #D8D8D8;
}
fieldset.a table {
    border: 0;
    text-align: center;
    width: 550px;
}
fieldset.a td {
    vertical-align: bottom;
    text-align: center;
    font-weight: bold;
}
fieldset.a thead td:nth-of-type(1) {
    width: 100px;
}
fieldset.a thead td:nth-of-type(2) {
    width: 50px;
}
fieldset.a thead td:nth-of-type(3) {
    width: 50px;
}
fieldset.a thead td:nth-of-type(4) {
    width: 50px;
}
fieldset.a thead td:nth-of-type(5) {
    width: 50px;
}
fieldset.a thead td:nth-of-type(6) {
    width: 50px;
}
fieldset.a thead td:nth-of-type(7) {
    width: 50px;
}
fieldset.a input {
    width: 100%;
}
