Question

我有一个计算几个值并吐出成绩的表单。我希望这个等级可以提供。它们已经以整数形式出现，即：100.00。

var acqAmount1 = Number(jQuery("#edit-submitted-acquisition-amount-1").val().replace(/,/g,""));
    var acqAmount2 = Number(jQuery("#edit-submitted-acquisition-amount-2").val().replace(/,/g,""));
    var acqTotal = 0;

    if (acqAmount1) {
        acqAmount1 = parseFloat(acqAmount1);
    } else {
        acqAmount1 = 0;
    }

    if (acqAmount2) {
        acqAmount2 = parseFloat(acqAmount2);
    } else {
        acqAmount2 = 0;
    }

    if (acqAmount1 > 0 && acqAmount2 > 0) {
        acqTotal = ((acqAmount2 - acqAmount1) / acqAmount1 * 100).toFixed(2);
    } else {
        acqTotal = 0;
    }

    jQuery("#edit-submitted-acquisition-percent-change").val( acqTotal );

    grade += getAcquisitionPoints(acqTotal);

我尝试了+= '%' + '%'的几种方法，但似乎无法做到正确。

Answer 1

更改目标input元素：

type="number"

要：

type="text"

应该解决问题。使用：

jQuery("#edit-submitted-acquisition-percent-change").val( acqTotal + '%' );

在jQuery中在计算值的末尾附加％？
