通过减去选项计算总数 - 动态形式 - Yii2

Question

我想计算 "qualification" 输入字段中嵌套表单的 "score" 个字段的总数。目前我可以添加字段 "score" 并在 "qualification" 中显示总数，但问题是当我删除字段 "score" 我没有更新 "qualification" 字段但它仍然存在结果相同。额外的可以设置一些限制以避免通过等级，例如这不大于 10，如果你能帮助我，我将不胜感激。

Js

$(document).on('keyup', 'input[id^="questions-"]', function() {
var sum = 0;
jQuery(".dynamicform_wrapper .remove-item").each(function(indexQuestion) {

    var amount = $('#questions-' + indexQuestion + '-score').val().replace(/,/g , "");

    sum += parseFloat(amount);
});
$('#question-qualification').val(sum);

});

Answer 1

您需要添加一个新的 Javascript Events afterDelete 事件，您的 JS 将是：

$(document).on('keyup', 'input[id^="questions-"]', function() {
    var sum = 0;
    jQuery(".dynamicform_wrapper .remove-item").each(function(indexQuestion) {
        var amount = $('#questions-' + indexQuestion + '-score').val().replace(/,/g, "");    
        sum += parseFloat(amount);
    });
    $('#question-qualification').val(sum);
});
$(".dynamicform_wrapper").on("afterDelete", function(e) {
    var sum = 0;
    jQuery(".dynamicform_wrapper .remove-item").each(function(indexQuestion) {
        var amount = $('#questions-' + indexQuestion + '-score').val().replace(/,/g, "");
        sum += parseFloat(amount);
    });
    $('#question-qualification').val(sum);
});
