javascript - jquery 在函数中的 Focusout 上执行双重触发代码

Question

我有一个 jquery 的问题，我需要把输入焦点上的每个事件都移出

这是我的 code.js

var checkFocusout = "";
    $("input").on("focusout", function(){

        checkFocusout = $(this).attr('name');
        console.log(checkFocusout);
    });

这是我的表格

首先，我在第一个输入中输入一个值。

这是我在浏览器中的控制台

应该是这样的

但是，我在第二个输入中输入了值

还有浏览器上的这个控制台。

在控制台中应该做一次，但它做了两倍

我的html

<div class="col-md-6">
        <div class="form-group row"><label class="col-sm-4 col-form-label">Number of Adult</label>
            <div class="col-sm-8"><input type="number" name="noa_2" class="form-control text-right" value="0"
                                         onchange="calculatePrice(2)" price="111"></div>

        </div>
    </div>

我的全功能javascript

function calculatePrice(product_id) {
    var noa = parseInt($('input[name="noa_'+product_id+'"]').val());
    var noc = parseInt($('input[name="noc_'+product_id+'"]').val());
    var noi = parseInt($('input[name="noi_'+product_id+'"]').val());
    var total_pax = (noa+noc+noi)+parseInt(available_of_product[product_id]);
    var vat = parseInt($('input[name="v_'+product_id+'"]').val());
    var t = parseInt($('input[name="t_'+product_id+'"]').val());
    var nt = parseInt($('input[name="nt_'+product_id+'"]').val());
    var public_adult = parseInt($('input[name="noa_'+product_id+'"]').attr('price'));
    var public_child = parseInt($('input[name="noc_'+product_id+'"]').attr('price'));
    var public_infant = parseInt($('input[name="noi_'+product_id+'"]').attr('price'));
    var number_of_pax = $("#available_span_"+product_id).attr('number_of_pax');
    var checkFocusout = "";


    $("input").on("keyup", function(){

        checkFocusout = $(this).attr('name');
        console.log(checkFocusout);
    });
    if (total_pax > number_of_pax){
        $("#alertMessageBody").html('<p>The number of passengers exceeds the maximum number of products.</p>');
        $('#alertMessage').modal('show')
    }else{

    }
}

你可以这样做

$("input").unbind().on("focusout", function(event){
        console.log(i)
        checkFocusout = $(this).attr('name');
        console.log(checkFocusout);
        i=i+1
    });
