我在使用jquery时遇到问题,我需要获取输入焦点上的每个事件
这是我的code.js
var checkFocusout = "";
$("input").on("focusout", function(){
checkFocusout = $(this).attr('name');
console.log(checkFocusout);
});
此我的控制台在浏览器中
应该是这样。
但是,我将值输入到第二个输入中
以及浏览器上的此控制台。
在控制台中应该执行一次,但是要执行两次]
我的html
<div class="col-md-6"> <div class="form-group row"><label class="col-sm-4 col-form-label">Number of Adult</label> <div class="col-sm-8"><input type="number" name="noa_2" class="form-control text-right" value="0" onchange="calculatePrice(2)" price="111"></div> </div> <div class="form-group row"><label class="col-sm-4 col-form-label">Number of Child</label> <div class="col-sm-8"><input type="number" name="noc_2" class="form-control text-right" value="0" onchange="calculatePrice(2)" price="222"></div> </div> <div class="form-group row"><label class="col-sm-4 col-form-label">Number of Infant</label> <div class="col-sm-8"><input type="number" name="noi_2" class="form-control text-right" value="0" onchange="calculatePrice(2)" price="0"></div> </div> <div class="form-group row"><label class="col-sm-4 col-form-label">Discounts</label> <div class="col-sm-8"><input type="number" name="d_2" class="form-control text-right" value="0" onchange="calculatePrice(2)"></div> </div> <div class="form-group row"><label class="col-sm-4 col-form-label">Total</label> <div class="col-sm-8"><input type="number" name="t_2" readonly="" class="form-control text-right"></div> </div> <div class="form-group row"><label class="col-sm-4 col-form-label">Vat</label> <div class="input-group col-sm-8"> <div class="input-group-prepend"> <div class="input-group-text">%</div> </div> <input type="number" name="v_2" class="form-control text-right" value="7" onchange="calculatePrice(2)"> </div> </div> <div class="form-group row"><label class="col-sm-4 col-form-label">Net Total</label> <div class="col-sm-8"><input type="number" name="nt_2" readonly="" class="form-control text-right"></div> </div> </div>
我的全功能javascript
function calculatePrice(product_id) {
var noa = parseInt($('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{
}
}
我对jquery有问题,我需要使每个事件都集中在输入焦点上。这是我的code.js var checkFocusout =“”; $(“ input”)。on(“ focusout”,function(){checkFocusout = $(this).attr('...
每次调用事件时,函数calculatePrice
都会创建事件。因此,如果您在函数开始时删除事件,它将可以正常工作。
