在日期选择器填充字段之前发生模糊事件

时间：2019-07-04 12:23:59

标签： javascript jquery html datepicker onblur

我举了一个最小的例子来说明这个问题。我在此处阅读了有关SO的一些问题/答案，

onSelect: function() {        
                    date_input.blur();
            },

选择日期选择器，尽管这对我仍然无效。知道为什么吗？

如日期选择器事件文档中所述：https://bootstrap-datepicker.readthedocs.io/en/latest/events.html#changedate

您需要收听changeDate事件！

    <!--
    function validate() {

      if (document.invia_dati.nome.value == "") {
        alert("Please provide your name!");
        document.invia_dati.nome.focus();
        return false;
      }
    }

    function validate_field(field_id, error_id) {
      var field = document.getElementById(field_id);
      var perror = document.getElementById(error_id);
      if (field.value === "") {
        perror.style.display = "block";
        field.style.borderColor = "red"
        field.style.boxShadow = "1px 1px 5px red";
      } else {
        perror.style.display = "none";
        field.style.borderColor = "LightGrey"
        field.style.boxShadow = "0px 0px 0px LightGrey";
      }
    }
    //-->

    $(document).ready(function() {
      var date_input = $('input[name="data_nascita"]'); //our date input has the name "data_nascita"
      var container = $('.bootstrap-iso form').length > 0 ? $('.bootstrap-iso form').parent() : "body";
      date_input.datepicker({
        format: 'dd/mm/yyyy',
        container: container,
        todayHighlight: true,
        autoclose: true,
        orientation: "top"
      })
      date_input.on('changeDate', function(e) {
        date_input.blur()
      })
    })

答案 1 :(得分：1)

您可以通过以下方式更改此事件

onblur="return(validate_field('date', 'dob-errore'));"

致onchange="return(validate_field('date', 'dob-errore'));"

也许您的问题只与日期选择器有关？
