多条件成立后执行答案

【问题标题】：Execute after multi conditions are true多条件成立后执行

【问题描述】：

我想制作动态表单域。例如，取决于表单字段的选择，我想显示隐藏字段或隐藏显示块。

例如，如果我选择第一个字段为“高中”，则显示“婚姻状况”字段。该字段默认隐藏。

见示例代码here

非常感谢！！

这里是 HTML

    <!-- fieldsets -->
    <fieldset>
        <h2 class="fs-title">Check your eligibility</h2>
        <h3 class="fs-subtitle">About yourself</h3>

这里是 JavaScript

    function myfunction(){
    var birthSelectedCountry = $("select#your-applicantCountry option:selected").val();
    // console.log(birthSelectedCountry);
    var country = "-" + birthSelectedCountry + "-";
    var eligibleCountries = "-61-65-81-86-82-91-266-223-95-102-175-104-106-112-120-140-146-156-163-221-190-177-181-183-187-261-262-189-194-56-182-38-279-287-267-115-123-280-288-286-137-281-289-282-283-149-270-284-285-1000-";

    var birthSpouseSelectedCountry = $("select#your-applicantCountry option:selected").val();
    // console.log(birthSpouseSelectedCountry);
    var spouseCountry = "-" + birthSpouseSelectedCountry + "-";
    var eligibleSpouseCountries = "-61-65-81-86-82-91-266-223-95-102-175-104-106-112-120-140-146-156-163-221-190-177-181-183-187-261-262-189-194-56-182-38-279-287-267-115-123-280-288-286-137-281-289-282-283-149-270-284-285-1000-";
    var maritalStatus = $("select#maritalStatus option:selected").val();
    // console.log(maritalStatus);
    var marital = "-" + maritalStatus + "-";
    var eligibleMarital = "-1-2-";
    var educationLevel = $("#educationLevel option:selected").val();
    var education = "-" + educationLevel + "-";
    var eligibleEducationLevel = "-2-3-";

console.log(education);
console.log(marital);
console.log(country);
console.log(eligibleEducationLevel.indexOf(education));
console.log(eligibleMarital.indexOf(marital));
console.log(eligibleCountries.indexOf(country));

if( eligibleEducationLevel.indexOf(education) < 0 && eligibleCountries.indexOf(country) < 0 ) { 
  console.log("Are you married?");
  // $('#marital').fadeIn();
  $('#marital').css('display', "block");
}

【解决方案1】：

试试这个：

JAVASCRIPT

if ($("#educationLevel").val() == "1"){
    $("#maritalStatus").show();
} else {
    // Do something else..
}

如果我正确理解了这个问题。

【解决方案2】：

在您的 document.ready() 事件中，通过引用它们的 ID 来隐藏所有控件。 document.ready() 函数用于初始化整个页面的整个行为。

$(document.ready(function(){

      //hide the maritalStatus dropdown initially at pageload.
      $('#maritalStatus').hide(); 
      $('#spouse-applicantCountry').hide();
      $('#maritalStatus').val(0); 
      $('#spouse-applicantCountry').val(0);

      //This the onchange event of the select
      $('#educationLevel').on('change', function() {
          $('#maritalStatus').show();

          //Put your conditions here
          if($('#maritalStatus').val() == "1"){
            $('#spouse-applicantCountry').show();  
          }
      });
}));

onChange 下拉菜单无法按预期正常工作，因为通常在定义函数之前呈现选择控件。

希望这会有所帮助！干杯！
