当特定输入字段为焦点时，jQuery禁用输入字段

Question

我有两个输入字段，如果另一个输入字段中有值，我希望另一个输入字段被禁用。我尝试使用jQuery，但没有任何反应。有人知道我该怎么办吗？谢谢

我的输入字段

<ul>
<li id="fixedSalaryList"><b>Fixed Salary (Monthly)</b>
    <a href="#" class="show-input">$<?php echo $data['app1']['salary']; ?> <img src="<?php echo $dirimg; ?>/arrow-right.svg"></a>
    <input type="text" name="salary[]" id="fixedSalary" class="assest-input inputNumber" value="<?php echo $data['app1']['salary']; ?>" inputmode="numeric">
</li>
<li id="selfEmployedList"><b>Self-Employed Income (Annually)</b>
    <a href="#" class="show-input">$<?php echo $data['app1']['selfEmployedIncome']; ?><img src="<?php echo $dirimg; ?>/arrow-right.svg"></a>
    <input type="text" name="selfEmployedIncome[]" id="selfEmployed" class="assest-input inputNumber" value="<?php echo $data['app1']['selfEmployedIncome']; ?>" inputmode="numeric">
</li>
</ul>

jQuery

 $('input').on('input', function() {
    $(this).closest('li').find('input').not(this).prop('disabled', this.value.length)
  });

$('li input').on('input', function() {
    $(this).closest('li').find('input').not(this).prop('disabled', this.value.length)
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li id="fixedSalaryList"><b>Fixed Salary (Monthly)</b>
    <a href="#" class="show-input">$</a>
    <input type="text" name="salary[]" id="fixedSalary" class="assest-input inputNumber"  inputmode="numeric">
</li>
<li id="selfEmployedList"><b>Self-Employed Income (Annually)</b>
    <a href="#" class="show-input">$</a>
    <input type="text" name="selfEmployedIncome[]" id="selfEmployed" class="assest-input inputNumber"  inputmode="numeric">
</li>
</ul>

Answer 1

您可以执行以下操作：

$(document).ready(function() {
  $("#fixedSalary").on("input", function() {
    if ($("#fixedSalary").val() != "") {
      $("#selfEmployed").prop('disabled', true);
    } else {
      $("#selfEmployed").prop('disabled', false);
    }
  });

  $("#selfEmployed").on("input", function() {
    if ($("#selfEmployed").val() != "") {
      $("#fixedSalary").prop('disabled', true);
    } else {
      $("#fixedSalary").prop('disabled', false);
    }
  });
});

$("#btnReset").click(function() {
  $("#fixedSalary").prop('disabled', false);
  $("#selfEmployed").prop('disabled', false);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
  <li id="fixedSalaryList"><b>Fixed Salary (Monthly)</b>
    <a href="#" class="show-input">$</a>
    <input type="text" name="salary[]" id="fixedSalary" class="assest-input inputNumber" inputmode="numeric">
  </li>
  <li id="selfEmployedList"><b>Self-Employed Income (Annually)</b>
    <a href="#" class="show-input">$</a>
    <input type="text" name="selfEmployedIncome[]" id="selfEmployed" class="assest-input inputNumber" inputmode="numeric">
  </li>
</ul>

<input type="submit" text="Reset" id="btnReset">

Answer 2

您可以通过change()事件来完成此操作

jQuery

$(document).ready(function(){
  $("#selfEmployed").change(function(){
   $("#fixedSalary").prop('disabled', true);
  });

  $("#fixedSalary").change(function(){
   $("#selfEmployed").prop('disabled', true);
  });

});

现在它将同时起作用。
