我有php代码,我想编写一个脚本来从下拉列表中读取选项值,并在我更改选择时将每个值放在输入框中。请帮忙。

<html>

    //I want to write a script that will read the selected value and put in the input box
    </script>

  <body>
  <?php
    for ($i=0;$i<7;$i++)
    {
    ?>
    <select id='select$i'>
        <option value="1">Option1</option>
        <option value="2">Option2</option>
        <option value="3">Option3</option>

Try this:

    <html>
<head>
  <script type="text/javascript" src="jquery-2.1.1.min.js"></script>
</head>
<body>
<div class="category-panel">
  <?php
  for($i = 0; $i < 7; $i++)
  {
    ?>
    <select id='select<?php echo $i; ?>'>
      <option value="1">Option1</option>
      <option value="2">Option2</option>
      <option value="3">Option3</option>
    </select>
    <input type="text" name="name" id="inputoption<?php echo $i; ?>"/>
  <?php } ?>
  <br/>
</div>
<script>
  $("select").on("change", function()
  {

    $(this).next("input").val($(this).val());
  });
</script>
</body>
</html>

Better change the id into class :

更好地将id更改为类:

$(function() {
  $(document).on('change', '.selectMe', function() {
    $(this).next().val($(this).val());
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class='selectMe'>
  <option value="1">Option1</option>
  <option value="2">Option2</option>
  <option value="3">Option3</option>
</select>
<input type="text" name="name" class="inputoption" />
<select class='selectMe'>
  <option value="1">Option1</option>
  <option value="2">Option2</option>
  <option value="3">Option3</option>
</select>
<input type="text" name="name" class="inputoption" />

$("select[id^=select]").change(function(event){
    $(event.target).next().val($(event.target).val());
});

    <option value="3">Option3</option>
</select>
  <input type="text" name="name" class="inputoption"  />
