Question

我试过这段代码。我的问题是如何将文本的值传递给持有者，每个输入应该用逗号分隔，不应重复输入值，任何人都可以帮助我提前谢谢。

<input type="text" name="text" id="text">

<button type="button" id="button"> Button </button>
<Br> <Br>
<input type="holder" id="holder" name="holder">


<script>
$(document).ready(function() {

  $("#button").click(function() {
        $('#text').each(function() {
        if ($(this).val() == $current.val() && $(this).attr('id') != $current.attr('id'))
        {
            alert('duplicate found!');
        }
    var data = [];
    $.each($("#text"), function() {
      data.push($(this).attr("value"));
    });
        $('#holder').val(data.join(","));;

  });

});
</script>

Answer 1

请使用以下代码替换您的脚本代码：

<script>
$(document).ready(function() {

 var data = [];

 $("#button").click(function() {


    $.each($("#text"), function() {

      if(data.indexOf($("#text").val())<0){
       data.push($("#text").val());
       $("#text").val('');
     }else{
      alert('duplicate found');
    }

    $('#holder').val(data.join(","));

  });



});

 });
  </script>

试试这个..

$("#button").click(function() {
  $text = $('#text');
  $textval = $text.val();
  $holder = $('#holder');
  $holderval = $holder.val();
  if ($holderval.trim().length) {
    var duplicate;
    duplicate = $holderval.split(',').filter(function(hv) {
      return hv == $textval;
    })
    if (duplicate.length) {
      alert("Duplicate found");
      return false;
    }
    $holder.val($holderval += ',' + $textval);
  } else {
    $holder.val($holderval += $textval);
  }
  $text.val('');
});

$("#button").click(function() {
  $text = $('#text');
  $textval = $text.val();
  $holder = $('#holder');
  $holderval = $holder.val();
  if ($holderval.trim().length) {
    var duplicate;
    duplicate = $holderval.split(',').filter(function(hv) {
      return hv == $textval;
    })
    if (duplicate.length) {
      alert("Duplicate found");
      return false;
    }
    $holder.val($holderval += ',' + $textval);
  } else {
    $holder.val($holderval += $textval);
  }
  $text.val('');
});
