Question

我正在尝试循环并根据存储在数组中的值附加多个容器，然后相应地设置这些值，但我目前正在复制这些值，并且无法在每次循环时获取不同的值循环。

var arr_tele = ['02991812376', '02982919291'];

//Prevent Duplicates.
$(".teledivcontain").remove();

//Append Container for numbers
$("#telediv").append('<div class="form-group col-md-3" id="teledivcontain"> </div>');

//Loop and append fields for each number
for (i in arr_tele) {
  $("#teledivcontain").append('<input type="text" class="form-control telenumber" placeholder="No number currently" disabled><div class="form-group col-md-3"><button type="submit" class="btn btn-primary form-control detach">Detach</button></div>').find('input:text').val(arr_tele[i]);
}

.fieldpos {
  margin-left: 45px;
  width: 40%;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="panel-body row fieldpos">
  <fieldset class="form-group">
    <label for="telenum">Your Telephone Numbers</label>
    <div class="row">
      <div id="telediv">
      </div>
    </div>
  </fieldset>
</div>

我遗漏了一些未成年人但却无法看到任何人的想法？

Answer 1

你必须找到附加的最后一个输入然后分配值，所以只需添加:last选择器就能完成工作：

.find('input:text:last').val(arr_tele[i])

或者您可以直接使用<input value="'+arr_tele[i]+'" ...分配值。

希望这有帮助。

var arr_tele = ['02991812376', '02982919291'];

//Prevent Duplicates.
$(".teledivcontain").remove();

//Append Container for numbers
$("#telediv").append('<div class="form-group col-md-3" id="teledivcontain"> </div>');

//Loop and append fields for each number
for (i in arr_tele) {
  $("#teledivcontain").append('<input type="text" class="form-control telenumber" placeholder="No number currently" disabled><div class="form-group col-md-3"><button type="submit" class="btn btn-primary form-control detach">Detach</button></div>').find('input:text:last').val(arr_tele[i]);
}

.fieldpos {
  margin-left: 45px;
  width: 40%;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="panel-body row fieldpos">
  <fieldset class="form-group">
    <label for="telenum">Your Telephone Numbers</label>
    <div class="row">
      <div id="telediv">
      </div>
    </div>
  </fieldset>
</div>

只需在HTML中添加属性即可添加。请注意循环'<input type="text" ... value="' + arr_tele[i] + '"disabled>：

＆＃13;

var arr_tele = ['02991812376', '02982919291'];

//Prevent Duplicates.
$(".teledivcontain").remove();

//Append Container for numbers
$("#telediv").append('<div class="form-group col-md-3" id="teledivcontain"> </div>');

//Loop and append fields for each number
for (i in arr_tele) {
  $("#teledivcontain").append('<input type="text" class="form-control telenumber" placeholder="No number currently" value="' + arr_tele[i] + '"disabled><div class="form-group col-md-3"><button type="submit" class="btn btn-primary form-control detach">Detach</button></div>');
}

＆＃13;

.fieldpos {
  margin-left: 45px;
  width: 40%;
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="panel-body row fieldpos">
  <fieldset class="form-group">
    <label for="telenum">Your Telephone Numbers</label>
    <div class="row">
      <div id="telediv">
      </div>
    </div>
  </fieldset>
</div>

循环舍入数组，附加输入文本框，然后设置这些文本框的值
