我有带数字计数的选择选项,因此当用户通过此数字选择任何数字时,我现在需要克隆div标签个人信息,例如:-选择8个克隆8次..
我尝试通过use(for loop)来做到这一点,但是我在运行时遇到问题,我看到克隆超过了这个数字,例如:-选择8个克隆16次
这是html代码和我的js代码
$('#c3').change(function() {
$('.cloneHere').empty();
var count = $('#c3').val();
for (i = 1; count > i; i++) {
var clone = $('.rowClone').clone();
$('.cloneHere').append(clone);
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class='col-xs-3'>
<label for="">count of person</label>
<select class='form-control select2' name="" id="c3">
<option value="" selected disabled hidden>Choose here</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
</select>
</div>
</div>
</div>
</div>
</div>
</div>
<div class='col-md-12'>
<div class='box box-primary'>
<div class='box-header with-border'>
<h3 class='box-title'>Information of Person</h3>
</div>
<div class='form-group'>
<div class='box-body rowClone2'>
<div class=' row'>
<div class=' col-sm-3'><label for="">Person 1</label></div>
</div>
<div class='row rowClone'>
<div class='col-xs-6 col-md-3'>
<input type="text" class="form-control">
</div>
<div class='col-xs-6 col-md-3'>
<input type="text" class="form-control">
</div>
<div class='col-xs-6 col-md-3'>
<input type="tel" class="form-control">
</div>
<div class='col-xs-6 col-md-3'>
<input type="text" class="form-control">
</div>
</div>
<br>
<div class="row cloneHere">
</div>
</div>
答案 0 :(得分:3)
您面临的问题来自以下行:var clone = $('.rowClone').clone();
第一个克隆很好,因为只有1个.rowClone
存在,下一次存在多个.rowClone
并附加所有这些克隆。
您有2种解决方案,可以使用var clone = $('.rowClone:first').clone();
或将var clone = $('.rowClone').clone();
移至for loop
问题的演示,运行它并查看控制台
$('#c3').change(function() {
$('.cloneHere').empty();
var count = $('#c3').val();
for (i = 1; count > i; i++) {
console.log("Number of .rowClone that exist = " + $('.rowClone').length)
var clone = $('.rowClone').clone();
$('.cloneHere').append(clone);
}
});
