我是网络开发的新手,我正在使用Bootstrap在HTML中开发一个表单。所以我有一个如下所示的div:
<div class="form-group">
<label class="col-md-4 control-label" >Users</label>
<div class="col-md-4 inputGroupContainer">
<div class="input-group">
<span class="input-group-addon"><i class="glyphicon glyphicon-tasks"></i></span>
<select name="state" class="form-control selectpicker" >
<option value=" " >Please select the number of users</option>
<option>1</option>
<option>2</option>
<option >3</option>
</select>
</div>
</div>
</div>
因此,根据数字的选择,我想动态创建文本框,如下面的div。
<div class="form-group">
<label class="col-md-4 control-label">Username</label>
<div class="col-md-4 inputGroupContainer">
<div class="input-group">
<span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
<input name="phone" placeholder="Username" class="form-control" type="text">
</div>
</div>
</div>
例如,如果他选择1,那么如果选择2则会出现一个文本框,然后应该出现2。感谢任何帮助。

试试这个
$('.selectpicker[name=state]').change(function() {
var i = 0;
//$('.input-group').children('input').remove() *for reset the inbox on change*
while (i < parseInt($(this).val())) {
$('.input-group').append('<input name="phone" placeholder="Username" class="form-control" type="text">')
i++;
}
})
