如何在JavaScript中仅隐藏文本值(How to hide only text value in JavaScript)

我在JavaScript和Html代码中有一些代码这很好（？）但问题是文本框也消失了。 有人可以帮忙吗？

function getProductBarcode() {
    var barcode = $('#productBarcode').val();
    document.getElementById('#pos-RightTitle').style.display = 'block';
   
    $.post('functions/pos-calculation-process.php', {barcode:barcode})
        .done(function(data){
            $('#pos-RightTitle').html(data);
            setTimeout(function(){
                $('#productBarcode').hide();
            }, 300)
        });
    
    return false;
} 
  
<div class="input-group">
    <span class="input-group-addon">
        <span class="glyphicon glyphicon-shopping-cart" aria-hidden="true"></span>
    </span>
    <input type="text" class="form-control" id="productBarcode"onchange = "getProductBarcode()" placeholder="Scan Barcode" aria-describedby="basic-addon1">  
</div>

    var barcode = $('#productBarcode').val();
    document.getElementById('#pos-RightTitle').style.display = 'block';

 如果您只想清除文本表单输入，请在setTimeout函数中替换此代码： 
 
 $('#productBarcode').hide(); 
 
 有： 
 
$('#productBarcode').val('');
If you only want to clear the text form input replace this code in setTimeout function:
 
$('#productBarcode').hide();
 
with:
 
$('#productBarcode').val('');
