JavaScript代码在文本框中显示div消息 - javascript

以下是我用来计算总计的脚本。

<script type="text/javascript" >
    function calculateTotal() {
        // price per unit 
        var priceEL = document.getElementById('price');
        // get input element from DOM
        var inputEl = document.getElementById('quantity');
        // read quantity from the input element (it is read as a string)

         var priceSting = priceEL.value;
        var quantitySting = inputEl.value;
        // convert string value from the form element into integer (or float if needed)
        var quantity = parseInt(quantitySting);
        var price = parseInt(priceSting);
        // calculate total
        var total = price * quantity;
        // get element that displays total from DOM
        var displayEl = document.getElementById('total')
        // display total value in target element
        displayEl.innerHTML = total;
    }
</script>

现在我的代码在div标签内回显总值...如下

<div id ="total"></div>

我需要在文本框下面显示总计。

<input type="textbox" name="total" id ="total"></td>

参考方案

尝试这个：

document.getElementById("total").value = total;
