Javascript document.getElementById（'id'）。innerText不起作用

Question

我已经编写了代码来跟踪值并在span标签中显示，值跟踪有效，但显示部分不起作用（innerText，我也尝试使用值）有人可以帮助我，谢谢

function goAndSetTotal() {
    var amount = document.getElementById("amount").value;

    if (document.getElementById('gst').checked) {
        document.getElementById('subtotal').innerText = amount;
        document.getElementById('gst_box').innerText =  amount*10/100;
        document.getElementById('total').innerText = amount + (amount*10/100);

    } else {
        document.getElementById('subtotal').innerText = amount;
        document.getElementById('gst_box').innerText =  0;
        document.getElementById('total').innerText = amount;
    }

}

Answer 1

尝试innerHTML像

document.getElementById('subtotal').innerHTML = amount;

看一下它们之间的差异，假设您有以下html

<div id="Test"><b>InnerText and InnerHTML</b><div>

innerHTML 给 <b>InnerText and InnerHTML</b>

innerText 给 InnerText and InnerHTML
