如何从js

Question

我想将js中的变量输出到html标签，这样我就可以在页面的特定位置看到结果。这是代码：

<script type="text/javascript">
function doMath()
{
    // Capture the entered values of two input boxes
    var my_input1 = document.getElementById('my_input1').value;
    var my_input2 = document.getElementById('my_input2').value;
    var my_input3 = document.getElementById("my_input3").value;
    var my_input4 = document.getElementById("my_input4").value;
        //alert(form.elements["my_input2"].value);
    //var my_input3 = document.getElementById('my_input3').value;

    // Add them together and display
    var sum = parseInt(my_input1) / parseInt(my_input2) *     parseInt(my_input3) * parseInt(my_input4);
    document.write(sum);
}

Answer 1

我们假设您要在ID为sum

的div中显示响应

<div id="sum"></div>

为此，请更新

document.write(sum);

到

document.getElementById("sum").innerHTML = sum;
