Question

到目前为止，我没有成功地让第一个输入按钮启动表移位功能。目前我正在测试功能。我已经尽力通过一些教科书和在线搜索来审查格式，我想我的语法是正确的。寻找关于为什么tableShifts（）没有从按钮Calculate Shifts中引用的建议。谢谢。

Answer 1

函数tableShiftsss中的

：

    var gotoVert.value = curVert - pinVert;
    var gotoLat.value = curLat + pinLat;
    var gotolong.value = curLong - pinLong;

这不是有效的EcmaScript方言（如javascript）。

您可能希望将其更改为：

function tableShifts(){           
    var curVert = Number(document.getElementById("curVert").value),
         curLat = Number(document.getElementById("curLat").value), 
        curLong = Number(document.getElementById("curLong").value), 

        pinVert = Number(document.getElementById("curVert").value),
         pinLat = Number(document.getElementById("curVert").value),
        pinLong = Number(document.getElementById("curVert").value);

    document.getElementById("gotoVert").value = curVert - pinVert;
    document.getElementById("gotoLat").value  = curLat + pinLat;
    document.getElementById("gotolong").value = curLong - pinLong; 
}

祝你好运！

Answer 2

在你的tableShiftsss（）中，你说：

var gotoVert.value

虽然它应该是：

document.getElementById("gotoVert").value

这适用于所有这三个陈述。

此外，value函数返回的字符串不是int，因此您不能只添加结果。您将需要转换为类似的int：

var curVert = parseInt(document.getElementById("curVert").value);

您可能有其他语法错误，但这取决于您使用浏览器Javascript控制台进行调试。
