我在下面使用此代码，但似乎我的 setValue() 方法不起作用。有人可以指出这段代码有什么问题吗？

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

function rand ( n )
{
    document.getElementById("orderRefId").value =  ( Math.floor ( Math.random ( ) * n + 1 ) );
}

function setValue(amount1)
{
    myValue = amount1;
    document.getElementById("amount").value = myValue;
  }

        <tr>
            <td></td>
        </tr>   

        <input type="submit" value="Submit">
        </tbody>
        </table>
        </form>
    </body>
    </html>

注意：变量“amount1”来自我的 android。它不会导致问题，因为我在其他代码中使用它。

我将非常感谢任何想法。

JavaScript 在 WebView 中处于禁用的默认设置中。您需要先激活它。

YourWebView.getSettings().setJavaScriptEnabled(true);

您还需要更正您的 JavaScript。您调用 function document.getElementById(...)，但您的输入元素没有 Id 而是一个名称。所以你需要打电话document.getElementsByName(...)[0]。

1.你没有id为“amount”的DOMInputElement。您需要像这样更改html：

<input type="text" onLoad = "setValue()" name="amount" id="amount" value=""/>

或者像这样的js：

function setValue(amount1)
{
    myValue = amount1;
    document.frmPayment.amount.value = myValue;
}

2.第二个问题是您不能将 onLoad 事件附加到输入元素。您可以做的是将 <script/> 与 setValue() 调用或将您的 <body> 标记更改为：

<body onLoad="rand(200000);setValue();">

           function text() {
        var dt = new Date();
        dt.format("dd-mmm-yyyy");
        var newdt = dt.getFullYear();
        var tt = document.getElementById("ctl00_ContentPlaceHolder1_txtPolicyStartDate").value;           
        var dt2 = new Date.parseLocale(tt, 'dd-MMM-yyyy');     

        dt2.setFullYear(dt2.getFullYear() + 1);
        dt2.setDate(dt2.getDate() - 1);
        document.getElementById("ctl00_ContentPlaceHolder1_txtPolicyExpiryDate").value = dt2.format("dd-MMM-yyyy");
        return dt2;
    }
