Question

如果有人可以帮我解决下面的代码，我将非常感激。我在IE中使用过调试器，但它没有给我任何错误。要求是XHTML Strict。谢谢！

function parseError(elem) {
    var enteredChar = elem.value.charAt(elem.value.length - 1);
    if (enteredChar === '') return;
    if (enteredChar.match(/[a-zA-Z]/))
        throw "value of " + (elem.name || elem.id) + " must be a digit";
}

document.myForm.value.onkeypress = function() {
    parseError(this);
};

<body>

<form action="#">
<div id="result">

<form name="value">
    <label for="value">Enter Numeric Value </label><input type="text" name="Value" />
</div>
</form>

我无法让我的脚本输出所需的验证或错误
