javascript - 带有简单 jquery VAT 的无效字符 script1014（在 IE 中）

Question

试图让这段代码触发，但我不断收到控制台错误，指的是代码的最后一行，但对我来说似乎很好，一直在测试不同的组合但无济于事，任何人都有任何见解:)

<script type="text/javascript" charset="UTF-8">
    $("#txtModalPricesIncPrice").keyup(function() {

        var price = $(this).val();
        var VAT = (parseFloat($("#txtModalPricesVAT").attr("value"))/100)+1;
        $("#txtModalPricesExPrice").val(price / VAT);


    });

    $("#txtModalPricesExPrice").keyup(function() {

        var price = $(this).val();
        var VAT = (parseFloat($("#txtModalPricesVAT").attr("value"))/100)+1;

        $("#txtModalPricesIncPrice").val(price * VAT);

    });

    $("#txtModalPricesVAT").keyup(function() {

        var price1 = $("#txtModalPricesIncPrice").val();
        var price2 = $("#txtModalPricesExPrice").val;
        var VAT = (parseFloat($("#txtModalPricesVAT").attr("value"))/100)+1;

        $("#txtModalPricesIncPrice").val(price1 * VAT);
        $("#txtModalPricesExPrice").val(price2 / VAT);

    });
</script>

表代码如下
