javascript-带有JQuery 1.7的IE8“对象不支持此属性或方法”

在IE 8中执行以下代码时,控制台将为第4行字符4显示错误“对象不支持此属性或方法”.这仅在IE 8中发生.我使用的是jquery-1.7.1.min. js

    $(document).ready(function () {

                    else {
                        $("[name='pfhTran']").removeAttr('checked');
                        $("[name='pfhTran']").attr('disabled', true);
                    }

                else if ($("[name='usdEquivalent']").val() > 15) {
                    $("[name='pfhTran']").attr('checked', true);
                    $("[name='pfhTran']").removeAttr('disabled');

                else {
                    $("[name='pfhTran']").removeAttr('checked');
                    $("[name='pfhTran']").attr('disabled', true);
                }
        }
        else {
            $("[name='pfhTran']").removeAttr('checked');
            $("[name='pfhTran']").attr('disabled', true);
        }

    });
});

解决方法:

方法“ indexOf”不是IE8数组方法的一部分.您应该可以使用jQuery.inArray：http://api.jquery.com/jQuery.inArray/快速解决此问题

更改：

states.indexOf($("[name='payToBankState']").val()) < 0

至：

$.inArray($("[name='payToBankState']").val(), states) < 0
