IE8 "Object doesn't support this property or method" 与 JQuery 1.7

Question

当在 IE 8 中执行以下代码时，控制台显示第 4 行第 4 个字符的错误 "Object doesn't support this property or method"。这只发生在 IE 8 中。我使用的是 jquery-1.7。1.min.js

    $(document).ready(function () {

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

变化：

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

收件人：

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