Internet Explorer 8错误-对象不支持此属性或方法

Question

当我尝试提交表单时，我在IE上遇到错误。错误如下，但我不知道如何解决。

IE错误-对象不支持此属性或方法-Mailbox-details.php-行：397-字符：5

下面是代码段...

第397行是从底部开始的第3行... jQuery_1_7_1（“＃store_notes”）。val（“”）;

 <script>
/*
$("input").click( function(e) {
    alert();
    e.preventDefault();
})
*/
jQuery(document).ready(function( $ ) {
    jQuery( "#renewal_date" ).datepicker({ dateFormat: "mm-dd-yy" });       
    //alert(jQuery_1_7_1.ui);
});

如果您对项目使用编译，则可以考虑在入口点的顶部添加

import 'core-js'

目前core-js polyfill library是提供跨浏览器支持的最简单方法
