javascript - 脚本438 : Object doesn't support property or method 'filter' IE10

Question

我从网络服务加载一些数据并尝试过滤它。

var topLevelProductTypes = [];

topLevelProductTypes = productTypesArray.filter(function (pt) {
     return (pt.NS_designcentreproducttypeid.Id === null);
});

我收到错误 SCRIPT438:对象不支持属性或方法“过滤器”

将此添加到您的标题中 <meta http-equiv="X-UA-Compatible" content="IE=edge" />

和productTypesArray您的代码中看起来未声明。我假设它被分配给 array

if( Object.prototype.toString.call( productTypesArray) === '[object Array]' ) {
    alert( 'It is an array' );
}
