数组拼接在IE中引发错误

IE7 and IE8 are not letting me splice my array (Safari, Chrome, Firefox work):

IE7和IE8不让我拼接我的阵列（Safari，Chrome，Firefox工作）：

        lzaCreateAd1.weatherArray = new Array();
        var jWeatherIcon = $('.weatherIcon');

        jWeatherIcon.bind('click', function (){
            var targetID = $(this).attr('id') + 'Box',
            idVal = targetID.substr(5,1);

            var jTargetBox = $('#'+targetID);

            if (jTargetBox.hasClass('inactive')) {
                jTargetBox.removeClass('inactive').addClass('active');
                lzaCreateAd1.weatherArray.push(idVal);
            } else if (jTargetBox.hasClass('active')) {
                jTargetBox.removeClass('active').addClass('inactive');
                lzaCreateAd1.weatherArray.splice(lzaCreateAd1.weatherArray.indexOf(idVal),1);
            }
        });

IE throws the following error: "Object doesn't support this property or method" for this line:

IE抛出以下错误：“对象不支持此属性或方法”此行：

lzaCreateAd1.weatherArray.splice(lzaCreateAd1.weatherArray.indexOf(idVal),1);

lzaCreateAd1.weatherArray.splice（lzaCreateAd1.weatherArray.indexOf（idVal），1）;

Any ideas? Or other ways to remove an array item by value? Thanks in advance!

有任何想法吗？或者按值删除数组项的其他方法？提前致谢！

Array.indexOf is not supported by Internet Explorer before version 9. You can use the jQuery's $.inArray utility function, or any other shim/polyfill you want instead.

在版本9之前，Internet Explorer不支持Array.indexOf。您可以使用jQuery的$ .inArray实用程序函数或您想要的任何其他填充/填充。

lzaCreateAd1.weatherArray.splice($.inArray(idVal, lzaCreateAd1.weatherArray) ,1);
