ie8下 JS全选功能报错 求达人帮忙看下代码

// ????

    }

    // ?????
    calculate();
}

var atdRealPrsn = 4;
var maxDayCha = 0;

这是一段全选复选框的JQ   在IE9以上都没问题  在IE8下 var stsStatDayVal = trim(stsStatDay[j-1][i].value); 这段总报错为空或不是对象，求高人解答  在线等  谢谢

解决方案

我写的东西刚好和你的相反,用其它浏览器正常,用IE8以下正常,IE8以上就出现畸形。

解决方案二：

一个全选复选框这多简单的东西,居然这么长?
$("input[name=checkbox]").attr("checked",true);

解决方案三：

 var stsStatDayVal = trim(stsStatDay[j-1][i].value);
 改成
 var stsStatDayVal = trim(stsStatDay[j-1][0].value);
