Jquery无效参数IE7-IE9

Question

我有一个从购物车中删除产品的链接，适用于IE7-IE9以外的所有浏览器。

我在IE控制台日志中收到此错误：

SCRIPT87: Invalid argument. 
jquery.min.js, line 4 character 7871

脚本：https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js

它的工作方式有点像手风琴，当删除时它“向上滑动”并且看起来这种jquery效果正在引起它。发生此错误时，也不会删除产品。我现在一无所知，任何人都有任何想法？

修改

if ( document.documentElement.currentStyle ) {
currentStyle = function( elem, name ) {
    var left, rsLeft, uncomputed,
        ret = elem.currentStyle && elem.currentStyle[ name ],
        style = elem.style;

    // Avoid setting ret to empty string here
    // so we don't default to auto
    if ( ret === null && style && (uncomputed = style[ name ]) ) {
        ret = uncomputed;
    }

    // If we're not dealing with a regular pixel number
    // but a number that has a weird ending, we need to convert it to pixels
    if ( !rnumpx.test( ret ) && rnum.test( ret ) ) {

        // Remember the original values
        left = style.left;
        rsLeft = elem.runtimeStyle && elem.runtimeStyle.left;

        // Put in the new values to get a computed value out
        if ( rsLeft ) {
            elem.runtimeStyle.left = elem.currentStyle.left;
        }
        style.left = name === "fontSize" ? "1em" : ( ret || 0 );
        ret = style.pixelLeft + "px";

        // Revert the changed values
        style.left = left;
        if ( rsLeft ) {
            elem.runtimeStyle.left = rsLeft;
        }
    }

    return ret === "" ? "auto" : ret;
};
    }

错误发生在：

style.left = name === "fontSize" ? "1em" : ( ret || 0 );
