我正在使用respond.js（该库为+1），并且对象的以下函数出现错误：
translate = function (styles, href, media) {
// here I got 'undefined' error in IE 8
var qs = styles.match(/@media[^\{]+\{([^\{\}]*\{[^\}\{]*\})+/gi),
ql = qs && qs.length || 0;
//try to get CSS path
href = href.substring(0, href.lastIndexOf("/"));
var repUrls = function (css) {
return css.replace(/(url\()['"]?([^\/\)'"][^:\)'"]+)['"]?(\))/g, "$1" + href + "$2$3");
},
useMedia = !ql && media;
//if path exists, tack on trailing slash
if (href.length) {
href += "/";
}
//if no internal queries exist, but media attr does, use that
//note: this currently lacks support for situations where a media attr is specified on a link AND
//its associated stylesheet has internal CSS media queries.
//In those cases, the media attribute will currently be ignored.
if (useMedia) {
ql = 1;
}
for (var i = 0; i < ql; i++) {
var fullq, thisq, eachq, eql;
//media attr
if (useMedia) {
fullq = media;
rules.push(repUrls(styles));
}
//parse for styles
else {
fullq = qs[i].match(/@media *([^\{]+)\{([\S\s]+?)$/) && RegExp.$1;
rules.push(RegExp.$2 && repUrls(RegExp.$2));
}
eachq = fullq.split(",");
eql = eachq.length;
for (var j = 0; j < eql; j++) {
thisq = eachq[j];
mediastyles.push({
media: thisq.split("(")[0].match(/(only\s+)?([a-zA-Z]+)\s?/) && RegExp.$2 || "all",
rules: rules.length - 1,
hasquery: thisq.indexOf("(") > -1,
minw: thisq.match(/\(\s*min\-width\s*:\s*(\s*[0-9\.]+)(px|em)\s*\)/) && parseFloat(RegExp.$1) + (RegExp.$2 || ""),
maxw: thisq.match(/\(\s*max\-width\s*:\s*(\s*[0-9\.]+)(px|em)\s*\)/) && parseFloat(RegExp.$1) + (RegExp.$2 || "")
});
}
}
applyMedia();
},
还有其他解决方法吗？我尝试过不同的...
