js传url中文参数乱码问题

$("#btnKeyWord").click(function () {
        window.open("/Atraction/Atraction.aspx?keyword=" + encodeURI(encodeURI($("#txtKeyWord").val())));
    });

注意：这里要两次转码

$("#searchContent").val(decodeURI(getQueryString("keyword")));
    if (getQueryString("keyword") == null) {
        bindData('', _PageSize, 0, isPrice, lowPrice, highPrice, orderStr, atrType, level);
    }
    else {
        bindData(decodeURI(getQueryString("keyword")), _PageSize, 0, isPrice, lowPrice, highPrice, orderStr, atrType, level);
    }

解码
