我正在创建执行不同任务的各种流程.其中一个,只有其中一个,有一个安全模块,可以创建PyCrypto对象.所以我的程序启动,创建各种进程,处理消息的进程使用安全模块解密,我得到以下错误:

   firstSymKeybin = self.cipher.decrypt(encFirstSymKeybin, '')
  File "/usr/local/lib/python2.7/dist-packages/Crypto/Cipher/PKCS1_v1_5.py", line 206, in decrypt
    m = self._key.decrypt(ct)

    return pubkey.pubkey.decrypt(self, ciphertext)

尝试在OpenLayers 3中使用编码折线时遇到麻烦。我有一个提供编码字符串的外部源，但是当我尝试将其转换为要素并将其添加到矢量源时，出现以下错误：

Uncaught TypeError: Cannot read property 'ua' of undefined

这是我正在使用的当前代码：

vectorSource = new ol.source.Vector();
var layers = [
    new ol.layer.Tile({
        name: "SKL Tile Server",
        source: new ol.source.OSM({
            url: "https://placeholder/osm/{z}/{x}/{y}.png",
            crossOrigin: null
        })
    }),
    new ol.layer.Vector({
        name: "polylines",
        source: vectorSource
    })
];

map = new ol.Map({
    layers: layers,
    target: 'report_map',
    view: new ol.View({
        center: ol.proj.transform(
            [-118.014670, 45.35724], 'EPSG:4326', 'EPSG:900913'),
        zoom: 10
    })
})

var addPolylineToMap = function (encoded_line, line_style) {

    var line = new ol.format.Polyline().readGeometry({
        source: encoded_line,
        options: {
            dataProjection: …

我想使用Jquery隐藏滚动条.任何人都可以帮助我吗？

$
    ::-webkit-scrollbar { 
    display: none; 
}

这适用于Chrome,但我希望我的滚动隐藏所有浏览器,我该怎么做？
