HTTP-EQUIV="REFRESH" conflict with window.location

HTTP-EQUIV="REFRESH" conflict with window.location = url

本文关键字：quot window location with conflict HTTP-EQUIV REFRESH      更新时间：2023-09-26

我使用以下javascript来处理UIWebView中的"页面加载"事件：

(function() {
if (typeof Browser == "undefined") {
    Browser = {};
}
var onWindowLoaded = function() {
    Browser.commands.sendCommand("page-loaded");
};
if (document.readyState === "complete") {
    onWindowLoaded();
}
else {
    window.addEventListener('loaded', function(event) {
                            onWindowLoaded();
                            });
}
})();

我用stringByEvaluatingJavaScriptFromString:加载它

sendCommand 函数调用window.location = url;（具有特定方案的 url，使我有可能处理事件）

所以一切都很好，除了一页：online.rsb.ru

UIWebView显示空白页

我

开始用curl分析那个页面，我得到的是：

获取网址 online.rsb.ru

获取网址 https://online.rsb.ru/hb/

 <head>
  <script type="text/javascript">
 window.location = "faces/system/login/rslogin.jsp?credit=false"
 </script>
 </head>
</html>

所以，我发现我的javascript可能会与下一行代码冲突：

<meta HTTP-EQUIV="REFRESH" content="0; url=https://online.rsb.ru/hb/">

或与 

window.location = "faces/system/login/rslogin.jsp?credit=false"

（问题取决于我的 JavaScript，如果我删除stringByEvaluatingJavaScriptFromString:页面加载正常的调用）

有人可以给我建议，我怎样才能避免这种冲突？谢谢！

问题已解决：

我已经在我的脚本中替换了 window.location = url; 的执行使用以下代码

 function sendURLToUIWebView(url) {
    var iframe = document.createElement("IFRAME");
    iframe.setAttribute("src", url);
    document.documentElement.appendChild(iframe);
    iframe.parentNode.removeChild(iframe);
    iframe = null;
 }
