Question

我使用以下javascript来处理我的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，为我提供事件处理的可能性）

所以，除了一页之外，任何事情都很好：online.rsb.ru

UIWebView向我显示空白页

我开始用curl分析那个页面，那就是我得到的东西：

获取url online.rsb.ru

<html>
 <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可能与下一行代码冲突：

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

或

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

（问题取决于我的javascript，如果我删除stringByEvaluatingJavaScriptFromString:页面加载的电话就好了）

有人可以给我建议，我该如何避免这种冲突？谢谢！

问题解决了：

我已经取代了window.location = url的执行;在我的脚本中使用以下代码

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

HTTP-EQUIV =“REFRESH”与window.location = url冲突
