Question

我正在做一个 app子,当时,我正在利用 Java文把你带入“IDWebView”。我想公开/阅读/准备从javascript开始的一些事件的档案,然后希望在客观法典中使用这一档案。但我如何能够这样做? 我指的是我能够拯救和打开档案的地点。

我已经提交了一份名为“你”的档案,并将这一档案从客观的法典中删除。该网页成功开放。现在,我要开立案卷,每当它所描述的变化时写出一些东西,然后需要证明,最后是出于服从。请告诉我,我如何能够这样做。

<!DOCTYPE HTML>
<html>
<body>
<div id="player"></div>
<script>
    //Load player api asynchronously.
    var tag = document.createElement( script );
    tag.src = "http://www.youtube.com/player_api";
    var firstScriptTag = document.getElementsByTagName( script )[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    var done = false;
    var player;
    function onYouTubePlayerAPIReady() {
        player = new YT.Player( player , {
          height:  390 ,
          width:  640 ,
          videoId:  JW5meKfy3fY ,
          events: {
             onReady : onPlayerReady,
             onStateChange : onPlayerStateChange
          }
        });
    }
    function onPlayerReady(evt) {
        evt.target.playVideo();
    }
    function onPlayerStateChange(evt) {
        if (evt.data == YT.PlayerState.PLAYING && !done) { // NEED TO ADD FILE OPERATION HERE
            setTimeout(stopVideo, 6000);
            done = true;
        }
    }
    function stopVideo() {
        player.stopVideo();
    }
</script>
</body>
</html>

Answer 1

// Get file path
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString filePath = [documentsDirectory stringByAppendingPathComponent:filename];

// Read file contents
NSString *content = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

// Write file contents
[[content dataUsingEncoding:NSUTF8StringEncoding] writeToFile:filePath atomically:NO];

Answer 2

UIWebView is a sandbox, there is no chance to do this, javascript can not access file system directly, this is what i know. But you can do other thing. first: save state into window object;

such as window.state = "someting";

第二:按目标C改为国家;

NSString *state = [webView stringByEvaluatingJavaScriptFromString:@"window.state"];
