我今天找到了一个可以再web页面上使用JS+FLASH来录音的开源代码——flashwavrecordr
但是我从github下载的Demo，却不能正确运行，后来我发现主要是Recorder 中的 recorder为空
后来我查了一下代码，recorder 这个属性是从一个事件里面进行处理的
[code=javascript]
window.fwr_event_handler = function fwr_event_handler() {
$('#status').text("Last recorder event: " + arguments[0]);
var name, $controls;
switch (arguments[0]) {
case "ready":
var width = parseInt(arguments[1]);
var height = parseInt(arguments[2]);
FWRecorder.uploadFormId = "#uploadForm";
FWRecorder.uploadFieldName = "upload_file[filename]";
FWRecorder.connect("recorderApp", 0);
FWRecorder.recorderOriginalWidth = width;
FWRecorder.recorderOriginalHeight = height;
$('.save_button').css({'width': width, 'height': height});
break;
case "no_microphone_found":
break;
case "microphone_user_request":
recorderEl().addClass("floating");
FWRecorder.showPermissionWindow();
break;
case "microphone_connected":
FWRecorder.isReady = true;
$uploadStatus.css({'color': '#000'});
break;
case "permission_panel_closed":
FWRecorder.defaultSize();
recorderEl().removeClass("floating");
break;
case "microphone_activity":
$('#activity_level').text(arguments[1]);
break;
case "recording":
name = arguments[1];
$controls = controlsEl(name);
FWRecorder.hide();
setControlsClass($controls, CLASS_RECORDING);
break;
case "recording_stopped":
name = arguments[1];
$controls = controlsEl(name);
var duration = arguments[2];
FWRecorder.show();
setControlsClass($controls, CLASS_PLAYBACK_READY);
$('#duration').text(duration.toFixed(4) + " seconds");
break;
case "microphone_level":
$level.css({width: arguments[1] * 50 + '%'});
break;
case "observing_level":
$showLevelButton.hide();
$hideLevelButton.show();
break;
case "observing_level_stopped":
$showLevelButton.show();
$hideLevelButton.hide();
$level.css({width: 0});
break;
case "playing":
name = arguments[1];
$controls = controlsEl(name);
setControlsClass($controls, CLASS_PLAYING);
break;
case "playback_started":
name = arguments[1];
var latency = arguments[2];
break;
case "stopped":
name = arguments[1];
$controls = controlsEl(name);
setControlsClass($controls, CLASS_PLAYBACK_READY);
break;
case "playing_paused":
name = arguments[1];
$controls = controlsEl(name);
setControlsClass($controls, CLASS_PLAYBACK_PAUSED);
break;
case "save_pressed":
FWRecorder.updateForm();
break;
case "saving":
name = arguments[1];
break;
case "saved":
name = arguments[1];
var data = $.parseJSON(arguments[2]);
if (data.saved) {
$('#upload_status').css({'color': '#0F0'}).text(name + " was saved");
} else {
$('#upload_status').css({'color': '#F00'}).text(name + " was not saved");
}
break;
case "save_failed":
name = arguments[1];
var errorMessage = arguments[2];
$uploadStatus.css({'color': '#F00'}).text(name + " failed: " + errorMessage);
break;
case "save_progress":
name = arguments[1];
var bytesLoaded = arguments[2];
var bytesTotal = arguments[3];
$uploadStatus.css({'color': '#000'}).text(name + " progress: " + bytesLoaded + " / " + bytesTotal);
break;
}
};
[/code]
我也添加了断点调试过，证明我操作的时候没有运行过这个代码。
请问有谁用过这个东西的，能给我解答一下
