I'm using mootools-core-1.4.5.js in a Windows 8 Metro JavaScript App, and when a try to Create App Packages, I got an error at the Validation step :
mootools-core-1.4.5.js has JavaScript syntax or other problems.
I found a solution that works for me.
I used mootools-core-1.4.5-full-compat.js and I commented out these lines :
//Browser.exec = function(text){
// if (!text) return text;
// if (window.execScript){
// window.execScript(text);
// } else {
// var script = document.createElement('script');
// script.setAttribute('type', 'text/javascript');
// script.text = text;
// document.head.appendChild(script);
// document.head.removeChild(script);
// }
// return text;
//};
//String.implement('stripScripts', function(exec){
// var scripts = '';
// var text = this.replace(/<script[^>]*>([\s\S]*?)<\/script>/gi, function(all, code){
// scripts += code + '\n';
// return '';
// });
// if (exec === true) Browser.exec(scripts);
// else if (typeOf(exec) == 'function') exec(scripts, text);
// return text;
//});

I use Xamarin-CrossDownloadManager (https://github.com/SimonSimCity/Xamarin-CrossDownloadManager) and I need waiting for download a file. I have this code:
private static async Task<bool> FileDownloadedTest(string LinkToFile, string PathFile)
{
var downloadManager = CrossDownloadManager.Current;
CrossDownloadManager.Current.PathNameForDownloadedFile = new System.Func<IDownloadFile, string>(file => {
return PathFile;
});
{
await DeleteFile(PathFile);
var file = downloadManager.CreateDownloadFile(LinkToFile);
await Task.Run(() => downloadManager.Start(file, true)); //why this not wait???
}
bool FileExist = await IsFileExist(PathFile);
return FileExist;
}
Why it not wait for finish download action? How to do it?
On library site they wrote, that I can watch the IDownloadManager.Queue to get information when the file is downloaded. But, I don't know how to use this in my method... Can you help me?
PS: Sorry for my english, I'm still learning it ;)
With that library, there is no callback or event published for when a file is finished downloading, but you can do a simple check and wait some more loop.
await Task.Run(async () =>
{
var downloadManager = CrossDownloadManager.Current;
var file = downloadManager.CreateDownloadFile(someFileBasedUrl);
downloadManager.Start(file);
bool isDownloading = true;
while (isDownloading)
{
await Task.Delay(10 * 1000);
isDownloading = IsDownloading(file);
}
});
The IsDownloading method:
bool IsDownloading(IDownloadFile file)
{
if (file == null) return false;
switch (file.Status)
{
case DownloadFileStatus.INITIALIZED:
case DownloadFileStatus.PAUSED:
case DownloadFileStatus.PENDING:
case DownloadFileStatus.RUNNING:
return true;
case DownloadFileStatus.COMPLETED:
case DownloadFileStatus.CANCELED:
case DownloadFileStatus.FAILED:
return false;
default:
throw new ArgumentOutOfRangeException();
}
}
Re: https://github.com/SimonSimCity/Xamarin-CrossDownloadManager/blob/develop/Sample/DownloadExample/Downloader.cs#L46
I don't know why IDownloadFile.Status = COMPLETED not working, but i found solve problem:
await Task.Run(() =>
{
var downloadManager = CrossDownloadManager.Current;
var file = downloadManager.CreateDownloadFile(LinkToFile);
downloadManager.Start(file);
while (file.Status == DownloadFileStatus.INITIALIZED)
{
while (file.TotalBytesExpected > file.TotalBytesWritten)
{
Debug.WriteLine(file.Status);
}
}
});
Somebody know why DownloadFileStatus.INITIALIZED working, but DownloadFileStatus.COMPLETED not?
SushiHangover's answer above worked great, and I combined it with ACR User Dialog's package (https://github.com/aritchie/userdialogs) to show a nice loading progress screen to the user while waiting for the download to complete. This works nicely on Android (I couldn't test iOS yet).
...
var downloadManager = CrossDownloadManager.Current;
var fileToDownload = downloadManager.CreateDownloadFile(args.Url);
downloadManager.Start(fileToDownload, true);
args.Cancel = true;
UserDialogs.Instance.Progress("Downloading").Show();
bool isDownloading = true;
while (isDownloading)
{
await Task.Delay(100);
if (fileToDownload.TotalBytesExpected > 0)
{
UserDialogs.Instance.Progress().PercentComplete = (int)(fileToDownload.TotalBytesWritten / fileToDownload.TotalBytesExpected * 100);
Console.WriteLine(("DOWNLOAD PROGRESS: " + fileToDownload.TotalBytesWritten / fileToDownload.TotalBytesExpected * 100).ToString() + "%");
}
isDownloading = IsDownloading(fileToDownload);
}
UserDialogs.Instance.Progress().Hide();
//Below code opens the download location after download has completed.
Intent intent = new Intent(DownloadManager.ActionViewDownloads);
intent.AddFlags(ActivityFlags.NewTask);
Android.App.Application.Context.StartActivity(intent);
return;
}
}
}
bool IsDownloading(IDownloadFile file)
{
if (file == null) return false;
switch (file.Status)
{
case DownloadFileStatus.INITIALIZED:
case DownloadFileStatus.PAUSED:
case DownloadFileStatus.PENDING:
case DownloadFileStatus.RUNNING:
return true;
case DownloadFileStatus.COMPLETED:
case DownloadFileStatus.CANCELED:
case DownloadFileStatus.FAILED:
return false;
default:
throw new ArgumentOutOfRangeException();
}
}
I do not know what I am talking about here I go.
On some pages it filters them and others like Youtube comments don't work.
What code needs to change in order for it to work in these sites?
// ==UserScript==
// #name profanity_filter
// #namespace localhost
// #description Profanity filter
// #include *
// #version 1
// #grant none
// ==/UserScript==
function recursiveFindTextNodes(ele) {
var result = [];
result = findTextNodes(ele,result);
return result;
}
function findTextNodes(current,result) {
for(var i = 0; i < current.childNodes.length; i++) {
var child = current.childNodes[i];
if(child.nodeType == 3) {
result.push(child);
}
else {
result = findTextNodes(child,result);
}
}
return result;
}
var l = recursiveFindTextNodes(document.body);
for(var i = 0; i < l.length; i++) {
var t = l[i].nodeValue;
t = t.replace(/badword1|badword2|badword3/gi, "****");
t = t.replace(/badword4/gi, "******");
t = t.replace(/badword5|badword6|badword7/gi, "*****");
t = t.replace(/badword8/gi, "******");
l[i].nodeValue = t;
}
* Replaced profanity in code to badword
Youtube comments are loaded asynchronously, quite a long time after the page has loaded (userscripts by default are executed at DOMContentLoaded event), so you need to wrap your code as a callback function of waitForKeyElements with a selector for the comments container or MutationObserver or setInterval.
replaceNodes(); // process the page
waitForKeyElements('.comment-text-content', replaceNodes);
function replaceNodes() {
..............
..............
}
Using setInterval instead of waitForKeyElements:
replaceNodes(); // process the page
var interval = setInterval(function() {
if (document.querySelector('.comment-text-content')) {
clearInterval(interval);
replaceNodes();
}
}, 100);
function replaceNodes() {
..............
..............
}
P.S. Don't blindly assign the value to the node, check first if it has changed to avoid layout recalculations:
if (l[i].nodeValue != t) {
l[i].nodeValue = t;
}
if i run my code in mozilla firefox after i click scan in UI select source window is opened and then it crashed.
bt the same code if i run on chrome it scan the image in the scanner after that if i click the scan on the new window it scan properly and crashed during file transfer and chrome tell a error message "a plugin (shockwave flash) isnt responding "

I try to unregister stylesheet:
try {
var StyleService = Cc["#mozilla.org/content/style-sheet-service;1"].getService(Ci.nsIStyleSheetService);
StyleService.unregisterSheet(url, StyleService.USER_SHEET);
} catch (e){
console.log(e);
}
var isRegistered = StyleService.sheetRegistered(url, StyleService.USER_SHEET);
if (isRegistered) {
console.log("styleSheet unregister check is failed url:" + url.path);
}
One stylesheet i generate Services.io.newURI("data:text/css,"+ encodeURIComponent(content), null, null);
And it unregisters fine. But another file located on ProfD directory fails on isRegistered check.
var styleFile = FileUtils.getFile(FS.ProfileName, [FS.DirName, this.CSS_FILE_PATH]);
this.injectCssUrl = IoService.newFileURI(styleFile).QueryInterface(Ci.nsIFileURL);
Why it unregister?
var sss = Components.classes['#mozilla.org/content/style-sheet-service;1'].getService(Components.interfaces.nsIStyleSheetService);
var ios = Components.classes['#mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService);
try {
sss.unregisterSheet(cssUri, sss.USER_SHEET);
} catch (ex) {}
var css = 'setting .preferences-alignment{ display:flex; flex-direction:row-reverse; align-items:center; }';
//var cssEnc = 'data:text/css;base64,' + window.btoa(css);
var cssEnc = encodeURIComponent(css);
var cssUri = makeURI('data:text/css,' + cssEnc);
sss.loadAndRegisterSheet(cssUri, sss.USER_SHEET);
if you want to use a file then something like
var appliedURI;
function startup(aData, aReason) {
var path = aData.resourceURI.spec + 'no_icon.css'; //or in your case styleFile.path
appliedURI = Services.io.newURI(path, null, null);
sss.loadAndRegisterSheet(appliedURI, sss.USER_SHEET);
}
function shutdown(aData, aReason) {
if (aReason == APP_SHUTDOWN) return;
sss.unregisterSheet(appliedURI, sss.USER_SHEET);
}
My problem was that i register the same style several times. After i unregister style each time before register again all works normaly
I have a problem with nicEdit link creation tool in IE and Firefox.
In general, I think the problem is related to the execCommand in IE and FireFox. It seems document doesn't get updated after execCommand executes.
This is an example of my problem with nicEdit create link command.
if(!this.ln) {
var tmp = 'javascript:nicTemp();';
this.ne.nicCommand("createlink",tmp);
this.ln = this.findElm('A','href',tmp);
// set the link text to the title or the url if there is no text selected
alert(this.ln);
if (this.ln.innerHTML == tmp) {
this.ln.innerHTML = this.inputs['title'].value || url;
};
}
The code above is called when no text is selected, Chrome returns 'javascript:nicTemp()' for the alert(this.ln), while IE 8 and Firefox return 'undefined', so the next line after the alert encounters an error in IE and Firefox.
it seems findElem can't find the newly created link by nicCommand which in turn calls execCommand
I had similar problems when I try to find and modify tags created with execCommand, it seems the dom isn't updated to include them.
Am I right? How can I solve this problem? how can I force the document to be updated ....
please help
my trick for nicEdit, in the situation when no text is selected, is to paste the title given via the Add Link form into the document and select it, then the rest code works as it works when a text is selected.
I used the function pasteHtmlAtCaret described in the following link to paste the title
Insert html at caret in a contenteditable div
this.removePane();
var url = this.inputs.href.value;
var selected = getSelected();
var B= 'javascript:nicTemp()';
if (selected == '')
{
var B = url;
pasteHtmlAtCaret(this.inputs['title'].value || url,true);
}
if(!this.ln){
this.inputs.title.value;this.ne.nicCommand("createlink",B);
this.ln=this.findElm("A","href",B)
}
the getSelected is also a simple function as below
function getSelected()
{
if (document.selection)
return document.selection.createRange().text;
else
return window.getSelection();
}
Ahmad, just use this variation of the "submit" function to avoid the "insert/edit" problem with the link, it worked for me:
submit : function(e) {
var url = this.inputs['href'].value;
if(url == "http://" || url == "") {
alert("Introduce una URL valida para crear el Link.");
return false;
}
this.removePane();
if(!this.ln) {
//**************** YOUR CHANGE WITH A BIT OF VARIATION **************
var selected = this.getSelected();
var tmp = 'javascript:void(0)';
if (selected == '') {
tmp = url;
this.pasteHtmlAtCaret(this.inputs['title'].value || tmp, true);
}
//**************** END OF YOUR CHANGE WITH A BIT OF VARIATION **************
this.ne.nicCommand("createlink",tmp);
this.ln = this.findElm('A','href',tmp);
// set the link text to the title or the url if there is no text selected
if (this.ln.innerHTML == tmp) {
this.ln.innerHTML = this.inputs['title'].value || url;
};
}
if(this.ln) {
var oldTitle = this.ln.title;
this.ln.setAttributes({
href: this.inputs['href'].value,
title: this.inputs['title'].value,
target: '_blank'
});
// set the link text to the title or the url if the old text was the old title
if (this.ln.innerHTML == oldTitle) {
this.ln.innerHTML = this.inputs['title'].value || this.inputs['href'].value;
};
}
}
this.removePane();
var url = this.inputs['href'].value;
var selected = getSelected();
var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);
var tmp = "";
if(isChrome == true){
tmp=url;
}
else{tmp='javascript:nicTemp()'}
if (selected == '' && isChrome == false)
{
pasteHtmlAtCaret(this.inputs['title'].value || url,true);
}
if (!this.ln) {
//var tmp = this.inputs['title'].value == "" ? this.inputs['href'].value : this.inputs['title'].value;
this.ne.nicCommand("createlink", tmp);
this.ln = this.findElm('A', 'href', tmp);
}
function getSelected()
{
if (document.selection)
return document.selection.createRange().text;
else
return window.getSelection();
}
function pasteHtmlAtCaret(html) {
var sel, range;
if (window.getSelection) {
// IE9 and non-IE
sel = window.getSelection();

range.collapse(true);

}
}
} else if (document.selection && document.selection.type != "Control") {
// IE < 9
document.selection.createRange().pasteHTML(html);
}
