I have a function, with some unfamiliar code inside. This works, but I am trying to assign a button, or link to run this and normal javascript events will not work. The app is based on jquery, and jqueryui.
el.prototype.commands.mkdir = function() {
this.disableOnSearch = true;
this.updateOnSelect = false;
this.mime = 'directory';
this.prefix = 'untitled folder';
this.exec = $.proxy(this.fm.res('mixin', 'make'), this);
this.shortcuts = [{
pattern: 'ctrl+shift+n'}];
this.getstate = function() {
return !this._disabled && this.fm.cwd().write ? 0 : -1;
}
}
Does anyone have any ideas.
The above is code from elFinder, which is open-source and can be found on github. elFinder has a function/button ready for you for the create folder action. What else are you trying to achieve?

I have created a simple extension in autodesk forge.
The idea is that when I make a mouse-over event on a 3D object it has to show me the ID of the hovered object/sub-object my extension code runs like this.
AutodeskNamespace("Autodesk.ADN.Viewing.Extension");
Autodesk.ADN.Viewing.Extension.MouseEvent = function (viewer, options) {
Autodesk.Viewing.Extension.call(this, viewer, options);
var _self = this;
var _viewer = viewer;
var _selectedId = null;
//On Load of the exension function
_self.load = function () {
_viewer.addEventListener(
Autodesk.Viewing.MOUSE_OVER_EVENT,
_self.onMouseOver);
console.log("Autodesk.ADN.MouseEvent loaded");
return true;
};
//On unload of the exension function
_self.unload = function () {
_viewer.removeEventListener(
Autodesk.Viewing.MOUSE_OVER_EVENT,
_self.onMouseOver);
console.log("Autodesk.ADN.MouseEvent unloaded");
return true;
};
// Event function initialization
_self.onMouseOver = function (event) {
var dbId = event.dbIdArray[0];
if (typeof dbId !== 'undefined') {
_selectedId = dbId;
alert('ID: ' + _selectedId);
}
else _selectedId = null;
}
};
Autodesk.ADN.Viewing.Extension.MouseEvent.prototype =
Object.create(Autodesk.Viewing.Extension.prototype);
Autodesk.ADN.Viewing.Extension.MouseEvent.prototype.constructor =
Autodesk.ADN.Viewing.Extension.MouseEvent;
Autodesk.Viewing.theExtensionManager.registerExtension(
'Autodesk.ADN.Viewing.Extension.MouseEvent',
Autodesk.ADN.Viewing.Extension.MouseEvent);
but the onMouseOver function is not working, can anyone please help me? thanks in advance.
PS: I have included the extensions in the script tags and the extension is loaded likewise.
oViewer.loadExtension('Autodesk.ADN.Viewing.Extension.MouseEvent');
I also get a confirmation from the console that the extension is loaded successfully.
There is no such event as Autodesk.Viewing.MOUSE_OVER_EVENT ... did you just made that up or you got it from some - apparently incorrect - source?
The way to handle that would be to use a viewer tool (see that post for details), then in handleMouseMove callback, do the following:
handleMouseMove (event) {
var hitTest = _self.viewer.clientToWorld(
event.canvasX,
event.canvasY,
true)
if (hitTest) {
console.log(hitTest)
}
}
Here is another post I wrote about viewer events, it is a bit old, so there are a couple more now but can give you a good starting point.
I written this code:
var fi = self.find('.file');
fi.on('change', function() {
if(fi.prop('files').length === 1) {
var file = fi.prop('files')[0],
name = file.name,
ext = name.split('.').pop().toLowerCase(),
size = (file.size / 1048576).toFixed(2),
type = file.type;
if($.inArray(ext, ['jpg', 'png', 'gif']) == -1) {
return false;
}
if($.inArray(type, ['image/jpeg', 'image/png', 'image/gif']) == -1) {
return false;
}
if(size > 1.2) {
return false;
}
ajax(createData(file));
return false;
}
return false;
});
I am allowing to upload only 1 file at the time ( from html side, js side and php side of view ), but with this script if user selects bigger size file, lets say 2+ MB and he is really fast clicker he can select another file and it creates second event and both files are being uploaded to the server which causes chaos and problems. Also i will be implementing drag and drop upload option so as a beginner javascript coder im asking the community if there is a way to:
Prevent from triggering script while file is being already uploaded ( i dont mean methods like hide input or diable it or take off event listener for a while, i mean method that detects if event is running and prevent executing script ). I tried things like default prevent or stop propagation but these dont work obviously.
Adding a button that will cancel on going script ( meaning stop file uploading and "clean it up" so user can safetly try again )
Thank you in advance for all your hints and guidance ;)
I worked on this recently for one of my side projects. Here's a code sample:
var fileReader = new FileReader();
var fileFilter = /^(?:image\/bmp|image\/cis\-cod|image\/gif|image\/ief|image\/jpeg|image\/jpeg|image\/jpeg|image\/pipeg|image\/png|image\/svg\+xml|image\/tiff|image\/x\-cmu\-raster|image\/x\-cmx|image\/x\-icon|image\/x\-portable\-anymap|image\/x\-portable\-bitmap|image\/x\-portable\-graymap|image\/x\-portable\-pixmap|image\/x\-rgb|image\/x\-xbitmap|image\/x\-xpixmap|image\/x\-xwindowdump)$/i;
var imageObject = { valid: false };
fileReader.onload = function (fileReaderEvent) {
imageObject.data = fileReaderEvent.target.result;
};
var loadImage = function() {
if (element[0].files.length === 0) {
return;
}
var file = element[0].files[0];
imageObject.filename = file.name;
if (!fileFilter.test(file.type)) {
imageObject.error = 'You must select a valid image!';
imageObject.valid = false;
return;
}else{
imageObject.error = '';
imageObject.valid = true;
}
fileReader.readAsDataURL(file);
};
element.on('change', loadImage);
}
This was from an AngularJS project so I've removed all the angular components but it should be pretty easy to add in the necessary JQuery code.
First Question here, too! Yay! Just moved this from AskUbuntu.
I am just about to finish a little private project for gaining some experience where i try to change the app layout so it works as a normal website (on Jimdo, so it was quite of a challenge first) without much JavaScript required but is fully functional on mobile view.
Since Jimdo serves naturally only the actual site, I had to implement an
if (activeTab.getAttribute('jimdo-target') != null)
location.href = activeTab.getAttribute('jimdo-target');
redirect into the __doSelectTab() function in tabs.js . (In js I took the values from the jimdo menu string to build the TABS menu with this link attribute)
Now everything works fine exept at page load the first tab is selected. I got it to set the .active and .inactive classes right easily, but it is not shifted to the left.
So my next idea is to let it initialize as always and then send a command to change to the current tab.
Do you have any idea how to manage this? I couldn't because of the this.thisandthat element I apparently don't really understand...
Most of you answering have the toolkit and the whole code, but I am listing the select function part of the tabs.js:
__doSelectTab: function(tabElement, forcedSelection) {
if ( ! tabElement)
return;
if (tabElement.getAttribute("data-role") !== 'tabitem')
return;
if (forcedSelection ||
(Array.prototype.slice.call(tabElement.classList)).indexOf('inactive') > -1) {
window.clearTimeout(t2);
activeTab = this._tabs.querySelector('[data-role="tabitem"].active');
offsetX = this.offsetLeft;
this._tabs.style['-webkit-transition-duration'] = '.3s';
this._tabs.style.webkitTransform = 'translate3d(-' + offsetX + 'px,0,0)';
this.__updateActiveTab(tabElement, activeTab);
if (activeTab.getAttribute('jimdo-target') != null)
location.href = activeTab.getAttribute('jimdo-target');
[].forEach.call(this._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)'), function (e) {
e.classList.remove('inactive');
});
var targetPageId = tabElement.getAttribute('data-page');
this.activate(targetPageId);
this.__dispatchTabChangedEvent(targetPageId);
} else {
[].forEach.call(this._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)'), function (el) {
el.classList.toggle('inactive');
});
var self = this;
t2 = window.setTimeout(function () {
var nonActiveTabs = self._tabs.querySelectorAll('[data-role="tabitem"]:not(.active)');
[].forEach.call(nonActiveTabs, function (el) {
el.classList.toggle('inactive');
});
}, 3000);
}
},
...and my app.js hasn't anything special:
var UI = new UbuntuUI();
document.addEventListener('deviceready', function() { console.log('device ready') }, true);
$(document).ready(function () {
recreate_jimdo_nav();
UI.init();
});
So meanwhile found a simple workaround, however I'd still like to know if there is another way. Eventually I noticed the __doSelectTab() function is the one that executes the click, so it does nothing but to show the other tab names when they are hidden first. so I added the global value
var jnavinitialized = false;
at the beginning of the tabs.js and run
var t = this;
setTimeout(function(){t.__doSelectTab(t._tabs.querySelector('[data-role="tabitem"].jnav-current'))}, 0);
setTimeout(function(){t.__doSelectTab(t._tabs.querySelector('[data-role="tabitem"].jnav-current'))}, 1);
setTimeout(function(){jnavinitialized = true;}, 10);
at the top of the __setupInitialTabVisibility() function. Then I changed the location.href command to
if (activeTab.getAttribute('jimdo-target') != null && jnavinitialized)
location.href = activeTab.getAttribute('jimdo-target');
And it works. But originally I searched for a way to change the tab on command, not to run the command for selecting twice. So if you know a better or cleaner way, you are welcome!
I'm developing a simple gadget for Windows 7 as a learning exercise.
I read in this article (under the subtopic Gadgets and Script) that to initialize the gadget, you should use document.onreadystatechange instead of events such as onLOad. I've seen it in the example project code I've looked through as well. This is what I came up with for my project.
document.onreadystatechange = function()
{
if(document.readyState == "complete")
{
System.Gadget.settingsUI = "settings.html"; //this line enables the settings UI
System.Gadget.onSettingsClosed = settingsClosed;
}
}
However when I use this snippet in my work, it doesn't work. The Options button in the gadget doesn't show up. If I use onLoad, it works. I have installed 2 gadgets. Each of them use these 2 methods. One use onLoad and the other use document.onreadystatechange. And both of them works!
Now I'm confused why it doesn't work with my gadget. Is there any important part I'm overlooking?
try something along these lines,
move your onsettingsclosed to a different event and call the function with it
document.onreadystatechange = function()
{
if(document.readyState=="complete")
{
var searchTags = System.Gadget.Settings.read("searchTags");
if(searchTags != "")
{
searchBox.value = searchTags;
}
}
}
System.Gadget.onSettingsClosing = function(event)
{
if (event.closeAction == event.Action.commit)
{
var searchTags = searchBox.value;
if(searchTags != "")
{
System.Gadget.Settings.write("searchTags", searchTags);
}
event.cancel = false;
}
}
I downloaded the File upload script called Simple Photo Manager.
Since I'm more familiar with jQuery functions I want to use them in combination with the already existing JS code from that script.
I basically want to hide the Delete button when it's clicked.
Why is the Delete button not being hidden after I click on it?
(Note: the JS files are correctly included into the HTML file)
Also, the delLink.removeChild and delLink.appendChild are useless here because it was originally intended for a Delete/Restore switch link, but I decided to go for a button instead.
Thanks a lot if you can help me.
The html code is:
<input type='button' id='deleteit' onClick="deleteLinkOnClick
(this, 'delFlag<?=$imgid?>')">
The JS code for creating that element when an image is uploaded is:
var image_del_link = par.createElement('input');
image_del_link.type = "button";
image_del_link.value = "Delete";
imgdiv.appendChild(image_del_link);
The function for the onclick is: (I tried to write the jQuery function at the bottom)
function deleteLinkOnClick(delLink, delFlag) {
var par = window.document;
var imgDiv = delLink.parentNode;
var image_hidden = delFlag == '' ? imgDiv.childNodes[2] : par.getElementById(delFlag);
if (image_hidden.value == '1') {
image_hidden.value = '0';
delLink.removeChild(delLink.childNodes[0]);
delLink.appendChild(par.createTextNode("Restore"));
delLink.style.color = '#FF0000';
}
else {
image_hidden.value = '1';
delLink.removeChild(delLink.childNodes[0]);
delLink.appendChild(par.createTextNode("Delete"));
delLink.style.color = '#64B004';
}
$(document).ready(function(){
$(image_del_link).click(function(){
$(this).hide();
});
});
}
Here it is.
$("#deleteit").click(function(){
$(this).hide();
})
Try :
$("#deleteit").live("click", function(){
$(this).hide();
});
