I have a web project developed in Flex which I have to make work standalone using AIR.
I created Air project and loaded the web application using flash.html.HTMLLoader.
The content is loading fine and working.
There are few buttons which open different links using javascript functions window.open.
The links are not opening. The javascript function is getting called using ExternalInterface and I placed alerts in that which is displaying.
The function contains simple window.open
window.open("http://www.google.co.in","Google");
I tried several solutions mentioned but none of them are working.

http://cookbooks.adobe.com/index.cfm?event=showdetails&postId=9243
I even tried loading a simple page in HTMLLoader component with window.open method still it is not working. On button click only alert is working but window.open is not opening the link.
<html>
<head>
<title>Test</title>
<body scroll="no">
<input type="button" value="Click" onClick="window.open('http://www.google.co.in');">
</body>
</html>
Could some one help me please
This is a radical suggestion that may or may not work, but I think it's worth a try.
Override the window.open method itself
As before, wait until the Event.COMPLETE is fired, then take it from there:
var html:HTMLLoader = new HTMLLoader();
var urlReq:URLRequest = new URLRequest("whatever.html");
var oldWindowOpen:Object; // save it, just in case
html.load(urlReq);
html.addEventListener(Event.COMPLETE,
function (event:Event):void {
oldWindowOpen = html.window.open;
html.window.open = asWindowOpen;
});
function asWindowOpen(href:String, name:String="_blank", specs:Object=null, replace:Object=null):void {
var urlReq = new air.URLRequest(href);
air.navigateToURL(urlReq);
}
You should probably fill out some of the function to handle the other inputs as specified in the W3Schools Reference for Window open() Method. You may have to (or want to) change all the parameter types to Object, just to be safe, since, unlike ExternalInterface interactions, the JavaScript-ActionScript types are not automatically typecast across the AIR-WebKit exchange.
The AIR Webkit environment is quite restrictive in its support for the window.open method. See Adobe documentation on Restrictions on calling the JavaScript window.open() method.
The easiest way to deal with this is just let the system's default browser open the links. Adobe documents this very question, and shows how you can pop open url's from within AIR:
var url = "http://www.adobe.com";
var urlReq = new air.URLRequest(url);
air.navigateToURL(urlReq);
Generalizing this:
function openExternalLink(href:String):void {
var urlReq = new air.URLRequest(href);
air.navigateToURL(urlReq);
}
One option: Assuming you're running jQuery on the page, you could have all the links open externally as so:
var html:HTMLLoader = new HTMLLoader();
var urlReq:URLRequest = new URLRequest("whatever.html");
html.load(urlReq);
html.addEventListener(Event.COMPLETE,
function completeHandler(event:Event):void {
html.window.jQuery('a').click(clickHandler);
});
function clickHandler( e:Object ):void {
if (e.target && e.target.href) {
openExternalLink(e.target.href);
}
e.preventDefault();
}
For more on handling DOM Events in ActionScript, see the relevant Adobe Documentation.
None of that is tested, but hopefully it gives a rough outline.
Otherwise, if you are trying to do something fancy, like pop up AIR windows with HTMLLoader frames in them, I did find one blog post discussing that: Opening links in AIR’s HTML loader

I'm doing the frontend on my clients website and have come across a strange issue. On certain pages (maybe 5% of the total pages on the site), the simple hamburger icon javascript doesn't function at all.
Here is the JS (which, again, works on 95% of the pages):
const userBox = document.querySelector(".wdgt-user-box");
const userBtn = document.querySelector(".wdgt-login");
function toggleUserBox() {
if (userBox.style.display === "block") {
userBox.style.display = "none";
}
else {
userBox.style.display = "block";
}
}
userBtn.addEventListener("click", toggleUserBox);
Some things to rule out:
Z-index is not an issue. I can click on the icon (I tried adding an href and it worked).
The HTML and JS (and how the JS is linked) is exactly the same on all pages. The JS is included at the bottom of the HTML in all cases
The queryselector appears to be working in all cases when inspecting with Chrome dev tools
The one difference I noticed when setting up breakpoints is that when hovering over "toggleUserBox" on the pages where it doesn't work, Arguments: null. Here is the difference between the two:
Of course, please let me know if there is more useful info I can find. I'm new to Chrome dev tools.
Since you are using a class as the query selector, you could try checking if there is more than one object with the same class name on the page
I have a problem I would say stupid with html and javascript, a simple function that should make me visible and invisible a div crashes the html making it empty!
<button onclick="open()">Modifica</button>
js:
var x = document.getElementById ("joseph");
if (x.hidden == false) {
x.hidden = true;
} else {
x.hidden = false;
}
before:
after:
You don't have to write pre-defined methods. It works same for all other tech stacks such as Mysql, PHP, etc.
Recommend using opens, not open if you insist to use the open word.
<button onclick="opens()">Modifica</button>
You've hit a variation of this problem.
When searching for a variable named open the browser finds document.open before it finds your open function.
document.open opens a new document for writing (with document.write) which erases the existing document.
window.open is also predefined, so making a new global function with that name is not advised.
As with the linked question: Use addEventListener instead of onclick attributes.
I am editing a plone page to open an Excel document on a specific sheet. I created two buttons to see if either would appear as actual buttons and use the JS function I reference. With this code the exact part of the page looks like the image below.
Why is only text showing instead of the button and why is the onclick attribute not working?
Note: I have changed to links to the spreadsheet for posting it on here but the link has been tested on other webpages
<script type="text/javascript">
function Open_Excel_File(path,sheet)
{
fso = new ActiveXObject("Scripting.FileSystemObject");
if (!fso.FileExists(path))
alert("Cannot open file.\nFile '" + path + "' doesn't exist.");
else
{
var myApp = new ActiveXObject("Excel.Application");
if (myApp != null)
{
myApp.visible = true;
Book = myApp.workbooks.open(path);
var excel_sheet = Book.Worksheets(sheet).Activate;
myApp.range(f_range).Select;
}
else {
alert ("Cannot open Excel application");
}
}
}
</script>
<div>
<button onclick='Open_Excel_File("file://///fs-01\Departments\Underwriting\Statistical%20Data%20and%20Medical%20Information\Statistics\Cancers\Cancer%20Statistics%\Cancer%20Statistics%.xlsx", "Vulvar Ca");'>Open File</button>
<input type="button" onclick="Open_Excel_File('file://///fs-01\deps\uw\stat%20Data%20and%20Medical%20Information\Statistics\Cancers\Cancer%20Statistics%202018\Cancer%20Statistics%.xlsx', 'VCA');'>OPEN FILE</input>
</div>
your onclick value is not a function, it is the result of a function call. Try to change that to onclick="Open_Excel_File"; You'll have to provide the file path at some point
Accessing file system from browser is super restricted for security matters, the only way I see fit is to have a file input and using what user provides
Also Plone filter out a bounce of potential "nasty" tags through a specific configurable tool.
It seems to me that you have injected the in the source HTML of a Page (document) type.
If so, you will see in your browser that in, the page source code, the script tag has been totally stripped away.
So,
a correct way to inject some js in your page, is to load it as portal_javascript resource (plone<=4) or in resource_registry (plone>=5).
tha nasty way is to access, in the ZMI, at https://yourseite:8080/Plone/portal_transforms/safe_html/ and configure it to accept script tags inside a document (all document in your site actually).
If this answer does not satisfy you try to ask in the official community:

hth,

background:
i have developed and maintain and a web based sales system using classic asp, javascript and sql server for internal use. to minimise my workload I restrict access to system so that only IE and Chrome browsers can be used.
problem
following latest chrome upgrade (Version 34.0.1847.116), routines that have been working perfectly are no longer working in chrome. IE is fine.
overview
i use parent to call child window. search for data in child, then return variables back to parent, which closes child, processes variables and updates parent form. I use this in lots of screens within the system and i find it provides a neat and intuitive UI.
However, from what I have read, Google Chrome has now restricted this functionality and there are no workarounds. It is such a useful function, I wanted to ask who uses pop up windows in this way and what solutions are there? Thanks so much in advance for your advice.
code
parent: calls new child window:
Add Customer
function upload(){
....
newWindow2 = window.open(newWindow2Ref, "custWin", features);
}
child: pop up to search and find customer and then passes back variable (custId) to opener giving field dummy1 the focus
opener.document.star.dummy1[<%=passedptr%>].value = "<%=custId%>";
opener.document.star.dummy1[<%=passedptr%>].focus();
parent: dummy 1 input gains focus and calls guestChanged function
<input name="dummy1" value="" type="readonly" onFocus="javascript: guestChanged(<%=nameCounter%>)" style="width:1px; height:1px; border:0">
function guestChanged(custPtr) {
if (newWindow2 && !newWindow2.closed) {
newWindow2.close();
counter = document.star.counter.value*1;
dummy1 = document.star.dummy1[0].value;
errorFlag = false;
...etc.
As I say, this is working perfectly in IE and until yesterday in Chrome :(
I hope I have explained the circumstances sufficiently well.
Thank you for taking the time to read this.
answered my own question with a shove in the right direction from #lankymart (thanks)
posted in case of interest to anyone running into same issue
parent:
<input name="passedGuestId" id="passedGuestId" onFocus="javascript: guestChanged(<%=nameCounter%>)">
<input type=button onclick="javascript:openwindow(0)" value="Add Customer">
<script language="javascript">
function openwindow(ptr) {
newWindow2Ref = "www.child.asp";
window.open(newWindow2Ref,"_blank","height=600,width=600,status=yes,toolbar=no,menubar=no,location=no")
}
</script>
child:
in my case, search on form in classic asp then run js, which closes window and returns value
<SCRIPT LANGUAGE="JavaScript">
<!--
window.opener.document.getElementById('passedGuestId').value="<%=custId%>"
window.opener.document.getElementById('passedGuestId').focus();
window.close()
// -->
</script>
parent
on return, input passedGuestId gets focus and calls guestChanged() Js to process the information returned
function guestChanged(custPtr) {
counter = document.star.counter.value*1;
dummy1 = document.star.passedGuestId.value;
errorFlag = false;
etc...
I'm using plupload to client scaling of pictures before they are uploaded. I like the feature that it gracefully falls back to html4 if the user doesn't have flash, silverlight etc engines installed.
I want to be able to start the upload when the user clicks certain elements on the page and i want to handle the events (sometimes stopping a file dialog from opening). In fact i'd like to pop open the file dialog using javascript.
Ok, so HTML4 (or rather the browser, except chrome :P) won't let me do this, unless the user clicks a browse-button (or an overlay covering a browse-button), so when i get the fallback to HTML4 i'll accept that i can't do it, but most users will have flash or silverlight installed and they do not have this restriction. So my question is this:
How do i trigger the file open dialog in plupload (keeping in mind i only need the flash and silverlight engines to do this).
The former solutions not worked on iPhones with plupload 2.1.2.
The following code did the trick (jquery needed):
$("#id_of_the_second_button").click(function() {
$('div.moxie-shim input[type=file]').trigger('click');
});
Fallback runtimes will become irrelevant as times goes by. This means that sooner or later, we'll be all using HTML5 runtime. In case that you are using HTML5 runtime, but don't use pluploadQueue(), this will work as well:
// Set up and initialise uploader
var uploader = new plupload.Uploader({
'runtimes' : 'html5',
'browse_button' : 'id_of_the_first_button'
// Other options
});
uploader.init();
// Hook in the second button
plupload.addEvent(document.getElementById('id_of_the_second_button'), 'click', function(e) {
var input = document.getElementById(uploader.id + '_html5');
if (input && !input.disabled) {
input.click();
} // if
e.preventDefault();
});
If someone is searching for the HTML5 solution, here it is:
var up= $('#uploader').pluploadQueue();
if (up.features.triggerDialog) {
plupload.addEvent(document.getElementById('idOtherButton'), 'click', function(e) {
var input = document.getElementById(up.id + '_html5');
if (input && !input.disabled) { // for some reason FF (up to 8.0.1 so far) lets to click disabled input[type=file]
input.click();
}
e.preventDefault();
});
}
Ok. It doesn't seem possible to do this, so unless someone implements event handles for the silverlight and flash components i'm out of luck
I read your problem.
I found some articles that may help to figure this out. check them. It may help...!

#Per Hornshøj-Schierbeck
After uploader has been init. It take few time to render input file to select. So you need to wait like below:
this.uploader.init();
var task = new Ext.util.DelayedTask(function () {
var inputArray = $('div.moxie-shim input[type=file]');
var input = inputArray.length > 1 ? inputArray[inputArray.length - 1] :
inputArray[0];
$(input).trigger('click');
});
task.delay(100);
The code in javascript is similar. Worked for me with plupload 2.3.6
Hop this help!
