I'm trying to call a JS function from an SWF which is loaded inside an application tab. As a canvas FBML, the code is working correctly but in case of application tab it's not working.
AS3 Code:
protected function button1_clickHandler(event:MouseEvent):void
{
callFBJS(["insideFlex"])
}
protected function callFBJS(text:Array):void
{
var connection:LocalConnection = new LocalConnection();
var connectionName:String = loaderInfo.parameters.fb_local_connection;
if (connectionName)
{
logLbl.text = "Connection Name: " + connectionName;
connection.send(connectionName,"callFBJS","doSomething",text);
logLbl.text = logLbl.text + "\n" + "Method invoked";
}
}
JS Code:
<fb:fbjs-bridge/>
<fb:swf swfsrc="<SWF File>" imgsrc="http://www.easyhealth.org.uk/cmsimages/adobe_flash_1470_1470.jpg" height="655" width="760"/>
<script>
function doSomething(a)
{
console.log(a);
}
</script>
I spent a day solving this issue. You have to declare any FBJS function and call it by clicking on an HTML link. After you click, the FBJS-bridge-based calls will work. I don't understand how or why, but this solved the problem for me.

I'm trying to create a customized button to appear on a pop up which generates a dynamic link (a URL). I don't seem to be able to do this via the .setHTML because of the timing, can't bind a button to a function at runtime. So I thought I'd try the newish .setDOMContent
There's zero information online as to how this feature works. I'm wondering if anyone has an example of this where a button is added to the popup that can run a function and send data.
Here's my very poor attempt at setting this up.
This function creates the popup
function GameObjectPopup(myObject) {
var features = map.queryRenderedFeatures(myObject.point, {
layers: ['seed']
});
if (!features.length) {
return;
}
var feature = features[0];
// Populate the popup and set its coordinates
// based on the feature found.
var popup = new mapboxgl.Popup()
.setLngLat(feature.geometry.coordinates)
.setHTML(ClickedGameObject(feature))
.setDOMContent(ClickedGameObject2(feature))
.addTo(map);
};
This function adds the html via the .setHTML
function ClickedGameObject(feature){
console.log("clicked on button");
var html = '';
html += "<div id='mapboxgl-popup'>";
html += "<h2>" + feature.properties.title + "</h2>";
html += "<p>" + feature.properties.description + "</p>";
html += "<button class='content' id='btn-collectobj' value='Collect'>";
html += "</div>";
return html;
}
This function wants to add the DOM content via the .setDOMContent
function ClickedGameObject2(feature){
document.getElementById('btn-collectobj').addEventListener('click', function()
{
console.log("clicked a button");
AddGameObjectToInventory(feature.geometry.coordinates);
});
}
I'm trying to pipe the variable from features.geometry.coordinates into the function AddGameObjectToInventory()
the error I'm getting when clicking on an object (so as popup is being generated)
Uncaught TypeError: Cannot read property 'addEventListener' of null
Popup#setHTML takes a string that represents some HTML content:
var str = "<h1>Hello, World!</h1>"
popup.setHTML(str);
while Popup#setDOMContent takes actual HTML nodes. i.e:
var h1 = document.createElement('h1');
h1.innerHTML="Hello, World";
popup.setDOMContent(h1);
both of those code snippets would result in identical Popup HTML contents. You wouldn't want to use both methods on a single popup because they are two different ways to do the same thing.
The problem in the code you shared is that you're trying to use the setDOMContent to add an event listener to your button, but you don't need to access the Popup object to add the event listener once the popup DOM content has been added to the map. Here is a working version of what I think you're trying to do: https://jsfiddle.net/h4j554sk/
I have a website manager that will return to me a different url for the server that my client should connect too.
So what I would like to do in my typescript function is resolve the first url, read the text, and then open that in a new window. Right now I can only open website manager window with the bellow code.
var aWindow = window.open("http://azureredirect.net/home/workspace/" + this.workspace.id, "Window", "");
if (aWindow) {
aWindow.focus();
}
What I really want is something like the following but the WebClient line does not work(this is the C# version of what I would do)
var url = WebClient.open("http://azurejupyterredirect.net/home/workspace/" + this.workspace.id").toString();
var aWindow = window.open(url, "JuPy", "");
if (aWindow) {
aWindow.focus();
}
here's an example of how you could do this:
$(document).ready(function() {
var workspaceId = '2';
$.ajax('http://azurejupyterredirect.net/home/workspace/' + workspaceId)
.then(
function(url) {
window.open(url);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
My current code pops up a warning box window telling the user that he or she is using IE. But is there a way to direct them to Firefox website?
public static boolean isIEBrowser()
{
return (Window.Navigator.getUserAgent().toUpperCase().indexOf("TRIDENT") != -1);
}
if (isIEBrowser())
{
SC.warn("It looks like you're using a version of Internet Explorer." +
" For the best GUI experience, please update your browser.");
}
Sure!
This might be more of what you're looking for.
String site = "http://www.mozilla.org/en-US/firefox/new/";
Window.Location.assign(site);
Window.Location.reload();
You can also add a simple timer that redirects them after a certain number of seconds or a button that takes them directly to the site.
edit:
Or... you can do this in pure javascript
JS:
function changeURL(site) {
window.location.href = site;
}
HTML:
<script>
changeURL('http://www.mozilla.org/en-US/firefox/new/');
</script>
This link (archived version) describes how to inject code from a script into an iframe:
function injectJS() {
var iFrameHead = window.frames["myiframe"].document.getElementsByTagName("head")[0];
var myscript = document.createElement('script');
myscript.type = 'text/javascript';
myscript.src = 'myscript.js'; // replace this with your SCRIPT
iFrameHead.appendChild(myscript);
}
That's ok, but what if I want to insert a function object into an iframe and get it executed in the iframe context? Let's say I have:
function foo () {
console.log ("Look at me, executed inside an iframe!", window);
}
and I want to insert foo's code inside an iframe? (function foo could be something loaded dynamically, I can't just wrap it in quotes)
I naively tried:
var scriptFooString = "<script>" + foo.toString() + "</script>"
to get the code inside function, but
I don't know how to insert it in the iframe HEAD (maybe with jquery?)
I don't know if it's the right way
I don't know what happens when if function is way more complex than that
I don't know what happens with double and single quotes in scriptFooString
Any hint?
First of all you can only accomplish this if your frame and the page displaying it is within the same domain (Due to cross-domain rules)
secondly you can manipulate dom and window objects of the frame directly through JS:
frames[0].window.foo = function(){
console.log ("Look at me, executed inside an iframe!", window);
}
to get your frame from a DOMElement object you can use:
var myFrame = document.getElementById('myFrame');
myFrame.contentWindow.foo = function(){
console.log ("Look at me, executed inside an iframe!");
}
Note that the scope in foo is NOT changed, so window is still the parent window etc. inside foo.
If you want to inject some code that needs to be run in the context of the other frame you could inject a script tag, or eval it:
frames[0].window.eval('function foo(){ console.log("Im in a frame",window); }');
Though the general consensus is to never use eval, I think its a better alternative than DOM injection if you REALLY need to accomplish this.
So in your specific case you could do something like:
frames[0].window.eval(foo.toString());
This code is the result of my research. The accepted answer also helped me a lot.
First of all, I create a simple iframe:
<iframe id="myiframe" width="200" height="200" srcdoc="<h1 id='title'>Hello from Iframe</h1><button type='button' id='fire'>Click Me!</button>
"></iframe>
For access to iframe's window and document I used this code.
const iframe = document.getElementById('myiframe');
const iframeWin = iframe.contentWindow || iframe;
const iframeDoc = iframe.contentDocument || iframeWin.document;
Finally I injected js codes into iframe:
var script = iframeDoc.createElement("script");
script.append(`
window.onload = function() {
document.getElementById("fire").addEventListener('click', function() {
const text = document.getElementById('title').innerText;
alert(text);
})
}
`);
iframeDoc.documentElement.appendChild(script);
Demo:
https://jsfiddle.net/aliam/1z8f7awk/2/
Here's my solution. I'm using jquery to insert the content, then using eval to execute the script tags in the context of that iframe:
var content = $($.parseHTML(source, document, true));
$("#content").contents().find("html").html(content);
var cw = document.getElementById("content").contentWindow;
[].forEach.call(cw.document.querySelectorAll("script"), function (el, idx) {
cw.eval(el.textContent);
});
Im trying to pass multiple things from a webpage inside a UIWebView back to my iPhone app via the shouldStartLoadWithRequest method of the UIWebView.
Basically my webpage calls window.location.href = "command://foo=bar" and i am able to intercept that in my app no problem. Now if i create a loop and do multiple window.location.href calls at once, then shouldStartLoadWithRequest only appears to get called on once and the call it gets is the very last firing of window.location.href at the end of the loop.
The same thing happens with the webview for Android, only the last window.location.href gets processed.
iFrame = document.createElement("IFRAME");
iFrame.setAttribute("src", "command://foo=bar");
document.body.appendChild(iFrame);
iFrame.parentNode.removeChild(iFrame);
iFrame = null;
So this creates an iframe, sets its source to a command im trying to pass to the app, then as soon as its appended to the body shouldStartLoadWithRequest gets called, then we remove the iframe from the body, and set it to null to free up the memory.
I also tested this on an Android webview using shouldOverrideUrlLoading and it also worked properly!
I struck this problem also and here is my solution that works for me.
All my JavaScript functions use this function __js2oc(msg) to pass data
and events to Objective-C via shouldStartLoadWithRequest:
P.S. replace "command:" with your "appname:" trigger you use.
/* iPhone JS2Objective-C bridge interface */
var __js2oc_wait = 300; // min delay between calls in milliseconds
var __prev_t = 0;
function __js2oc(m) {
// It's a VERY NARROW Bridge so traffic must be throttled
var __now = new Date();
var __curr_t = __now.getTime();
var __diff_t = __curr_t - __prev_t;
if (__diff_t > __js2oc_wait) {
__prev_t = __curr_t;
window.location.href = "command:" + m;
} else {
__prev_t = __curr_t + __js2oc_wait - __diff_t;
setTimeout( function() {
window.location.href = "command:" + m;
}, (__js2oc_wait - __diff_t));
}
}
No, iframe's url changing won't trigger shouldOverrideUrlLoading, at least no in Android 2.2.
