I have a html file with the following content:
<html>
<body>
<object data="https://upload.wikimedia.org/wikipedia/commons/0/09/America_Online_logo.svg" type="image/svg+xml"></object>
</body>
</html>
As you can check, you can open it with chrome and print it.
But if I use Chromium.Print method, it print empty pages.
Note that this is only a sample. All SVG images had the same problem.
I use Delphi 10.3.2 and CEF4Delphi.
Can any one guide me?
This is very likely caused by the CEF issue #3297 and the workaround described in that report works.
Add this code line before the GlobalCEFApp.StartMainProcess call :
GlobalCEFApp.DisableSiteIsolationTrials := True;
I tested this workaround with the latest CEF4Delphi version which uses CEF 100.0.14 and the MiniBrowser demo. Your sample HTML is printed correctly with TChromiumCore.Print and TChromiumCore.PrintToPdf.
I am trying to add a yes/no message box to a google sheet that will display on an iPad. I have tried all the things below but none of them display the message. My goal is if the user changes a field the macro will change other fields if the user says it is ok. I can get this to work on a windows machine with no issues but when I try it on an ipad the message never appears. At this point I am just trying to get a message box to appear. This is what I have tried
1.
function onEdit(e) {
Browser.msgBox("test");
}
Result: The macros times out
2.
function onEdit(e) {
var html = HtmlService.createHtmlOutputFromFile('Page')
.setWidth(400)
.setHeight(300);
SpreadsheetApp.getUi() // Or DocumentApp or SlidesApp or FormApp.
.showModalDialog(html, 'My custom dialog');
}
Page.html:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
Hello, world! <input type="button" value="Close" onclick="google.script.host.close()" />
</body>
</html>
I enabled the trigger for onEdit to get it to work and it works on the windows machine without issues but when run on the iPad I get:
Exception: You do not have permission to call Ui.showModalDialog. Required permissions: https://www.googleapis.com/auth/script.container.ui
So next I tried:
3.
function myFunction(){
Logger.log("myFun")
var html = HtmlService.createTemplateFromFile( 'Page' )
.evaluate()
.setWidth( 800 )
.setHeight( 400 );
SpreadsheetApp.getUi() // Or DocumentApp or FormApp.
.showModalDialog( html, 'My page title' );
}
function onEdit(){
ScriptApp.newTrigger('myFunction')
.forSpreadsheet(SpreadsheetApp.getActive())
.onEdit()
.create();
}
Using the same page.html, this time in executions it looks like it runs but no box appears on the ipad(it does work on windows). I also tried spreadsheetApp.getUi().alert and prompt, these had the same results.
And Yes I have to use the iPad, I can not use another type of tablet.
Issue:
"Exception: You do not have permission to call Ui.showModalDialog. Required permissions: googleapis.com/auth/script.container.ui"
Fix:
What you can do is installing the trigger instead of using a simple trigger. The image below shows the difference between an installed (above) and a simple (below) trigger using the same code.
Output:
Note:
Don't use reserved function names on installed triggers to avoid it being executed twice like what's shown above. Change onEdit to something like promptUI or something else.
If the above fix isn't enough to show the dialog box, then we need to confirm if the issue might just be on the safari browser (if you are using one) since it worked on your other devices which I assumed are not using safari. You can try using an alternative browser in your device such as Google Chrome and see if the same issue persists. I recommended doing this since i'm seeing a number of issues between showModalDialog and safari
EDIT:
I have seen these related posts pointing out that there are some limitations on mobile apps. See the references below.
Also, some answers suggests that you need to access the spreadsheet via browser (google chrome desktop mode) and then trigger the script there.

How to get scripts to work with phones and tablets
I'm still trying to make the invokescriptasync work. I'm trying the following test on facebook.com and it fails with a HRESULT: 0x80020101' which normally means the script has an error in it, but I tried running the simple javascript in Chrome and IE without any problem.
private async void WebView_OnNavigationCompleted(WebView sender, WebViewNavigationCompletedEventArgs args)
{
await _webView.InvokeScriptAsync("eval", new[]
{
"document.getElementById('blueBarDOMInspector').innerHTML = '';"
});
}
Thanks
I have tested your code and the error is thrown only in case the blueBarDOMInspector is not found. I used the following simple HTML:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body>
<p id="blueBarDOMInspector"></p>
</body>
</html>
You can confirm that the script works as expected with this HTML. So I suspect the problem is rather on HTML side than on side of UWP.
As for ScriptNotify not working - the website must be HTTPS and be added as trusted to appxmanifest. Better solution is web allowed object. A great example was posted in a question yesterday on SO or here as a sample project. Basically you have to create a Windows Runtime Component with a class marked as [WebAllowed] and then inject it in the WebView using AddWebAllowedObject method.
For your invoking JavaScript code issue,I've checked your code, it's simple, the possible issue might be the 'blueBarDOMInspector' object, please make sure that you could get the 'blueBarDOMInspector' object successfully when the OnNavigationCompleted is fired.
For your second question:
I can invoke the script : "window.external.notify('something');" but it doesn't raise the event ScriptNotify which is another problem :-(
Please check the document:
To enable an external web page to fire the ScriptNotify event when calling window.external.notify, you must include the page's Uniform Resource Identifier (URI) in the ApplicationContentUriRules section of the app manifest.
I'm currently having an issue with the WebView control used in a Universal WinRT app (Windows 8.1/Windows Phone 8.1).
I currently load the following piece of JavaScript into the WebView using the NatigateToString method:
<html>
<head>
<base href='MY_BASE_URL'>
</head>
<body>
<script>
var idcomments_acct = 'MY_ACC_ID';
var idcomments_post_id='POST_ID';
var idcomments_post_url='POST_URL';
</script>
<span id='IDCommentsPostTitle' style='display:none'></span>
<script type='text/javascript' src='http://www.intensedebate.com/js/genericCommentWrapperV2.js'></script>
</body>
</html>
This is the piece of code for the IntenseDebate generic install that can be found here.
The issue is with this line of code in the referenced IntenseDebate code:
load_js(document.location.protocol+"//connect.facebook.net/en_US/all.js")
This piece of code fails because document.location.protocol is set to about: in the WebView, leading to a 404 error on this call.
On the Android/iOS webviews simply setting the base URI to a http: or https: based address using their loadDataWithBaseUrl methods worked fine, but the WinRT WebView is missing a similar method. And setting the Base url in the HTML itself (like shown in the piece of code above) does work for resolving image url's and sortlike, but this method doens't change the document.location values.
Since I can't modify the referenced JS file and putting the above piece of HTML on a server isn't an option in this apps usecase, is there any way you can force the document.location.protocol to be a certain value in the WinRT webview? Or is there any other way to get this bit of HTML to work in a webview?
There isn't a direct way to do this. WebView doesn't provide any interface to override the document.location . If branching off of the protocol is a common pattern then this may be a good feature to request on http://wpdev.uservoice.com .
I'm not familiar enough with HTML/JavaScript best practices to say for sure, but most of the references I find searching for document.location.protocol warn against assuming that the protocol will always be http: or https. This may be something that IntenseDebate should fix.
That said, you may be able to get past this by injecting code into your page which finds the problem location in the DOM and changing it live. You can't change just the protocol, but you may be able to find where it is referenced and change that there. I assume it gets loaded into the commentScript.src from genericCommentWrapper2.php referenced in genericCommentWrapper2.cs and then added to the document's head.
I'm using "Jquery UI 1./Dan Wellman/Packt Publishing" to learn JQuery UI. I'm working on the 'Dialog widget' chapiter.
After I've completed a series of exercises in order to build a Dialog widget (using Google Chrome), I then tried my work with Internet Explorer and Firefox.
The result has been disappointing.
Chrome was perfet
With Internet Explorer, (1) the title of the Dialog widget did not appear, (2) The location of the dialog widget was not correct (given the position: ["center", "center"]). It was rather offset toward left.
With Firefox, the location was respected. However, only the outer container was visible. the content was missing, just a blank container.
Also using Option Show:true and Hide:true did only work with Chrome.
I wonder now if JQuery UI was meant to be used only with Google Chrome. I just think that I might be missing some directives to make it work with major browsers (as the author claimed in his book).
Here's the code. Since, I'm using ASP.NET MVC, certain codes, such as the element to the css, do not appear. But, for the rest, all the functioning code is bellow.
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<p>
The goal of this tutorial is to explain one method of creating
model classes for an ASP.NET MVC application. In this tutorial,
you learn how to build model classes and perform database access
by taking advantage of Microsoft LINQ to SQL. In this tutorial,
we build a basic Movie database application. We start by creating
the Movie database application in the fastest and easiest way possible.
We perform all of our data access directly from our controller actions.
</p>
<div style = "font-size:.7em" id = "myDialog" title = "This is the title">
In this tutorial -- in order to illustrate how you can build model classes
-- we build a simple Movie database application.
The first step is to create a new database. Right-click the
App_Data folder in the Solution Explorer window and select the menu option
Add, New Item. Select the SQL Server Database template, give it the name
MoviesDB.mdf, and click the Add button (see Figure 1).
</div>

minWidth: 500,
minHeight: 500,
buttons: {
"OK": execute,
"Cancel": cancel
},
show:true,
hide: true,
bgiframe:true
};
$("#myDialog").dialog(dialogOpts);
});
</script>
Thank for helping.
EDIT
I've re-done the same exercise yesterday. From the beginning to the end, each time I've introduced a behavior, I've tested my work in all 3 browsers (IE, Firefox, Chrome).
Everything works until I add option Show and Hide. Then only Chrome works.
If I remove Show and Hide, everything works again.
If I keep only Show and Hide, everything works perfectly
Maybe Show and Hide options for dialog widget do not mix up well with other options.
Thanks for helping.
No, jQuery UI works in any of those browsers. It's probably either the steps you're following don't work so well with the version you're using or the version you're using is old. I've used jQuery UI without issue on both browsers. If you don't believe me, then open this URL in your browser:
http://jqueryui.com/demos/dialog/
In Firefox 3.6, it loads just fine for me.
I'm not an expert on jQuery UI, but providing the code here might help.
jQuery supports all the major browsers however there are know issues with;
Firefox 1.0.x
Internet Explorer 1.0-5.x
Safari 1.0-2.0.1
Opera 1.0-8.x

We have successfully implemented a Dialog widget without major issues. We did have some problems making sure the correct versions of the libraries were created. I would suggest you build a custom file using the jQuery UI download tool. This will put all the necessary files in a single minified file.
If the Dialog examples don't help then posting code will be necessary to obtain further help.
EDIT:
I have anchors created with the classes dialogOpen and dialogClose and use the following code to utilise the created UI Dialog;
$(document).ready(function(){
var dialogOpts = {
autoOpen: false,
modal: true,
width: 840,
height: 560
};
$(".dialogOpen").click(function(){
$("#myDialog").dialog("open");
return false;
});
$(".dialogClose").click(function(){
$("#myDialog").dialog("close");
return false;
});
$("#myDialog").css('display','block').dialog(dialogOpts);
$(".ui-dialog-titlebar").hide();
});
NB: The use of the css function when creating the dialog stops the content appearing on the page before the Dialog is created. We needed this because our dialog has flash.
You may be missing something. It surely works in all major browsers.
jQuery is ment to be cross browser. Any errors with this can have to reasons
- Programmer's error
- Explicit incompatibilty
There are some explicit incompatibility's with IE5.5 and IE6 in jQuery. They are in the comments of jQuery and a good js compatible IDE like netbeans will allow targeting and warn you about it.
I never had any problems with the dialog widget positioning or contents.
jQuery UI is most definitly not designed to work with Google Chrome only.
I've successfully created applications using jQuery UI working on all major browser platforms.
jQuery UI (and jQuery) contain code to work around certain browser issues.
Of course there can be issues in jQuery UI which show on IE, like this one, but those are certainly not by design.
