I am using angular-translate and its extension angular-translate-loader-static-files to i18 my angular app. Both the required JS files are included in the index.html.
Everything works as expected except that the screen shows the raw message code for a second before we can see the translated messages. I think that happens because the enUS.json (the message translation json) is fetched using an ajax call and until its completed, raw message codes get displayed.
Is there any way of fixing this?
Your issue is not specific to angular-translate.
Either use
https://docs.angularjs.org/api/ng/directive/ngCloak
or

Is is it possible to return JSON (www.myapp.com/json) without any Angular additions on Angular page, like backend endpoint would return?
E.g this <pre>{{jsonToDisplay | json}}</pre> doesn't work, because when you look browser source you can see also Angular generated code.
You can add a json pipeline to transform data directly in the html as yo are doing, rememeber to import CommonModule 1.
If it does't work, you could implement a custom pipeline.

What I am going to try is to get the HTML of a page and reproduce it into an iFrame (it is an exercise).
I am using the following piece of code:
var prova = this._http.get(myUrl, {responseType: "text"}).subscribe((x) =>{
console.log(x);
});
I did it on a website (if is needed I can also insert the name of the pages) and it returns the html only of some pages.
In the other case the string x is empty.
Could it depend on connection?
Or there is some way to wait the end of the get request?
Or simply is wrong my approach and I should make a different type of request?
Your most likely going to need to use a library like puppeteer if you want to render a page properly. Puppeteer is a node library and useless headless chrome so I am not sure how well you could really integrate with Angular.

I'm writing an app in Swift 3.0 and I'm trying to scrape data from the search results of a webpage. I perform the search by including the search query as a parameter in the url, but the html that's getting returned to me has no results. I believe this is because the ajax on the webpage has not finished and populated the html with the search results by the time the html is returned to my app.
Question
How do I wait for the search results to load before getting the html?
EDIT:
URL: https://uscdirectory.usc.edu/web/directory/faculty-staff/#basic=a
This url performs a search on the USC directory for the character 'a'. The html in my browser on my MacBook includes these tags:
<tbody>(Search results are here)</tbody>
but in my app the html that is returned to me has nothing:
<tbody></tbody>
This is because the webpage initially has no search results, and then some time later the ajax finishes and the table body is populated. How do I use a URLSessionDataTask object in Swift to wait until the ajax finishes and ONLY THEN give me the html, such that I actually get the search results?
The workaround solution that I devised is unpleasant but functional. I created a WKWebView off screen and loaded the webpage I was interested in. I used a Timer to wait some arbitrary number of seconds for the javascript on the page to finish and then I retrieved the html from the webview
You can use property ajaxComplete() to fix this.
Ex:
$(document).ajaxComplete(function(){
//your code to render HTML
});
It will render your HTML only when ajax request is complete.
I am trying to open HTML file from the local URI which I use as XML Editor, to edit xml data that come from Silverlight application, then close browser window and return back edited xml data to the Silverlight application.
I tried to use HtmlPage.Window.Navigate but I don't quit like it.
I have tried using a method from: http://weblogs.asp.net/dwahlin/archive/2010/05/10/integrating-html-into-silverlight-applications.aspx
but instanly got an exception "failed to invoke ShowJobPlanIFrame"
Is there any way to handle this task?
"Out of browser" mode doesn't fit.
Thanks.
===========================================================================
Update:
It worked out using IFrame overlay.
Button click invokes the following code in C#:
var scriptObject = (ScriptObject)HtmlPage.Window.GetProperty("ShowJobPlanIFrame");
scriptObject.InvokeSelf(url);
Where "ShowJobPlanIFrame" is as defined at:
http://weblogs.asp.net/dwahlin/archive/2010/05/10/integrating-html-into-silverlight-applications.aspx
This allowed me to pass data into XML editor and then get it back.
An error with JavaScript function invocation I told above, was my fault in JavaScript code itself.
A very similar scenario: https://stackoverflow.com/a/7919065/384316
Try using an iframe overlay, then you can load any HTML-like content.
There is an excellent explanation of how to do this here:

Did you try NavigationFramework of Silverlight? It's capability may support your needs in a more simple way than using multiple browser pages.
I have a problem receiving and opening a picture via AJAX.
If I call the following page:
http://127.0.0.1:8889/ex?sql=SELECT+Image+FROM+Persons+WHERE+Number+Like+%27%2501%27
a picture is displayed from a blob field in IE8.
Now I would like to open this into a div after someone pressed a key (using AJAX)?
Trying to use xhr.responseText does not work (I get an error. Using it on a text response works). So it seems that my problem is to grab the result from the ajax request.
How can I do this?
Some code and the error message:
var picReturn = xhr.responseText;
=> Could not continue due to the following error: c00ce514
You have three options:
Place the resultant data in an iframe. Not very practical.
Take the result and place it in am image source as a data:uri. Not supported in older browsers and limited to 32/64Kb depending on the browser.
Skip the AJAX and write a web service and use that as your url. This is the best option.
You don't say what language you're using server-side but you essentially want to open a web response, set the header to "image/jpeg" and return your stream.
