I've got GWT module where I do some stuff and I have search results - doesn't matter in which form. Now after searching, and clicking on for example "Export to HTML" button,I would like to create new html page (for example from client side code by creating simple string which contains only listed results of searching list of results ) and open it in new browser window. I know that there is Window.open(...) method, but there I must specify url which i don't have. I want to create this new html page by client side - without server inference (I don't want to create some resource on server side and then paste url to this resource to client side). Is there any possibility to achieve this? If there is no option, other method which would satisfy me, is to open standard dialog box for saving, which will allow to save results in a html file.
Thanks for helps.
Kind regards.
Here's the code I use to print:
native void openPrintWindow(String contents) /*-{
var printWindow = window.open("", "PrintWin");
if (printWindow && printWindow.top) {
printWindow.document.write(contents);
printWindow.print();
printWindow.close();
} else {
alert("The print feature works by opening a popup window, but our popup window was blocked by your browser. If you can disable the blocker temporarily, you'll be able to print here. Sorry!");
}
}-*/;
Seems like you could adapt it for your purposes with some simple rewording and by removing the call to print()! The contents variable just holds flat HTML. There are no trips to the server.
openPrintWindow("<h1>Search Results</h1><ol><li>etc...");
The method of opening new window from client js which allows user to save that generated content from browser's save as menu is data:url scheme, content written to opened page via println usualy not saved. But data:url works only in morden browsers. And the content written should be quite small to fit browser's url length resteiction.
See example from this article http://en.wikipedia.org/wiki/Data_URI_scheme#JavaScript

I am trying to open a new window with the below code. It opens a new window but it has the url as "about:blank". How to change the this url and give a custom url.
private native void openPrintWindow(String contents) /*-{
var printWindow = window.open("", "PrintWin", false);
printWindow.document.open("text/html","replace");
if (printWindow && printWindow.top) {
printWindow.document.write(contents);
} else {
alert("The print feature works by opening a popup window, but our popup window was blocked by your browser. If you can disable the blocker temporarily, you'll be able to print here. Sorry!");
}
}-*/;
It is empty, because first parameter of window.open method is an empty string. Check some examples here. So it should be something like this:
window.open("https://stackoverflow.com", "PrintWin", false);
From Your code I see You want to open a new window by custom URL with some HTML content inside. You cannot do it this way. If You put some URL, the browser will try to open this URL by making a GET request.
Solution to what You want to achieve is to do it more-or-less the MVC way (please note it is NOT a fully correct MVC solution, just a guidance):
Before You open the window, You need to store a content somewhere (best option is on a server side, but there is also a way to store it on a client side)
Create a new page, accessible via Your custom URL (either a simple HTML or a service, up to Your needs).
You need to write some code in this new page which will retrieve Your content (stored previously somewhere) and present it in this newly opened window.
i am using GWT app engine to deploy my application in local host.
i want to redirect to second page when user completed his registration & clicked "submit" button, the browser has to redirect to automatically to his Profile page with his registration details.
i used fallowing code to redirect to second page from first page;
String url = GWT.getHostPageBaseURL()+"/UserViewProfile.html";
Window.Location.replace(url);
in my case the first page is URL is like:
http://127.0.0.1:8888/UserRegistration.html?gwt.codesvr=127.0.0.1:9997
when i submitted on "Submit" button it is edirecting to URL like:
http://127.0.0.1:8888/UserViewProfile.html
In second page(UserViewProfile.html) i developed simple HTML content & simple Textbox widget to check it's functionality. But i am seeing HTML content only but not "Textbox".
To see text box i has to type URL like:
http://127.0.0.1:8888/UserViewProfile.html?gwt.codesvr=127.0.0.1:9997
how i can access last part "?gwt.codesvr=127.0.0.1:9997" at end of my URL pattern automatically? if i add it manually, at the time of hosting it may leads to problem. please if any body give solution, that would be great.
I do not understand the use case. Anyway I guess you need to conditionally check if you are in DevMode or ProdMode, and add the gwt.codesvr=127.0.0.1:9997 query string accordingly. Something like:
String url = GWT.getHostPageBaseURL()+ "/UserViewProfile.html";
if (GWT.isProdMode()) {
Window.Location.replace(url);
} else {
Window.Location.replace(url + "?gwt.codesvr=127.0.0.1:9997");
}
The gwt.codesvr=127.0.0.1:9997 query string parameter is used by GWT to (simplifying) bootstrap your app in the so called Development Mode, instead of the Production Mode (the actual compiled version of your application). Without this check, if you are in DevMode, you end up requesting the UserViewProfile.html that looks for the compiled version of your app (that does not show anything, if you've never compiled it, or if you have simply recently clean the project).
Do also note that URL rewriting (by not simply changing the # fragment identifier), means application reloading.
I am using GWT2.4 version in my application.In this I application I have created Form using GWT control (like textbox,textaera).
I have also created preview of form.In that preview I have button of pdf generation.
Now I want to create behavior to deal with pdf link same as browsers(Mozilla/chrome).
For example in Mozilla on click of pdf link it asks for either save or open in a pop up window.
While debugging I found a jar name iText which can be used to create pdf, I want to implement browsers behavior in this also.
Please help me out.
Thanks in advance.
Read file contents into byte array.
Then do request for servlet or service, for eg. this way:
Window.Location.replace("rest/downloadPdf");
That Service should return Response with the right content type:
#Path("downloadPdf")
#GET
#Produces({"application/pdf"})
#Consumes(MediaType.TEXT_PLAIN)
public Response downloadPdf() throws Exception {
byte[] bytes = getYourPDFContents();
return Response
.ok(bytes, MediaType.APPLICATION_OCTET_STREAM)
.header("Content-Disposition", "attachment; filename=\"yourFile.pdf\"")
.build();
}
Browser will then show save as dialog.
That's example of Service, you must include Jersey library into your project to be able to use method like I've wrote above .
Does Google provide API access to autocomplete for search like on the actual site? I have not been able to find anything.
I would like to use Google's autocomplete logic for web search on my own site which relies on Google's search API.
The new url is:
http://suggestqueries.google.com/complete/search?client=firefox&q=YOURQUERY
the client part is required; I did't test other clients.
[EDIT]
If you want the callback use this:
http://suggestqueries.google.com/complete/search?client=chrome&q=YOURQUERY&callback=callback
As #Quandary found out; the callback does not work with client "firefox".
[EDIT2]
As indicated by # user2067021 this api will stop working as of 10-08-2015: Update on the Autocomplete API
First, go to google, click Settings (bottom right corner), change Search Settings to "never show instant results. That way, you'll get regular autocomplete instead of a full page of instant results.
After your settings are saved, go back to the Google main home page. Open your browser's developer tools and go to the Network tab. If you're in Firefox, you might have to reload the page.
Type a letter in the search box. A new line should appear in the Network window you just opened. That line is showing where the autocomplete data came from. Copy that url. It should look something like this:
https://www.google.com/complete/search?client=hp&hl=en&sugexp=msedr&gs_rn=62&gs_ri=hp&cp=1&gs_id=9c&q=a&xhr=t&callback=hello
You'll notice your search term right after the part that says q=.
Add &callback=myAmazingFunction to the end of the url. You may replace myAmazingFunction with whatever you want to name your function that will handle the data.
Here's an example of the code required to show the autocomplete data for the search term "a".
<div id="output"></div>
<script>
/* this function shows the raw data */
function myAmazingFunction(data){
document.getElementById('output').innerHTML = data;
}
</script>
<script src="https://www.google.com/complete/search?client=hp&hl=en&sugexp=msedr&gs_rn=62&gs_ri=hp&cp=1&gs_id=9c&q=a&xhr=t&callback=hello&callback=myAmazingFunction"></script>
Now that you know how to get the data, the next step is to automatically change that last script (the one with the autocomplete url). The basic procedure is: each time the user types something in the search box (onkeyup) replace the search term (q=whatever) in the url, and then append to the body a script with that url. Remove the previous script so that the body doesn't get cluttered.
For more info, see http://simplestepscode.com/autocomplete-data-tutorial/
Most of the above mentioned methods works for me, specifically the following serves my purpose.
http://suggestqueries.google.com/complete/search?client=firefox&q=YOURQUERY
Being a newbie in web programming, I'm not much aware of the "Callback" functionality and the format of the file returned by query. I'm little aware of AJAX and JSON.
Could someone provide more details about the format of file returned by the query.
Thanks.
Hi I don't know if this answer is relevant for you anymore or not but google returns JSON data through following get request (although this isn't an official API but many toolbars are using this API so there's no reason why google might discontinue it):
http://google.com/complete/search?q=<Your keywords here>&hl=en
You should use AutocompleteService and pass that text box value into the service.getPlacePredictions function. It send the data in callback function.
let service = new google.maps.places.AutocompleteService();
let displaySuggestions = function(predictions, status) {
}
service.getPlacePredictions({
input: value
}, displaySuggestions);
Base: https://developers.google.com/maps/documentation/javascript/reference/places-autocomplete-service#AutocompleteService.getPlacePredictions
example: https://dzone.com/articles/implement-and-optimize-autocomplete-with-google-pl
I'm using (( Edrra.com )) API that have google search and suggestions that works with both GET & POST:
Google suggestions:
https://edrra.com/v1/api.php?c=google&f=suggest&k=YOUR_API_KEY&v=YOUR_SEARCH
Google search:
https://edrra.com/v1/api.php?c=google&f=search&k=YOUR_API_KEY&v=YOUR_SEARCH
and more...
What are you trying to use an auto-complete for? More information would help narrow it down.
As far as I know, google does not provide one, but they do exist like jQuery UI's auto-complete.
EDIT:
If you are using their custom search API view here for autocomplete.
I'm trying to write a Greasemonkey script for Facebook and having some trouble with the funky page/content loading that they do (I don't quite understand this - a lot of the links are actually just changing the GET, but I think they do some kind of server redirect to make the URL look the same to the browser too?). Essentially the only test required is putting a GM_log() on its own in the script. If you click around Facebook, even with facebook.com/* as the pattern, it is often not executed. Is there anything I can do, or is the idea of a "page load" fixed in Greasemonkey, and FB is "tricking" it into not running by using a single URL?
If I try to do some basic content manipulation like this:
GM.log("starting");
var GM_FB=new Object;
GM_FB.birthdays = document.evaluate("//div[#class='UIUpcoming_Item']", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
for (i = GM_FB.birthdays.snapshotLength - 1; i >= 0; i--) {
if (GM_FB.birthdayRegex.test(GM_FB.birthdays.snapshotItem(i).innerHTML)) {
GM_FB.birthdays.snapshotItem(i).setAttribute('style','font-weight: bold; background: #fffe88');
}
}
The result is that sometimes only a manual page refresh will make it work. Pulling up the Firebug console and forcing the code to run works fine. Note that this isn't due to late loading of certain parts of the DOM: I have adding some code later to wait for the relevant elements and, crucially, the message never gets logged for certain transitions. For example, when I switch from Messages to News Feed and back.
Aren't they using ajax to load content in a div? You can find the element which is being updated by using Firebug for example.
When you click something and the URL changes, but with a # on the URL and after this some text, it means the text is not a path, it's a parameter, the browser won't change the page you are, so since GreaseMonkey inject the script on the page loads it won't inject again, because the page is not reloading.
As in your example the URL facebook.com/#!/sk=messages is not navigating away from facebook.com/ it will not fire window.load event.
So you need to find which element is being changed and add an event listener to that element, you can do is using Firebug as I mentioned before.
After you find out what element is getting the content, you have to add an event listener to that element and not the page (GreaseMonkey adds only on the window load event).
So in you GM script you would have ("air code")
document.getElement('dynamic_div').addEvent('load', /*your script*/);
