Suppose I have
def bar(request):
template = loader.get_template('activation/bar_chart.html')
context = RequestContext(request,{'name':'bar_chart'})
return HttpResponse(template.render(context))
I want to send a http get request via the javascript in the template
$.get('/bar/')
But it does not render the bar_chart.html, I still stay in the current html page.
If I use the load function in the jquery
$('body').load('/bar/')
then the content of bar_chart.html will replace the body of the current html page. But I want to go to a new page (that is, the url should be /bar)
How can I do that with django and jquery?
Thank you
If you want to go to the /bar/ page you just need to change the location property. JQuery is not needed here:
location.href = "/bar/";
I think i've run into this issue before as well.
If I remember correctly you can do the following
return HttpResponse(template.render(context), mimetype='application/json')

I am trying to create a function that change to another page depending certain value, I just can't find a way to do it.
Something like this
get the current page www.mypage.com
insert a new route
url = "/reports"
so when the funcion executes the page will redirect to www.mypage.com/reports or anything depending the url
$scope.searchPage = function (url) {
/// page = www.mypage.com + url
};
You can use $location(docs) to do this and your code will look like:
$location.path('/reports');
this will navigate to yourdomain.com/reports.
Another solution would be to use $window(docs) like:
$window.location.href = 'http://www.mypage.com/reports'
I personally use $location service to navigate inside the angularjs application and if you want to redirect to an external page in new tab via javascript you can do something like:
window.open('http://www.mypage.com/reports', '_blank');
To change the URL of a page with JavaScript, you just specify it on document.location.href:
document.location.href = 'http://example.com/new-page';
It is just a string, so you can build it however you want and pass it in.
For Angular, you can use the $window.location.href instead. Just be sure to inject the $window dependency:
$window.location.href = 'http://example.com/new-page';
Using the Angular way will allow a single-page-app to remain single page if it's within your site.
I am trying to transfer a variable from one page using this code:
Edit
to the page login.html, and insert the variable(asdf in this example) to a textbox in the new page.
I have tried this code:
function NameFunction(name) {
document.getElementById("username").value = name;
}
It is not working. I think it doesn't work because thats another page.
If you want to pass parameters to another page you can put them using query string:
Edit
To get parameter on the login.html page you can use jQuery as it described here: Get escaped URL parameter
you can try using localStorage.
In you're onClick method, save the data you want to store in localStorage
localStorage.setItem(key,value);
When the new page loads, in the onLoad (ready function if using jquery) method get the data from localStorage and set it in the textbox
you can find more about localStorage in the following links
Storing Objects in HTML5 localStorage
http://www.w3schools.com/html/html5_webstorage.asp
and many more are available online
How can I execute jQuery/JS code as soon as a jQuery/JS redirect like...
$(location).attr('href','/target_path');
...or...
window.location.href = "/target_path";
...has finished loading the new page?
Specifically, I need to pass an alert message and insert it into and display it (enclosed in some HTML) on the new page.
You can't. Once the redirect happens you are no longer on that page. You can't execute code on a page you are no longer on. If you want the next page to do something then you need to pass, either by cookie or URL parameter, a flag that instructs it to do so.
It is impossible to tell JavaScript to execute some code after a redirect.
However you have different options:
Pass a string in the redirect URL and then do something on "ready"
Store some information in a cookie and then do something on "ready"
Store some data using DOM storage (namely sessionStorage) if you don't mind the smaller browser support
You can't do that in the page that's redirecting. You can read the referrer in the landing page (document.referrer), and then decide whether to display an alert based on that, though.
var x = "It's some text";
var loc = '/target_path';
loc += '?message=' + encodeURI(x);
The JS file on the new page can then look at the query string to see if a message is there, and do the required action if it's detected.
You can use window.location.search on the new page to see what's there, although I'd recommend hunting for a deparam function in a library to turn the query string into a more usable object.
I am new to Dojo Framework.I created one button using dojo constructor and dojo.connect onclick event function i written url and load functions.This url navigating servlet and get the response back.
but i don't want response back i want to send request only.
how to do this..anyone help me.
thanks in advance.
are you looking to navigate to another page? if so, you can use window.location.href or other approaches to achieve that. See the foll url for other approaches:
JavaScript: Navigate to a new URL without replacing the current page in the history (not window.location)
if you do not want to navigate but just send some data to the server (and dont care about the response), you can just write an empty function for the callback
var deferred = dojo.xhrGet( {
url : "xxx",
load: function(data) {
//ignore
}
});
});
However, it is recommended to always check the response to ensure there were no errors on the server side.
You could also use dojo.xhrPost to submit your form
I want to get the title of a webpage without opening it, i.e. without using window.open().
I basically want to check whether the page i am providing the link for exists or an error is returned.
What I am trying is checking for similar links. Here is the code
(I want to know when to break out of this loop, i.e. at what point the link I am writing exists).
document.getElementById("TOI").innerHTML="<p>";
if (month<10) var m="0"+month;
else var m=month;
for(var i=1;;i++){
alert("ji");
var a="http://epaper.timesofindia.com/Repository/CAP/"+year+"/"+m+"/"+date+"/CAP_"+year+"_"+month+"_"+date+"_"+i+".pdf";
alert(a);
var link=window.open(a);
window.focus();
alert(link.location);
alert(link.document.title);
if(link.document.title!="The page cannot be found"){
link.close();
document.getElementById("TOI").innerHTML=document.getElementById("TOI").innerHTML+"<a href='http://epaper.timesofindia.com/Repository/CAP/"+year+"/"+m+"/"+date+"/CAP_"+year+"_"+month+"_"+date+"_"+i+".pdf' target=_blank>Page "+i+"</a> ";
}
else{link.close();break;}
}
document.getElementById("TOI").innerHTML=document.getElementById("TOI").innerHTML+"<\p>";
}
See to check if a url exists or not, you must use a server-side scripting language. Javascript is client-side and can't access server. So, first of all make a server side script (maybe php) that returns the status of url that you wanna check. Then from javascript side, use an ajax call to get the result of that script. That way you can check your url array, if all of them exists or not.
var attribute = element.getAttribute("title");

Just because a page has a title doesn't mean it exists.

Examine HTTP status codes rather than page titles:
