I'm trying to back end this and maybe get lucky modifying the url, what happens is there is javascript code that loads specific data and I want to be able to pass in the script via the URL. Is this possible and how would i do it?
For example here is the javascript: javascript:ChangeEvsVol('1035','3')
here is the urL:https:///app/template/simple%2CDownloadQuotasScreen.vm
Is there a way to manipulate the URL to use that param? I throw in into Firebug command console and it grabs exactly what I need.
document.location ="mysite.php?var1=" + JSvar1 +"&var2=" + JSvar2

I am facing issue in angular js, right now we have two urls in our application,
http://localhost/xyz?page=documents&view=grid&sortorder=desc&sortby=updatedate&limit=35&offset=0
and then we another url
http://localhost/abc
When i move from the first url to the second url it carries the query params from the first url, this is how the second url looks like
http://localhost/abc?page=documents&view=grid&sortorder=desc&sortby=updatedate&limit=35&offset=35
We don't the fetch url carrying the query params from the first page. I am new to angular js, I have came across few options like
$location.search({});
$location.url($location.path())
But those didn't work at all.
I think i know what you mean, to remove parameters use
$location.url($location.path());
Hope it helps
Check this documentation for the location with angular
1.Save the query object $location.search()in some place (local storage or cookies), then in the target controller $.map(query,funcion(k,v){ $location.search(k,v});
2.Dynamically append to the end url2 + $location.path() in href attribute
$location.url changes path, search and hash.
So, $location.url('new_path') should work!
I'm quite new to JavaScript and Node JS and I have a such a situation. When I try to call get of express.js with a single parameter everything works fine, but when I try to call get with more than one parameter, it trims the query.
For example I have such call and function
app.get('path/data', myFunc);
// in another file
function myFunc(req, res) {
// do some stuff
}
When the url is path/data?id=5 or path/data?name=foo everything is fine. But when I use for example url like path/data?id=5&name=foo in myFunc I get url as path/data?id=5. So I get url's first part - what is before & sign.
Now what am I doing wrong? Is there something that I'm missing? How can I get whole url in myFunc without being trimmed?
Use
app.get('path/data?:id?:name')
And for retrieving the values, use req.query.id and req.query.name.
For accessing the REST api, you need to hit:
http://localhost:8080/demo?id=3&name=stack
So, by this you can add multiple parameters in your api.
Hope this helps.
I found the problem. I was requesting via curl and it turns out that shell command trims in case of there is an & in the url. So there is a need no add quotes like this
curl "path/data?id=5&name=foo"
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 calling another application context from window.showModalDialog but confused with following work. Same code to pass parameter within showModalDialg.
var myArguments = new Object();
myArguments.param1 = "Hello World :)";
window.showModalDialog("java2sTarget.html", myArguments, '');
and i can read these myArguments(parameters) in generated HTML using following code:
<script>
document.write(window.dialogArguments.param1);//Hello World :)
</script>
I can't use query string & i am sending myArguments(parameter) because i want to hide parameter from Application user.
Now i am calling servlet from showModalDialog(..)
onclick="window.showModelDialog('http://localhost:7778/app/servlet/test',myArguments,'');"
onclick="window.showModelDialog('http://localhost:7778/app/servlet/test',myArguments,'');"
But as per my knowledge
Servlet --> Servlet container --> HTML+JS+CSS
so JS will be available at last phase, but i want to use in first phase(Servlet).
Now, i need to make some Decision in servelt code based on myArguments(parameter).
is there any way to read these myArguments(parameters) in servlet code?
Pass it as a request parameter in the query string.
var queryString = "param1=" + encodeURIComponent("Hello World :)");
onclick="window.showModelDialog('http://localhost:7778/app/servlet/test?' + queryString, myArguments, '');"
No, there's no other alternative. The request URL is not visible in the modal dialog anyway.
As main objective is to hide query string from User to avoid misuse of those parameters.
I tried following work around.
Developers send hidden parameters to get relative information form source(e.g.:DataBase). And we also know that we can send hidden information in Window.showModalDialog using dialogArguments
Work Around:
(i) I got relative information from server one-step before calling Window.showModalDialog using jQuery.getJSON()
(ii) i used google-gson API at servlet side to convert JavaBeans into Json strings.Solution 1 Solution 2
(iii) Convert JSON into javascript object using jQuery.parseJSON
var args = jQuery.parseJSON(json);
window.showModalDialog("pages/"+args.pageName, args, '');
i used args.pageName to make things dynamic
Please suggest improvements in this work-around. Thanks
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:
Can Prototype or JQuery return an HTTP status code on an AJAX request
