I have a page that contains a login form. I am calling a separate function (which resides in a separate .js file) on the onsubmit event of the form. Below is the function
var LoginClick = function() {
// Omniture Code
s.linkTrackVars="events, eVar1";
s.linkTrackEvents="event1";
s.events="event1";
s.eVar1="Login";
s.tl(true, "o", "Login Clicks");
};
while the events data is getting passed on the s.tl call, the evar1 value turns up as "none" in the conversion report. I used a packet sniffer (omnibug) to check the values being passed. Even though s.eVar1 is assigned the value "Login" it does not pass that value.
Ofcourse, s.t() works well (evar value gets passed) but I dont want to do that.
I have tried s.tl(this, "o"...) which doesnt work either.
What am I doing wrong here?
Appreciate your time and help.
remove the space between the comma and eVar1
s.linkTrackVars="events, eVar1"
should be
s.linkTrackVars="events,eVar1"

I had this app that fetches some data from a remote API. So the data that I am going to receive and display in a JSON Future:
{"status":200,"out":{"summary":[{"bc":"1876","wc":"488679","pc":"731904"}],"last":[{"id":"1877","place":"7","publisher":"-1","bookid":"01877","title":"Neither Civil Nor Servant","author":"Peh","region":"\u65b0\u52a0\u5761","copyrighter":"","translated":"0","purchdate":"2017-04-18","price":"200.00","pubdate":"2016-01-01","printdate":"2016-01-01","ver":"1.1","deco":"\u666e\u901a","kword":"0","page":"220","isbn":"978-981-4642-63-7","category":"","location":"","intro":"TT\u8d60\u4e66\u3002","instock":"1","p_name":"\uff08\u672a\u6307\u5b9a\uff09"}]}}
I will extract the out field from this JSON and assing summary and last to two variables:
initState() async {
var getter = createHttpClient();
String uri='http://api.rsywx.com/book/summary';
var res=await getter.get(uri);
Map data=JSON.decode(res.body);
var out=data['out'];
setState(() {
_today=formatDate(new DateTime.now());
_lb=out['last'][0];
_bs=out['summary'][0];
_lb['purchdate']=formatDate(DateTime.parse(_lb['purchdate']));
});
}
So _bs and _lb are all compound objects.
In my widget build function, I will display the contents of these two objects:
new TextSpan(
text: numFormatter.format(int.parse(_bs['bc'])),
style: aboutTextStyle,
),
The program compiles OK but when launched, a quick splash RED screen will appear:
And soon enough, the correct screen will appear:
I know that during the initial build, the object _bs, _lb is not there yet and the async call to a remote API is still trying to populate the returned response, so in this case, _bs['bc'] will definitely be not callable. Thus the non-blocking error pops out.
Workaround
I can eliminate this error by declaring a bunch of variables and assign them in the initState function; instead of rendering _bs['bc'], I will render a new variable _bookCoount. This way, the rendering will be done without this RED screen and the value of that variable will initially be null and soon be the correct value fetched from remote API.
But this is too cumbersome, if you get what I mean: A lot of used-only-once variables.
Or, shall I make the data fetched on the parent level, so that it will be passed to this widget as props? Not tried yet.
Would appreciate your best practice input.
Update
The issue really comes from int.parse. If I took out that call, the program runs peacefully.
So the question now becomes
I would suppress int.parse prompting an error before the value it is going to parse becomes valid.
Not sure what you mean with your workaround. In your example setState() won't be called before await getter.get(uri); returns a value.
I guess this should do
new TextSpan(
text: _bs != null && _bs['bc'] != null ? [numFormatter.format(int.parse(_bs['bc'])) : 0,
style: aboutTextStyle,
),
I want to examine http requests in an extension for firefox. To begin figuring out how to do what I want to do I figured I'd just log everything and see what comes up:
webRequest.onResponseStarted.addListener(
(stuff) => {console.log(stuff);},
{urls: [/^.*$/]}
);
The domain is insignificant, and I know the regex works, verified in the console. When running this code I get no logging. When I take out the filter parameter I get every request:
webRequest.onResponseStarted.addListener(
(stuff) => {console.log(stuff);}
);
Cool, I'm probably doing something wrong, but I can't see what.
Another approach is to manually filter on my own:
var webRequest = Components.utils.import("resource://gre/modules/WebRequest.jsm", {});
var makeRequest = function(type) {
webRequest[type].addListener(
(stuff) => {
console.log(!stuff.url.match(/google.com.*/));
if(!stuff.url.match(/google.com.*/))
return;
console.log(type);
console.log(stuff);
}
);
}
makeRequest("onBeforeRequest");
makeRequest("onBeforeSentHeaders");
makeRequest("onSendHeaders");
makeRequest("onHeadersReceived");
makeRequest("onResponseStarted");
makeRequest("onCompleted");
With the console.log above the if, I can see the regex returning true when I want it to and the code making it past the if. When I remove the console.log above the if the if no longer gets executed.
My question is then, how do I get the filtering parameter to work or if that is indeed broken, how can I get the code past the if to be executed? Obviously, this is a fire hose, and to begin searching for a solution I will need to reduce the data.
Thanks
urls must be a string or an array of match patterns. Regular expressions are not supported.
WebRequest.jsm uses resource://gre/modules/MatchPattern.jsm. Someone might get confused with the util/match-pattern add-on sdk api, which does support regular expressions.
I'm currently teaching myself the Dart language, and my first app doesn't seem to be working right. Here's the code that's causing trouble:
usrLoc = int.parse(query("#txtLoc").text);
When I try to run the app, it opens fine, but when I click the button that triggers this (and three other similar parses), the debugger stops and tells me "Source not found" for int._native_parse(), int._parse(), and int.parse().
Any help would be greatly appreciated.
The text property for the specified element #txtLoc returns an empty string.
The parse method requires that:
The source must be a non-empty sequence of base- radix digits, optionally prefixed with a minus or plus sign ('-' or '+').
You can specify an onError named argument in your call to parse, which takes a callback that handles the invalid input. E.g., if you want the parse call to return the value 42 for all invalid input, you can do this:
usrLoc = int.parse(query("#txtLoc").text, onError: (val) => 42);
If you really expect the element to have some text, you can store the result of query("#txtLoc").text into a separate variable and verify the value. It would also be interesting to check what the real element type is or which tag is marked with id #txtLoc.
If you want to get the content of an input element, you should use the value property instead of text:
query("#txtLoc").value
I have a method that displays a validation result using the syntax
Box::info(message,title);
However, the first time I run the code it displays the correct title, but the message refreshEx.
Debugging the code the message that is being used is correct, Valid Account Number, but what displays is refreshEx. If I rerun the process the correct message is displayed, this only happens the first time.
Just in case it matters the flow is
Form - DoValidation method creates Class to call...
Class - public AccountValidation method that calls...
- private displayValidation method that contains this code
Thanks...
I have seen this error (unfortunately), in an AX 2009 installation, launched from code behind a button in a form:
if(HIEItemOrderSetup.RMAvailable < HIEItemOrderSetup.RMQuantity)
{
ok = DialogButton::Ok == box::okCancel("#HIE848",DialogButton::Ok,"#HIE849");
}
As far as I can tell it only occurs when you have a breakpoint on your form, when you are updating it. Removing the breakpoint will show the original message or at least this is what I have found.
If the message contains some fields from the database, try to execute a reread() or refresh() or refreshEx() method (depending on the context) to the datasource before showing the value through the info box.
May be the cached data is not refreshed after an update or insert.
EDIT:
If you are specting a return parameter from an Event, don't forget that this is an async process. An example on MSDN:

If I don't provide the value in the URL for Codeigniter, it'll display a PHP Error was encountered saying it's missing argument for a function call. I do NOT want it displayed at all. If there's no argument in the URL, it should just reroute to its index function. How do I prevent that from happening?
For example, www.example.com/profile/id/45
anyone would guess and enter like this "www.example.com/profile/id"
that would generate the error. How do I prevent that? I tried, "if (!isset($id))" but it generated error before it reached to that condition.
just learned that the solution is simple:
function id($id=NULL)
{
if ($id===NULL)
{
redirect....
}
}
you can also use:
$this->uri->segment(2); // gets 'id'
$this->uri->segment(3); // gets '45'
then do a redirect, check out:
http://codeigniter.com/user_guide/helpers/url_helper.html
use default values for your function
function id($id=0){
if(there any record with $id being provided){
//do something
}else{
//id not provided,set to default values 0 and then
show_404();
}
}
no way there could be id = 0 so its automatically showerror without redirect, if user enter the url www.example.com/profile/id ,
