Here is the website I am trying to access. I dont want the default tab (Day) though, I want to select the Season tab
https://www.eex.com/en/market-data/power/futures/uk-financial-futures#!/2017/05/23
The link appears to be exactly the same whichever tab is chose making differentiation impossible as far as I can tell.
Any help on this would be much appreciated, using whichever programming method and language is appropriate.
Kind Regards

The URL does not change since this is an ajax request, which you can see from MarketDataTableAController's getPageData function. You can read about them here https://developer.mozilla.org/en-US/docs/AJAX/Getting_Started
Ive inspected your html and you seem to be using angular. On further inpection you can see that the tabs have ng-click="setActiveTab(tab)" attribute on them. So whenever user clicks, this function gets executed. It is a matter of using this function with the appropriate tab object to get the content to change. You for example could put setActiveTab(tab) into your controller init method since setActiveTab() calls the forementioned getPageData() function to update the page.
Also the tab you are looking for is page.tabs[5] ($parent.page.tabs[5] if referring from TabController) since this is the tab with the label of season. Pass that to setActiveTab() and it should show you the season instead.
However this might not be a good solution since the tab array ordering might change. Then you would need to loop over all objects in page.tabs and see if tab.label === "Season" and pass that in the function instead or better yet use the $filter service provided by angular which would look more cleaner.
Your code source also seems to be minimized and its not very easy to read.

I was working out a problem with a ddl trying to get a message box to popup when the item changed. You can read about that here >>>
How to Popup Alert() from asp:DropDownList OnSelectedIndexChanged?
The working answer shows me to use the onchange event but then I'm working in VS2010 this event does not appear in the intellisense dropdown. However if I type it in anyway it works fine.
For this, you need to understand how the thing works....when you change the value of a input element, onchange event gets triggered on the browser, so the browser looks for a way to handle it. So when you put the onchange event specified for the element it gets called.
Now, ASP.NET OnSelectedIndexChanged uses the same functionality(logically saying) to POST the page to the server. From there, the ASP.NET runtime triggers the function you wrote in the codebehind file and returns you the result. Now, if you really don't require any operation that can only happen on the server, you don't need to use the server functionality, instead you can do it in javascript.
On the other hand, if you want something that happens on server: like some database get, you are supposed to use the OnSelectedIndexChanged event.
And if you use the OnSelectedIndexChanged event, you can still call some javascript functions from there.
Page.ClientScript.RegisterClientScriptBlock(typeof(string),"myScript","alert('HI')",true);
To answer your question about intellisense, onchange is a event of input types, and in aspx pages, i guess you are using <asp:..> tags, which does not have the same event - thus visual studio does not show it in the intellisense. But when you put it, it gets assigned to the HTML markups, which is interpreted correctly by the browser.
PROS and CONS
onchange works on your browser, so it is lot faster than the server-side code. On the other hand, we had an issue once that the browsers has the capability to restrict pop-ups. So if you want some really important message to be shown, it is better to use the Server-Side event and the RegisterClientScriptBlock function.
Hope it helps.
I am trying to call a page in my customers webapplication (Exact Synergy Enterprise)
This is the link: http://someserveridontdisclose/Synergy/docs/CSCANEduCourseCard.aspx?ProjectNr=ACPGINTV
Within this page is an Ajax TabContainer with several TabPanels. One of them is called 'Doelgroepen'
I dont have the source for this application, as i am not the developer of it. We only develop custom extentions to it.
Here's the question: Is it possible to focus on one of the tabs USING ONLY AN URL? If so How?
Thank you very much for your thoughts about this.
try to set with javascript. you'll have to write your own js to get index number you want from url, then set like this
$find('<%=TabContainer1.ClientID%>').set_activeTabIndex(2);

If you do not have access to the code and if this is not part of the requirement / design specification for the application you are using (ie: what you asked the developer to do), then the answer is No.
The control does not have "native" support for URL tab selection. There needs to be specific code in the application in order to handle this.
It is however very easy to implement, if you absolutely need it, it shouldn't take much time (about 15-30 lines of code, depending on how many tabs/urls combination you need).
You can find a running sample of the AjaxControlToolkit Tabs control at the following link (the available functionnalities are described in there):
http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/Tabs/Tabs.aspx
If the TAB has an ID you could make it visible by adding '#tabid' to the URL.
I have a web application for tagging data and viewing data by tag, so my UI is a list of checkboxes for each tag, a list of checkboxes for each data item, a "Tag" button, which adds the checked tags to the checked data, and a "Filter" button, which ignores the checked data and just displays only the data items with the given tag.
My problem is that the former operation (tagging data) is "obviously" a POST operation, whereas the latter operation (viewing data according to a tag) is "obviously" a GET operation. But the method attribute is attached to the form, not the submit button, so I have to choose one or other for both buttons.
I don't want to make two forms, since as far as I can tell this would force me to duplicate the entire tag list. Is there any way I can choose my method based on the choice of submit button?
A JavaScript solution is permissible, but one without would be preferred.
(I am going to post an answer to this question, but I don't particularly like it, so I would welcome alternatives).
In principle, you could use the formmethod attribute in a submit button, as per HTML5. However, it is not recognized by IE, even in IE 9. The existence of the feature in HTML5 indirectly proves that previous versions of HTML lack a feature for this.
On the other hand, the POST method can be used even for simple viewing that does not cause any changes in the outside world, and in many situations it has to be used for technical reasons (e.g., too much data). So I think the method issue is not very relevant; just use POST.
I would honestly go with a javascript solution, in the onsubmit of the form fire a method which a) checks the submit button that was pressed and b) based on this changes the method of the form.
One possible solution would be to use POST, and then have the server give a 303 See Other header to change it into a GET request. This involves making two requests to serve the purpose of one, which is unfortunate, but at least means that the URL will change so people can link to a specific tag selection.
I agree with javascript solution, proposed by Jon Taylor, the problem is not if your form's method is GET or POST, but how do you filter/validate/sanitize user input. If your concern is related to the fact, that the user can manipulate the form's method, then you should implement solution to that matter on server side.
Assume I have a html from, and it contain some submit type. I want to create a "are you sure" popup window that will appear when user click submit button.
My question is that is there any way to create it by using "only" html, not using javascript or any other?
HTML only is possible, but not without a postback
Scenario that could work without javascript:
You have your form with submit button
User clicks (and submits) the form
You display another form with are you sure? form (that contains Yes and No buttons as well as hidden fields of the first form that will make it possible to do the action required on the original data
functionality that executes the action and goes back to whatever required.
This would be completely Javascript free, but it would require several postbacks.
This kind of thing is usually done on the client with a Javascript confirm() function (here's a simple example) or lately with a more user friendly modal dialog provided by many different client libraries or their plugins.
When to choose the script free version?
If you know your clients are going to be very basic ones (ie. vast majority of your users will access your application using clients like Opera Mini that's not able to run scripts at all). But in all other cases it's much better to do this using Javascript. It will be faster, easier to develop and much more user friendly. Not to mention that it will put less strain on your server as well since certain parts will execute on the client without the need of any server processing.
No, there isn't. Despite of the new features in HTML 5, HTML is still a markup language, not a programming language. In order to express dynamic behavior (such as an "are you sure?" box), you need to use a programming language.
Javascript would be the most obvious choice for this, but you could also do it with frameworks that can get you around writing Javascript by hand (for example ASP.NET).
Edit: Actually it appears that it would theoretically possible to do this with without Javascript or other frameworks. As I just learned, HTML 5 + CSS 3 seems to be turing complete. But this is hardly relevant to this question.
It's possible to ask for a confirmation, but it will not be in a "popup window". The creation of the "popup window" requires javascript/other language.
It will be:
Request (first form)
POST
Response (confirmation form)
POST
Response (outcome message)
You can create a form with all hidden elements containing the data from the first form and a "Yes" and "No" button below the "Are you sure?" text. You can use PHP sessions to avoid the hidden form elements. If there is a lot of data or confidential data or you do not want to re-validate the data from the second form, use sessions. Make sure you validate the data from either form before using it.
I know I'm like .. 10 years late. But for anyone still wondering I thought I could be of some help!
What I did for this exact problem was make sure I had multiple "divs" in my code. For me specifically, I had two main ones.
First, one whose id="main", and another whose id="popup" with the 'visible' property initially set to 'false' for the popup div.
Then, on whichever event you're looking for (button click for example) you'll simply set main.Visible = false and popup.Visible = true, then you could have more buttons in your popup (yes, no, cancel, confirm, etc.) which do the exact same thing, but in reverse!
The most important thing to make sure of is that you have the 'runat="server"' property in your divs so that you can access them in your CS code
Hope this was helpful! :)
I'm wracking my brain on this one.
After an HTML document loads in a browser, I want to be able to monitor
the page in case any content on it changes for any reason.
Is there a Javascript function with which I can track 'what has
changed' on the webpage. This should be irrespective of the type of content on the HTML page.
I have two examples for you to ponder on:
Ex1:
Say in an HTML document there are two select boxes s1 and s2.
The items list in s2 depends on selections in s1 (page is not
refreshed — that is, s2 is loaded through Ajax or something).
So after the HTML page loads I need to get a notification whenever s2
is populated...
Ex2:
Say, in an HTML page, there's a link, Onclicking which a light pop-up
div is created with some text.
How can I capture the content of this dynamic pop-up?
In all this discussion, I'm not taking into account any particular
format of HTML...the HTML content can be anything...I just need
to keep tracking if any content changes after the page loads...
Ideally I need to achieve this using JavaScript (client-side
scripting).
How can I achieve this?
You can keep track of changes in a textbox using onkeyup. This will tell you every time someone makes a change in a given textbox.
This could potentially fire alot of events. However, using onblur won't necessarily tell you about changes in the textbox and onchange's browser coverage is spotty at best.
If you are using AJAX, you could setup the response function to handle a home grown "event listening" system. So after the response does what it needs to do, it could call any methods that were registered with it, passing in the response text when necessary.
So from your examples above, in Ex1, when the AJAX returns from S1, it would load S2, then call a method saying S2 had changed. In Ex2, when the new AJAX returns the DIV's contents, after loading it into the DIV, it call a different method (or possibly the same depending on what your trying to do) and alerts it that the DIV has new contents.
You could set your "watcher" script as a timer, running a diff function on the current document.body.innerHTML and a stored version captured on load. Depending on how fast the diff will run will give you an idea on what timer interval to use.
This may not capture changes in form elements, but for those, it's easier to loop through all form elements in every form on the page.
Here's someone's diff function I found on Google: http://snowtide.com/jsdifflib
