  • Get Checked RadioButtons using JavaScript

    - by Rudi
    so I’m trying to build a win 8 app, which includes a WebView. The WebView contains the HTML code (+JavaScript) below. <!DOCTYPE HTML PUBLIC " -//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <?xml version='1.0' encoding='UTF-8' standalone='yes'?> <html> <head> <meta http-equiv='Content-Type' content='text/html; charset=utf-8' > <script type='text/javascript'> function get_radio_value() { for (var i=0; i < document.myForm.frage1.length; i++) { if (document.orderform.frage1[i].checked) { var rad_val = document.myForm.frage1[i].value; return rad_val; } } } </script> <title>Kundenfragebogen</title> </head> <body> <h1>Kundenfragebogen</h1> <div id='myDiv'>Hello</div> <form name='myForm' action=''> <table border='2'> <tr> <td></td> <td>sehr gut</td> <td>gut</td> <td>schlecht</td> </tr> <tr> <td>Wie geht es Ihnen?</td> <td><input type='radio' name="frage1" value='1'/>Mir ging es noch nie besser!</td> <td><input type='radio' name="frage1" value='2'/>Es geht mir so wie immer.</td> <td><input type='radio' name="frage1" value='3'/>Heute geht einfach gar nichts…</td> </tr> <tr> <td>Können Sie Auto fahren?</td> <td><input type='radio' name="frage2" value='1'/>Ja</td> <td></td> <td><input type='radio' name="frage2" value='3'/>Nein</td> </tr> <tr> <td>Möchten Sie unseren Newsletter abonnieren?</td> <td><input type='radio' name="frage3" value='1'/>Ja</td> <td></td> <td></td> </tr> </table> <input type='button' value='Formular absenden' onclick="return get_radio_value()"/> </form> </body> </html> So the html contains some radio buttons and a button. I’ve used JavaScript ~2 years ago (just a little), so I don’t really know how to write the exact code. I’ve found something on the internet, but it doesn’t do what I want. I want to have the following: The user can check the RadioButtons. When the user clicks the Button, the JavaScript function should return all the checked radio buttons (I only need to know which RadioButton is checked). Since I know the name of the RadioButtons in my Windows 8 App, I can do the following: var object = WebView.InvokeScript("JavaScriptFunctionNAME", NameOfRadiobutton); So the WebView invokes the script and should get as a return the VALUE of the RadioButton, which is checked. “JavaScriptFunctionNAME” = name of the function in Javascript NameOfRadiobutton = the name of the RadioButton as a parameter (for example “frage1”). Currently I’m returning the value of the radiobutton, which is checked in the RadioGroup “frage1”. How can I check every RadioButton by it’s parameter? By this I mean I have a parameter “frage1” and return the value of the checked RadioButton. After this, I call the function again with the parameter “frage2” and return the checked RadioButtons value. Could anyone help me out with the JavaScript-function?

  • Get data from html form to ruby in Ruby on Rails

    - by Maestro1024
    Get data from html form to ruby in Ruby on Rails I have some html like this <html> <h1>Text to PDF</h1> <textarea name="comments" cols="40" rows="5"> Enter your Text here... </textarea><br> <input type="submit" value="Submit" /> </form> </body> </html> I want to give the value of the text into the controller for this page/view. How do I do this with rails? I am new to rails, what is the mechanism for this? I don't need to write to the database just want to hand it to the controller. If there is a good tutorial for this sort of thing that would be great, I am not convince I am approaching this correctly.

  • Parsing HTML "Visually"

    - by Midhat
    OKay I am at loss how to name this question. I have some HTML files, probably written by lord Lucifier himself, that I need to parse. It consists of many segments like this, among other html tags <p>HeadingNumber</p> <p style="text-indent:number;margin-top:neg_num ">Heading Text</p> <p>Body</p> Notice that the heading number and text are in seperate p tags, aligned in a horizontal line by css. the css may be whatever Lucifier fancies, a mixture of indents, paddings, margins and positions. However that line is a single object in my business model and should be kept as such. So How do I detect whether two p elements are visually in a single line and process them accordingly. I believe the HTML files are well formed if it helps.

Stuff Im suspecting: Should i be using jsonp instead of json? Im new to this. Is there a problem with my php file? Perhaps I need to include some more javascript files in my html file? I assume this is a very simple problem so please help me out! I think there is just some conceptual error, as i have only just started with jquery, ajax, and json. Thank you.

  • Can a Javascript bookmarklet overlay an image on a web page?

    - by songdogtech
    Can a bookmarklet be used to overlay an image on a web page? Not as a pop-up, but as a image positioned by CSS and with a high z-index to display on top of other elements. And without a mask i.e., Shadowbox or similar jQuery effect. Just an image from a URL and positioned in the bottom left hand corner of the browser window. This is what I have so far, but it may be the wrong direction to be going: javascript:(function(){document.write("body {background-image:url(http://mydomain.com/image.png); position: absolute; left:50px; top:300px; z-index:9999;}");})() I have a JS function that works as a bookmarklet to change the case of text on the page, and now I'd like to be able to show an image when the bookmarklet is used.

  • How to name uploaded files in php to prevent them from being overwritten?

    - by user156814
    I'm trying to add user submitted articles to my website, (only for admins). With each article comes an option to upload up to 3 images. My database is set up like this Articles id user_id title body date_added last_edited Photos id (auto_increment) article_id First I save the article in the database, then I upload the photo (temporarily) then I create a new photo record in the database saving the article_id. Then I rename the uploaded photo to be the same as the primary key of the photo record, and to be a png. $filename = $photo->id . '.png'; I figured this would be a good way to prevent files form being overwritten. This seems flawed to me. Any suggestions on how I should save my records and photos? Thanks

But if I upload to the server and open from there, the div is hidden underneath his parent. I've tried several z-index combinations and none works. Here's the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>Test</title> <meta http-equiv="content-type" content="text-html; charset=utf-8" /> <style type="text/css"> .col { float:left; width:310px; margin-right:13px; } .art { position:relative; border-bottom: 1px solid #d0d0d0; font: normal normal bold 11px Arial,Verdana,Helvetica; color:#A0A0A0; width:310px; height:50px; top:0px; left: 0px; margin-right:10px; background-color:#F0F0F0; } .art a { padding:3px; display:block; width:304px; height:100%; color:#707070; } .art a:visited { color:#A0A0A0; } .art a:hover { background-color:#E0E0E0; } .box { z-index:1000; background-color:#A0A0A0; color:#404040; font: normal normal bold 11px Arial,Verdana,Helvetica; display:none; position:absolute; top:30px; left:10px; text-align:left; border:3px solid #707070; margin:5px 0px 5px 5px; font-size:10px; color:White; width:100%; } </style> <script type="text/javascript"> function sh(obj) { var el = document.getElementById(obj); if ( el.style.display != 'block' ) { el.style.display = 'block'; } else { el.style.display = 'none'; } } </script> </head> <body> <div class="col"> <div class="art"> <a href="" target="_blank" onmouseover="javascript:sh('i0')" onmouseout="javascript:sh('i0')">Title 1</a> <div id="i0" class="box"> <div class="text"> Les "chemises rouges" manifestent depuis la mi-mars pour faire tomber le gouvernement et occupent depuis trois semaines un quartier touristique et commerçant autour duquel ils ont érigé des barricades. </div> </div> </div> <div class="art"> <a href="" target="_blank" onmouseover="javascript:sh('i1')" onmouseout="javascript:sh('i1')">Title2</a> <div id="i1" class="box"> <div class="text"> Une association ardéchoise accueillant des séminaires de "bien-être" et de "développement personnel" a refusé d'accueillir un stage de danse en invoquant l'homosexualité des participants, ont indiqué aujourd'hui les organisateurs. </div> </div> </div> </div> </body> </html> What's is going on here?

  • Including associations optimization in Rails

    - by Vitaly
    Hey, I'm looking for help with Ruby optimization regarding loading of associations on demand. This is simplified example. I have 3 models: Post, Comment, User. References are: Post has many comments and Comment has reference to User (:author). Now when I go to the post page, I expect to see post body + all comments (and their respective authors names). This requires following 2 queries: select * from Post -- to get post data (1 row) select * from Comment inner join User -- to get comment + usernames (N rows) In the code I have: Post.find(params[:id], :include => { :comments => [:author] } But it doesn't work as expected: as I see in the back end, there're still N+1 hits (some of them are cached though). How can I optimize that?

  • Jquery draggable with zoom problem

    - by Manuel
    I am working on a page in witch all its contents are scaled by using zoom. The problem is that when I drag something in the page the dragging item gets a bad position that seems relative to the zoom amount. To solve this I tried to do some math on the position of the draggable component, but seems that even tho visually its corrected, the "true" position its not recalculated. here is some code to explain better: var zoom = Math.round((parseFloat($("body").css("zoom")) / 100)*10)/10; var x = $(this).data('draggable').position; $(this).data('draggable').position.left = Math.round(x.left/zoom); $(this).data('draggable').position.top = Math.round(x.top/zoom); Any help would be greatly appreciated

    - by Tom Hutchinson
    I'm new to CSS and this issue in Visual Studio is driving me mad!

  • Rails: translate ActiveRecord error template headers for a single model

    - by Chris
    Hi, I'm trying to rename the authlogic error messages in a Rails 3 app. The general format I found out working in Rails 3: de: errors: template: header: one: "Konnte {{model}} nicht speichern: ein Fehler." other: "Konnte {{model}} nicht speichern: {{count}} Fehler." body: "Bitte überprüfen Sie die folgenden Felder: But I want to change this for the authlogic user session model (and only for this one) because when the Login fails, the message "Could not save user session" does not make very much sense. How can I do that?

  • Opening a new screen from xml file text.

    - by Clozecall
    Hey all I'm looking to edit my app so that when a text within an xml file is selected, a new window opens. I've found various ways of making a new screen open via a class, but I need it done from a xml file. My program as a tablayout, and here is some of the stuff displayed within my first tab: <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> android:id="@+id/ScrollView01" android:layout_height="wrap_content" android:layout_width="fill_parent" <TextView android:textColor="#FFFFFF" android:text="First Header here" android:textStyle="bold" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <TextView android:textColor="#FFFFFF" android:text="First body text here" android:layout_width="fill_parent" android:layout_height="wrap_content" /> So basically I need it so that when a text is selected, a new screen pops up. As said the reason this specifically has to be done in xml is because this is all apart of a tab layout, It would be great if the next within each tab could open a a new screen. Thanks.
