  • Display x if x display y if y (bad title I know)

    - by user1914940
    Ok so after reading the title you are most likely like...what? Ok, so I have a jquery code that displays input box if an item with prefix Blue from dropdown menu is selected. Code: $(function() { $('#text1').hide(); $('#select2').on('change', function(event) { var opt = this.options[ this.selectedIndex ]; var picked_blue = $(opt).text().match(/Blue/i); if(picked_blue) { $('#text1').show(); } else { $('#text1').hide(); } }); }); But what I also need to add is to display something else if any other item from dropdown menu is selected.

  • jQuery: Load body of page into variable

    - by Nathan G.
    I'm using jQuery to load the result of a PHP script into a variable. The script is passed something that the user typed with a GET request. I want to take just what the script spit out into its <body> tag. Here's what I've tried: JS: function loader() { var typed = $('#i').val(); //get what user typed in $.get("script.php", {i: typed}, function(loaded) {dataloaded = loaded;}); alert($(dataloaded).find('body')) } But it just displays [Objec object]. How can I get a useful value that is just the contents of the body of a loaded page? I know the PHP works, I just need the JS. The script echos something like 1!!2 (two numbers separated by two exclamation points). Thanks!

  • Replace Emails and HREFS with enclosing HREFS

    - by Nissan Fan
    I have an Email body that used to be plain text, but now I've made it HTML. The emails are generated using a number of methods and none of them are easy to convert. What I have is: Some content [email protected], some http://www.somewebsite/someurl.aspx. What I'd like to do is create a function that automatically encloses all email addresses and all URLs within a string in HREF tags so that the HTML email reads properly in all email clients. Does anyone have a function for this?

  • putting data from a for loop into a table using matlab and fprintf

    - by user2928537
    I am trying to put the following data from my for loop into a table formatted so that there are 11 values of F in each column, with a total of 4 columns. but I am always ending up with one long column of my data instead of the four columns I want. I was wondering if there is some way to put the data into a matrix and then reshape it, but I am having trouble. Any help greatly appreciated. fprintf ('Electrostatic Forces:\n') for r = 1:4; q2 = 0: 1*10^-19: 1*10^-18; for F = coulomb(q2,r); fprintf ('%d\n',F) end end Where the code for the function coulomb is function F = coulomb (q2,r); k = 8.98*10^9; q1 = 1.6*10^-19; F = k*abs(q1*q2)/r^2; end

  • beforeSave() returned some error

    - by kwokwai
    Hi all, I got a simple input text field in a HTML form: <input type="text" name="data[User][pswd]" id="data[User][pswd]"> The scripts for the Controller's action that captured the data is as follows: function register(){ $temp = $this->data; if(strlen($temp['User']['pswd'])>6) { if ($this->User->save($this->data)) { $this->Session->setFlash('Data was Saved'); } } } // this script works And in the Model controller, I got these lines of codes: function beforeSave() { $raw = $this->data; if(strlen($raw['User']['pswd'])>6){ md5($raw['User']['pswd']); } return true; } // this script failed to work The data was stored into the Database successfully but it was not undergone any MD5 encryption. I think that there must be some errors in the Model's script because I saw some errors flashed after the data was saved, but the screen that showed the errors immediately refreshed in a second after the data was saved successfully and I couldn't see the detail of the errors that caused the problem. Could you help me out please?

  • Javascript: Retrieve Object Property Names

    - by Jason
    I'm trying to write a function that needs to know the property names of an object being passed in, like so: var data = { "key1":"value1", "key2":"value2", etc} ^ i want the string value "key1" How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in. If that doesn't make sense I suppose I could try to explain more. Thanks! I eventually want to do something like: for (var i = 0; i<data.length; i++) { var name = data[i].getPropertyName() <--- not a real function // do stuff }

  • Struct like objects in Java

    - by cdv
    Is it completely against the Java way to create struct like objects? class SomeData1 { public int x; public int y; } I can see a class with accessors and mutators being more Java like. class SomeData2 { int getX(); void setX(int x); int getY(); void setY(int y); private int x; private int y; } The class from the first example is notationally convenient. // a function in a class public int f(SomeData1 d) { return (3 * d.x) / d.y; } This is not as convenient. // a function in a class public int f(SomeData2 d) { return (3 * d.getX()) / d.getY(); }

  • What is an alternative to eval in this situation?

    - by CppLearner
    Many of my view functions do similar things. For the most part, they reverse to a different views upon clicking a button / a text link. So I wrote a helper function render_reverse def render_reverse(f, args): # args are all string type return eval('reverse(' + f + ', ' + args + ')' ) eval is a bad practice, and is pretty slow. It takes 3 seconds to start redirecting, whereas calling reverse directly takes less than 1 second to start redirecting. What alternative do I have? By the way, the function above doesn't work properly. I was modelling after this line (which works) eval('reverse("homepage", args=["abcdefg"])') Thanks.
