And this is an example on how to get it from the ID <?php $doc = new DomDocument; $doc->validateOnParse = true; $doc->loadHtml(file_get_contents('http://example.com/bla.php')); var_dump($doc->getElementById('test')); ?> And i have found how to get it from name and NOT ID on the same page <script> function getElements() { var test = document.getElementsByName("test")[0].value; alert(test); } </script> But again I dont know how to get the value of it by name from an external page eg "http://example.com/bla.php", any help?

  • Javascript style variables with "-" in their name aren't able to be changed?

    - by William
    Okay, so this bug has cost me quite a bit of time and embarrassment. It seems that any style variable with a - in it's name can't be modified by javascript. As seen here: <!DOCTYPE html> <html lang="en"> <head> <title>Class Test</title> <meta charset="utf-8" /> <style> body { text-align: center; background-color: #ffffff;} #box { position: absolute; left: 610px; top: 80px; height: 50px; width: 50px; background-color: #ff0000; color: #000000;} </style> <script type="text/javascript"> var box = 0; </script> </head> <body> <div id="box" ></div> <script type="text/javascript"> box = document.getElementById('box'); box.style.background-color = "#0000ff"; </script> </body> </html> The box in said example will just remain red. So how do I change a style variable with a - in it's name?

  • Delete all previous records and insert new ones

  • Ajax return string links not working

    I have this ajax function: function getSearchResults(e) { var searchString = e.value; /*var x = e.keyCode; var searchString = String.fromCharCode(x);*/ if (searchString == "") { document.getElementById("results").innerHTML = ""; return; } var xmlhttp; if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp = new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange = function () { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { document.getElementById("results").innerHTML = xmlhttp.responseText; } } xmlhttp.open("GET", "<%=Page.ResolveUrl("~/template/searchHelper.aspx?searchString=")%>"+searchString, true); xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"); //solve any AJAX caching problem(not refreshing) xmlhttp.send(); } and here is when I call it: <input class="text-input" value="SEARCH" id="searchbox" onkeyup="javascript:getSearchResults(this);" maxlength="50" runat="server" /> and all my links in the searchHelper.aspx file(which retruns them as a string) are like this: <a class="item" href='../src/actors.aspx?id=77&name=dasdassss&type=a' > <span class="item">dasdassss</span></a> When I click this link I want my website to go to ../src/actors.aspx?id=77&name=dasdassss&type=a but nothing happens.

  • Connecting grouped dots/points on a scatter plot based on distance

    - by ToNoY
    I have 2 sets of depth point measurements, for example: > a depth value 1 2 2 2 4 3 3 6 4 4 8 5 5 16 40 6 18 45 7 20 58 > b depth value 1 10 10 2 12 20 3 14 35 I want to show both groups in one figure plotted with depth and with different symbols as you can see here plot(a$value, a$depth, type='b', col='green', pch=15) points(b$value, b$depth, type='b', col='red', pch=14) The plot seems okay, but the annoying part is that the green symbols are all connected (though I want connected lines also). I want connection only when one group has a continued data points at 2 m interval i.e. the symbols should be connected with a line from 2 to 8 m (green) and then group B symbols should be connected from 10-14 m (red) and again group A symbols should be connected (green), which means I do NOT want to see the connection between 8 m sample with the 16 m for group A. An easy solution may be dividing the group A into two parts (say, A-shallow and A-deep) and then plotting A-shallow, B, and A-deep separately. But this is completely impractical because I have thousands of data points with hundreds of groups i.e. I have to produce many depth profiles. Therefore, there has to be a way to program so that dots are NOT connected beyond a prescribed frequency/depth interval (e.g. 2 m in this case) for a particular group of samples. Any idea?

  • How can I measure the time it takes a file to upload to a PHP script?

    - by Gustav Bertram
    I am trying to measure the time a script takes to upload a file to a PHP script, inside the receiving script. Here's a short example: <form action="#" enctype="multipart/form-data" method="post"> Upload: <input type="file" name="datafile" size="40"> <input type="submit" value="Send"> </form> <?php $upload_time = time() - $_SERVER['REQUEST_TIME']; echo $upload_time . " seconds."; I've submitted 4MB, 25MB, 100MB and 1.4GB files. They took anything from a fraction of a second, to almost a minute, yet the script above always yielded 0 seconds. NOTE: I know that this is a duplicate question, but the accepted answer on the other question did not work for me (at least, initially): Detect how long it takes for a file to upload (PHP) I've tried it using PHP 5.3.3 with Apache 2.2.16 on Ubuntu 10.4. UPDATE: I've discovered that both the Apache header and Ajax solutions work. In fact, the solution on the duplicate question also works. The critical element to making these solutions work is to ensure that the following values in the php.ini are sufficiently high: memory_limit = 1000M upload_max_filesize = 1000M post_max_size = 1000M I am accepting the Apache header solution, since it only uses PHP.

  • Trouble swapping values as keys in generic java BST class

    - by user1729869
    I was given a generic binary search tree class with the following declaration: public class BST<K extends Comparable<K>, V> I was asked to write a method that reverses the BST such that the values become the keys and keys become values. When I call the following method (defined in the class given) reverseDict.put(originalDict.get(key), key); I get the following two error messages from Netbeans: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: BST.put And also: no suitable method found for put(V,K) method BST.put(BST<K,V>.Node,K,V) is not applicable (actual and formal argument lists differ in length) method BST.put(K,V) is not applicable (actual argument V cannot be converted to K by method invocation conversion) where V,K are type-variables: V extends Object declared in method <K,V>reverseBST(BST<K,V>) K extends Comparable<K> declared in method <K,V>reverseBST(BST<K,V>) From what the error messages are telling me, since my values do not extend Comparable I am unable to use them as keys. If I am right, how can I get around that without changing the class given (maybe a cast)?

  • How can I qualify an autowired property with a variable from a config file using annotations?

    - by jiggy
    My specific problem is that I have configured two beans that implement the same interface and I have a third bean that has a property of that interface's type. I inject the property using a config property. So, assuming RemoteDataSource and LocalDataSource implement IDataSource and dao1 has a property of type IDataSource, my XML config might look like this: <bean id="datasource1" class="com.foo.RemoteDataSource"> <property name="url">${url}</property> </bean> <bean id="datasource2" class="com.foo.LocalDataSource"> <property name="path">${filepath}</property> </bean> <bean id="dao1" class="com.foo.MyDAO"> <property name="dataSource">${datasource}</property> </bean> With url, filepath and datasource being defined in an included properties file. We are now making a push for annotation-driven configuration and I'm not sure how to annotate my dao to put the data source configured in the property file. I want to do something like this, but it is evidently not allowed: @Autowired @Qualifier("${datasource}") public void setDataSource(IDataSource datasource) {...}

  • Java: over-typed structures?

    - by HH
    Term over-type structure = a data structure that accepts different types, can be primitive or user-defined. I think ruby supports many types in structures such as tables. I tried a table with types 'String', 'char' and 'File' in Java but errs. How can I have over-typed structure in Java? How to show types in declaration? What about in initilization? Suppose a structure: INDEX VAR FILETYPE //0 -> file FILE //1 -> lineMap SizeSequence //2 -> type char //3 -> binary boolean //4 -> name String //5 -> path String Code import java.io.*; import java.util.*; public class Object { public static void print(char a) { System.out.println(a); } public static void print(String s) { System.out.println(s); } public static void main(String[] args) { Object[] d = new Object[6]; d[0] = new File("."); d[2] = 'T'; d[4] = "."; print(d[2]); print(d[4]); } } Errors Object.java:18: incompatible types found : java.io.File required: Object d[0] = new File("."); ^ Object.java:19: incompatible types found : char required: Object d[2] = 'T'; ^

  • Accessing derived class members with a base class pointer

OR If it's not possible that way, what would be a better way?

  • In Ruby or Python can the very idea of Class be rewritten?

    - by John Berryman
    Howdy All... first time at stack overflow. I'm looking into using some of the metaprogramming features provided by Ruby or Python, but first I need to know the extent to which they will allow me to extend the language. The main thing I need to be able to do is to rewrite the concept of Class. This doesn't mean that I want to rewrite a specific class during run time, but rather I want to make my own conceptualization of what a Class is. To be a smidge more specific here, I want to make something that is like what people normally call a Class, but I want to follow an "open world" assumption. In the "closed world" of normal Classes, if I declare Poodle to be a subclass of Dog to be a subclass of Animal, then I know that Poodle is not going to also be a type of FurCoat. However, in an open world Class, then the Poodle object I've defined may or may not be and object of type FurCoat and we won't know for sure until I explain that I can wear the poodle. (Poor poodle.) This all has to do with a study I'm doing concerning OWL ontologies. Just so you know, I've tried to find information online, but due to the overloading of terms here I haven't found anything helpful. Super thanks, John

  • Merging ILists to bind on datagridview to avoid using a database view

    - by P.Bjorklund
    In the form we have this where IntaktsBudgetsType is a poorly named enum that only specifies wether to populate the datagridview after customer or product (You do the budgeting either after product or customer) private void UpdateGridView() { bs = new BindingSource(); bs.DataSource = intaktsbudget.GetDataSource(this.comboBoxKundID.Text, IntaktsBudgetsType.PerKund); dataGridViewIntaktPerKund.DataSource = bs; } This populates the datagridview with a database view that merge the product, budget and customer tables. The logic has the following method to get the correct set of IList from the repository which only does GetTable<T>.ToList<T> public IEnumerable<IntaktsBudgetView> GetDataSource(string id, IntaktsBudgetsType type) { IList<IntaktsBudgetView> list = repository.SelectTable<IntaktsBudgetView>(); switch (type) { case IntaktsBudgetsType.PerKund: return from i in list where i.kundId == id select i; case IntaktsBudgetsType.PerProdukt: return from i in list where i.produktId == id select i; } return null; } Now I don't want to use a database view since that is read-only and I want to be able to perform CRUD actions on the datagridview. I could build a class that acts as a wrapper for the whole thing and bind the different table values to class properties but that doesn't seem quite right since I would have to do this for every single thing that requires "the merge". Something pretty important (and probably basic) is missing the the thought process but after spending a weekend on google and in books I give up and turn to the SO community.

  • Jquery.Validate plugin + realPerson plugin

    - by Dave Watts
    I can't figure out how to make it so the form wont fire unless the realPerson captcha is "valid". I can see that when the user types in the correct/valid letters and clicks submit it adds a class of "valid" to the input. So Ive been trying to figure out how to get the jquery.validate plugin to only fire when the class "valid" is present. <script type="text/javascript"> $(document).ready(function(){ $('#defaultReal').realperson(); $('#contact_form2').validate({ submitHandler: function(form) { var str = $("form").serialize(); $.ajax({ type: "POST", url: "contactpage.php", data: str, success: function(){ $('#contact_form2').html("<div id='message'></div>"); $('#message').html("<h2>Contact Form Submitted!</h2>") .append("<p>We will be in touch soon.</p>") .hide() .fadeIn(1500, function() { $('#message').append("<img id='checkmark' src='images/check.png' />"); }); }}); return false; } }); Thank you in advanced! -Dave

  • How to replace auto-implemented c# get body at runtime or compile time?

    - by qstarin
    I've been trying to figure this out all night, but I guess my knowledge of the .Net Framework just isn't that deep and the problem doesn't exactly Google well, but if I can get a nod in the right direction I'm sure I can implement it, one way or another. I'd like to be able to declare a property decorated with a custom attribute as such: public MyClass { [ReplaceWithExpressionFrom(typeof(SomeOtherClass))] public virtual bool MyProperty { get; } } public SomeOtherClass : IExpressionHolder<MyClass, bool> { ... } public interface IExpressionHolder<TArg, TResult> { Expression<Func<TArg, TResult>> Expression { get; } } And then somehow - this is the part I'm having trouble figuring - replace the automatically generated implementation of that getter with a piece of custom code, something like: Type expressionHolderType = LookupAttributeCtorArgTypeInDeclarationOfPropertyWereReplacing(); return ReplaceWithExpressionFromAttribute.GetCompiledExpressionFrom(expressionHolderType)(this); The main thing I'm not sure how to do is replace the automatic implementation of the get. The first thing that came to mind was PostSharp, but that's a more complicated dependency than I care for. I'd much prefer a way to code it without using post-processing attached to the build (I think that's the jist of how PostSharp sinks its hooks in anyway). The other part of this I'm not so sure about is how to retrieve the type parameter passed to the particular instantiation of the ReplaceWithExpressionFrom attribute (where it decorates the property whose body I want to replace; in other words, how do I get typeof(SomeOtherClass) where I'm coding the get body replacement). I plan to cache compiled expressions from concrete instances of IExpressionHolder, as I don't want to do that every time the property gets retrieved. I figure this has just got to be possible. At the very least I figure I should be able to search an assembly for any method decorated with the attribute and somehow proxy the class or just replace the IL or .. something? And I'd like to make the integration as smooth as possible, so if this can be done without explicitly calling a registration or initialization method somewhere that'd be super great. Thanks!

  • Simple search form passing the searched string through GET

    - by Brian Roisentul
    Hi, I'd like my Search form to return the following url after submit: /anuncios/buscar/the_text_I_searched My form is the following: <% form_for :announcement, :url => search_path(:txtSearch) do |f| %> <div class="searchBox" id="basic"> <%= text_field_tag :txtSearch, params[:str_search].blank? ? "Busc&aacute; tu curso r&aacute;pido y f&aacute;cil." : params[:str_search], :maxlength=> 100, :class => "basicSearch_inputField", :onfocus => "if (this.value=='Busc&aacute; tu curso r&aacute;pido y f&aacute;cil.') this.value=''", :onblur => "if(this.value=='') { this.value='Busc&aacute; tu curso r&aacute;pido y f&aacute;cil.'; return false; }" %> <div class="basicSearch_button"> <input type="submit" value="BUSCAR" class="basicSearch_buttonButton" /> <br /><a href="#" onclick="javascript:jQuery('#advance').modal({opacity:60});">Busqueda avanzada</a> </div> </div> <% end %> My routes' line for search_path is this: map.search '/anuncios/buscar/:str_search', :controller => 'announcements', :action => 'search' Well, this will work if I manually type the url I want in the brower, but definitely, if you look at the form's url, you'll find a ":txtSearch" parameter, which is not giving me the actual value of the text field when the form is submitted. And that's what I'd like to get! Could anybody help me on this?

  • Why does fb:fan control disappear after login with requireSession on external page?

    - by Max
    Hi, Reqs: I want to make an external page with a 'Become a Fan'-button. I want users to login to facebook once they open the page (this is because of other features in the site) So I call FB.Connect.requireSession once the page loads, and put a <fb:fan></fb:fan> control on the page. Then when I open the page I see the 'Connect with Facebook to Continue' pop-up and a small 'Become a fan' button. This seems right. When I log in to Facebook using the pop-up the 'Become a fan button' disappears!! Can anyone explain this weird behaviour or does someone know a way to reach my requirements in a different way. Below you can see my code. Thanks in advance! <!-- Head --> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/nl_NL" type="text/javascript"></script> <script type="text/javascript"> var fbApiKey = "MY_KEY"; var fbXdReceiver = "xd_receiver.htm"; function fbLoad() { FB.init(fbApiKey, fbXdReceiver); FB.ensureInit(function() { FB.Connect.requireSession(null, null, false); }); } </script> <!-- Body onload="fbLoad();" --> <fb:fan profile_id="24932281961" name="Nutella" id="fanButton" stream="0" connections="0" logobar="0" width="250"></fb:fan>

(y/n)') db.close() I has manually deleted records from table and than run script two times. See https://dpaste.de/MwMa . I think, that rollback in my code doesn't work. Why?
