  • Pass data from one form to another on a seperate page

    - by Micanio
    I am building a price/distance calculator with Google Maps API and am trying to pass the info from the calculator to a booking form on a separate page. My first form has 2 submit buttons - one to make the calculation, and one to submit the relevant data to the booking form. I'm stuck trying to make the 2nd button work. Once the API calculation has been made, I get 4 values - From, To, Cost, Distance. I am trying to pass the From, To and Cost values into my booking form by clicking the second button. But I can;t seem to get it to work. I've tried POST and GET but I think I may have been doing something wrong with both. Any help is appreciated. Code for API form: <script type="text/javascript" src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIAAAAwCUxKrPl8_9WadET5dc4KxTqOwVK5HCwTKtW27PjzpqojXnJORQ2kUsdCksByD4hzcGXiOxvn6C4cw&sensor=true"></script> <script type="text/javascript"> var geocoder = null; var location1 = null; var location2 = null; var gDir = null; var directions = null; var total = 0; function roundNumber(num, dec) { var result = Math.floor(num*Math.pow(10 ,dec))/Math.pow(10,dec); return result; } function from(form) { address1=form.start.options[form.start.selectedIndex].value form.address1.value=address1 form.address1.focus() } function to(form) { address2=form.end.options[form.end.selectedIndex].value form.address2.value=address2 form.address2.focus() } function initialize() { var map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(54.019066,-1.381531),9); map.setMapType(G_NORMAL_MAP); geocoder = new GClientGeocoder(); gDir = new GDirections(map); GEvent.addListener(gDir, "load", function() { var drivingDistanceMiles = gDir.getDistance().meters / 1609.344; var drivingDistanceKilometers = gDir.getDistance().meters / 1000; var miles = drivingDistanceMiles.toFixed(0); //var cost = (((miles - 1) * 1.9) + 3.6).toFixed(2); var meters = gDir.getDistance().meters.toFixed(1); if(miles < 70){ var cost = miles *1.75; } if(miles >70){ var cost = miles *1.2; } document.getElementById('from').innerHTML = '<strong>From: </strong>' + location1.address; document.getElementById('to').innerHTML = '<strong>To: </strong>' + location2.address; document.getElementById('cost').innerHTML = '<span class="fare"><strong>Estimated Taxi FARE:</strong>' + ' £' + cost.toFixed(2) + '</span>'; document.getElementById('miles').innerHTML = '<strong>Distance: </strong>' + miles + ' Miles'; }); } function showLocation() // start of possible values for address not recognized on google search // values for address1 { if (document.forms[0].address1.value == "heathrow" || document.forms[0].address1.value == "Heathrow" || document.forms[0].address1.value == "heathrow airport" || document.forms[0].address1.value == "Heathrow Airport" || document.forms[0].address1.value == "London Heathrow" || document.forms[0].address1.value =="london heathrow" ) { (document.forms[0].address1.value = "Heathrow Airport"); } if (document.forms[0].address2.value == "heathrow" || document.forms[0].address2.value == "Heathrow" || document.forms[0].address2.value == "heathrow airport" || document.forms[0].address2.value == "Heathrow Airport" || document.forms[0].address2.value == "London Heathrow" || document.forms[0].address2.value =="london heathrow" ) { (document.forms[0].address2.value = "Heathrow Airport"); } geocoder.getLocations(document.forms[0].address1.value + document.forms[0].uk.value || document.forms[0].start.value + document.forms[0].uk.value, function (response) { if (!response || response.Status.code != 200) { alert("Sorry, we were unable to find the first address"); } else { location1 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address}; geocoder.getLocations(document.forms[0].address2.value + document.forms[0].uk.value, function (response) { if (!response || response.Status.code != 200) { alert("Sorry, we were unable to find the second address"); } else { location2 = {lat: response.Placemark[0].Point.coordinates[1], lon: response.Placemark[0].Point.coordinates[0], address: response.Placemark[0].address}; gDir.load('from: ' + location1.address + ' to: ' + location2.address); } }); } }); } </script> <style> #quote { font-family: Georgia, "Times New Roman", Times, serif; } </style> </head> <body style="background-color: rgb(255, 255, 255);" onUnload="GUnload()" onLoad="initialize()"> <div id="sidebar"> <!--MAPS--> <div id="calc_top"></div> <div id="calc_body"> <div id="calc_inside"> <span style="font-size: 16px; font-weight: bold;">Get A Quote Now</span> <p class="disclaimer">Fares can be calculated using either Area, Exact Address or Postcode, when entering address please include both road name and area i.e. <em>Harrogate Road, Ripon</em>.

  • Inserting an image into sqlserver gives an "operand type clash"

    - by Termedi
    I'm trying to save an image in a sql server 2000 database. The data type of the column is image. Here is the code: Image Upload: <?php include('config.php'); if(is_uploaded_file($_FILES['userfile']['tmp_name'])) { $fileName = $_FILES['userfile']['name']; $tmpName = $_FILES['userfile']['tmp_name']; $fileSize = $_FILES['userfile']['size']; $fileType = $_FILES['userfile']['type']; $size = filesize($tmpName); set_magic_quotes_runtime(0);//to desactive the default escape spacials caracters made by PHP in the externes files $img_binaire = base64_encode(fread(fopen(str_replace("'","''",$tmpName), "r"), $size)); $query = "INSERT INTO test_image (image_name, image_content, image_size) ".

  • How to pass binary data between two apps using Content Provider?

    - by Viktor
    I need to pass some binary data between two android apps using Content Provider (sharedUserId is not an option). I would prefer not to pass the data (a savegame stored as a file, small in size < 20k) as a file (ie. overriding openFile()) since this would necessitate some complicated temp-file scheme to cope with concurrency with several content provider accesses and a running game. I would like to read the file into memory under a mutex lock and then pass the binary array in the simplest way possible. How do I do this? It seems creating a file in memory is not a possibility due to the return type of openFile(). query() needs to return a Cursor. Using MatrixCursor is not possible since it applies toString() to all stored objects when reading it. What do I need to do? Implement a custom Cursor? This class has 30 abstract methods. Do I read the file, put it in a SQLite db and return the cursor? The complexity of this seemingly simple task is mindboggling.

  • What issues to consider when rolling your own data-backend for Silverlight / AJAX on non-ASP.NET ser

    - by Edward Tanguay
    I have read-only Silverlight and AJAX apps which read static text and XML files from a PHP/Apache server, which works very nicely with features such as asynchronous loading, lazy-loading only what I need for each page, loading in the background, developed a little query language to get a PHP script to create custom XML files etc. it's pragmatic read-only REST, and all works fast and fine for read-only sites. Now I want to also add the ability to write data from these apps to a database on the same PHP/Apache server. For those of you who have built similar data-access layers, what do I need to consider while building this, especially regarding security so that not just any client can write and alter my database, e.g.: check HTTP_USER_AGENT for security check REMOTE_ADDR for security require a special code for security, perhaps a list of TAN codes (such as banks use for online transactions) each which can only be used once, both the client and server have these I wonder if there is some kind of standard REST query I should lean on for e.g. building SQL-like statements in the URL parameters, e.g. http://www.thedatalayersite.com/query?insertinto=customers&... Any thoughts, notes from experience, ideas, gotchas, especially ideas on tightening down security in this endeavor would be helpful.

  • Replacement for deprecated SQL Server User Defined Type with a bound Rule and Default

    - by Adam Jones
    We have a User Defined Data Type of YesNo which has an which is an alias for char(1). The type has a bound Rule (must be Y or N) and a Default (N). The aim of this is that when any of the development team create a new field of type YesNo the rule and default are automatically bound to the new column. Rules and Defaults have been deprecated and won't be available in the next a future version of SQL Server, is there another way to achieve the same functionality? I should add that I'm aware that I could use CHECK and DEFAULT constraints to replicate the functionality of the bound Rule and Defalut objects, however these would have to be applied at each usage of the type, rather than getting the functionality 'for free' by using a UDT which has a bound Rule and Default. The post relates to a database that backs an existing application, rather than a new development, so I'm aware that our use of UDT's is less than optimal. I suspect the answer to the question is 'No', however normally when features are deprecated there's usually an alternative syntax that can be used as a drop in replacement so I wanted to pose the question in-case someone knew of an alternative.

  • Delphi Unicode String Type Stored Directly at its Address (or "Unicode ShortString")

    - by Andreas Rejbrand
    I want a string type that is Unicode and that stores the string directly at the adress of the variable, as is the case of the (Ansi-only) ShortString type. I mean, if I declare a S: ShortString and let S := 'My String', then, at @S, I will find the length of the string (as one byte, so the string cannot contain more than 255 characters) followed by the ANSI-encoded string itself. What I would like is a Unicode variant of this. That is, I want a string type such that, at @S, I will find a unsigned 32-bit integer (or a single byte would be enough, actually) containing the length of the string in bytes (or in characters, which is half the number of bytes) followed by the Unicode representation of the string. I have tried WideString, UnicodeString, and RawByteString, but they all appear only to store an adress at @S, and the actual string somewhere else (I guess this has do do with reference counting and such). Update: The most important reason for this is probably that it would be very problematic if sizeof(string) were variable. I suspect that there is no built-in type to use, and that I have to come up with my own way of storing text the way I want (which actually is fun). Am I right? Update I will, among other things, need to use these strings in packed records. I also need manually to read/write these strings to files/the heap. I could live with fixed-size strings, such as <= 128 characters, and I could redesign the problem so it will work with null-terminated strings. But PChar will not work, for sizeof(PChar) = 1 - it's merely an address. The approach I eventually settled for was to use a static array of bytes. I will post my implementation as a solution later today.

  • Strangely structured xml code finding last value of a certain type using java

    - by Damien.Bell
    Thus the structure is something like this: OasisReportMessagePayloadRTOReport_ItemReport_Data Under report data it's broken into categories: >>Zone >>Type >>Value >>Interval What I need to do is: Get the value if the type is equal to 'myType' and the interval value is the LARGEST. So an example of the xml might be (under report_data): OasisReport MessagePayload RTO REPORT_ITEM REPORT_DATA <zone>myZone1</zone> -- This should be the same in all reports since I only get them for 1 zone <type>myType</type> --This can change from line to line <value>12345</value>--This changes every interval <Interval>122</Interval> -- This is essentially how many 5 minute intervals have taken place since the beginning of a day, finding the "max" lets me know it's the newest data. Thereby I want to find stuff of "MyType" for the "max" interval and pull the Value (into a string, or a double, if not I can convert from string. Can someone help me with this task? Thanks! Note: I've used Xpath to handle things like this in the past, but it seems outlandish for this... as it's SO complex (since not all the reports live in the same report_item, and not all the types are the same in each report)

  • Can you have a Dynamic Data Field which consists of a list of fields?

    - by Telos
    This is a purely theoretical question (at least until I start trying to implement it) but here goes. I wrote a web form a long time ago which has a configurable section for getting information. Basically for some customers there are no fields, for other customers there are up to 20 fields. I got it working by dynamically creating the fields at just the right time in the page lifecycle and going through a lot of headaches. 2 years later, I need to make some pretty big updates to this web form and there are some nifty new technologies. I've worked with ASP.NET Dynamic Data just a bit and, well, I half-crazed plan just occurred to me: The Ticket object has a one-to-many relationship to ExtendedField, we'll call that relationship Fields for brevity. Using that, the idea would be to create a FieldTemplate that dynamically generated the list of fields and displayed it. The big questions here would probably be: 1) Can a single field template resolve to multiple web controls without breaking things? 2) Can dynamic data handle updating/inserting multiple rows in such a fashion? 3) There was a third question I had a few minutes ago, but coworkers interrupted me and I forgot. So now the third question is: what is the third question? So basically, does this sound like it could work or am I missing a better/more obvious solution?

  • Java map with values limited by key's type parameter

    - by Ashley Mercer
    Is there a way in Java to have a map where the type parameter of a value is tied to the type parameter of a key? What I want to write is something like the following: public class Foo { // This declaration won't compile - what should it be? private static Map<Class<T>, T> defaultValues; // These two methods are just fine public static <T> void setDefaultValue(Class<T> clazz, T value) { defaultValues.put(clazz, value); } public static <T> T getDefaultValue(Class<T> clazz) { return defaultValues.get(clazz); } } That is, I can store any default value against a Class object, provided the value's type matches that of the Class object. I don't see why this shouldn't be allowed since I can ensure when setting/getting values that the types are correct. EDIT: Thanks to cletus for his answer. I don't actually need the type parameters on the map itself since I can ensure consistency in the methods which get/set values, even if it means using some slightly ugly casts.

  • Java enums in generic type

    - by Marcin Cylke
    Hi, I'd like to create a generic enum-based mapper for IBatis. I'm doing this with the below code. This does have compile time errors, which I don't know how to fix. Maybe my solution is just plain wrong (keep in mind the use of IBatis), in such case please suggest something better. Any help appreciated. What I want to achieve is to define subsequent mappers as: public class XEnumTypeHandler extends CommonEnumTypeHandler<X> { } The current code: public class CommonEnumTypeHandler<T extends Enum> implements TypeHandlerCallback { public void setParameter(ParameterSetter ps, Object o) throws SQLException { if (o.getClass().isAssignableFrom(**T**)) { ps.setString(((**T**) o).value().toUpperCase()); } else throw new SQLException("Excpected ParameterType object than: " + o); } public Object getResult(ResultGetter rs) throws SQLException { Object o = valueOf(rs.getString()); if (o == null) throw new SQLException("Unknown parameter type: " + rs.getString()); return o; } public Object valueOf(String s) { for (T pt : T.**values()**) { if (pt.**value()**.equalsIgnoreCase(s)) return pt; } return null; } } I've added error markings to the above code, the error messages are in order: T cannot be resolved The method value() is undefined for the type T The method values() is undefined for the type T The method values() is undefined for the type T

  • How do I populate a MEF plugin with data that is not hard coded into the assembly?

    - by hjoelr
    I am working on a program that will communicate with various pieces of hardware. Because of the varied nature of the items it communicates and controls, I need to have a different "driver" for each different piece of hardware. This made me think that MEF would be a great way to make those drivers as plugins that can be added even after the product has been released. I've looked at a lot of examples of how to use MEF, but the question that I haven't been able to find an answer to is how to populate a MEF plugin with external data (eg. from a database). All the examples I can find have the "data" hard-coded into the assembly, like the following example: [Export( typeof( IRule ) )] public class RuleInstance : IRule { public void DoIt() {} public string Name { get { return "Rule Instance 3"; } } public string Version { get { return "1.1.0.0"; } } public string Description { get { return "Some Rule Instance"; } } } What if I want Name, Version and Description to come from a database? How would I tell MEF where to get that information? I may be missing something very obvious, but I don't know what it is. Thanks! Joel

  • Why is Core Data not persisting these changes to disk?

    - by scott
    I added a new entity to my model and it loads fine but no changes made in memory get persisted to disk. My values set on the car object work fine in memory but aren't getting persisted to disk on hitting the home button (in simulator). I am using almost exactly the same code on another entity in my application and its values persist to disk fine (core data - sqlite3); Does anyone have a clue what I'm overlooking here? Car is the managed object, cars in an NSMutableArray of car objects and Car is the entity and Visible is the attribute on the entity which I am trying to set. Thanks for you assistance.

  • Best way to determine variable type and treat each one differently in F#

    - by James Black
    I have a function that will create a select where clause, but right now everything has to be a string. I would like to look at the variable passed in and determine what type it is and then treat it properly. For example, numeric values don't have single quotes around them, option type will either be null or have some value and boolean will actually be zero or one. member self.BuildSelectWhereQuery (oldUser:'a) = let properties = List.zip oldUser.ToSqlValuesList sqlColumnList let init = false, new StringBuilder() let anyChange, (formatted:StringBuilder) = properties |> Seq.fold (fun (anyChange, sb) (oldVal, name) -> match(anyChange) with | true -> true, sb.AppendFormat(" AND {0} = '{1}'", name, oldVal) | _ -> true, sb.AppendFormat("{0} = '{1}'", name, oldVal) ) init formatted.ToString() Here is one entity: type CityType() = inherit BaseType() let mutable name = "" let mutable stateId = 0 member this.Name with get() = name and set restnameval=name <- restnameval member this.StateId with get() = stateId and set stateidval=stateId <- stateidval override this.ToSqlValuesList = [this.Name; this.StateId.ToString()] So, if name was some other value besides a string, or stateId can be optional, then I have two changes to make: How do I modify ToSqlValuesList to have the variable so I can tell the variable type? How do I change my select function to handle this? I am thinking that I need a new function does the processing, but what is the best FP way to do this, rather than using something like typeof?

  • How do I use Core Data with the Cocoa Text Input system?

    - by the Joel
    Hobbyist Cocoa programmer here. Have been looking around all the usual places, but this seems relatively under-explained: I am writing something a little out of the ordinary. It is much simpler than, but similar to, a desktop publishing app. I want editable text boxes on a canvas, arbitrarily placed. This is document-based and I’d really like to use Core Data. Now, The cocoa text-handling system seems to deal with a four-class structure: NSTextStorage, NSLayoutManager, NSTextContainer and finally NSTextView. I have looked into these and know how to use them, sort of. Have been making some prototypes and it works for simple apps. The problem arrives when I get into persistency. I don't know how to, by way of Cocoa Bindings or something else, store the contents of NSTextStorage (= the actual text) in my managed object context. I have considered overriding methods pairs like -words, -setWords: in these objects. This would let me link the words to a String, which I know how to store in Core Data. However, I’d have to override any method that affects the text - and that seems a little much. Thankful for any insights.

  • Update graph in real time from server

    - by user1869421
    I'm trying to update a graph with received data, so that the height of the bars increase as more data is received from the server via a websocket. But my code doesn't render a graph in the browser and plot the data points. I cannot see anything wrong with the code. I really need some help here please. ws = new WebSocket("ws://localhost:8888/dh"); var useData = [] //var chart; var chart = d3.select("body") .append("svg:svg") .attr("class", "chart") .attr("width", 420) .attr("height", 200); ws.onmessage = function(evt) { var distances = JSON.parse(evt.data); data = distances.miles; console.log(data); if(useData.length <= 10){ useData.push(data) } else { var draw = function(data){ // Set the width relative to max data value var x = d3.scale.linear() .domain([0, d3.max(useData)]) .range([0, 420]); var y = d3.scale.ordinal() .domain(useData) .rangeBands([0, 120]); var rect = chart.selectAll("rect") .data(useData) // enter rect rect.enter().append("svg:rect") .attr("y", y) .attr("width", x) .attr("height", y.rangeBand()); // update rect rect .attr("y", y) .attr("width", x) .attr("height", y.rangeBand()); var text = chart.selectAll("text") .data(useData) // enter text text.enter().append("svg:text") .attr("x", x) .attr("y", function (d) { return y(d) + y.rangeBand() / 2; }) .attr("dx", -3) // padding-right .attr("dy", ".35em") // vertical-align: middle .attr("text-anchor", "end") // text-align: right .text(String); // update text text .data(useData) .attr("x", x) .text(String); } useData.length = 0; } } Thanks

  • Call a dynamically generated method on a ILGenerator on the same type

    - by Thiado de Arruda
    Normally, when I want to call a dynamic method in another ILGenerator object that is writing a method on the same type I do the following : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, methodBuilder); //this methodbuilder is also defined on this dynamic type. However, I faced the following problem: I cant have a reference to the methodbuilder of the method I want to call, because it is generated by another framework(I only get a reference to the current TypeBuilder). This method is defined as protected virtual(and overriden on the methodbuilder I cant get a reference to) in the base class of the current dynamic type and I can get a reference to it by doing this : generator.Emit(OpCodes.Ldarg_0); // reference to the current object generator.Emit(OpCodes.Ldstr, "someArgument"); generator.Emit(OpCodes.Call, baseType.GetMethod("SomeMethodDefinedInBaseClassThatWasOverridenInThisDynamicType")); The problem is that this calls the method on the base type and not the overriden method. Is there any way I can get a reference to a methodbuilder only having a reference to the typebuilder that defined it? Or is there a way to call a method using ILGenerator without having to pass the 'MethodInfo' object to it?

  • Most elegant way to break CSV columns into separate data structures using Python?

    - by Nick L
    I'm trying to pick up Python. As part of the learning process I'm porting a project I wrote in Java to Python. I'm at a section now where I have a list of CSV headers of the form: headers = [a, b, c, d, e, .....] and separate lists of groups that these headers should be broken up into, e.g.: headers_for_list_a = [b, c, e, ...] headers_for_list_b = [a, d, k, ...] . . . I want to take the CSV data and turn it into dict's based on these groups, e.g.: list_a = [ {b:val_1b, c:val_1c, e:val_1e, ... }, {b:val_2b, c:val_2c, e:val_2e, ... }, {b:val_3b, c:val_3c, e:val_3e, ... }, . . . ] where for example, val_1b is the first row of the 'b' column, val_3c is the third row of the 'c' column, etc. My first "Java instinct" is to do something like: for row in data: for col_num, val in enumerate(row): col_name = headers[col_num] if col_name in group_a: dict_a[col_name] = val elif headers[col_cum] in group_b: dict_b[col_name] = val ... list_a.append(dict_a) list_b.append(dict_b) ... However, this method seems inefficient/unwieldy and doesn't posses the elegance that Python programmers are constantly talking about. Is there a more "Zen-like" way I should try- keeping with the philosophy of Python?

  • Avoid an "out of memory error" in Java(eclipse), when using large data structure?

    - by gnomed
    OK, so I am writing a program that unfortunately needs to use a huge data structure to complete its work, but it is failing with a "out of memory error" during its initialization. While I understand entirely what that means and why it is a problem, I am having trouble overcoming it, since my program needs to use this large structure and I don't know any other way to store it. The program first indexes a large corpus of text files that I provide. This works fine. Then it uses this index to initialize a large 2D array. This array will have nXn entries, where "n" is the number of unique words in the corpus of text. For the relatively small chunk I am testing it on(about 60 files) it needs to make approximately 30,000x30,000 entries. this will probably be bigger once I run it on my full intended corpus too. It consistently fails every time, after it indexes, while it is initializing the data structure(to be worked on later). Things I have done include: revamp my code to use a primitive "int[]" instead of a "TreeMap" eliminate redundant structures, etc... Also, I have run eclipse with "eclipse -vmargs -Xmx2g" to max out my allocated memory I am fairly confident this is not going to be a simple line of code solution, but is most likely going to require a very new approach. I am looking for what that approach is, any ideas? Thanks, B.

  • Dynamically cast a control type in runtime

    - by JayT
    Hello, I have an application whereby I dynamically create controls on a form from a database. This works well, but my problem is the following: private Type activeControlType; private void addControl(ContainerControl inputControl, string ControlName, string Namespace, string ControlDisplayText, DataRow drow, string cntrlName) { Assembly assem; Type myType = Type.GetType(ControlName + ", " + Namespace); assem = Assembly.GetAssembly(myType); Type controlType = assem.GetType(ControlName); object obj = Activator.CreateInstance(controlType); Control tb = (Control)obj; tb.Click += new EventHandler(Cntrl_Click); inputControl.Controls.Add(tb); activeControlType = controlType; } private void Cntrl_Click(object sender, EventArgs e) { string test = ((activeControlType)sender).Text; //Problem ??? } How do I dynamically cast the sender object to a class that I can reference the property fields of it. I have googled, and found myself trying everything I have come across..... Now I am extremely confused... and in need of some help Thnx JT

  • Inheritance and type parameters of Traversable

    - by Jesper
    I'm studying the source code of the Scala 2.8 collection classes. I have questions about the hierarchy of scala.collection.Traversable. Look at the following declarations: package scala.collection trait Traversable[+A] extends TraversableLike[A, Traversable[A]] with GenericTraversableTemplate[A, Traversable] trait TraversableLike[+A, +Repr] extends HasNewBuilder[A, Repr] with TraversableOnce[A] package scala.collection.generic trait HasNewBuilder[+A, +Repr] trait GenericTraversableTemplate[+A, +CC[X] <: Traversable[X]] extends HasNewBuilder[A, CC[A] @uncheckedVariance] Question: Why does Traversable extend GenericTraversableTemplate with type parameters [A, Traversable] - why not [A, Traversable[A]]? I tried some experimenting with a small program with the same structure and got a strange error message when I tried to change it to Traversable[A]: error: Traversable[A] takes no type parameters, expected: one I guess that the use of the @uncheckedVariance annotation in GenericTraversableTemplate also has to do with this? (That seems like a kind of potentially unsafe hack to force things to work...). Question: When you look at the hierarchy, you see that Traversable inherits HasNewBuilder twice (once via TraversableLike and once via GenericTraversableTemplate), but with slightly different type parameters. How does this work exactly? Why don't the different type parameters cause an error?

  • "javascript:" on browser won't change the type.

    - by raj
    look at this code, <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script> function change() { document.getElementById("myInput").type="text"; } </script> </head> <body onload="setTimeout('change()',2000);"> <input type = "button" id="myInput"> </body> </html> now, my button becomes text box after 2 seconds.. Iam happy! Why not the same happens when i try to do from the browser (i tested in IE6 & Chrome) using javascript:document.getElementById("myInput").type="text" different browsers behave in different way... when i tried javascript:document.getElementById("myInput").value="myNewValue", IE6 changes the value, but chrome doesn't.. Why is this "javascript:" behaving like this ?
