• JQuery - remove the chars not matching regEx

  - by JQueryBeginner

  Hi All, I am trying to use jquery for validating forms. This is the pattern that is allowed in a text box for a user. var pattern = /^[a-zA-Z0-9!#$&%*+,-./: ;=?@_]/g; If the user types anything else other than this then that has to be replaced with a "". $(document).ready(function() { $('#iBox').blur(function() { var jVal = $('#iBox').val(); if(jVal.match(pattern)) { alert("Valid"); } else { alert("New "+jVal.replace(!(pattern),"")); } }); }); }); But the replace function does not work this way.

• jQuery access each matched element from '.find' by an index

  - by GHarping

  Using jQuery's .find() method to return a set of elements, I am trying to access items in the returned set by their order in that set. For example, a table with two rows and in each row a select box and two text input fields, accessed with the following: $('table#tbl').find('tr.row').each(function(i) { }); To get the first element I would have thought I could use $('table#tbl').find('tr.row').each(function(i) { alert( $(this).find(':input').get(1).val() ); }); And variations of the above, but apparently this doesn't work. Could anyone suggest the correct method to access item x of n elements returned?

  Hey Guys, I have the following html: HTML markup <ul id="test"> <li><a href="http://www.yahoo.com">yahoo</a></li> <li><a href="http://www.google.com">Google</a></li> </ul> And some JS code: JQuery/JavaScript Code $('ul#test').each(function() { var select=$(document.createElement('select')).insertBefore($(this).hide()); $('>li a', this).each(function() { option=$(document.createElement('option')).appendTo(select).val(this.href).html($(this).html()); }); }); This code produces a select dropdown menu, exactly what I want, but my question is how do I go to the url on select? So if I click yahoo, it brings me to yahoo.com? Thanks for your help!

• Remove duplicates in entries, scala way

  - by andersbohn

  I have a list of entries stating a production value in a given interval. Entries stating the exact same value at a later time adds no information and can safely be left out. case class Entry(minute:Int, production:Double) val entries = List(Entry(0, 100.0), Entry(5, 100.0), Entry(10, 100.0), Entry(20, 120.0), Entry(30, 100.0), Entry(180, 0.0)) Experimenting with the scala 2.8 collection functions, so far I have this working implementation: entries.foldRight(List[Entry]()) { (entry, list) => list match { case head :: tail if (entry.production == head.production) => entry :: tail case head :: tail => entry :: list case List() => entry :: List() } } res0: List[Entry] = List(Entry(0,100.0), Entry(20,120.0), Entry(30,100.0), Entry(180,0.0)) Any comments? Am I missing out on some scala magic?

• Collection type generated by for with yield

  - by Jesper

  When I evaluate a for in Scala, I get an immutable IndexedSeq (a collection with array-like performance characteristics, such as efficient random access): scala> val s = for (i <- 0 to 9) yield math.random + i s: scala.collection.immutable.IndexedSeq[Double] = Vector(0.6127056766832756, 1.7137598183155291, ... Does a for with a yield always return an IndexedSeq, or can it also return some other type of collection class (a LinearSeq, for example)? If it can also return something else, then what determines the return type, and how can I influence it? I'm using Scala 2.8.0.RC3.

• Why does the Scala compiler disallow overloaded methods with default arguments?

  - by soc

  While there might be valid cases where such method overloadings could become ambiguous, why does the compiler disallow code which is neither ambiguous at compile time nor at run time? Example: // This fails: def foo(a: String)(b: Int = 42) = a + b def foo(a: Int) (b: Int = 42) = a + b // This fails, too. Even if there is no position in the argument list, // where the types are the same. def foo(a: Int) (b: Int = 42) = a + b def foo(a: String)(b: String = "Foo") = a + b // This is OK: def foo(a: String)(b: Int) = a + b def foo(a: Int) (b: Int = 42) = a + b // Even this is OK. def foo(a: Int)(b: Int) = a + b def foo(a: Int)(b: String = "Foo") = a + b val bar = foo(42)_ // This complains obviously ... Are there any reasons why these restrictions can't be loosened a bit? Especially when converting heavily overloaded Java code to Scala default arguments are a very important and it isn't nice to find out after replacing plenty of Java methods by one Scala methods that the spec/compiler imposes arbitrary restrictions.

  - by Cesar Lopez

  I have the following function: var emptyFields = false; function checkNotEmpty(tblName, columns, className){ emptyFields = false; $("."+className+"").each(function() { if($.trim($(this).val()) === "" &amp;&amp; $(this).is(":visible")){ emptyFields = true; return false; // break out of the each-loop } }); if (emptyFields) { alert("Please fill in current row before adding a new one."); } else { AddRow_OnButtonClick(tblName,columns); } } Its checking that all elements in the table are not empty before adding a new row, and I only need to check that the last row of the table has at least an element which its not empty and not the whole table. Any help would be apreciated. Thanks

• Two methods with different signatures, jquery is not calling correct method

  - by Lee

  There are two methods GetUserAssignedSystems() and GetUserAssignedSystems(string Id) These methods act very differently from each other. The problem is, when I want to call GetUserAssignedSystems(string Id), the parameter-less method is called. Here are the methods: [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems(string cacId) { return Data.UserManager.GetUserAssingedSystems(cacId); } [WebMethod] [ScriptMethod] public IEnumerable GetUserAssignedSystems() { //do something else } Here is the jquery making the call: CallMfttService("ServiceLayer/UserManager.asmx/GetUserAssignedSystems", "{'cacId':'" + $('#EditUserCacId').val() + "'}", function(result) { for (var userSystem in result.d) { $('input[UserSystemID=' + result.d[userSystem] + ']').attr('checked', 'true'); } }); Any ideas why this method is being ignored?

• Scala loop returns as Unit and compiler points to "for" syntax?

  - by DeLongey

  Seems like Unit is the theme of my troubles today. I'm porting a JSON deserializer that uses Gson and when it comes to this for loop: def deserialize(json:JsonElement, typeOfT:Type, context:JsonDeserializationContext) = { var eventData = new EventData(null, null) var jsonObject = json.getAsJsonObject for(entry <- jsonObject.entrySet()) { var key = entry.getKey() var element = entry.getValue() element if("previous_attributes".equals(key)) { var previousAttributes = new scala.collection.mutable.HashMap[String, Object]() populateMapFromJSONObject(previousAttributes, element.getAsJsonObject()) eventData.setPreviousAttributes(previousAttributes) eventData } else if ("object".equals(key)) { val `type` = element.getAsJsonObject().get("object").getAsString() var cl = objectMap.get(`type`).asInstanceOf[StripeObject] var `object` = abstractObject.retrieve(cl, key) eventData.setObject(`object`) eventData } } } The compiler spits out the error type mismatch; found : Unit required: com.stripe.EventData and it points to this line here: for(entry <- jsonObject.entrySet()) Questions Confirm that it is indeed the Gson method entrySet() appearing as unit? If not, what part of the code is creating the issue? I've set return types/values for eventData class methods Is there a workaround for the Gson Unit issue? Thanks!

• JSON from $.each()

  - by Matthew

  I'm trying to get a list of the values of all checked checkboxes that looks like this: foo = { 'colors': ['blue', 'red', 'green'], 'flavors': ['vanilla', 'chocolate'] }; This is the approach I'm taking so far, but JS is saying that 'colors' doesn't exist when I try to push a new value to it. I'm assuming this is a scope issue but I don't know how to fix it. var foo = {}; foo.colors = []; $(".colors:checked").each(function(){ foo.colors.push($(this).val()); });

• insert DropDownList and TextField in Gridview

  - by userk

  HI,I need to create a GridView which DataSource is an object. Depending on the object I may need some columns with DropDownLists or TextFields (but not all rows) As I don't know the number or columns, they have to be dynamic. I found this solution: TemplateField t = new TemplateField(); t.HeaderTemplate = new GridViewTemplate("header", "title"); t.ItemTemplate = new GridViewTemplate("combobox", "val"); GridView1.Columns.Add(t); GridView1.DataSource = ds; GridView1.DataBind(); Where GridViewTemplate extends ITemplate. This didn't work for me, it fills all rows of a column and I had no way to control witch DropDownList and TextFields need to be created (object info). All the DropDownLists need to have an ID also only known by the object. There are some way I can do this?

• Why is '\x' invalid in Python?

  - by Paul McGuire

  I was experimenting with '\' characters, using '\a\b\c...' just to enumerate for myself which characters Python interprets as control characters, and to what. Here's what I found: \a - BELL \b - BACKSPACE \f - FORMFEED \n - LINEFEED \r - RETURN \t - TAB \v - VERTICAL TAB Most of the other characters I tried, '\g', '\s', etc. just evaluate to the 2-character string of a backslash and the given character. I understand this is intentional, and makes sense to me. But '\x' is a problem. When my script reaches this source line: val = "\x" I get: ValueError: invalid \x escape What is so special about '\x'? Why is it treated differently from the other non-escaped characters?

• jquery ui autcomplete does not disapper with no result

  - by mike

  Hi, I'm using jquery ui autocomplete with the following code: $('#company').autocomplete({ source: function(request, response) { var company_name = $('#company').val(); $.ajax({ type: 'post', url: 'http://new.admin.localhost/client/helper/lookup_company_name', cache: false, data: { company : company_name }, dataType: 'json', success: function(data) { //alert(data); response($.map(data.companies, function(item) { return { label: item.company, value: item.company } })) } }) }, minLength: 2, }); This works as expected... The problem is, if the first few chars match something and then you enter a char that should "break" any match, it just keeps the drop down in place with the results for the last matched char... make sense? Would this be something I needed to change in the script that returns the data or something in the jquery? thanks!

• Dynamically creating/inserting into an associative array in PHP

  - by emil.mp

  I'm trying to build an associative array in PHP dynamically, and not quite getting my strategy right. Basically, I want to insert a value at a certain depth in the array structure, for instance: $array['first']['second']['third'] = $val; Now, the thing is, I'm not sure if that depth is available, and if it isn't, I want to create the keys (and arrays) for each level, and finally insert the value at the correct level. Since I'm doing this quite a lot in my code, I grew tired of doing a whole bunch of "array_key_exists", so I wanted to do a function that builds the array for me, given a list of the level keys. Any help on a good strategy for this is appreciated. I'm sure there is a pretty simple way, I'm just not getting it...

• check for a span class content and then update the quantity using jquery?

  - by PD24

  I have code code here: //Check current if (parseInt($("#Quantity").val()) < 25) { // If it is less than 25 then set it to 25 $("#Quantity").attr("value", "25"); } It checks if the quantity box has less than 25 and if it is, adds 25 to the box. The problem is on a particular product i need to check IF my pages contains: <span class="ProductNameText">This is product ABC</span> This is a work around because the customer only has 2 products which dont require 25 quantity. Ideally i would want to check if a page contained Kit Option form fields and then add 25 to the box. Any ideas on how to check for a span and then update the quantity. But the quantity shouldnt be forced, so if the user wants 6 items they should be able to add that figure.
