chaining

问题 My AJAX calls are built inside of a for loop. They need to be in order (synchronous). How do I chain them with jQuery? var array = ['One', 'Two', 'Three']; var arrayLength = array.length; for (var arrayCounter = 0; arrayCounter < arrayLength; arrayCounter++) { var id = array[arrayCounter]; getData(id); function getData(id) { $.ajax({ url: 'http://example.com/' + id, dataType: 'jsonp', success: function(d) { var response = d; console.log(d); }, error: function() { alert("ERROR"); } }); } } 回答1

问题 Given this following sample code which clones a table row, sets some properties and then appends it to a table: $("#FundTable").append( objButton.parents("tr").clone() .find(".RowTitle").text("Row " + nAddCount).end() .find(".FundManagerSelect").attr("id", "FundManager" + nAddCount) .change(function() { ChangeFundRow(); }).end() .find(".FundNameSelect").attr("id", "FundName" + nAddCount).end() ); Does anyone have any suggestions as to how this might be formatted to be easier on the eye? Is

问题 I have multiple functions the do different animations to different parts of the HTML. I would like to chain or queue these functions so they will run the animations sequentially and not at the same time. I am trying to automate multiple events in sequence to look like a user has been clicking on different buttons or links. I could probably do this using callback functions but then I would have to pull all of the animations from the different functions and regroup in the right pattern. Does

问题 I have a function that takes an ostream reference as an argument, writes some data to the stream, and then returns a reference to that same stream, like so: #include <iostream> std::ostream& print( std::ostream& os ) { os << " How are you?" << std::endl; return os; } int main() { std::cout << "Hello, world!" << print( std::cout ) << std::endl; } The output of this code is: How are you? Hello, world!0x601288 However, if I separate the chaining expressions into two statements, like this int

问题 I am mostly interested in Java, but I think it's a general question. Recently I've been working with Arquillian framework ( ShrinkWrap ) that uses a lot of method chaining. Other example of method chaining are methods in StringBuilder , StringBuffer . There are obvious benefits of using this approach: reduced verbosity is one of them. Now I was wondering, why aren't all methods which have void return parameter implemented as chainable? There must be some obvious and objective drawback in

问题 Quite recently I read about JavaScript call usage in MDC https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/call one linke of the example shown below, I still don't understand. Why are they using inheritance here like this Prod_dept.prototype = new Product(); is this necessary? Because there is a call to the super-constructor in Prod_dept() anyway, like this Product.call is this just out of common behaviour? When is it better to use call for the super-constructor or

问题 Say you have nested collections a , b , and c , which follow the following map: {"collection":"a", "children":[{"collection":"b", "name":"bee", "children"[{"collection":"c","name":"cee"}]}]} And here is a1 , fetched from a MongoDb database with $http : {"title":"title a1", "id":"a1", "bee":[{"id":"b1"},{"id":"b2"}], "other_array":[{"foo":"bar"},{"foo":"baz"}]} Right now, in the bee array, we have only references ( id ). What we want is to keep following the map to update a1 , and replace

问题 In c++ we can easily set up method chaining in a class by designing methods returning *this. Would this be possible in an ATL/COM setting ? Let's say I have a simple ATL class MyOBj. I would like to know if chaining is possible in this context, and if so, what would be the idl signature of the method that would support chaining ? Simple examples would be appreciated ! (In fact, my methods are called from VBA for excel, and I would like to have chaining in that VBA context, as we have chaining

问题 I have an XSLT file so as to transform large amount of data. I would like to add a "split" functionality, either as a chained XSLT or within the current XSLT that can create multiple output files so as to limit the size of the files under a certain threshold. Let's assume that the input XML is as below: <People> <Person> <name>John</name> <date>June12</date> <workTime taskID="1">34</workTime> <workTime taskID="2">12</workTime> </Person> <Person> <name>John</name> <date>June13</date> <workTime

问题 I have a Tuple mock class, whose getString(0) and getString(1) methods are expected to be called n times. Instead of writing something like, when(tuple.getString(0)).thenReturn(logEntries[0]).thenReturn(logEntries[1])...thenReturn(logEntries[n - 1]) manually, I tried the following: OngoingStubbing stubbingGetStringZero = when(tuple.getString(0)).thenReturn(serviceRequestKey); OngoingStubbing stubbingGetStringOne = when(tuple.getString(1)).thenReturn(logEntries[0]); for (int i = 1; i < n; i++)
