Hi Guys

Please could someone help me with the following. I have a table that i want to itterate through and display all the text inside certain span tags.

The below example is a basic example of what i want to do. Also this works fine in IE, Chrome and Firefox, But Safari returns Undefined.

I have been able to find that the "enumerable.from(c.cells).foreach" is where the problem is.

<body>
<table id="tableone"> <tr id="rowTest"> <td id="test"> <span id="thisname"><span id="1fName">TR 1 TD 1</span></span> </td> <td><span id="thisperson">TR 1 TD 2</span></td> </tr> <tr id=""> <td id="test"> <span id="thisname"><span id="2fName">R 2 TD 1</span></span> </td> <td><span id="thisperson">TR 2 TD 2</span></td> </tr> </table> <script> $.Enumerable.From($('#tableone tr')).Where('$.id != ""').ForEach(function(e){ $.Enumerable.From(e.cells).ForEach(function(a){  alert($(a).find('span[id*=fName]').html()); }); }); </script> </body>

GroupBy has three arguments.

for example

// keySelector, elementSelector, resultSelector
// group is Enumerable
Enumerable.From(resultArray)
    .GroupBy("$.sucursal", "", function (key, group) { return { sucu: key, group: group } })
    .ForEach(function (x) { alert(x.sucu + ' ' + x.group.Select("$.name").ToString(",")) });

You should use this statement

var queryText = Enumerable.From(jsonArray).Where("$.text == 'g'").ToArray();
var queryId = Enumerable.From(jsonArray).Where("$.user.id == '135'").ToArray();

Hi

I am trying to understand the GroupBy, but the documentation is little

has somebody some example about GroupBy ?

in the example, I can see:
.GroupBy("$.Date", "$.Id", .....

why two parameters ? if only need group by date, which is the $.Id functionality ?

Hi

I need use GroupBy, I am processing crm data

function GetArrayFromFetchResults(fetchResults) {

    var entityResults = new Array();

    var entityElems = fetchResults.getElementsByTagName("a:Entity");

    for (var i = 0; i < entityElems.length; i++) {

        entityResults[i] = new Object();
        
        entityResults[i].id = GetFieldValue(entityElems[i], "accountid");
        entityResults[i].name = GetFieldValue(entityElems[i], "name");

        entityResults[i].latitude = GetFieldValue(entityElems[i], "address1_latitude");
        entityResults[i].longitude = GetFieldValue(entityElems[i], "address1_longitude");

        entityResults[i].zona = GetFieldValue(entityElems[i], "new_zona");
        entityResults[i].sucursal = GetFieldValue(entityElems[i], "new_sucursalprincipal");
        entityResults[i].vendedor = GetFieldValue(entityElems[i], "new_vendedorasigandoid");

    }
   
    return entityResults;
}

I need group result by "sucursal", end then use the ForEach(), but I don´t find the correct parameters

var resultArray = GetArrayFromFetchResults(resultCRM);

Enumerable.From(resultArray)
                                .GroupBy("$.sucursal",
                                    function(key, group) { return { sucu: key, grupo: group} })
                                .ForEach(alert($.sucu + ' ' + $.grupo));

greetings

Is your query syntax right?
It looks need "into" keyword.

// query syntax
var table = from c in ctx.Users
            join p in ctx.Structure on c.StructureID equals p.StructureID.ToString()
            select c into c
            where c.UserID < 276234
            select c;

// method syntax
var table2 = ctx.Users.Join(ctx.Structure, c => c.StructureID, p => p.StructureID.ToString(), (c, p) => c)
    .Where(c => c.UserID < 276234);

// linq.js
var table = ctx.Users.Join(ctx.Structure, "$.StructureID", "$.StructureID.toString()")
    .Where("$.UserID < 276234");

I what use Join in Linq.js, Is Different with C#?

var table = from c in ctx.Users
                 join p in ctx.Structure
                 on c.StructureID equals p.StructureID.ToString()
                 where c.UserID < 276234
                 select c;

What can I do using linq.js achieve the above functions,it's two tables join by foreign key(ID)

neuecc — Mon, 29 Apr 2013 14:51:11 GMT

result of GroupBy have to keep immutable.
source property intend to private field.
linq.js ver.3 changed Key() -> key() and source -> getSource()
(and getSource is private but practically public)

New Post: Group By

MgSam — Thu, 25 Apr 2013 16:05:15 GMT

I find the Linq.js GroupBy a little confusing. What is the reason for the Key property on the result of a GroupBy being a function that returns the key, rather than the key itself?

Also, why does the GroupBy result have a source property (notice the difference in casing) rather than something like Values?

Thanks.

New Post: How to query this XML.

raptor_ttk — Mon, 15 Apr 2013 16:44:46 GMT

Hello,

I was looking the documentation about linq.js and i saw you're implementing a way to query xml. I want to know if currently is there a way to query this XML.

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body>
    <GetUserResponse xmlns="http://tempuri.org/">
      <GetUserResult xmlns:a="http://schemas.data contract.org/2004/07/Service" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <a:id>1</a:id>
        <a:nombre>George</a:nombre>
        <a:direccion>Address</a:direccion>
        <a:email>Email</a:email>
      </GetUserResult>
     </GetUserResponse>
  </s:Body>
</s:Envelope>

Note: I am getting this XML inside a string variable.

As you can see, the SOAP XML returns 4 properties: <a:id> <a:nombre> <a:direccion> <a:email>, I want to get the values inside each property.

Thank you.

New Post: Linq.js project dead?

andhaug — Fri, 12 Apr 2013 12:28:55 GMT

I've been happily using Linq.js v2 in a previous project. We are now in the process of starting a new project, and I'm considering using it again. I'm looking forward to the v3 which seem to align itself more with javascript naming conventions. What worries me is that there seem to be very little activity on this project. Last checkin on the v3 branch was Oct 09, 2012.

Is it still alive and being developed, and can we expect v3 released any time soon?

rrsavadikar — Fri, 05 Apr 2013 12:26:03 GMT

Consider the same json array..

var jsonArray = [

{ "user": { "id": 100, "screen_name": "d_linq" }, "text": "to objects" },
{ "user": { "id": 130, "screen_name": "c_bill" }, "text": "g" },
{ "user": { "id": 155, "screen_name": "b_mskk" }, "text": "kabushiki kaisha" },
{ "user": { "id": 301, "screen_name": "a_xbox" }, "text": "halo reach" }

]

var queryResult = Enumerable.From(jsonArray).Where("$.user.text == 'g'").ToArray();

if i use above statement on 'text' field, it works perfectly fine.

var queryResult = Enumerable.From(jsonArray).Where("$.user.id == 100").ToArray();

but when i try to use above statement on 'id' field, it does not filter the result accordingly, instead it returns complete json array.

I also tried converting integers from json array to strings as shown below bu it did not help either.

var jsonArray = [

            { "user": { "id": "100", "screen_name": "d_linq" }, "text": "to objects" },
            { "user": { "id": "100", "screen_name": "c_bill" }, "text": "g" },
            { "user": { "id": "155", "screen_name": "b_mskk" }, "text": "kabushiki kaisha" },
            { "user": { "id": "301", "screen_name": "a_xbox" }, "text": "halo reach" }
        ]

I tried using '=' , '==' and putting single quotes, etc etc in lambda equations but no luck.

It works perfectly fine for strings with alphabets and not for numbers.

Please help me.

New Post: Starting linq.js ver.3.0.0(currently beta)

booolean — Fri, 08 Mar 2013 08:12:59 GMT

Thanks for your AMAZING JOB create this library. I agree to change function names to lowercase. But I'm not gonna using 3.0 in my project cause lot of codes are using UpperCase. So will you consider to make a back compability adapter library like jQuery-Migrate.js? I thinks those are just a little alias-name work.

What do you think?
