how to generate array based on page wise

CHECKBOXPAGING.html

We will make an associative array for this where in MyArray is key value pair:-

var MyArray = {
1 : ["1","3","4","5"],
2 : ["2","6","7"],
3 : ["8","9","11"],
getValue : function(key) {
console.log(MyArray[key]);
}
};

MyArray.getValue(2);

Select allOpen in new window

If you need to declare/define arrays in a recursive way, I suggest to use "eval" function associated with cycles. For example, if "myArray-k" is one of the N the arrays you want to define and you also have a sort of rule to set its contents (i.e. 4 sequential integers each), you can do like this:
for (k = 1; k < N+1; k++) {
      eval("var myArray"+k+"=new Array();");
      for (j = 1; j < 5; j++) {
            eval("myArray["+k+"]="+(k*4-4+j)+";");
      }
}
You can also declare one only array[k][j] if the length of its rows is constant.

BuggyCoder,

.when i check checkbox i want array in below format.

how to create array in the below format?

var MyArray = {
1 : ["1","3","4","5"],
2 : ["2","6","7"],
3 : ["8","9","11"],
};

Declare this javascript object as global object in you js file:-

var MyArray = {
1 : ["1","3","4","5"],
2 : ["2","6","7"],
3 : ["8","9","11"],
getValue : function(key) {
return MyArray[key];
}
};

Select allOpen in new window

Next on the click of check box call its getValue with your key(1/2/3) method as:-

MyArray.getValue(1);

Select allOpen in new window

This will return an array from the type....

buggycoder,

you didnt understand my question.first of all i need to prepare like this when user checked checkbox.how to push the values in MyArray .do i need to use MyArray .push method.how will you insert key and value pairs.

> how will you insert key and value pairs.
// assuming MyArray hash already exists:

MyArray["42"] = ["43","44"];

> how to push the values in MyArray
// as MyArray is a hash, you can "push" values as described above, but you cannot use JavaScripts Array.push(); however, you probably meant:

MyArray["42"].push("45");

If you use a normal array, you can push an array.
MyArray.push([45,46])

Nope
MyMultiArray[0].push("4");
MyMultiArray[0].push("8");

If you push them in the same line, the array becomes:
["1", "2", "3", "4", "8"], ["5", "6", "7", , ]]
which is to say that you get 2 undefined values.
Try it yourself by customizing yor code and calling a generic fruits[x][y] element in this demo:

Enough said

sorry for the late reply.actually am doing checkbox pagination.for each page 5 records will be displayed.so i want to know on each page howmany values has been checked.

see the attached example.
how to construct JSON in this format;

[{"1":"1,2,3"},{"2":"6,7,8"}]
checkbox.html

if JSON structure is like this;

var checkboxvalues=
[
    {
        "pageno": 1,
        "values": "1,2,3"
       
    },
    {
        "pageno": 2,
        "values": "6,7,8"
    }
]


how to retreive page:2 related values??

checkboxvalues[1].values;

javascript arrays are 0 based

Can you answer my previous Q?

how to construct JSON in this format;

[{"1":"1,2,3"},{"2":"6,7,8"}]

If you expect gaps in the pages, use object array

Pages={
  page1:[1,0,0,1,1],
  page5:[1,0,0,0,1]
}

If not, use simple array of arrays perhaps there is no need for JSON
Pages=[[1,0,0,1,1],[1,0,0,0,1]]

The correct syntax in a single explicit declaration should be:
var checkboxvalues = [ { "pageno": "1", "values": ["value1", "value2", "value3"] }, { "pageno": "2", "values": ["value4", "value5", "value6"] } ]
If you want a recursive/iterational declaration with "eval" function, you'll need single quotes, pluses and other separators and indexes.

"eval"  is VERY SELDOM necessary and should be avoided as much as possible

This is syntactically correct too
var checkBoxArrayPerPage={
  page1:[1,0,0,1,1],
  page5:[1,0,0,0,1]
}

how to construct JSON array in this format .when i checkbox values in page1 then how to append values in page 1 and simulataneously if user uncheck then how can you remove the values from page1.


var checkboxvalues = [ { "pageno": "1", "values": ["value1", "value2", "value3"] }, { "pageno": "2", "values": ["value4", "value5", "value6"] } ]
