Javascript - How to add objects to column array in kendo ui grid dynamically?

Question

I am trying to generate objects in the columns array as the heading implies, although I haven't found a working method.

alert( "Value 1: " + temporaryArray[1] + " - " + finalArray[1].values ); 
alert( "Value 2: " + temporaryArray[2] + " - " + finalArray[2].values ); 
var myGrid =  $("#grid").kendoGrid( 
{
    columns: 
    [
        {
            title: temporaryArray[0] + " ",
            field: gridArray[0].values + " "
        }
    ],
    dataSource: 
    {
        data:finalArray,
        pageSize:10
    },
    scrollable:false,
    pageable:true 
});

I've tried the following to add the object:

for( var x = 0; x < finalArray.length; x++ )
{
    myGrid[columns] = { temporaryArray[x]:finalArray[x] };
}

And

for( var x = 0; x < finalArray.length; x++ )
{
    myGrid.columns[values]= finalArray[x].values;
}

with no success...

The following looks like an array of objects inside of the object which I want to achieve dynamically:

columns: 
[
    {
        title: temporaryArray[0] + " ",
        field: gridArray[0].values + " "
    },
    {
        title: temporaryArray[1] + " ",
        field: gridArray[1].values + " "
    },
    {
        title: temporaryArray[2] + " ",
        field: gridArray[2].values + " "
    }
],

For example:

for( var x = 0; x < finalArray.length; x++ )
{
    myGrid[columns] = { temporaryArray[x]:finalArray[x] };
}

I want to generate the objects using a for loop to generate an array of objects inside the column array.

What I want to know is, whether this is possible to do dynamically? or just possible at all without hard coding it?

Answer 1

You can do it. Lets have the Titles stored in titleDefs and the field name in fieldDef. Then you should do:

// Title Definitions
var titleDefs = [
    "First Name", "Last Name", "Title"
];
// Field Definition
var fieldDefs = [
    "FirstName", "LastName", "Title"
];
// Lets compute column definition
var columnDefs = [];
for (var i = 0; i < titleDefs.length; i++) {
    columnDefs.push({ title : titleDefs[i], field: fieldDefs[i] });
}
// Now, create the grid using columnDefs as argument
var grid = $("#grid").kendoGrid({
    dataSource: {
        data    : dataArray,
        pageSize: 10
    },
    columns   : columnDefs
}).data("kendoGrid");

NOTE: In this example I've defined a DataSource that is a JavaScript array in memory but you can get the data from a server changing the DataSource definition.

NOTE: In your code, you were adding extra white space to the title definition and that is not correct: column definitions are JavaScript code and not strings so you don't have to format it as you were going to display it.
