Tips for effectively handling numerous events from multiple Slickgrid instances on a single page

I'm encountering an issue with utilizing multiple Slickgrids on a single page. With the number of grids changing dynamically, I generate them within a JavaScript function and maintain them in a grid array as shown below.

var columns = [];
var options = [];
for(var i=0; i<value; i++){
   options[i] = {
    editable: true,
    enableAddRow: true,
    enableCellNavigation: true,
    asyncEditorLoading: true,
    autoEdit: false,
    forceFitColumns: false,
    //fullWidthRows: true,
    syncColumnCellResize: true,
    rerenderOnResize: true,
    topPanelHeight: 30,
    rowHeight: 22,
    cellHighlightCssClass: "changed",
    cellFlashingCssClass: "current-server"};
}
for(var i=0; i<value; i++) {
   columns[i].push({id: value, name: value, field: value});
   columns[i].push({id: value2, name: value2, field: value2});
   columns[i].push({id: value3, name: value3, field: value3});
}
var arrayOfGrids = [];

for(var i=0; i<value; i++) {
  dataView = new Slick.Data.DataView();
  arrayOfGrids.push(new Slick.Grid('#' + i, dataView, columns[i], options[i]));
    // ....

However, I am struggling to manage events for these grids because I believe each grid's events should be handled separately. Even if the events are meant to be the same across all grids, I am unsure how to distinguish which grid's event is being triggered.

If anyone has a solution, please assist me!

If you're not familiar with closures in JavaScript, I recommend looking them up.

One way closures can help solve your issue is:

1) Create a custom function to set up your grid

2) Call this function within your for-loop

3) Attach event listeners in the initGrid function so you always reference the correct grid (Refer to comments in the code below)

function initGrid(index)
{
  var dataView = new Slick.Data.DataView();
  var grid = new Slick.Grid('#' + index, dataView, columns[index], options[index]);
  arrayOfGrids.push(grid);
  grid.onClick.subscribe(function (e) {
     //grid variable will always refer to the clicked grid
     //index variable will always be right for this grid
     //columns[index] will always hold the columns for the clicked grid
     //...
  });
}

for(var i=0; i<value; i++) {
    initGrid(i);
    // ....
}
