how to link Search plug-in with data table object?

soosaijebasteen

I have two data tables in a page.Both tables are nearly identical. But one is for dev and another one for release info.

I added search plugin in javascript.

$.fn.dataTable.ext.search.push(function (settings, data, dataIndex) {
var min = $('#pmin').datepicker("getDate");
var max = $('#pmax').datepicker("getDate");
var startDate = new Date(data[dateColNo]);
if (min == null && max == null) { return true; }
if (min == null && startDate <= max) { return true; }
if (max == null && startDate >= min) { return true; }
if (startDate <= max && startDate >= min) { return true; }
return false;
});

$.fn.dataTable.ext.search.push(function (settings, data, dataIndex) {
var min = $('#dmin').datepicker("getDate");
var max = $('#dmax').datepicker("getDate");
var startDate = new Date(data[dateColNo]);
if (min == null && max == null) { return true; }
if (min == null && startDate <= max) { return true; }
if (max == null && startDate >= min) { return true; }
if (startDate <= max && startDate >= min) { return true; }
return false;
});

This is not working correctly because these search plugins are no way connected to correct data table.

How to link first search for one table and second for another table??

@kthorngren,
Thanks for your reply.
Now I did like this.

function addFilter() {
$.fn.dataTable.ext.search = [];
$.fn.dataTable.ext.search.push(
function (settings, data, dataIndex) {
if (settings.nTable.id === "pTable") {
var min = $('#pmin').datepicker("getDate");
var max = $('#pmax').datepicker("getDate");
var startDate = new Date(data[dateColNo]);
if (min == null && max == null) { return true; }
if (min == null && startDate <= max) { return true; }
if (max == null && startDate >= min) { return true; }
if (startDate <= max && startDate >= min) { return true; }
return false;
} else if (settings.nTable.id === "dTable") {
var min = $('#dmin').datepicker("getDate");
var max = $('#dmax').datepicker("getDate");
var startDate = new Date(data[dateColNo]);
if (min == null && max == null) { return true; }
if (min == null && startDate <= max) { return true; }
if (max == null && startDate >= min) { return true; }
if (startDate <= max && startDate >= min) { return true; }
return false;
}
return false;
}
);
}

I'm calling this add filter before I call table.draw for both pTable or dTable.

$("#pmin").keyup(function () {
addFilter(); pTable.draw();
});

$("#dmin").keyup(function () {
addFilter(); dTable.draw();
});

like this.

Now I don't encounter that issue. But still is this the proper way to do it.

Or if any improvements to the code can be done, kindly let me know.

I passed tableElement which is pTableElement = $("#pTable"); and pTableElement .DataTable() object.

if (settings.nTable.id == tableElement.nativeElement.id) {}

I received error: unkown property id.

That is why used if (settings.nTable.id === "dTable") {} straighaway.
