In the past I've always used this to get a hidden column's data. I would hide the column with a css class, but the responsive feature doesn't work well with these.
var td = $('td', this);
var ID = $(td[0]).text();
So I found an alternative, by hiding the columns with these classes with the responsive feature.
"columnDefs": [
//Responsive classes
{ className: 'never', targets: 0 }, //Hide on all devices
{ className: 'all', targets: 1 }, //Show on all devices
]
and then I use either one of these.
var rowData = oTable1.fnGetData(this);
var rowData = oTable1.api().row(this).data();
//Grab the first indexed item in the list
var ID = rowData[0];
That works well if you don't have an AJAX source. It will return a comma separated list of the row data. However, when I try to use this with an AJAX source I just get [object Object] back (instead of a comma separated list) if I output the rowData variable in an alert.
How do I get the row data out of a table with an AJAX source?
It seem to be stored as string so [1, 2, 3] became [object Object] when you turn it into string. Do yourString = yourList.join(',')
and store yourString to keep the coma-separated string.
For an object:
yourString = (function () {
var list = [];
for(var i in yourList)
if(yourList.hasOwnProperty(i))
list.push(yourList[i]);
return list.join(',');
})();
The function is not needed, it's just to limit the variables scope.
I ended up using an answer I found here. Converting a JS object to an array
I can pull the entire row data from the table with this.
var rowData = oTable1.api().row(this).data();
In the console log I can see that it returns a javascript object like this.
Object { id="123456", full_name="Samuel Smith", Last_name="Smith" }
I use this function to convert the object into an array.
var array = $.map(rowData, function (value, index) {
return [value];
});
In the console log, my array would appear like this.
["123456", "Samuel Smith", "Smith"]
I can then extract any item from the array like this.
alert(array[0]);
Simplifying madvora's example:
var rowData = oTable1.api().row(this).data().to$();
rowDataArray = rowData.toArray();
