java script split error

Question

I am using the onCellClick function of Sigma Grid to allow the user to select from a grid and have a form updated with the selected information.

When I try to split the record that is returned from onCellClick (which returns the record associated with the grid row) I get an "Object doesn't support this property or method" pointing to the split line.

onCellClick : function(value, record, cell, row, colNO, rowNO, columnObj, grid){
 var recordCurrent = record;
 var recordSplit = recordCurrent.split(",");
 alert("Participant is " + recordSplit[1]);
 }

If I do an alert showing the unsplit record from the onCellClick event it shows the data I expect.

I am missing something obvious. Any direction you can provide will be appreciated.

• enesunal: Check recordCurrent type if it's not string (so, it's not) you cannot split.
• Mike Robinson: Even, as Enes mentioned, if you can split it there's still a chance there won't be a value in the 2nd position

Answer 1

The error you received "Object doesn't support this property or method" would suggest that you are attempting to call .split on something that doesn't have it (not a string).

You should check that your parameters are the types you expect before you work with them:

if (typeof record !== 'string') {
 throw new Error('You must pass a string as the record to onCellClick!');
} else {
 var recordCurrent = record;
 var recordSplit = recordCurrent.split(",");
 alert("Participant is " + recordSplit[1]);
}

Upon further investigation, Sigma grid documentation states that the type of the record parameter is Object or Array, not String.

• hwilliams: Thank you. It was indeed an object. Converting it to a string using var str = "" + obj; solved the problem. Thank you again.
• jbabey: @hwilliams you're welcome. if the answer helped you and you think it will help other people with a similar problem, you should accept the answer.

Answer 2

You should perform two checks:

1) That there is actually a record

2) That the split record has more than one object in it

onCellClick : function(value, record, cell, row, colNO, rowNO, columnObj, grid){
 if (record.length) {
 var recordSplit = record.split(",");
 if (recordSplit.length > 1) {
 alert("Participant is " + recordSplit[1]);
 }
 }
}
