How to check in array has more then one value

[lucky24]

Hi Team,

I am storing value in array and I have to check array has more then one value.

If array has only one value then I have to store value in choice field but If array has more then value then I have to store in list collector.

var asm = new GlideRecord('asmt_metric_result');
asm.addQuery('metric.name','Improvement');
asm.addQuery('instance',current.sys_id); //
asm.query();
while(asm.next()) {
arr.push(asm.string_value +",");
}

How can I check array has more then one value or one value and store according validation?

Please help me here?

Hi @lucky24 

Use arr.length>1 to check if it has more than 1 value

Hi @lucky24 you can use length() method to see how many values are present in array.

arr.length --> this will give you the total array values,  so you can check arr.length>1 // to check more than one value

Hi,

You can use if(arr.length>1){}
