Array count

Thu Feb 13, 2014 3:20 pm

Hello!
I created service (screen in attachments) - http://www.goldbeltbyway.com/api/feed...

How can I get length of array? On responce mapping I use this code:

//tour_cluster
if (value.field_cluster_tour_nids) {

 var itemCount = value.field_cluster_tour_nids.field_cluster_tour_nid.length; 
 console.log('itemCount : ' + itemCount); 
 for (var i = 0; i < itemCount; i++)  
 { 
     var tourID = value.field_cluster_tour_nids.field_cluster_tour_nid[i]; 
     console.log('tour: ' + tourID + ' cluster: ' + value.nid); 
     //fillTourClusterWithValues (tourID, value.nid); 
 } // end for

}
For ID 108 count is 2, BUT..... for 107 is two also! I noticed, that for 107 element is STRING, not array. Why? What is the correct way? log in attachments.
Thanks!

Hi Ivan,

You should check if your variable is an object:
preif (typeof === "object")/pre
The returned length=2 is a string length.

Hi, Katya.
Thank you! I made check if "string". But I had doubts if it is right.

Hello! Yes, you're right. Should be something like this preif (value.field_cluster_tour_nids && value.field_cluster_tour_nids.field_cluster_tour_nid) {
if (typeof value.field_cluster_tour_nids.field_cluster_tour_nid === 'string') {
console.log('itemCount : ' + itemCount);
console.log('tour: ' + value.field_cluster_tour_nids.field_cluster_tour_nid + ' cluster: ' + value.nid);
} else {
var itemCount = value.field_cluster_tour_nids.field_cluster_tour_nid.length;
console.log('itemCount : ' + itemCount);
for (var i = 0; i < itemCount; i++) {
var tourID = value.field_cluster_tour_nids.field_cluster_tour_nid;
console.log('tour: ' + tourID + ' cluster: ' + value.nid);
//fillTourClusterWithValues (tourID, value.nid);
} // end for
}
} /pre
