How to break or continue Ext.each

Question

Ext.each(boundsExtend, function(value) {     if(value != record.ID) break; }); 

So how do I break or continue Ext.each loop?

Answer 1

From the docs:

If the supplied function returns false, iteration stops and this method returns the current index.

So as in the OP's example (assuming record is in scope and non-null):

Ext.each(boundsExtend, function(value) {   if (value != record.ID) {     return false;   }   // other logic here if ids do match }); 

Note that returning false exits the loop completely, so in this case the first non-matching record will bypass any additional checking.

However I'm guessing that what you're really trying to do is loop until you find the matching record, do some logic, then short-circuit the loop. If that's the case, the logic would actually be:

Ext.each(boundsExtend, function(value) {   if (value === record.ID) {     // do your match logic here...     // if we're done, exit the loop:     return false;   }   // no match, so keep looping (i.e. "continue") }); 

Any other value that is not explicitly false (e.g. null by default) will keep the loop going.

var countries = ['Vietnam', 'Singapore', 'United States', 'Russia'];  Ext.Array.each(countries, function(name, index, countriesItSelf) {     console.log(name); });  Ext.Array.each(countries, function(name, index, countriesItSelf) { if (name === 'Singapore') {     return false; // break here } });
