how to loop through array with javascript

Question

I its basic but I am new to javascript. I am trying to loop through the array and match the objects that == my key.

this is what i am using right now, it works but i am only matching the first object that matches, sometimes there will be multiple objects that match.

Here is what i have now

var chartSeries = chartService.getSeries();
var marker.options.subdivision.id = 1345
var matchingSeries = Enumerable.From(chartSeries).Where('x => x.id == "' + marker.options.subdivision.id + '"').ToArray();
 var series = {
 id: matchingSeries[0].id,
 name: matchingSeries[0].name,
 data: matchingSeries[0].data,
 lineWidth: 5
 };

I need to include a for loop to match all objects.

 var subIdSeries = [];
 var subId = marker.options.subdivision.id;
 var series = {
 id: matchingSeries[0].id,
 name: matchingSeries[0].name,
 data: matchingSeries[0].data,
 lineWidth: 5
 };
 for (var i = 0; i < chartSeries.length; i++) {
 if (subId == chartSeries.id) {
 push.subIdSeries(subId)
 }
 }

• Vitalii Zurian: Should it be subIdSeries.push(subId) instead of push.subIdSeries(subId)?
• Grundy: you can use Array.map or Array.forEach or Array.filter

Answer 1

Change

if (subId == chartSeries.id) {
 push.subIdSeries(subId)
}

to

if (subId == chartSeries[i].id) {
 subIdSeries.push(subId)
}

Answer 2

Without seeing the whole script, from what you have so far, I can suggest:

if (subId == chartSeries[i].id) {
 subIdSeries.push(subId)
}
