How to count inside jQuery.each where specific value is 1

How to count Array where value=1 inside jQuery.each?

This is my Array: result[index].isopen

This is my Code:

jQuery.each(result, function(index, item) {

console.log(result[index].isopen);  

)};

This is the console.log:

0
1
1

How to create a var that counts the results where result[index].isopen = 1? In this case it will be 2.

You can create a variable before the jQuery.each line and increment it:

var openCount = 0;

jQuery.each(result, function(index, item) {
    if (item.isopen) {
        openCount++;
    }
});

console.log(openCount);

You also need to fix your closing line of the each from )}; to });

You can also just do this with vanilla JS using the filter function to filter the items and then check the length of the filtered array:

var openResults = results.filter(function (item) {
    return item.isopen;
});

console.log(openResults.length)

Just declare the variable before the loop and increment inside the loop.

var count = 0;
jQuery.each(result, function(index, item) {

   if (item.isopen) {
      count++;
   }

});

console.log(count);
