How do I iterate through children elements of a div using jQuery?

I have a div and it has several input elements in it... I'd like to iterate through each of those elements. Ideas?


Use children() and each(), you can optionally pass a selector to children

$('#mydiv').children('input').each(function () {
    alert(this.value); // "this" is the current element in the loop
});

You could also just use the immediate child selector:

$('#mydiv > input').each(function () { /* ... */ });

It is also possible to iterate through all elements within a specific context, no mattter how deeply nested they are:

$('input', $('#mydiv')).each(function () {
    console.log($(this)); //log every element found to console output
});

The second parameter $('#mydiv') which is passed to the jQuery 'input' Selector is the context. In this case the each() clause will iterate through all input elements within the #mydiv container, even if they are not direct children of #mydiv.


If you need to loop through child elements recursively:

function recursiveEach($element){
    $element.children().each(function () {
        var $currentElement = $(this);
        // Show element
        console.info($currentElement);
        // Show events handlers of current element
        console.info($currentElement.data('events'));
        // Loop her children
        recursiveEach($currentElement);
    });
}

// Parent div
recursiveEach($("#div"));   

NOTE: In this example I show the events handlers registered with an object.


$('#myDiv').children().each( (index, element) => {
    console.log(index);     // children's index
    console.log(element);   // children's element
 });

This iterates through all the children and their element with index value can be accessed separately using element and index respectively.


It can be done this way as well:

$('input', '#div').each(function () {
    console.log($(this)); //log every element found to console output
});
