    jQuery – get javascript object

    on Apr 11, 2016

    jQuery when applied on a css selector, returns a wrapper object which contains 0 or more javascript objects. To get the javascript object from it, we can take its 0-indexed item.

    var jsObject= $(".box")[0];
    

    The value will be undefined if there is no object. In case there are multiple javascript objects, it returns first object. Similarly we can get other javascript objects by taking 1,2,… indexed items.

    Example

    <script src="//ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
    
    <div class="box"></div>
    <pre id="msg"></pre>
    
    <script>
    var $jqObject = $(".box");
    var jsObject = $jqObject[0];
    if (jsObject) {
      $("#msg").text(jsObject.nodeName);
    }
    </script>
    refresh done
    try it online
