Question

[edit] I am NOT using jquery in this app.

Looking for a way to force preexisting links to open in a new window. But I only want to Apply this behavior to links appearing in a specific div element that has a classname but no ID

If you’re not using jQuery, first get the element that you want to apply it to.

var allDivs = document.getElementsByTagName('div');
var myDiv = null;

for (var j = 0; j < allDivs.length; j++) {
    var divClass = allDivs[j].getAttribute('class');
    if (divClass != null && divClass.indexof(THE_CLASS_NAME) >= 0) {
        myDiv = allDivs[i];
        var allAnchors = myDiv.getElementsByTagName('a');
        for (var i = 0; i < allAnchors.length; a++) {
            allAnchors[i].setAttribute('target', '_blank');
        }
    }
}
