In javascript is there an easy way to target the parent of a parent?
I'm using this.parentNode
as the element of a function to select the parent, and I tried both this.parent.parentNode
and this.parentNode.parentNode
, but both simply return the direct parent.
I'm trying to affect the div surrounding the div surrounding the 'this'. I did manage to make it work using a simple loop statement that repeats the parentNode selection twice, but I assume there's a better way.
this.parentNode.parentNode
is correct, you must (with apologies!) have had a mistake in the test where you tried it.
Example: Live Copy | Source
HTML:
<div id="outermost">Outermost
<div id="inner1">Inner 1
<div id="inner2">Inner 2</div>
</div>
</div>
JavaScript:
var inner2 = document.getElementById("inner2");
display("inner2.id = " + inner2.id);
display("inner2.parentNode.id = " + inner2.parentNode.id);
display("inner2.parentNode.parentNode.id = " + inner2.parentNode.parentNode.id);
display("Try clicking the blue 'inner2' above");
inner2.onclick = function(e) {
display("Click: this.id = " + this.id);
if (this.parentNode) {
display("Click: this.parentNode.id = " + this.parentNode.id);
if (this.parentNode.parentNode) {
display("Click: this.parentNode.parentNode.id = " + this.parentNode.parentNode.id);
}
}
};
function display(msg) {
var p = document.createElement('p');
p.innerHTML = String(msg);
document.body.appendChild(p);
}
Output (assuming one clicks as directed):
inner2.id = inner2 inner2.parentNode.id = inner1 inner2.parentNode.parentNode.id = outermost Try clicking the blue 'inner2' above Click: e.target.id = inner2 Click: e.target.parentNode.id = inner1 Click: e.target.parentNode.parentNode.id = outermost
