onclick get this textContent of an element

问题

<div class="myclass">
<ul>
<li><a> first node <i>textContent</i></a></li>
<li><a>textContent1</a></li>
<li><a>textContent2</a></li>
<li><a>textContent3</a></li>
</ul>
</div>

JS

$(".myclass ul li").live("click", function() {
alert(this.textContent);
});

I wish to get the value of <a> element using onclick

and first <li> I wish to get the value of <i> element.

Is it possible?

回答1:

use text() :

$(document).on("click", ".myclass ul li", function() {
    var txt = $('i', this).length ? $('i', this).text() : $(this).text();
    alert( txt );
});

FIDDLE

Also, live() has been deprecated and removed, and to get the text of the i element if such an element exists, you check if exists and the act appropriately
