jQuery专注于append元素

Question

I want to focus an element with Jquery created by an append. My exemple :

$("#Collaps").append('<a id="link_tuiles_1" href="test.php">Link</a>')

$("#link_tuiles_1").focus(function(){       
alert('ok');   
});

---

<div id="Collaps"></div>

But it doesn't works. Could you help me ?

It will not work because you bind the function before the element is inserted on page, try it like this

("#Collaps").append('<a id="link_tuiles_1" href="test.php">Link</a>')

$(document).on("focus","#link_tuiles_1",function(){       
 alert('ok');   
});
