加载页面后加载由脚本创建的Div。

Question

How can I load a div after a page has been loaded and created by a script.

$(document).ready(function(){
   $('body').append('<div class="div_new" alt="hi">Hello World</div>');
});
$('.button').click(function(){
   alt_value = $('.div_new').attr('alt');
   alert(alt_value);
});

I'm trying to load a div created by a script.

Your click handler needs to go inside the DOM ready handler. Without doing this, you will be trying to attach the click() to an element which doesn't yet exist. Try this:

$(document).ready(function(){
    $('body').append('<div class="div_new" alt="hi">Hello World</div>');

    $('.button').click(function(){
        alt_value = $('.div_new').attr('alt');
        alert(alt_value);
    });
});
