blocks|key|952850|text|您需要先编写一个选择器来选择正确的<input>。理想情况下，使用元素的ID+$('#element_id')，否则使用它的容器$('#container_id+input')的ID或元素的类$('input.class_name')。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|952851|您的元素没有这些，也没有上下文，所以很难告诉您如何选择它。|952852|一旦找到了合适的选择器，就可以使用attr方法来访问元素的属性。要获取名称，您可以使用返回(在您的示例中)+'xxxxx'的$(selector).attr('name')。|952853|entityMap|0|LINK|mutability|MUTABLE|url|http://api.jquery.com/attr/^0|H|7|13|G|1S|O|2O|L|0|0|1I|7|1Q|O|H|4|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@$9|S|A|T|B|C]|$9|U|A|V|B|C]|$9|W|A|X|B|C]|$9|Y|A|Z|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|10|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|11|8|@$9|12|A|13|B|C]|$9|14|A|15|B|C]]|D|@$9|16|A|17|1|18]]|E|$]]|$1|J|3|-4|5|6|7|19|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q]]]]

<p>You need to write a selector which selects the correct <code>&lt;input&gt;</code> first.  Ideally you use the element's ID <code>$('#element_id')</code>, failing that the ID of it's container <code>$('#container_id input')</code>, or the element's class <code>$('input.class_name')</code>.</p>

<p>Your element has none of these and no context, so it's hard to tell you how to select it.</p>

<p>Once you have figured out the proper selector, you'd use the <a href="http://api.jquery.com/attr/" rel="noreferrer">attr</a> method to access the element's attributes.  To get the name, you'd use <code>$(selector).attr('name')</code> which would return (in your example) <code>'xxxxx'</code>.</p>


blocks|key|1167131|text|更好的方法可能是使用'this'，它接受'id‘的任何名称并使用它。只要添加名为'mytarget‘的类名即可。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1167132|每当目标字段发生变化时，它都会显示一个带有该字段名称的警告框。只需剪切并通过整个脚本，它就能正常工作！|1167133|<script+src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"+type="text/javascript"></script>

<p>A better way could be using 'this', it takes whatever the name of the 'id' is and uses that. As long as you add the class name called 'mytarget'.  </p>

<p>Whenever any of the fields that have target change then it will show an alert box with the name of that field. Just cut and past whole script for it to work!</p>

<pre><code>&lt;script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"&gt;&lt;/script&gt;
&lt;script&gt;
$(document).ready(function() {
 $('.mytarget').change(function() {
var name1 = $(this).attr("name");
alert(name1);
 });
});
&lt;/script&gt;

Name: &lt;input type="text" name="myname" id="myname" class="mytarget"&gt;&lt;br /&gt;
