JQuery 获取父级中的类
我确实花了几个小时使用 JQuery 尝试从类中提取一段文本，在下面的代码中您可以看到，当单击 reply 按钮时，JQuery 会查找名为 name< 的类。 /strong> 以提取一段文本，在本例中为 bob green。
我总是研究这类事情，但由于这些代码都不起作用，我陷入了困境，在下面的 JQuery 代码中，您可以看到我尝试了不同的方法来提取文本。
如果有人能帮助我解决这个问题，我将不胜感激。
<div class='replyContainer'>
<div class='image'></div>
<span>
<div class='close' title='Close'></div>
<b><font class='name'>bob green</font></b>
test message
</span>
<div class='bubble-triangle-border'></div>
<div class='bubble-triangle'></div>
<div class='info'>
<div class='reply'></div>
</div>
</div>
$(".replyContainer .reply").live('click',function(){
var replyName = "@" + $(this).parent().parent(".name").text();
});
$(".replyContainer .reply").live('click',function(){
var replyName = "@" + $(this).parent().parent().closest(".name").text();
});
$(".replyContainer .reply").live('click',function(){
var replyName = "@" + $(this).parent().parent("span font.name").text();
});
I have literally spent hours with JQuery trying to extract a piece of text from a class, in the code below you can see that when the reply button is clicked JQuery looks for a class called name in order to extract a piece of text which in this instance is bob green.
I am always one to research these type of things but since none of this code works I am stuck, in the JQuery code below you can see that I have tried different ways in extracting the text.
If anyone could help me fix this problem I would be more than grateful.
<div class='replyContainer'>
<div class='image'></div>
<span>
<div class='close' title='Close'></div>
<b><font class='name'>bob green</font></b>
test message
</span>
<div class='bubble-triangle-border'></div>
<div class='bubble-triangle'></div>
<div class='info'>
<div class='reply'></div>
</div>
</div>
$(".replyContainer .reply").live('click',function(){
var replyName = "@" + $(this).parent().parent(".name").text();
});
$(".replyContainer .reply").live('click',function(){
var replyName = "@" + $(this).parent().parent().closest(".name").text();
});
$(".replyContainer .reply").live('click',function(){
var replyName = "@" + $(this).parent().parent("span font.name").text();
});

其他一些事情：
.delegate()或 .on()代替。标签，而应该使用 CSS！closest()向上查找 DOM 父级及其父级，而find()向下查找子级！A few other things:
.delegate()or .on()instead.<font>tag but use CSS!closest()goes up the DOM parents and their parents, andfind()goes downward and looks at children!
