Select a div by title with jQuery
提问by nick2k3
I have a webpage with a div which contains several other divs WITHOUT an ID associated to them:
我有一个带有 div 的网页，其中包含其他几个没有关联 ID 的 div：
<div id="container">
<div title ="jhon" style=" position:absolute; left: 821px; top: 778.44px; width:8px; height:9px; z-index:3;"> </div>
<div title ="carl" style=" position:absolute; left: 561px; top: 579.88px; width:8px; height:9px; z-index:3;"> </div>
</div>
I need to be able to search one of these div by title and then access its style attributes such as left and top.
我需要能够按标题搜索这些 div 之一，然后访问其样式属性，例如左和顶。
I am using jQuery but I have no idea on how to select an element by name. I've tried something like:
我正在使用 jQuery，但我不知道如何按名称选择元素。我试过这样的事情：
var c =$('div[title~="john"]');
alert(c); //I get [object Object]
alert(c.style.left) // throws an error and is undefined
but it seems not to work.
但它似乎不起作用。
Any help?
有什么帮助吗？

alert( $("div[title=\"john\"]").css("left") );
alert( $("div[title=\"john\"]").css("top") );
or, if the name is a variable:
或者，如果名称是变量：
var name = "john";
alert($("div[title=\""+name+"\"]").css("left"));
alert($("div[title=\""+name+"\"]").css("top"));
