[英]Concatenation in jQuery
var os = $.client.os; // mac
var browser = $.client.browser; // firefox
var browserversion = $.client.browserversion; // 3
$('#root').addClass( os + browser + browserversion );
.. results in <div id="root" class="macfirefox3">
. ..结果
<div id="root" class="macfirefox3">
。 How do I add spaces between them? 如何在它们之间添加空格?
$('#root').addClass( os + " " + browser + " " + browserversion );
Another variation of the same: 另一个变种:
$('#root').addClass([
$.client.os,
$.client.browser,
$.client.browserversion
].join(' '));
Considering jQuery's philosophy, the addClass method should really accept an array or multiple strings as arguments without you having to concatenate them. 考虑到jQuery的理念,addClass方法应该真正接受一个数组或多个字符串作为参数,而不必连接它们。
So here's my 2 cent plugin called addClasses, basically a wrapper around what Marko did. 所以这是我的2分插件名为addClasses,基本上是Marko所做的包装。
jQuery.fn.addClasses = function() {
var classes = [];
$.each(arguments, function(index, name) {
classes.push(name);
});
this.addClass(classes.join(' '));
};
Allows you to send any number of class names as string arguments. 允许您将任意数量的类名称作为字符串参数发送。
$('div').addClasses('message', 'greeting', 'w00t');
你需要连接空间,Falcon已经给你一个例子了
