Replace anonymous functions with named functions. This really supercedes the jQuery context, but it comes into play more it seems like when using jQuery, due to its reliance on callback functions. The problems I have with inline anonymous functions, are that they are harder to debug (much easier to look at a callstack with distinctly-named functions, instead 6 levels of "anonymous"), and also the fact that multiple anonymous functions within the same jQuery-chain can become unwieldy to read and/or maintain. Additionally, anonymous functions are typically not re-used; on the other hand, declaring named functions encourages me to write code that is more likely to be re-used.
一个例子;而不是:
$('div').toggle(
function(){
// do something
},
function(){
// do something else
}
);
我喜欢:
function onState(){
// do something
}
function offState(){
// do something else
}
$('div').toggle( offState, onState );

只要在站点上包含这个脚本,您就会得到一个Firebug控制台,可以在任何浏览器中进行调试。虽然功能不全,但还是很有用的!吃完之后记得把它拿掉。

我发现了一些新的东西;它是JQuery Hotbox。
JQuery轴承箱
谷歌在谷歌Code上托管了几个JavaScript库。从那里加载它可以节省带宽,而且加载速度很快,因为它已经被缓存了。
<script src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
// Load jQuery
google.load("jquery", "1.2.6");
google.setOnLoadCallback(function() {
// Your code goes here.
});
</script>
Or
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js" type="text/javascript"></script>
你也可以用它来判断图像何时完全加载。
$('#myImage').attr('src', 'image.jpg').load(function() {
alert('Image Loaded');
});
firebug的"console.info",您可以使用它将消息和变量转储到屏幕上,而不必使用警告框。”控制台。Time”允许你轻松地设置一个计时器来包装一堆代码,并查看它需要多长时间。
console.time('create list');
for (i = 0; i < 1000; i++) {
var myList = $('.myList');
myList.append('This is list item ' + i);
}
console.timeEnd('create list');
在方法调用(如.append())中使用自动执行的匿名函数来遍历某些内容。例如:
$("<ul>").append((function ()
{
var data = ["0", "1", "2", "3", "4", "5", "6"],
output = $("<div>"),
x = -1,
y = data.length;
while (++x < y) output.append("<li>" + info[x] + "</li>");
return output.children();
}()));
