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
}
$('div').toggle( offState, onState );
不是真的jQuery，但我为jQuery和MS AJAX做了一个漂亮的小桥梁:
Sys.UI.Control.prototype.j = function Sys$UI$Control$j(){
return $('#' + this.get_id());
}
如果你做了很多ASP，这真的很好。由于MS支持jQuery，现在有一个很好的桥接意味着它很容易做jQuery操作:
$get('#myControl').j().hide();
所以上面的例子不是很好，但是如果你正在编写ASP。NET AJAX服务器控件，使得在客户端控件实现中使用jQuery变得很容易。
异步each()函数
如果你有非常复杂的文档，在迭代过程中运行jquery each()函数会锁住浏览器，并且/或Internet Explorer弹出“是否要继续运行此脚本”消息，这个解决方案将会挽救你的一天。
jQuery.forEach = function (in_array, in_pause_ms, in_callback)
{
if (!in_array.length) return; // make sure array was sent
var i = 0; // starting index
bgEach(); // call the function
function bgEach()
{
if (in_callback.call(in_array[i], i, in_array[i]) !== false)
{
i++; // move to next item
if (i < in_array.length) setTimeout(bgEach, in_pause_ms);
}
}
return in_array; // returns array
};
jQuery.fn.forEach = function (in_callback, in_optional_pause_ms)
{
if (!in_optional_pause_ms) in_optional_pause_ms = 10; // default
return jQuery.forEach(this, in_optional_pause_ms, in_callback); // run it
};
你可以使用它的第一种方式就像each():
$('your_selector').forEach( function() {} );
可选的第二个参数让你指定迭代之间的速度/延迟，这对动画可能很有用(下面的例子将在迭代之间等待1秒):
$('your_selector').forEach( function() {}, 1000 );
记住，因为这是异步工作的，你不能依赖于迭代在下一行代码之前完成，例如:
$('your_selector').forEach( function() {}, 500 );
// next lines of code will run before above code is complete
我为一个内部项目写了这篇文章，虽然我确信它可以改进，但它满足了我们的需要，所以希望你们中的一些人会觉得它有用。谢谢- - -
说到技巧和技巧，以及一些教程。我发现Jeffery Way的这些系列教程(“jQuery绝对初学者”视频系列)非常有用。
它针对那些刚接触jQuery的开发人员。他展示了如何用jQuery创建许多很酷的东西，比如动画，创建和删除元素等…
我从中学到了很多。他展示了如何简单地使用jQuery。
现在我喜欢它，我可以阅读和理解任何jQuery脚本，即使它很复杂。
这里有一个我喜欢的例子“调整文本大小”
1 - jQuery……
<script language="javascript" type="text/javascript">
$(function() {
$('a').click(function() {
var originalSize = $('p').css('font-size'); // get the font size
var number = parseFloat(originalSize, 10); // that method will chop off any integer from the specified variable "originalSize"
var unitOfMeasure = originalSize.slice(-2);// store the unit of measure, Pixle or Inch
$('p').css('font-size', number / 1.2 + unitOfMeasure);
if(this.id == 'larger'){$('p').css('font-size', number * 1.2 + unitOfMeasure);}// figure out which element is triggered
});
});
</script>
2- CSS样式…
<style type="text/css" >
body{ margin-left:300px;text-align:center; width:700px; background-color:#666666;}
.box {width:500px; text-align:justify; padding:5px; font-family:verdana; font-size:11px; color:#0033FF; background-color:#FFFFCC;}
</style>
2 - HTML……
<div class="box">
<a href="#" id="larger">Larger</a> |
<a href="#" id="Smaller">Smaller</a>
<p>
In today’s video tutorial, I’ll show you how to resize text every time an associated anchor tag is clicked. We’ll be examining the “slice”, “parseFloat”, and “CSS” Javascript/jQuery methods.
