Question

jquery each方法里面循环数组对里面的每一个元素绑定live事件不可用，请教是怎么回事？

$this.find(":text[format]").each(function ()
{
var format = $(this).attr('format');
if (format_notices[format]['key'])
{
$(this).live('keypress', eval('keypress_' + format));
}
else
{
return false;
}

}); //绑定键盘验证事件
thank you all the way!
你改的那个方法改是不行。
$this.find(":text[format]")是一个数组。是对其每一个元素绑定live。其次bind是可以绑定上的，live和livequery都不行。

Answer 1

live绑定事件是针对选择器的，比如:
$("a").live("click",function(){...});
而不能使用$("body").find("a").live("click",function(){...});来进行绑定，不能以筛选的方式锁定元素范围。同时live绑定的事件是有限制（click, dblclick, keydown, keypress, keyup, mousedown, mousemove, mouseout, mouseover, mouseup, hover*）。

Answer 2

首先你的理解live的作用啊，还有就是each函数不是怎么用的，我帮你改下，你看看：
$this.find(":text[format]").live('keypress', function(){
var format = $(this).attr('format');
if(format_notices[format]['key']){
eval('keypress_' + format);
}
else
{
return false;

}
);

.live() doesn't work this way, it attaches handlers up at the document level and listens for when events bubble up. A new element, old element, it doesn't matter...they all bubble events the same way. The common misconception is that .live() attach events as elements are added...this isn't the case. Just because of how it works, .each() can't be used in this way.
