/*----------------------------------------------------------//
iLinkTarget(id,successFn);设定一链接打开的页面结果显示一个html元素中
	id:要显示结的元素ID
	successFn:页面请求成功后执行的函数（可选）,参数:xThis为链接对象（DOM）;id为显示结果元素的ID

iHover(className1,className2);设定鼠标hover样式
	className1:初始Class
	className2:悬停Class

iUpFile(fn);
	jQuery上传文件,调用方法:jQuery(form).upFile(function);form为文件框所在的form,function为回调函数,函数参数为返回的文本值
iFormsubmit(fn);上传表单，fn为回调函数

iURL(url);
	请求url的结果赋值与一jQuery对象


inu.link();查找有iTarget的a标签，将链接的结果显示在iTarget目标中

iGetPosition();返回一个元素的位置数组，[0]为left,[1]为top

Event.pointerX(event);Event.pointerY(event);//鼠标所在位置

inuLoad.css(file);加载一个css文件，并添加到页面
inuLoad.html(file);加载一个HTML，返回HTML文本

xiaoliMoveDiv(target);设置一对象可移动,target为目标(默认为自已)

xiaoliCenter();设置一对象居中

oscillate(length,time,position,fn);振动，length振动像素，time持继时间,position:left、top,默认为top,fn执行完调用的函数

addOption(json);json如是json[{"text":"1","value":"2"}]则add到select,如是string就当作url进行请求;

clearOption()//清空select中的option

association(oSelect,url)//关联一个select,oSelect:被关联的select,url,值所在的url

inu.fileStyle();用于设置file样式的,文件框必须在<label class="fileOut"></lable>里，label会被设置为block
