数组 查找元素
String[] type={"JPG","jpg","bmp","BMP"};String fileTYpe="BMP"; //前提：这个数组已经排好序，否则没有意义int place=java.util.Arrays.binarySearch(type,fileType);----------------------------------------
动态添加行
<script type="text/javascript"> function addMore(){ var td = document.getElementById("more"); var br= document.createElement("br"); var input= document.createElement("input"); var button= document.createElement("input"); input.type = "file"; input.name = "file"; button.type = "button"; button.value = "移除..."; button.onclick = function(){ td.removeChild(br); td.removeChild(input); td.removeChild(button); } td.appendChild(br); td.appendChild(input); td.appendChild(button); }</script>
-------------------------------------------------------------------------------
<%String newAddress="";String[] address=(String[])request.getAttribute("address");for(int i=0;i<address.length;i++){newAddress+="'"+address+"',";}newAddress=newAddress.substring(0,newAddress.length()-1);%>
<SCRIPT language="javascript">//指定要显示的图片路径var sImgArr=new Array(<%=newAddress%>);var plImg = new Image();var gIndex = 0;function SlideImg(index){gIndex = index;if ('Microsoft Internet Explorer' == navigator.appName){document.images["slideImg"].filters.item(0).Apply();}document.images["slideImg"].src = sImgArr;if ('Microsoft Internet Explorer' == navigator.appName){document.images["slideImg"].filters.item(0).play();}}function NextImg(){//显示下一张图片gIndex = ((gIndex+1)>=sImgArr.length?0:(gIndex+1));SlideImg(gIndex);}function PrevImg(){//显示前一张图片gIndex = ((gIndex-1)<0?(sImgArr.length-1):(gIndex-1));SlideImg(gIndex);}var sid;function inislide(){//设置自动运行if(sid==null){sid = setInterval('NextImg()', 3000);}}</SCRIPT>
