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>
