本文旨在大家对select和模拟select有一个全面地了解,使此项技术能发挥出更高的水平。
最初的select的确很平淡,就是一个下拉选项列表:

日久天长之后,人们对select要求高了,要修一修边幅:

function getI(ObjId) {//取得objId的最后一位数字 
 for (i=0;i<ObjId.length;i++) { 
  if (ObjId.charAt(i)=="_") return ObjId.substr(i+1,ObjId.length-1); 
 } 
 return 0; 
}

function select_edit(TextObj){//鼠标经过高亮度  
 TextObj.focus();TextObj.select(); 
}

function checkValue(ID){    
 var sl=document.all["ZfText_"+ID];  
 var sv=document.all["ZfDiv_"+ID]; 
 var da=document.all["ZfData_"+ID];    
 sv.style.display='' 
  
 for(i=0;i<da.rows.length;i++)da.rows[i].style.display='' 
  
 for(i=0;i<da.rows.length;i++){ 
  if(da.rows[i].cells[0].innerText.indexOf(sl.value)!=0)da.rows[i].style.display='none'; 
  getPosition(ID); 
 }  
}

function hiddenDiv(){ 
 var o=window.event.srcElement.id; 
 var tb  
 var sv  
 if(o=="") { 
  for (j=0;j<getDivCount();j++) { 
   tb=document.getElementById('ZfData_'+j); 
   sv=document.getElementById('ZfDiv_'+j);    
   for(i=0;i<tb.rows.length;i++) tb.rows[i].style.display=''; 
   sv.style.display='none';    
  } 
   
 }

}//隐藏模拟层

function setValue(obj){ 
var i=getI(obj.parentElement.parentElement.parentElement.id); 
//alert(obj.parentElement.parentElement.parentElement.id);

var sl=document.all["ZfText_"+i]; 
var sv=document.all['ZfDiv_'+i]; 
sl.value=obj.innerText; 
sv.style.display='none'; 
//sldIndex=obj.parentElement.rowIndex; 
}//给文本框赋值

function over(obj){ 
 obj.className="td_over" 
 obj.title=obj.innerText 
 obj.focus(); 
}//鼠标经过变色

function out(obj){ 
 obj.className="td_out" 
}//鼠标离开还原

function String.prototype.Trim(){return this.replace(/(^\s*)|(\s*$)/g,'')}//自定义去空格函数Trim()

//增加list的接口,ID表示该组控件是页面中的第几个 
function add(v,ID){ 
var sv=document.all['ZfDiv_'+ID]; 
if(!v.Trim()){return;} 
var tb=document.all['ZfData_'+ID]; 
var c=tb.insertRow(tb.rows.length).insertCell(); 
c.innerHTML='<nobr>'+v.Trim()+'</nobr>'; 
c.onmouseover=new Function("over(this)"); 
c.onmouseout=new Function("out(this)"); 
c.onclick=new Function("setValue(this)"); 
c.className="td_out"; 
v=''; 
} 
//增加inpnubox的接口,在页面中产生一个inputbox控件,下拉列表为空 
function addText(name,DefValue) { 
 var i=getDivCount(); 
 document.write('<span id="ZfSpan_'+i+'" style="border:1 solid #9CA0CB">'); 
 document.write('<input type="text" value="'+DefValue+'" name="'+name+'" id="ZfText_'+i+'" ondblclick="ZfDrop_'+i+'.click()" class="slv" onmouseover="select_edit(this)"  onkeyup="checkValue('+i+')"><input type=button id="ZfDrop_'+i+'" value=">" onclick="this.hideFocus=true;dropDown('+i+');" class="down" onmouseover="this.style.backgroundColor=#EEF3FD" onmouseout="this.style.backgroundColor=\'\'" onmousedown="this.style.backgroundColor=#ABC4F5" onmouseup="this.style.backgroundColor=\'\'"></span>');
