小弟在开发一个系统php+mysql.目前只剩一下一个问题,问题测试页面如下

http://www.fashion.ntut.edu.tw/mio/test.php

上方表单为销售资料上传用,预设报告数量(Report Number)为1,就是上传一笔资料,
而在Channel Type跟store name中我是使用二层动态下拉选单,store name会依据Channel Type不同而改变,会筛选出资料

问题在于当我选择将报告数量选择为2以上,就是上传多笔纪录的时候(上传多笔我用回圈达成),二阶动态选单的功能就失效了?只有第一笔报告正常

report no.2..等表单的动态选单都失效....如下图所示






动态选单我是利用DW的mxp做的

我的动态选单是当下拉class1选单时会将其分类的厂商名称动态过滤到c_name下拉选单中,
首先class1的程式码如下,当下拉选单改变时触发FilterAndPopulateSubList()

复制程式
<select name="class1[]" id="class1" onChange="WA_FilterAndPopulateSubList(c_name2_WAJA,MM_findObj('class1'),MM_findObj('C_name'),1,0,false,':')">
<option value="" <?php if (!(strcmp("", ((isset($_POST["class1"]))?$_POST["class1"]:"")))) {echo "selected=\"selected\"";} ?>>-Channel Type-</option>

FilterAndPopulateSubList()与MM_findObj()如下

复制程式
function WA_FilterAndPopulateSubList(thearray,sourceselect,targetselect,leaveval,bottomleave,usesource,delimiter)     {
  if (bottomleave > 0)     {
    leaveArray = new Array(bottomleave);
    if (targetselect.options.length >= bottomleave)     {
      for (var m=0; m<bottomleave; m++)     {
        leavetext = targetselect.options[(targetselect.options.length - bottomleave + m)].text;
        leavevalue  = targetselect.options[(targetselect.options.length - bottomleave + m)].value;
        leaveArray[m] = new Array(leavevalue,leavetext);
      }
    }
    else     {
      for (var m=0; m<bottomleave; m++)     {
        leavetext = "";
        leavevalue  = "";
        leaveArray[m] = new Array(leavevalue,leavetext);
      }
    }
  }  
  startid = WA_UnloadList(targetselect,leaveval,0);
  mainids = new Array();
  if (usesource)    maintext = new Array();
  for (var j=0; j<sourceselect.options.length; j++)     {
    if (sourceselect.options[j].selected)     {
      mainids[mainids.length] = sourceselect.options[j].value;
      if (usesource)     maintext[maintext.length] = sourceselect.options[j].text + delimiter;
    }
  }
  for (var i=0; i<thearray.length; i++)     {
    goodid = false;
    for (var h=0; h<mainids.length; h++)     {
      if (thearray[i][0] == mainids[h])     {
        goodid = true;
        break;
      }
    }
    if (goodid)     {
      theBox = targetselect;
      theLength = parseInt(theBox.options.length);
      theServices = thearray[i].length + startid;
      var l=1;
      for (var k=startid; k<theServices; k++)     {
        if (l == thearray[i].length)     break;
        theBox.options[k] = new Option();
        theBox.options[k].value = thearray[i][l][0];
        if (usesource)     theBox.options[k].text = maintext[h] + WA_ClientSideReplace(thearray[i][l][1],"|WA|","'");
        else               theBox.options[k].text = WA_ClientSideReplace(thearray[i][l][1],"|WA|","'");
        l++;
      }
      startid = k;
    }
  }
  if (bottomleave > 0)     {
    for (var n=0; n<leaveArray.length; n++)     {
      targetselect.options[startid+n] = new Option();
      targetselect.options[startid+n].value = leaveArray[n][0];
      targetselect.options[startid+n].text  = leaveArray[n][1];
    }
  }
  for (var l=0; l < targetselect.options.length; l++)    {
    targetselect.options[l].selected = false;
  }
  if (targetselect.options.length > 0)     {
    targetselect.options[0].selected = true;
  }
}


复制程式
function MM_findObj(n, d) { //v4.01
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
  if(!x && d.getElementById) x=d.getElementById(n); return x;
}


已解决

今天有研究一下
因该是class name的问题

如果你会用AJAX来写的话
因该会比较好写
