很多时候,不知道需要表单的数目,就需要能对表单进行数量的控制。收集了如下两个效果:
效果1:
<html><body><form name="form1"><table id="tb1" border=0> <tr><td><a href="#" >添加附件</a></td></tr></table><input type="hidden" name="fjCnt" value="1" /></form></body></html><script language="javascript"> function addFj() { var oTb = document.getElementById("tb1"); var oTr = oTb.insertRow(0); var name = "thefilename"+document.form1.fjCnt.value; document.form1.fjCnt.value=parseInt(document.form1.fjCnt.value)+1; oTr.insertCell(0).innerHTML = "<input id='file' name='"+name+"' type=file style='width:400px;'> <input type=button >" return false; } function delFj(obj) { obj.parentElement.parentElement.removeNode(true); return false; }</script>
[Ctrl+A 全部选择 提示:你可先修改部分代码,再按运行]
效果2:
