动态更新输入字段 javascript jquery

Question

我的添加和删除函数如下：

function AddOtherRefDoc(name, number) {
  var remove = "<a href='javascript:void(0);' onclick='removeRefDoctor(this)'>Remove</a>";
  var html = "<li><b> Referral Doctor: </b>"+name+"<b>, Referral No: </b>"+number+ " " +remove+"</li>";
opener.jQuery("#r_docs").append(jQuery(html));
}

function removeRefDoctor(el) { 
var el = jQuery(el);
if (el) { el.parent().remove(); }
else { alert("Unable to remove recipient."); }  

}

removeRefDoctor 函数删除当前元素，但我的输入字段不会更新。如何更新以下输入字段？

<ul id="r_docs" >

<% StringTokenizer rdlist = new StringTokenizer(rd,";");
   StringTokenizer rdnolist = new StringTokenizer(rdohip,";");
   while (rdlist.hasMoreTokens() && rdnolist.hasMoreTokens()) {
     String rd_split = rdlist.nextToken();
     String rdno_split = rdnolist.nextToken();  %>      
<li>Referral Doctor: <%=rd_split%><b>, Referral No: </b><%=rdno_split%> <a href='javascript:void(0);' onclick='removeRefDoctor(this)'>Remove</a></li>
<%} %>  
<input id="r_doctor" type="hidden" name="r_doctor" size="150" value="<%=rd%>">
<input id="r_doctor_ohip" type="hidden" name="r_doctor_ohip"
                                            size="60" value="<%=rdohip%>">

</ul>

Answer 1

function removeRefDoctor(el) { 
var el = jQuery(el);
if (el) { 
el.parent().remove(); 
$('#r_doctor').val('');
$('#r_doctor_ohip').val('');
}
else { alert("Unable to remove recipient."); }

你的问题有点令人困惑...但无论如何...将值插入隐藏字段...

html

<input id="testInput" type="hidden" />

js

var dataStr = "element1;element2;element3;element4";
$('#testInput').text(dataStr);
