jQuery动态填充表格数据的表单字段 [英] jQuery dynamic fill in form fields with table data

问题描述

我使用表格在模态框中创建了一个表单。当你点击一个表格行时，它会在父页面上填充一个表单。这很好，但当我点击另一个表格行时，我无法获取值的变化。因为我使用的是ID，所以它只取第一个表格行的值。我愿意改变班级，但我尝试过，并没有帮助。

请任何人都可以帮助我。

带表格的模态表格

 < div id =modal_formtitle =地址搜索> 
< form id =modal_form> 
< ul> 
< li>< label for =name>按照街道描述搜索< / label> 
< input type =textname =street_descriptionid =street_description/> 
< input type =buttonid =search_buttonclass =form_buttonvalue =Search>< / li> 
< / ul> 
< table width =100％border =0cellspacing =0cellpadding =0id =table-data> 
< tbody>< tr> 
< td width =200px>< a href =＃>街< / a>< / td> 
< td width =200px>< a href =＃>郊区< / a>< / td> 
< td width =200px>< a href =＃>城市< / a>< / td> 
< / tr> 
< tr> 
< td id =address_street> Harambee Road< / td> 
< td id =address_suburb> Onerai< / td> 
< td id =address_city> Onerai Rural< / td> 
< / tr> 
< tr> 
< td id =address_street> Hutchinson Road< / td> 
< td id =address_suburb> Onerai< / td> 
< td id =address_city> Onerai Rural< / td> 
< / tr> 
< tr> 
< td id =address_street> Kauri Road< / td> 
< td id =address_suburb> Onerai< / td> 
< td id =address_city> Onerai Rural< / td> 
< / tr> 
< / tbody>< / table><！ -  / table＃table-data  - > 
< / form> 
  

Javascript（这是我需要区分表格行的地方）

 < script type =text / javascript> 
 $（document）.ready（function（）{
 $（'＃table-data tr'）。click（function（）{
 $（'＃street_name'）。val $（'＃address_street'）。text（））
 $（'＃suburb'）。val（$（'＃address_suburb'）。text（））
 $（'＃city'）。 val（$（'＃address_city'）。text（））}）
}）; 
< / script> 
  

父窗体，其中填充表单字段

 < form id =profile> 
< ul> 
< li>< label for =street_number> Street Number< / label>< input id =street_numbertype =textplaceholder =Street Numbername =street_number> < input type =buttonclass =form_buttonid =find_addressvalue =Find Address>< / li> 
< li>< label for =street_name>街道名称< / label>< input id =street_nametype =textplaceholder =Street Namename =street_name 已禁用>< / li> 
< li>< label for =suburb>郊区< / label>< input id =suburbtype =textplaceholder =Suburbname =suburbdisabled =disabled >< / li> 
< li>< label for =city>城市< / label>< input id =citytype =textplaceholder =Cityname =citydisabled =disabled >< / li> 
< li>< input type =submitid =submitvalue =Save>< / li> 
< / ul> 
< / form>

解决方案

ID必须是唯一的，所以这不会起作用：

  < td id =address_street> Harambee Road< / td> 
 ... 
< td id =address_street> Hutchinson Road< / td> 
  

我会给每个行一个ID，这些列使用相同的 class ：

 < tr id =row1> 
< td class =address_street> Harambee Road< / td> 
< td class =address_suburb> Onerai< / td> 
< td class =address_city> Onerai Rural< / td> 
< / tr> 
< tr id =row2> 
< td class =address_street> Hutchinson Road< / td> 
< td class =address_suburb> Onerai< / td> 
< td class =address_city> Onerai Rural< / td> 
< / tr> 
< tr id =row3> 
< td class =address_street> Kauri Road< / td> 
< td class =address_suburb> Onerai< / td> 
< td class =address_city> Onerai Rural< / td> 
< / tr> 
  

您的JavaScript会变成这样：

 < script type =text / javascript> 
 $（document）.ready（function（）{
 $（'＃table-data tr'）。click（function（）{
 var curRowId = $（this）.attr（ id）; 
 $（'＃street_name'）。val（$（'＃'+ curRowId +'td.address_street'）。text（））; 
 $（'＃suburb'） .val（$（'＃'+ curRowId +'td.address_suburb'）。text（））; 
 $（'＃city'）。val（$（'＃'+ curRowId +'td.address_city' ）.text（））; 
}）; 
}）; 
< / script> 
  

I have created a form in a modal box with a table. When you click on a table row it populates a form on the parent page. This is working great but I can't get the values to change when I click on another table row. Because I'm using IDs it only takes the values from the first table row. I am open to changing to classes but I tried this and it didn't help.

Please can anyone help me with this. The code is below.

Modal Form with Table

<div id="modal_form" title="Address Search">
<form id="modal_form">
<ul>
    <li><label for="name">Search by street description</label>
        <input type="text" name="street_description" id="street_description" />
        <input type="button" id="search_button" class="form_button" value="Search"></li>
</ul>
<table width="100%" border="0" cellspacing="0" cellpadding="0" id="table-data">
              <tbody><tr>
                <td width="200px"><a href="#">Street</a></td>
                <td width="200px"><a href="#">Suburb</a></td>
                <td width="200px"><a href="#">City</a></td>
              </tr>
              <tr>
                <td id="address_street">Harambee Road</td>
                <td id="address_suburb">Onerai </td>
                <td id="address_city">Onerai Rural</td>
              </tr>
              <tr>
                <td id="address_street">Hutchinson Road</td>
                <td id="address_suburb">Onerai </td>
                <td id="address_city">Onerai Rural</td>
              </tr>
              <tr>
                <td id="address_street">Kauri Road</td>
                <td id="address_suburb">Onerai </td>
                <td id="address_city">Onerai Rural</td>
              </tr>
        </tbody></table><!-- /table#table-data -->
</form>

Javascript (This is where I need to differentiate between the table rows)

<script type="text/javascript">
$(document).ready(function() {
$('#table-data tr').click(function () {
$('#street_name').val( $('#address_street').text() )
$('#suburb').val( $('#address_suburb').text() )
$('#city').val( $('#address_city').text() )})
});
</script>

Parent Form, where the form fields are populated

<form id="profile">
<ul>
<li><label for="street_number">Street Number</label><input id="street_number" type="text" placeholder="Street Number" name="street_number" ><input type="button" class="form_button" id="find_address" value="Find Address"></li>
<li><label for="street_name">Street Name</label><input id="street_name" type="text" placeholder="Street Name" name="street_name"  disabled="disabled" ></li>
<li><label for="suburb">Suburb</label><input id="suburb" type="text" placeholder="Suburb" name="suburb"  disabled="disabled" ></li>
<li><label for="city">City</label><input id="city" type="text" placeholder="City" name="city" disabled="disabled" ></li>
<li><input type="submit" id="submit" value="Save"></li>
</ul>
</form>

Thanks for any help you can give, cheers

解决方案

IDs must be unique, so this is not going to work:

<td id="address_street">Harambee Road</td>
...
<td id="address_street">Hutchinson Road</td>

I would give each of the rows an ID, and have all of the columns use the same class:

<tr id="row1">
  <td class="address_street">Harambee Road</td>
  <td class="address_suburb">Onerai </td>
  <td class="address_city">Onerai Rural</td>
</tr>
<tr id="row2">
  <td class="address_street">Hutchinson Road</td>
  <td class="address_suburb">Onerai </td>
  <td class="address_city">Onerai Rural</td>
</tr>
<tr id="row3">
  <td class="address_street">Kauri Road</td>
  <td class="address_suburb">Onerai </td>
  <td class="address_city">Onerai Rural</td>
</tr>

Your JavaScript would change to be like this:

<script type="text/javascript">
  $(document).ready(function() {
    $('#table-data tr').click(function () {
      var curRowId = $(this).attr("id");
      $('#street_name').val( $('#' + curRowId + ' td.address_street').text() );
      $('#suburb').val( $('#' + curRowId + ' td.address_suburb').text() );
      $('#city').val( $('#' + curRowId + ' td.address_city').text() );
    });
  });
</script>
