如何使用jquery获取父元素值？

Question

我有一个表格，有几行，每行有两个单元格，每个单元格都有一些信息，如办公室名称、地址和电话号码等。每个单元格使用jquery，从每个单元格中提取地址并输入谷歌地图地理编码器对象来获取点并将其绘制在地图上。现在，在每次点击地址值时，我还想从 jquery 获取地址值的当前单元格中获取电话和办公室名称的唯一值。我需要这些值，以便我可以在 InfoWindow 中显示这些值地图？我如何获得这些值？

<table class="OfficeInfo" border="0" style="width: 100%" cellspacing="10px" cellpadding="15px">

Answer 1

$(this).siblings('.Phone').html() 和 $(this).siblings('.Address').html()

Answer 2

我们可以使用 jquery 或 Javascript 来做到这一点。在这里我们将讨论电子邮件 ID 更新。

在下面的示例中，将打开一个弹出窗口，其中会从父窗口自动填充电子邮件 ID。
更新后，父窗口文本框中将自动更新一封电子邮件，并且弹出窗口将自动关闭。

示例：

1) 创建文件index.html作为父窗口

<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN”>
<html>
<title></title>
<head></head>

<body>
<table>

<tr>
<td colspan=”2″>Example for update email id.</td>
</tr>
<tr>
<td>Email Id:</td>
<td>
<input type=’text’ name=”emailID” id=”emailId” value=”[email protected]”></td>
</tr>
<tr>
<td>
<input type=”button” name=”update” value=”Update”
onClick=’window.open(“update_popup.html”, “”, “width=400, height=300″)’>
</td>
</tr>
</table>
</body>
</html> 

2) 创建文件update_popup.html作为弹出窗口，其中电子邮件ID从父窗口自动填充以进行更新。

<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN”>
<html>
<title></title>
<head></head>
<script src=”http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js”></script>
<script>
$(document).ready(function(){

//== pre fill parent window email id in popup window for update

var emailId = window.opener.document.getElementById(“emailId”).value;
$(“#emailId”).val(emailId);

//=== update updated email id in to parent window

$(“#Save”).on(‘click’,function(){

var updated_emailId = $(“#emailId”).val();
window.opener.document.getElementById(“emailId”).value = updated_emailId;
window.close();
});
});
</script>

<body>
<table>
<tr>
<td>Email Id:</td>
<td>
<input type=’text’ name=”emailID” id=”emailId” value=””></td>
</tr>
<tr>
<td><input type=”button” name=”Save” id=”Save” value=”Save”></td>
</tr>
</table>
</body>
</html>
