How to get the parent element value using jquery?

问题

I have a table with a couple of rows with two cells in each row and each cell has couple of info like office name, address and phone number etc. Using jquery for each, the address is being pulled out from each cell and fed into google map geocoder object to get the point and plot it in the map. Now at each hit of an Address value, I would also like to grab the unique value of phone and office name from the current cell from which jquery is getting address value..I need those values so i can display those values in the InfoWindow of the map? How do I get those values?

<table class="OfficeInfo" border="0" style="width: 100%" cellspacing="10px" cellpadding="15px">
  <tr>
    <td class="Office1" style="width=40%">  
     <span class="OfficeName">

回答1:

Depending on the current context of this, then this should work:

$(this).parent().find('.officeName').html();

回答2:

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

回答3:

We can do this by using jquery OR Javascript. here we are going to discuss with email id updates.

in bellow example a pop up window will open with auto fill email id from parent window. after update, a email will automatically update in parent window text box and pop up window will have closed autocratically.

Example:

1) Create file index.html as a parent windows

<!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=”demo@demo.com”></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) Create file update_popup.html as a pop up window where email id auto fill from parent window for update.

<!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>
