Hi i want to get changed text value from JQuery but i can't select edit text with JQUERY because edit texts generated from php while loop that this php code query on database and get value of edit texts and in my program i have edit button for every edit texts and when the user changed value of edit text i select new value and when user click edit button send this value from get method to another php page with jquery $.ajax
function and send new value to that php code with ajax.But i don't know how can i select edit text that it's value changed because i don't know id of that edit text!.And when i set one id for every edit text i only get first edit text value from $("#id").change().val();
.I use below code but it doesn't work.I am beginner in java script and don't know how fix this problem!.
var testAnswer;
function setNewTestAnswer(id){
testAnswer = $("#id").val();
}
function sendToEdit(pID,phID,thDate,type){
var info = 'pId='+pID+'&phId='+phID+'&testAnswer='+testAnswer+'&thDate='+thDate+'&type='+type;
}
2nd function use testAnswer that user changed in edit text.
php code
<?php
include 'Connect.php';
if(match($_POST['pId'], "/^[\d]+$/") ){
$pId = $_POST['pId'];
$result = mysql_query("select pName, pID, phName, phID, testHistoryDate, type, testAnswer from patient join reception using(pID) join physician using(phID) join testHistory using(rID) join test using(tID) where pID = $pId",$connection);
}
else
die("Insert true value");
while($row=mysql_fetch_array($result)){
echo "<tr><td>";
echo $row["pName"].'</td>';
echo '<td>'.$row["phName"].'</td>';
echo '<td>'.$row["testHistoryDate"].'</td>';
echo '<td>'.$row["type"].'</td>';
$type = $row['type'];
$testHistoryDate = $row['testHistoryDate'];
?>
<td>
<span id='spryTanswer'>
<input type='text' name='tAnswer' id='tAnswer' value='<?php echo $row['testAnswer']; ?>' />
</span>
</td>
<td>
<input type='submit' value='Edit' name='edit' id='edit' onclick="sendToEdit('<?php echo $row['pID'] ?>','<?php echo $row['phID'] ?>', '<?php echo $row['testHistoryDate'] ?>', '<?php echo $row['type'] ?>')" />
</td>
</tr>
<?php } ?>

Since you're creating elements inside a php loop, you must be sure that every element has a unique id (or no id at all). You can use either an incrementing index, or some unique value in your array. At first glance, seems that $row['pID']
is a good candidate:
<input id='edit_<?php $row['pID'] ?>' type='submit' value='Edit' ... />
After that you should be able to target individual elements.

tl;dr
So it isn't completely clear what you are trying to do here but I can explain a couple things that might help.
in html ids should be unique. You dont have to obey this rule for your page to work but you have found one of the consequences if breaking it: jQuery will only find the first one.
it is a good idea to base html ids on some unique attribute of your data eg the table row id.
You can get more creative with your jQuery selectors for example
$('input[type="text"]') // gets all the text inputs
Use classes. When you want to be able to easily select all of a group of html elements you should give them all the same class name. one element can have multiple class names and many elements can share a class name. you can then select them by class name using jquery like this:
$('.myclassname')
I think you need to change your php to look more like this:
<span class='spryTanswer'>
<input type='text' name='tAnswer' id='tAnswer-<?php echo $row['id'] ?>' value='<?php echo $row['testAnswer']; ?>' />
</span>
