how to use hide show in while loop with different ids - javascript

HTML
while($row=mysql_fetch_array($result_pag_data)) {
$ad++;
$sql1=mysql_query("select *from company where com_id='$row[com_id]'");
$row1=mysql_fetch_array($sql1);
?>
<tr>
<input type="hidden" id="comid" name="comid" value="<?php echo $row1[com_id];?>"/>
<tr>
<td><img src="images/mobile.png" width="18" height="18" border="0" alt="Mobile"></td>
<td class="comm-details"><strong>Mobile</strong></td>
<td align="center">:</td>
<td class="comm-details"><?php if($row1['mobile1']!='') { ?> <a id="showmobile<?php echo $row1[com_id];?>">View Mobile Number</a> <span id="shwmb<?php echo $row1[com_id];?>" style="display:none"><?php echo $row1['mobile1'];}else{ echo 'Not Available';}?></td>
</tr>
}
Javascript
<script>
$(function () {
var comid = $('#comid').val();
$("#showmobile" + comid).click(function() {
$("#shwmb" + comid).show();
$("#shwmb" + comid).hide();
});
});
</script>
Now I want to show the mobile number when the customer clicks on View Mobile Number. It currently only works on the first viewed company, not for subsequent companies.
When I change the event handling to listen to the class instead of the id, clicking on any one company's View Mobile Number will display the mobile numbers of all companies on the page.
Neither solution is working properly. What am I doing wrong, and how do I make this work?

Change your code as like below:
<?php
$ad = 0;
while ($row = mysql_fetch_array($result_pag_data)) {
$ad++;
$sql1 = mysql_query("select *from company where com_id='$row[com_id]'");
$row1 = mysql_fetch_array($sql1);
?>
<tr>
<input type="hidden" id="comid" name="comid" value="<?php echo $row1[com_id]; ?>"/>
<tr>
<td><img src="images/mobile.png" width="18" height="18" border="0" alt="Mobile"></td>
<td class="comm-details"><strong>Mobile</strong></td>
<td align="center">:</td>
<td class="comm-details">
<?php if ($row1['mobile1'] != '') { ?>
<a id="showmobile<?php echo $row1[com_id]; ?>" onclick="return showmobile(<?php echo $row1[com_id]; ?>)">View Mobile Number</a>
<span id="shwmb<?php echo $row1[com_id]; ?>" style="display:none">
<?php echo $row1['mobile1']; ?>
</span>
<?php
} else {
echo 'Not Available';
}
?>
</td>
</tr>
<?php }
?>
<script>
function showmobile(id) {
if($("#shwmb" + id).css('display') == 'none') {
$("#shwmb" + id).show();
}else {
$("#shwmb" + id).hide();
}
}
</script>

You have to put unique value in the ID or CLASS of the line.
<input type="hidden" id="comid<?php echo $row['ID']?>" name="comid" value="<?php echo $row1[com_id];?>"/>
and after that in the javascript code you just specify the id along with the id_name and id_value.

This might work for your purpose:
while($row=mysql_fetch_array($result_page_data)) {
$ad++;
$sql1=mysql_query("select *from company where com_id='$row[com_id]'");
$row1=mysql_fetch_array($sql1);
?>
<tr>
<td>
<input type="hidden" id="input-<?php echo $row1[com_id];?>" name="input-<?php echo $row1[com_id];?>" value="<?php echo $row1[com_id];?>"/>
<img src="images/mobile.png" width="18" height="18" border="0" alt="Mobile">
</td>
<td class="comm-details"><strong>Mobile</strong></td>
<td align="center">:</td>
<td class="comm-details"><?php if($row1['mobile1']!='') { ?> <a id="showmobile<?php echo $row1[com_id];?>" class="showmobile">View Mobile Number</a> <span id="shwmb<?php echo $row1[com_id];?>" style="display:none"><?php echo $row1['mobile1'];}else{ echo 'Not Available';}?></td>
</tr>
}
<script>
$(function () {
$(".showmobile").click(function() {
var comid = $(this).attr("id").replace("showmobile","");
$("#shwmb" + comid).toggle();
});
});
</script>
The first change is to use $row1[com_id] in the id and name attributes for the hidden input field. This will allow the hidden fields to be separate from one another, as id has to be unique on a page; name should also be unique.
Next, a class was added to the showmobile link, so that we can install a single class-level click handler. The click handler will extract the com_id from the showmobile element and use it to change the visibility of the shwmb element, using jQuery toggle.
Some light restructuring has been done and some significant reformatting. The hidden input field was added to the first td element, so that it doesn't interfere with the structure of the table.
Also, the $result_page_data variable name was corrected.

How to use PHP loop variable in javascript?

I have run an SQL statement to get all the records I need to show in a HTML table.
I have then run a while loop to display the records from the database. (The code for this is below.)
<table class="projects-table">
<tr>
<th>Complete?</th>
<th>Paid?</th>
<th>Project Name</th>
<th>£ / hr</th>
<th>End Date</th>
<th>Hours Logged</th>
<th><i class="fa fa-trash"></i></th>
</tr>
<?php
$select_id_jobs = mysqli_query($mysqli, "SELECT id FROM users WHERE username='$login_user'");
while($row = mysqli_fetch_array($select_id_jobs)) {
$id_jobs = $row['id'];
}
$select_jobs_with_usrid = mysqli_query($mysqli, "SELECT * FROM jobs WHERE username_id = '$id_jobs';");
while($row = mysqli_fetch_array($select_jobs_with_usrid)) {
?>
<tr id="<?php echo $rowId; ?>">
<td>
<!-- Complete Checkbox -->
<input type="checkbox" id="<?php echo $completeCheck;?>" onclick="compTask();">
</td>
<td>
<!-- Paid checkbox -->
<input type="checkbox" onclick="paidTask()">
</td>
<td>
<?php echo $row['project_title']; ?>
</td>
<td>
<?php echo $row['cost_hour']; ?>
</td>
<td>
<?php echo $row['completion_date']; ?>
</td>
<td>
<?php echo $row['time_spent']; ?>
</td>
<td>
<div class="delete-btn"><a onclick="deleteTask()">DELETE</a></div>
</td>
</tr>
<?php } ?>
</table>
As you can see from the checkbox for completing a task. What I want to do is use javascript so that when the checkbox is checked the text from the other records turns green.
I have included the javascript I am trying to use below. I don't know why but I can't access the inputs ID in order to change the css.
<script>
function compTask() {
if (document.getElementById("<?php echo 'complete-' . $row['id'] ?>").checked == true) {
document.getElementById("<?php echo 'tr' . $row['id']; ?>").style.color = "green";
alert("hello");
} else {
document.getElementById("<?php echo 'tr' . $row['id']; ?>").style.color = "black";
}
}
Okay easy way to do that is to print id as parameter in js function
something like that:
<input type="checkbox" id="<?php echo $completeCheck;?>"
onclick="compTask( '<?php echo $row['id'];?>' );">
and in js function deal with id from parameter:
function compTask(id) {
if (document.getElementById('complete-' + id).checked == true) {
document.getElementById('tr' + id).style.color = "green";
alert("hello");
}
}
Hy,
You need to add id in onclick="deleteTask('<?php echo $row['id']; ?>')">
Now in you function have id:
function deleteTask(id) { console.log(id) }

How to add a new input (type = "submit" value="delete") with a new action (before the "join" button) whenever the $_POST['submit'] is set? I don't want to add a new input before each "join" button. Instead, I just want to add after a specific "join" button inside a cell when that specific "join" button is clicked. Also, if I click another 'join' button in other cell, a similar effect would happen too. So in the end, after clicking two "join" button, there should be only two delete button each added before the specific clicked "join" buttons. How to solve it ?
Thanks a lot :)

department table
dept_ID dept_name
1 Account
2 Finance
3 Marketing
Assume that my department table only have 3 records.
My requirement is the following:
- Click 1st delete button, show department ID = 1
- Click 2nd delete button, show department ID = 2
- Click 3rd delete button, show department ID = 3
However from my code, I can't meet my requirement. The department ID output that I get is 1 no matter what button I clicked.
Can someone help me?
No need to use a hidden input, you could just use the button tag instead:
<?php while($row = mysqli_fetch_array($result)) { ?>
<tr>
<td align="center"><?php echo $row['dept_ID']; ?></td>
<td align="center"><?php echo $row['dept_name']; ?></td>
<td>
<button type="submit" name="departmentID" class="buttonsPromptConfirmDeleteDepartment" value="<?php echo $row['dept_ID']; ?>">Delete</button>
</td>
</tr>
<?php } ?>
Of course, in the PHP script that does the form processing, access the POST index like you normally would:
$id = $_POST['departmentID'];
// some processes next to it
Note: Don't forget the <form> tag.
Additional Note: Don't forget to use prepared statements:
$sql = 'DELETE FROM department WHERE dept_ID = ?';
$stmt = $dbc->prepare($sql);
$stmt->bind_param('i', $id);
$stmt->execute();
// some idea, use error checking when necessary
// $dbc->error
Change
id="departmentID"
to
class="departmentID" and
Change
<script>
$(document).ready(function(){
$(".buttonsPromptConfirmDeleteDepartment").click(function(){
var departmentID = $('input#departmentID').val();
alert(departmentID);
});
});
to
<script>
$(document).ready(function(){
$(".buttonsPromptConfirmDeleteDepartment").click(function(){
var departmentID = $(this).next('input.departmentID').val();
alert(departmentID);
});
});
first of all dept_id in while loop and you are using same id for all dept..
another thing you can get dept_id upon button click using jquery.. like this
$('.buttonsPromptConfirmDeleteDepartment').click(function(){
dept_id = $(this).next('input').val();
})

single id alerting same time in a while loop

I am having a table from where i am fetching activities and displaying in a table ...like this
<table width="1000px;" style="border:0px;" >
<tr>
<?php
$sql_activities="select * from tb_activities";
$query_activities=mysql_query($sql_activities);
while($row_activities=mysql_fetch_array($query_activities))
{
?>
<td width="50">
<input type="radio" value="<?php echo $row_activities['activity_name']; ?>" name="activities" onclick="hi() " id="activities" /><?php echo " ".$row_activities["activity_name"]; ?></td>
<?php
}
?>
</tr>
</table>
Now i have applied it in an onlick event of a radio button and the script for the function is:
<script type="text/javascript">
function hi()
{
a = document.getElementById("activities").value;
alert(a);
}
</script>
i want to alert the name of the activity chosen but when i click on any activity, it shows the same. The first activity.ven if i have clicked on any other activity...can anyone help me ??
what you should do is change this:
onclick="hi()"
to this:
onclick="hi(this);
then your function would be:
function hi(who) {
var a = who.value;
alert(a);
}
In PHP side of things change:
<td width="50"><input type="radio" value="<?php echo $row_activities['activity_name']; ?>" name="activities" onclick="hi() " id="activities" /><?php echo " ".$row_activities["activity_name"]; ?></td>
To: ( YOU NEED Unique IDs on Input/ Radio Buttons to be generated dynamically & Sent to JS)
<?php $i = 1; ?>
<td width="50"><input type="radio" value="<?php echo $row_activities['activity_name']; ?>" name="<?php echo $row_activities['activity_name'].$i; ?>" id ="<?php echo $row_activities['activity_name'].$i; ?>" onclick="hi("<?php echo $row_activities['activity_name'].$i; ?> ")" /></td>
<?php $i++; ?>
In Javascript Change to This:
function hi(elementID) {
var value = document.getElementById(elementID).value;
alert(value);
}
Code may have some escape errors, but logically this should give you idea how to do it, Hope that helps.

jQuery
$(document).ready(function ()
{
$('.sub-item p button').click(function ()
{
var buttonID = $(this).attr('id');
alert('table#' + buttonID);
$('table.hidden').hide();
$('table#' + buttonID).show();
});
});
The first code example describes how I generated a list of buttons, with the ID from the sql database. So every button has it's unique ID coming from the fitting database entry.
The second code example describes a table generated from database entries, every table gets a unique ID coming from the fitting database entry.
The third code example should get the ID of the button I click, get the table with the same ID as the button, hide all tables and only show the table with the same ID as the button.
The problem is, that it won't show anyting. It just hides all tables...
Just to let you know, I'm completly new to javascript/jQuery.
ID of an element must be unique(Now you have a table and button with the same id) so use a data-* attribute in the button to store the target element id.
<button type="button" data-target="<? echo $sub["InstrID"] ?>" class="submenu-button"><? echo $sub["InstrName"] ?></button>
then in the click handler
var buttonID = $(this).data('target');
