$("input").keyup(function()
{
alert($("#val").val());
});
</script>
NOTE I will try to get text-box value when key-up event fire but always first text box value display how i will get text-box value
which key-up event fire
Use this
$("input").keyup(function()
{
alert($(this).val());
})
By the way, the id attribute must be unique within the HTML document, see http://www.w3schools.com/tags/att_global_id.asp
use alert($(this).val()); instead of alert($("#val").val());

<?php
while($query=mysql_fetch_assoc($select)){
?>
<tr><td><input type="checkbox" name="checkBoxMail" id="checkBoxMail"
value="<?php echo $query['id']; ?>"
userid="<?php echo $query['suserid']; ?>"></td>
</tr>
<?php
}
?>
This code created multiple checkbox in view page. First check only return value after that next check box click is not working
$('#checkBoxMail').click(function(){
alert("alert");
});
There would be multiple checkboxes with same id which is wrong. Try with class.
<input type="checkbox" name="checkBoxMail" class="checkBoxMail"
value="<?php echo $query['id']; ?>"
userid="<?php echo $query['suserid']; ?>">
And
$('.checkBoxMail').click(function(){
alert("alert");
});
And if you want to access the value or attribute then simple do -
$(this).val();
$(this).attr('userid');
Three examples of how you can do this by ID:
Remember if you're creating multiple checkbox fields don't set the same ID, make a different ID for each one or you can select the checkbox by class by changing the # to . as you can use the classname multiple times.
The ID has to be unique
$(document).ready(function()
{
// By ID - ID has to be unique
$('#checkBoxMail').on("click", function()
{
alert("alert");
});
$('#checkBoxMail2').click(function()
{
alert("alert2");
});
$(document).on("click", "#checkBoxMail3", function()
{
alert("alert3");
});
// By classname
$('.checkBoxMail5').on("click", function()
{
alert("alert");
});
$('.checkBoxMail5').click(function()
{
alert("alert2");
});
$(document).on("click", ".checkBoxMail5", function()
{
alert("alert3");
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
Divs with unique ID
<hr>
<div id="checkBoxMail">CLICK ME</div>
<div id="checkBoxMail2">CLICK ME</div>
<div id="checkBoxMail3">CLICK ME</div>
<br>
Div with classname
<hr>
<div class="checkBoxMail5">CLICK ME</div>
You are using same id for all checkbox creted, either use unique id for each checkbox or use class. See below code, where i have used class
<?php
while($query=mysql_fetch_assoc($select)){
?>
<tr><td><input type="checkbox" name="checkBoxMail" class="checkBoxMail"
value="<?php echo $query['id']; ?>"
userid="<?php echo $query['suserid']; ?>"></td>
</tr>
<?php
}
?>
jQuery:
$(document).on('click','.checkBoxMail', function(){
alert("alert");
});
Give class to all and Read about delegated event handlers , that would help: http://api.jquery.com/on/
$(document).on("click",".classname",function(event){
alert("hi");
});
Delegated events have the advantage that they can process events from
descendant elements that are added to the document at a later time. By
picking an element that is guaranteed to be present at the time the
delegated event handler is attached, you can use delegated events to
avoid the need to frequently attach and remove event handlers
$(document).ready(function () {
$('#checkBoxMail').click(function () {
alert("click event fired")});
});
<input type="checkbox" name="checkBoxMail" id="checkBoxMail" />
$('#checkBoxMail').is(':checked'){
alert("alert");
});
Try this. Enjoy!
I am working in wordpress and I have created a custom plugin.In which I have get multiple data from the database and my code is like this.
<?php
foreach($result as $res)
{
?>
<input type="hidden" class="status" value="<?php echo $res->review_status; ?>" />
<button class="aprove" value="<?php echo $res->review_id; ?>">Aprove</button>
<?php
}
?>
Now, I want to get hidden field value in jQuery. My jQuery code is like this:
jQuery(".aprove").click(function(){
var status = jQuery('.status').val();
alert(status);
});
When I click on button then it shows only first value of hidden field. For instance, the fist hidden value is 1 and second value is 0 then it display only fist value 1 for both button. So what shold I have to do to get different hidden value?
Try :
jQuery(".aprove").click(function(){
jQuery('.status').each(function(){
var status = jQuery(this).val();
alert(status);
});
});
.each will loop through all the classes and it will give alert every value of it.

Here is your answer. for each button the value taken would be from the input element before the button element
jQuery(".aprove").click(function(){
var status = jQuery(this).prev('.status').val();
alert(status);
});
var status = jQuery('.status').val();
alert(status);
this will get the value of element first found on page and will return the result,
if you want all the input values use
jquery each() - https://api.jquery.com/jquery.each/
jQuery('.status').each(function(){
alert($(this).val());
});
// this will give you all the values you want, one by one
you can use .map like this to get what you want:
$(document).ready(function(){
var status=[]
jQuery(".aprove").click(function(){
status = $(".status").map(function() {
return $(this).val();
}).get();
alert(status);//array of values
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="hidden" class="status" value="0" />
<input type="hidden" class="status" value="1" />
<button class="aprove" value="">Aprove</button>
I have this script thats send a post via jquery.form addon:
$(document).ready(function() {
$('#submit_btn').on('click', function(e) {
$("#preview").html('');
$("#preview").html('<img src="loader.gif" alt="Uploading...."/>');
$("#imageform").ajaxForm({
target: '#preview',
success: afterSuccess //call function after
});
});
});
function afterSuccess()
{
$('#imageform').resetForm();
$('.ImgStatus').appendTo('.img');
}
and gets a html respond.
<div id="<?php echo $RandNumber; ?>" class="ImgStatus">
<input id="<?php echo $RandNumber; ?>" type="checkbox" name="<?php echo $RandNumber; ?>" />
<img src='upload/<?php echo $actual_image_name; ?>' class='preview'>
</div>
And what I'm trying to do is to remove the div that corresponds to the checkbox ID, when the delete button is clicked. And also to send a $_POST to a php page with the checked divs. Until now I have something like this but When I press the button its not removing the element...
$("#clickme").click(function(e){
var selected = $(".img input:checked").map(function(i,el){return el.name;}).get();
$(selected).remove();
});
jsfiddle.net/aHr6v/3
You can simply select the parent of the selected input field (the div), and remove it like this:
$("#clickme").click(function(e){
var selected = $(".img input:checked").parent();
$(selected).remove();
});
Here's a working example: http://jsfiddle.net/aHr6v/5/
check this: http://jsfiddle.net/aHr6v/6/
Based on what you said in your comment, I added the following line which search the div by its id and remove it
$("div#"+selected).remove();
I'd suggest:
$("#clickme").click(function (e) {
$('div.img input:checked').closest('div').remove();
});
JS Fiddle demo.
This looks at all inputs that are checked, finds the closest parent ancestor that's a div and then removes that/those elements from the DOM.
References:
closest().
remove().
selected is an array. What you want to do is pass one or more elements of that array as a selector:
$.each(selector, function(){
$('#' + this).remove();
})
Just change
$(selected).remove();
To
$('#'+selected).remove();
Edit: Or To (to remove all selected divs)
$.each(selected, function(){
$('#' + this).remove();
});
Hi i'm using php and jquery. I have create dinamically a list of a div like that
<div class="divclass" id="<?php echo $i-1;?>">
<a href=" <?php echo $this->url(array('controller'=>'controller name','action'=>'action name'));?>">
<span>Date: </span>
</a>
</div>
My javasctipt script is, i pick the name of the id clicked, i set the hidden parameter to the name of the id and i want to submit the form
<script type="text/javascript">
$(document).ready(function() {
$('.divclass').click(function(){
var idarray = $(this).attr("id");
document.getElementById('testo').value=idarray;
document.forms["prova"].submit();
});
});
The form is:
<form id="prova" method="post" action="<?php echo Zend_Controller_Front::getInstance()->getBaseUrl().'/controller-name/action-name';?>">
<input type="hidden" value="" id="testo">
</form>
</script>
But in the next page i don't have the post parameter.
You need to give name attribute to #testo and then try this:
e.g
<input type="hidden" value="" id="testo" name="testo">
Your form is within <script> tag, Place it outside of <script> tag.
and write following code within DOM ready like follwing:
<script type="text/javascript">
$(function() {
// after DOM ready
$('.divclass').click(function(){
var idarray = $(this).attr("id"); // or this.id do the same thing
$('#testo').val(idarray); // set value to testo
$("form#prova").submit(); // submit the form
});
});
</script>
I'm using a form plugin / addon where I don't have control over how the form is generated.
The form generates HTML which looks like this:
<form>
<label>First Name</label><input name="Question25" type="text" value="" />
<input class="formBlockSubmitButton" name="add" type="submit" value="Submit" />
</form>
I would like to prefill some of the form values but I can't write, say
<input name="Question25" type="text" value="<?php echo $my_value; ?>" />
Because the form addon generates that HTML. I can write PHP or Javascript before this block, is there a way to search for an input with a name of "Question25" and then prefill it when the block comes up?
You could use jQuery and the .val() method:
<script type="text/javascript">
$(function() {
$('input[name="Question25"]').val('some value');
});
</script>
and if the value must come from the server:
<script type="text/javascript">
$(function() {
var obj = <?php echo json_encode(array('value' => $my_value)); ?>;
$('input[name="Question25"]').val(obj.value);
});
</script>
You can emit all the values you'd like to search as an array of fieldname/values, and then emit a function that tries to map those values to those fields.
<script type="text/javascript">
var values = [{fieldName:'Question25', value:'MyValue'}]; // iterate through your values in PHP and generate the {fieldName:'value',value:'value'} object
$(function() {
$.each(values, function(index, item) {
$('input[name=' + item.fieldName + ']').val(item.value);
});
});
</script>
var value='<?php echo $my_value; ?>'
$("input:text[name='Question25']").val(value);
use something like this
Use Javascript. With jQuery, you could do something along the lines of:
$("input[name=Question25]").val(my_value);
You can then insert PHP vairables into the Javascript with echo, load them with AJAX, or whatever you need.
