I am using a pagination script. I got it from a template. It has search option plus show items like 5,10,15,20 and and and prev button. Script is working nicely but when i use ajax and refresh that table part using
$(#tablerefresh).html(data)
then just a table is show with no search options, no next previous options nothing just all rows show.
<script type='text/javascript' src='../../js/plugins/Table/Table.js'></script>
thats the script file. I placed this inside the calling php page but nothings work. I will post the code if you want to see the script code.any suggestions?
In sucess function else part runs when updating occurs:
else
{
// Dropdown start option.
$('select').val(0);
// Clear fields data. (text).
$('form :input[type=text]').attr('value','');
// Password error hide.
$('#userpassword').css("border-color", "#918C8C");
$('#userconfirm').css("border-color", "#918C8C");
$('#usershowdiv').hide();
// Username - Space error show.
$('#userspace').css("border-color", "#918C8C");
$('#usershowdiv3').hide();
// Username - User already exists error show.
$('#userexists').css("border-color", "#918C8C");
$('#usershowdiv4').hide();
// Show ok image.
$('#okicon2').show();
// Hide ok image.
$('#okicon2').delay(8000).fadeOut();
// Show success message.
$('#usersuccess').show();
// Show success message hide after some time.
$('#usersuccess').delay(8000).fadeOut();
// Hide x image.
$('#crossicon2').hide();
// Again Display Table after refresh.
$('#refreshuserlist').html(data);
}
js:
<script type="text/javascript">
$(document).ready(function()
{
// dataTable
if($(".fTable").length > 0)
$(".fTable").dataTable({bSort: true,
"iDisplayLength": 5, "aLengthMenu": [5,10,25,50,100], // can be removed for basic 10 items per page
"aoColumnDefs": [{"bSortable": false,
"aTargets": [ -1 , 0]}]});
// eif dataTable
});
</script>
how i use that:
<table class="table fTable lcnp" cellpadding="0" cellspacing="0" width="100%">
</table>
If your pager and search are dynamically added to page, then in ajax success re-call these functions to apply to new elements, that was replaced in your page:
function createSearchField(){
$('body').append('<div class="search"></div>');
}
In ajax:
$.ajax({
url: 'example.com',
success: function(){ createSearchField(); //Call once more. }
})

I am porting an application to WordPress. It uses a form to select what attributes the customer is looking for in an Adult Family Home via checkboxes and drop-downs. It re-searches the database on each onchange and keyup. Originally I had the application standalone in PHP, but when I migrated it to WordPress I started having issues.
Currently in WP I have the code conditionalized ($DavesWay == 1) to do ajax the normal no-WordPress-way and ($DavesWay == 0) to do it the WordPress-way.
In the non-WordPress-way, the ajax works fine EXCEPT that I get a WP header and menu between the search form and the results-div that Ajax puts the data in. I get no errors from WP or in the JS console. In the WP-way The search form displayed, but nothing happens when I check any of the checkboxes. The JS console displays
POST http://localhost/demo4/wp-admin/admin-ajax.php 400 (Bad Request)
But I don't see any way to tell exactly what it is complaining about. How should I troubleshoot this?
Troubleshooting = Examine the HTML output, lots of echos and exits in PHP code, look at JS console.
function submitPg1(theForm) {
// Used with onChange from "most" form elements, but not on those that change the page
// rather than the select criteria. Such as rowsPerPage, pageNumber etc.
setById("pageNo", "1"); // set inital page
mySubmit();
}
function mySubmit(theForm) { // The actual ajax submit
// DO NOT set page number
jQuery.ajax({ // create an AJAX call...
data: jQuery("#asi_search_form").serialize(), // get the form data
type: jQuery("#asi_search_form").attr("method"), // GET or POST
url: jQuery("#asi_search_form").attr("action"), // the file to call
success: function (response) { // on success..
jQuery("#result").html(response); // update the DIV
}
})
}
function setById(id, value) { // Used to set vales by Id
x = document.getElementById(id).value;
x.value = value;
}
// 1st submit with blank selection
jQuery(document).ready(function () { submitPg1(this.form) });

PHP code:

if( $operation == "submit"){
require("asi_LTCfetchAll.php"); // for each onchange or onkeyup

add_filter( 'the_content', 'asi_tc_admin', '12' ); // Initial page refresh # must be >12

function asi_LTCfetchAll_ajax(){
//echo "<br /> Goto to Submit function"; // DEBUG
require($asi_plugin_dir . "/includes" . '/asi_LTCfetchAll.php');
}
add_action( "wp_ajax_asi_LTCfetchAll_ajax", "asi_LTCfetchAll_ajax" ); // admin users
add_action( "wp_ajax_nopriv_asi_LTCfetchAll_ajax", "asi_LTCfetchAll_ajax" ); // non-logged in users
add_filter( "the_content", "asi_tc_admin", "12" ); // Initial page refresh # must be >12
}
Try changing the JavaScript to the way WordPress recommends it in their documentation:
var data = {
'action': 'my_action',
'whatever': 1234
};
jQuery.post(ajaxurl, data, function(response) {
alert('Got this from the server: ' + response);
});

Also you can use the plugin: https://wordpress.org/plugins/ajax-search-lite/
Hi I am printing the ajax html response to div element and giving radio input option to select the file. after selecting the specific file the another div should show the message. but the ajax html response is not working
Jquery script:
$(document).ready(function()
{
$('#upload').ajaxForm({
beforeSubmit: function() {
$('#Analysis').show();
$('#Content_column').hide();
$('#file_list').show();
$('#trait').show();
$('#trait').html('Submitting...');
},
success: function(data) {
var $out = $('#file_list');
$out.html('       File list:');
$out.append('<div id="list">');
$('#list').html(data);
$out.append('</div>');
}
});
});
The output of this script is
<ul class="php-file-tree"><li class="pft-directory">Genotypic<ul><input id="Penotypic" type="radio" name="uploads/Genotypic/" value="uploads/Genotypic/jquery.txt" />jquery.txt<br><input id="Penotypic" type="radio" name="uploads/Genotypic/" value="uploads/Genotypic/marker.csv" />marker.csv<br></ul></li><li class="pft-directory">Other</li><li class="pft-directory">Penotypic<ul><input id="Penotypic" type="radio" name="uploads/Penotypic/" value="uploads/Penotypic/namPheno.csv" />namPheno.csv<br><input id="Penotypic" type="radio" name="uploads/Penotypic/" value="uploads/Penotypic/perl.pl" />perl.pl<br></ul></li></ul>
Jquery script:
$('#Penotypic').click(function() {
var $out1 = $('#trait');
$('#trait').show();
$out1.append('Submitted...');
});
this is not showing anything in the div trait. may be the html response is loading as a tesxt so the #Penotypic is not recognised. please help me to fix this.
Thanku
You have many inputs of id="Penotypic". Make every id unique or use classes as function trigger.
I wouldn't use "/" in the name attribute. See: http://www.w3.org/TR/html401/types.html#type-name
Then try if your ajax script does work. If it doesn't work, try if it works from static page (don't use your first jQuery script, but it's output as a static form). You probably need to bind your event trigger. Use jQuery's on().
I have a Razor/ASP/MVC3 web application with a form and a Submit button, which results in some action on the server and then posts back to the form. There is often some delay, and it's important that users know they should wait for it to complete and confirm before closing the page or doing other things on the site, because it seems users are doing that and sometimes their work has not been processed when they assume it has.
So, I added a "Saving, Please Wait..." spinner in a hidden Div that becomes visible when they press the Submit button, which works very nicely, but I haven't been able to find a way to get the Div re-hidden when the action is complete.
My spinner Div is:
<div id="hahuloading" runat="server">
<div id="hahuloadingcontent">
<p id="hahuloadingspinner">
Saving, Please Wait...<br />
<img src="../../Content/Images/progSpin.gif" />
</p>
</div>
</div>
Its CSS is:
#hahuloading
{
display:none;
background:rgba(255,255,255,0.8);
z-index:1000;
}
I get the "please wait" spinner to appear in a JS method for the visible button, which calls the actual submit button like this:
$(document).ready(function () {
$("#submitVisibleButton").click(function () {
$(this).prop('disabled', true);
$("#myUserMessage").html("Saving...");
$("#myUserMessage").show();
$("#hahuloading").show();
document.getElementById("submitHiddenButton").click();
});
});
And my view model code gets called, does things, and returns a string which sets the usermessage content which shows up fine, but when I tried doing some code in examples I saw such as:
// Re-hide the spinner:
Response.write (hahuloading.Attributes.Add("style", "visibility:hiddden"));
It tells me "hahuloading does not exist in the current context".
Is there some way I am supposed to define a variable in the view model which will correspond to the Div in a way that I can set its visibility back from the server's action handler?
Or, can I make the div display conditional on some value, in a way that will work when the page returns from the action?
Or, in any way, could anyone help me figure out how to get my div re-hidden after the server action completes?
Thanks!
Is this done with ajax? I would assume so because the page is not being redirected. Try this:
$(document).ready(function () {
$("#submitVisibleButton").click(function () {
$(this).prop('disabled', true);
$("#myUserMessage").html("Saving...");
$("#myUserMessage").show();
$("#hahuloading").show();
document.getElementById("submitHiddenButton").click();
});
$("#hahuloading").ajaxStop(function () {
$(this).hide();
});
});
As an aside, you no longer need runat=server.
I have some results on the page (firts 10), then with a "load more result" button, I send the "id" of the last report to a PHP page.
I'v read here that I have to use .on (because .live is depreciated) so click event on new elements added to the DOM (through AJAX) can work.
My question is ... can I display somehow the content that came through AJAX on a div that was not on the initial DOM ?
$("#jokesWrap").on('click', 'a.share', function(event) {
var joke_id = $(this).attr('name');
var msgbox = $("#success[name='" + joke_id + "']");
$("#post-to-wall[name='" + joke_id + "']").hide();
msgbox.html('<img src="includes/images/load.gif"> Loading...');
$.ajax(
{
type: "POST",
url: "includes/php/ajax.php",
data: "joke_id=" + joke_id,
success: function(msg)
{
if(msg == 'OK')
{
msgbox.html('<img src="includes/images/success.png" /> DONE!');
}
} // function(msg)
}); // ajax
event.preventDefault(); });
This is the HTML part:
<div id="jokesWrap">
<div class="joke" id="1">
<p class="txt">
some text
</p>
<div class="joke-options-bar">
Post to wall
<span id="success" name="1" class="share floatL"></span>
<br class="floatClear" />
</div>
</div>
// the above area comes through loop from the ajax call
PS: Everything is ok: the ajax call (The tetxt is posted to the wall) the #post-to-wall is hidden. The "loding..." and the success message it's not shown.
PS2: the "Loading..." text and success message it's shown when I click on link that was on the DOM before the AJAX call ( because the #success was there)
Any help it's apprecied!
As long as the element exists in the DOM when the success callback of the AJAX is executed, you can use jQuery to select and manipulate it in the same way as you would an element that did exist in the DOM when the page was initially loaded. Or you can use jQuery to create the element as part of the success callback, manipulate it using the response from the AJAX request, then append your newly created element to the DOM in the required position. Something like so:
var div = $('<div/>').attr('id', 'new-div-id').html(data);
$('body').append(div);
That creates a new div, gives it an id of new-div-id, then sets its innerHTML to be whatever data was (assuming data is the name of the variable that contains the response text from the AJAX), then finally appends it as a new child of the <body> tag of the page.
Looking at what seem to be edits to the question: Element IDs (specified with the id attribute) have to be unique throughout the entire document; that includes elements added later as part of an AJAX callback. You can't have multiple elements with an id of success - make them unique by doing away with the name attribute, and adding the value to the end of the id instead, so you'd have success1, success2, etc as your IDs.
Add it to the DOM before writing to it?
Could any one give an example, how to use Jquery in Controller Page. MVC3 -ASP.NET(How To put various tags like )
I want to show a simple alert before rendering a view in Controller.
Thank you.
Hari Gillala
Normally scripts are part of the views. Controllers shouldn't be tied to javascript. So inside a view you use the <script> tag where you put javascript. So for example if you wanted to show an alert just before rendering a view you could put the following in the <head> section of this view:
<script type="text/javascript">
alert('simple alert');
</script>
As far as jQuery is concerned, it usually is used to manipulate the DOM so you would wrap all DOM manipulation functions in a document.ready (unless you include this script tag at the end, just before closing the <body>):
<script type="text/javascript">
$(function() {
// ... put your jQuery code here
});
</script>
If you are talking about rendering partial views with AJAX that's another matter. You could have a link on some page that is pointing to a controller action:
#Html.ActionLink("click me", "someAction", null, new { id = "mylink" })
and a div container somewhere on the page:
<div id="result"></div>
Now you could unobtrusively AJAXify this link and inject the resulting HTML into the div:
$(function() {
$('#mylink').click(function() {
$('#result').load(this.href, function() {
alert('AJAX request finished => displaying results in the div');
});
return false;
});
});
