In my application listView('refresh') doesn't work. Here is my code
I create listView dynamically
var str = "<ul data-role='listview' data-inset='true' id='mylist'>";
for(var i = 0; i<data.length; i++ ){
str += "<li>"+data[i].note.text+"</li>";
}
str += "</ul>"
$('#content').append(str);
function addnote(){
var note_text = $('#note_text').val();
var note_lat = $('#lat').val();
var note_lng = $('#lng').val();
$.ajax({
type: "POST",
beforeSend: function (jqXHR) {
jqXHR.setRequestHeader(KEY1, _key1);
jqXHR.setRequestHeader(KEY2, _key2);
},
url:SERVER_URL+"api/addNotes/",
data: {type: 'text',note_text: note_text, note_lat: note_lat , note_lng: note_lng},
success: function(data, textStatus, jqXHR) {
if (data.status == "ok"){
$.mobile.changePage("file:///android_asset/www/index.html?"+_key1+"|"+_key2+"|");
}
else{
alert("Something wrong");
}
},
error: function(jqXHR, textStatus, errorThrown) {
alert("Error=" + errorThrown);
},
complete: function() {
$('#mylist').listview('refresh');
}
});
}
I read many reports and forums there said I have to call listview('refresh') in ajax's complete function. But in my code it doesn't work, could anyone tell me what is the problem here?
Refresh is for when you are adding elements to an existing, enhanced listview. If you are creating the entire listview dynamically you need to trigger a "create" on the parent div.
So if you had <div id="container><ul></ul></div>, you would need to call $("#container").trigger("create").
You probably want to see your data after adding some values. If you want to do this listview.refresh doesn't help you after adding some values you have to call you data again, i.e you have to call getNote() again.
I think it helps.
Try this for you complete function instead
complete: function() {
$('#mylist').listview();
}
As someone else mentions the refresh method is for when you are adding listitems to a listview that JQM has already created.
First of all , You must understand how does the refresh work, it will just refresh the listview's css when you add a new LI so that the new LI will have a right css,
function createItem(tx,results){
var len = results.rows.length;
console.log("lisitem len "+len);
for(var i = 0;i<len;i++){
var content = results.rows.item(i).content;
var id = results.rows.item(i).id;
var string = '<li>'+content+' ['+results.rows.item(i).date+']</li>';
$("#all_list").append(string);
};
freshList("all_list");
}
freshList("all_list"); it will refresh the listview ,if you don't do it, all of the LI will display like below.
<li> 测试成功 [2013-10-02]</li>
the LI doesn't have a css description
that's why your ajax operation doesn't work

I'm using autocomplete with materialize and i'm retrieving the data with ajax call, it works fine but when i want to call ajax only after entering caracters(using onkeyup event), the drop down list will not be showing correctly !!!!
Before i forget please help me to show a "NOT FOUND" in the drop down list if no data founded (because my else condition doesn't work). here is my code and thanks a lot in advance :
$(document).ready(function() {
var contents = $('#autocomplete-input')[0];
contents.onkeyup = function (e) {
$.ajax({
type: 'GET',
url: Routing.generate('crm_search_lead', {"search":
$(this).val()}),
success: function (response) {
var contacts = {};
if (true === response.success) {
var result = response.result;
for (var i = 0; i < result.length; i++) {
var lastName = result[i].lastName ?
result[i].lastName : '';
var firstName = result[i].firstName ?
result[i].firstName : '';
contacts[lastName + " " + firstName] = null;
}
$('input.autocomplete').autocomplete({
data: contacts,
minLength: 2,
});
} else {
$('input.autocomplete').autocomplete({
data: {
"NOT FOUND": null
}
});
}
}
});
}
});
Hi people :) i resolve it by changing onkeyup() with focus() and it's totally logical because with onkeyup() the droplist will appear and disappear very quickly on every key entered.
After two days of fruitless research, I decided to join the community. I hope to get a solution. I develop a plug-in that, among other things, must implement the upload of documents. this should be done using ajax technology. the problem is that the request is approved, but admin_ajax.php reacts like no action was taken. Outside of wp this piece of code works fine, as it was thought out. The problems come with installing this code in wp. Below is my code
PHP. This code in the main class that will call from main modul of plugin
class main{
//other activation methods
private function register_scripts(){
add_action('wp_enqueue_scripts', array($this,'re_add_script'));
}
public function re_add_script() {
wp_enqueue_script('re_upload',plugins_url('re'.'/js/re_upload.js'),array('jquery'));
wp_localize_script('re_upload',"re_ajax",array(
'ajaxurl'=>admin_url("admin-ajax.php")));
add_action( 'wp_ajax_upload', 'processingUpload');
}
}//end of class
//callback function
function processingUpload(){
$clsUpload = new UploadsDocs();
$clsUpload->setRequestedData($_FILES,$_POST['doc_id']);
$clsUpload->checkUploadsFiles();
$clsUpload->outputFilesList();
wp_die();
}
jQuery 're_upload.js'
jQuery(document).ready(function (e) {
jQuery('#bt_upload').on('click', function () {
var toUpload=getFileListToUpload();
var form_data = new FormData();
var ins = input.files.length;
for (var x = 0; x < ins; x++) {
if (isFileToUpload(input.files[x],toUpload)){
form_data.append("files[]", input.files[x]);
}
}
form_data.append("doc_id", jQuery('#doc_id')[0].value);
var data_to_sent={
action: 'upload',
datas: form_data
};

for(var i=0; i<files_toUpload.length;i++){
if (input_file.name==files_toUpload[i]){
res=true;
break;
}
}
return res;
}
The problem is
add_action( 'wp_ajax_upload', 'processingUpload');
is not called.
The upload is done in two separate invocations of the server. The first invocation displays the upload page to the user. The second invocation processes the AJAX request. Your call to
add_action( 'wp_ajax_upload', 'processingUpload');
is done in the first invocation where it is not needed but not in the second invocation where it is needed.
Please read https://codex.wordpress.org/AJAX_in_Plugins. (Observe carefully how the call to 'add_action( 'wp_ajax_...', ...) is done.) Further, you need to read about nonces.
Try to append action to your ajax url like:
url: re_ajax.ajaxurl?action=upload
and
data: form_data
or pass it to form_data like:
form_data.append('action', 'upload')
I am using the following code to sort the rows of a table based on Ids. I am using Dragula for drag and drop functionality. The Sorted Ids is presented in the variable sortedIDs. The alert present within if(sortedIDs) is showing an alert, but no request is being sent using AJAX.
var container = document.getElementById('tb');
var rows = container.children;
var nodeListForEach = function (array, callback, scope) {
for (var i = 0; i < array.length; i++) {
callback.call(scope, i, array[i]);
}
};
var sortableTable = dragula([container]);
var pingu='';
sortableTable.on('dragend', function() {
nodeListForEach(rows, function (index, row) {
//alert(row.id);
pingu=pingu+','+row.id;
//alert(pingu);
// row.lastElementChild.textContent = index + 1;
// row.dataset.rowPosition = index + 1;
});
var sortedIDs=pingu;
pingu='';
// alert (sortedIDs);
if (sortedIDs) {
alert(sortedIDs);
$.ajax({
type: 'GET',
url: '<?php echo $site_url . 'index.php/API/p2376ghDSPOLWYBdhBT'?>',
data: 'lmqSPOEhyVt87H6tBYSfdreg=' + sortedIDs + '&hjhqweuty87685gh87GCfsc6HF=' + sbds98JWUDGHKJ98yujg,
success: function (tata) {
alert (tata);
if (tata == '1') {
$("#success").show();
$('#success').delay(2000).fadeOut('slow');
} else {
$("#failure").show();
$('#failure').delay(5000).fadeOut('slow');
}
}
});
} else {
//$('#ms').html('<option value="">Select Q level first</option>');
}
});
And when i am adding
error : function(jqXHR, textStatus, errorThrown){
}
for showing AJAX error, it starts throwing the alert too.
Any sort of help would be deeply appreciated.
Thanks
I solved the problem. I forgot to retrieve the value of an attribute and send it to the API.
var sbds98JWUDGHKJ98yujg = $('#p2JMopns3hfBubNNHJeer').val();
I have set up a test site using masonry and am using isotope for sorting.
I have also set up a button at the bottom that the user can click to ajax load more posts.
I have the ajax loading working properly, but when the new posts get appended to the bottom of the container the first four posts at the top all shift out of place. If I keep clicking 'load more' all subsequent posts that load load perfectly and nothing else shifts. It seems to be only the first four posts, on the first ajax load.
Anyone know why this is happening?? It's driving me crazy
Ajax Load File
// ajaxLoop.js
jQuery(function($){
var page = 1;
var loading = true;
var $window = $(window);
var $ajaxLoadMoreButton = $("body.blog .ajaxLoadMoreButton");
var $content = $("body.blog #container");
var load_posts = function(){
$.ajax({
type : "GET",
data : {numPosts : 1, pageNumber: page},
dataType : "html",
url : "wp-content/themes/twentytwelve/loopHandler.php",
beforeSend : function() {
if(page !=1) {
}
},
success : function(data){
$data = $(data);
if($data.length){
$data.hide();
$content.append($data).masonry('reload');
$data.fadeIn(500, function(){
$("#temp_load").remove();
loading = false;
});
} else {
$("#temp_load").remove();
}
},
error : function(jqXHR, textStatus, errorThrown) {
$("#temp_load").remove();
alert(jqXHR + " :: " + textStatus + " :: " + errorThrown);
}
});
}
$ajaxLoadMoreButton.click(function() {
loading = true;
page++;
load_posts();
});
});
To anyone else having this issue, after digging for hours through documentation and asking for help on SO and other sites, I have resolved the issue. The issue apparently lies within -webkit browsers and the transform property that is placed on masonry elements after appending new ones.
I used this as a reference:
http://isotope.metafizzy.co/docs/help.html#disabling_transforms
and then I used this code to disable all transforms on elements:
$("#container").isotope({
itemSelector : ".brick",
transformsEnabled: false, // disables all transform properties
getSortData : {
name : function () {
$tag = $("#container").find("a[rel=tag]").text();
}
}
});
I posted this question AJAX URL update as I thought the problem with my code was with AJAX but I think this could be an issue with HighStocks.
I have an external .js file with these functions:
//uses AJAX call to retrieve data and then creates the chart with the data
function createChart(ticker) {
$.ajax({
type: 'post',
url: 'http://...' + ticker + '....com',
success: function (data, status) {
//chart is rendered in here
}
//gets the user inputted ticker symbol from a HTML input box
// and passes to chart function
function getTicker() {
var ticker = document.getElementById('userInput').value;
createChart(ticker);
}
My HTML file just has a simple form with an input box and a button that when clicked calls the getTicker function. For some reason the chart is not being created and the AJAX call doesnt seem to work.
Is this something with HighStocks maybe? Any suggestions would be appreciated.
UPDATE Thank you for the suggestions, I have attempted to use JSONP but the chart still does not load. Can anybody see what I am doing wrong?
var closePrices = new Array();
var dateArray = new Array();
var timeStampArray = new Array();
var timeClose = new Array();
function jsonCallback(data, ticker) {
console.log( data );
//Put all the closing prices into an array and convert to floats
for(var i=0; i < data.query.results.quote.length; i++)
{
closePrices[i] = parseFloat( data.query.results.quote[i].Close );
}
//displays the values in the closePrices array
console.log( closePrices );
//Put all the dates into an array
for(var i=0; i < data.query.results.quote.length; i++)
{
dateArray[i] = data.query.results.quote[i].date;
}
//Convert all the dates into JS Timestamps
for(var i=0; i < dateArray.length; i++)
{
timeStampArray[i] = new Date( dateArray[i] ).getTime();
}
for(var i=0; i<data.query.results.quote.length; i++)
{
timeClose.push( [timeStampArray[i], closePrices[i]] );
}
timeClose = timeClose.reverse();
console.log ( timeClose );
//displays the dateArray
console.log( dateArray );
console.log( timeStampArray );
// Create the chart
$('#container').highcharts('StockChart', {
rangeSelector : {
selected : 1
},
title : {
text : ticker + ' Stock Price'
},
series : [{
name : ticker,
data: timeClose,
tooltip: {
valueDecimals: 2
}
}]
});
}
function createChart() {
var url = 'http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.historicaldata%20where%20symbol%20%3D%20%22' + ticker +'%22%20and%20startDate%20%3D%20%222013-01-01%22%20and%20endDate%20%3D%20%222013-02-25%22&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=?';
//Ajax call retrieves the data from Yahoo! Finance API
$.ajax( url, {
dataType: "jsonp",
success: function(data, status){
console.log(status);
jsonCallback(data, ticker);
},
error: function( jqXHR, status, error ) {
console.log( 'Error: ' + error );
}
});
}
//Function to get ticker symbol from input box.
function getTicker() {
var ticker = document.getElementById('userInput').value;
createChart(ticker);
}
Thanks to Jeffrey Blake and Pawel Fus for your suggestions. Using JSONP I was able to get my program functioning correctly :)
