Hi i am basically new to Ajax and having a tough time writing it..
I want to assign src value to Iframe which is fetched from the database
Table is HobbyMasters
HobbyName
HobbyUrl
I write a function and fetch the url from the table now when i click on Hobbyname which is displayed as link i want that url to be loaded inside the Iframe.
Initially i wrote a javascript:
<script type="text/javascript">
$(document).ready(function () {
$('a').click(function (e) {
e.preventDefault();
$('iframe').attr('src', "Dancing");
});
}); </script>
But here the src is static and through javascript i am not able to assign fetched value from databse to src attribute
So thought of writing Ajax..
I have tried something but it is incomplete.Please Help me with this:
<script type="text/javascript">
$(document).ready(function () {
$('a').click(function (e) {
e.preventDefault();
var filename = $(this).text();
var Hobbyurl = '#Url.Action("FetchUrlByHobbyName")';
$.ajax({
type: "POST",
url: Hobbyurl ,
data: { data: filename },
success: function (returndata) {
Here i want to assign the fetched src from function FetchUrlByHobbyName to Iframe src
$('iframe').attr('src', filename);
}
});
});
Function inside the Controller:
[HttpPost]
public ActionResult FetchUrlByHobbyName(string Hobbyurl)
{
HobbyMasters hobbymaster = new HobbyHomeService().FetchHobbyMasterByHobbyName(Hobbyurl);
string url=hobbymaster.InformationUrl;
if (HttpContext.Request.IsAjaxRequest())
return Json(new{src=url});
return View();
}
If #Url.Action("FetchUrlByHobbyName") returns the url of the hobby , you can do
<script type="text/javascript">
$(document).ready(function () {
$('a').click(function (e) {
e.preventDefault();
var filename = $(this).text();
var Hobbyurl = '#Url.Action("FetchUrlByHobbyName")';
$.ajax({
type: "POST",
url: Hobbyurl ,
data: { data: filename },
success: function (returndata) {
Here i want to assign the fetched src from function FetchUrlByHobbyName to Iframe src
$('iframe').attr('src', returndata);
}
});
});
The best method would be to return the data associated with json and get the url from the json object
success: function (returndata) {
jsonObj = jQuery.parseJSON( returndata)
$('iframe').attr('src', jsonObj.url);
}

I want simply to send an element via a event so that to catch it as a parameter in a servlet, but NOT from the regular Form's button.
I would appreciate a suggestion.
<script>
$(document).ready(function () {
$('#idSelect').change(function () {
$.post("SelectChange",$('#idSelect'), function () {
});
});
});
</script>
Like so, capture the value on change, then send it to the php file.
Access in the PHP with $_POST['select_data'];
$(document).ready(function () {
$('#idSelect').change(function () {
var select_value = $("#idSelect").val();
$.ajax({
type: "POST",
url: '/var/www/file-receiving-data.php',
data: ({ select_data: select_value}),
success: function(data) {
console.log("successfully sent to php file");
}
});
});
});
So, with the 1st answer (without which no chance to get it), til fix the other simpler permanently, the working solution is:
In servlet:
String val = request.getParameter("val");
In jsp, append the value to the url, as follows:
<script>
$(document).ready(function () {
$('#idSelect').change(function () {
var xhttp = new XMLHttpRequest();
xhttp.open("POST", "SelectChange?val="+$('#idSelect').val(), true);
xhttp.setRequestHeader("String", "application/x-www-form-urlencoded");
alert("send de POST: "+$('#idSelect').val());
xhttp.send();
});
});
</script>
I have one html page which contains a jquery function.
<script>
function loadCustomers() {
$.ajax({
type: 'GET',
url: 'http://localhost:8080/cache/getCustomers',
dataType: 'json',
success: function(data) {
var rows = [];
$.each(data,function(id,value) {
rows.push('<tr><td><a href="clientSiteInfo.html?client=">'+id+'</td><td>'+value+'</td></tr>');
});
$('table').append(rows.join(''));
}
});
};
window.onload = loadCustomers;
</script>
I have linked another html page for each row. When each rows populated, the id values has to be passed to the clientSiteInfo.html page.
In the clientSiteInfo.html page i have another jquery function similar to above.
<script>
function loadSites() {
$.ajax({
type: 'GET',
url: 'http://localhost:8080/cache/getSite?clientName='+${param.client},
dataType: 'json',
success: function(data) {
var rows = [];
$.each(data,function(id,value) {
rows.push('<tr><td>'+id+'</td><td>'+value.machine+'</td><td>'+value.state+'</td></tr>');
});
$('table').append(rows.join(''));
}
});
};
window.onload = loadSites;
</script>
in the GET url I try to read client parameter. But it is not passing from my initial page.
What Im doing wrong here? I look for simple solution
jQuery doesn't have a native way to read the url parameters. However, javascript works just fine:
function getParameterByName(name) {
const match = RegExp(`[?&]${name}=([^&]*)`).exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' ') );
}
In your code you would just call it as getParameterByName('client')
I want to fetch data from div tag which set contenteditable=true
I have used autosuggestion in that..Data is successfully fetched but when I write item which is written in autosuggestion field then it wont be fetched because it add HTML tag and it wont save into database
My code
if data is changed:
var timeoutID;
$('[contenteditable]').bind('DOMCharacterDataModified', function () {
clearTimeout(timeoutID);
$that = $(this);
timeoutID = setTimeout(function () {
$that.trigger('change')
}, 50)
});
$('[contentEditable]').bind('change', function () {
getTextChangeContent();
});
UPDATE
function getTextChangeContent() {
var ma = document.getElementById('myAudio');
var remove = ma.src.slice(0, -4);
var path = remove.substring(remove.lastIndexOf("/") + 1);
var newPath = path.concat('.wav');
var text_id = document.getElementById('textbox');
var textdata = text_id.innerHTML;
$.ajax(
{
type: "POST",
url: '#Url.Action("getChangeContent")',
dataType: "json",
mtype: "post",
data: { arg: varid, content: textdata, path: newPath },
async: true,
success: function (data) {
alert(data + " DATA");
}
});
}
when I changed data and use autosuggestion then it will show data as
The door is blacl <span class="atwho-inserted">[[Ceilings]]</span>
How to ignore html tag and take only values of that?
Plz suggest me
Retrieve innerText rather than innerHTML in order to ignore the HTML content. If you want only the content inside the html tag with class .atwho-inserted, then retrieve only that content.
var textdata = text_id.innerText;
If I have a script like below that's ran to load a table with data injected into it from an external PHP file on to the page.
<script>
$(document).ready(function(){
var response = '';
$.ajax({ type: "GET",
url: "Records.php",
success : function(text)
{
response = text;
}
});
alert(response);
});
</script>
I have another script down below where a user can add records to the database.
<script id="sosurce" language="javascript" type="text/javascript">
$("#newitemadd").click(function(){
$('#New').modal('show');
$("#insertResults").click(function(){
var getname = $('#getname').val();
var getquant = $('#getquant').val();
var getprice = $('#getprice').val();
var getdesc = $('#getdesc').val();
$.ajax({
url: 'api2.php',
data: "name="+getname+"&quantity="+getquant+"&price="+getprice+"&description="+getdesc,
success: function(data)
{ $('#New').modal('hide');
$("#success").html(data);
$('#success').slideDown().delay(3000).slideUp().reload
},
error: function() {
$("#failure").alert('show');
}
});
});
});
</script>
It works fully as intended but, how can I get the first script to Re-Run so the table that's inserted onto the page is refreshed to show the new results that were just added?
you can do like this .
<script>
var renderTable = function() {
var response = '';
$.ajax({ type: "GET",
url: "Records.php",
success : function(text)
{
response = text;
}
});
alert(response);
}
// Call function onload
jQuery(function($){
renderTable();
$(".refreshBtn").click(function(){
renderTable();
})
});
</script>
Move first code into an function like
<script>
$(document).ready(LoadData);
function LoadData() {
var response = '';
$.ajax({
type: "GET",
url: "Records.php",
success : function(text) {
response = text;
}
});
alert(response);
};
</script>
And call this function from other function, example does it on success
<script id="sosurce" language="javascript" type="text/javascript">
$("#newitemadd").click(function() {
$('#New').modal('show');
$("#insertResults").click(function() {
var getname = $('#getname').val(),
getquant = $('#getquant').val(),
getprice = $('#getprice').val(),
getdesc = $('#getdesc').val();
$.ajax({
url: 'api2.php',
data:
"name="+getname+"&quantity="+getquant+"&price="+getprice+"&description="+getdesc,
success: function(data) {
$('#New').modal('hide');
$("#success").html(data);
$('#success').slideDown().delay(3000).slideUp().reload
// Call load data again to refresh the table
LoadData();
},
error: function() {
$("#failure").alert('show');
}
});
});
});
</script>
I have a script like this.
The jQuery ajax loads all my files with no issues.
The ajax_load_books.php file have lot of css and js(inline edit, sliders etc.) files in it.
The problem is:
How to load all the files before the success function so that the user can see the loader_div message untill all the files are loaded.
In other words - Load all the js/css files and proceed with the success function.
Even I have checked with .load() function. Could someone redefine the below code .
<script type="text/javascript">
$(document).ready(function () {
$(".form-control").change(function () {
var id = $(this).val();
var dataString = 'id=' + id;
$.ajax({
type: "POST",
url: "ajax_load_books.php",
data: dataString,
cache: false,
beforeSend: function () {
$("#loader_div").show();
},
success: function (html) {
$("#loader_div").hide();
$("#txtHint").html(html);
}
});
});
});
</script>
Thanks,

For the css files, you can find them using jQuery.parseHTML() function, but the <script> will be stripped with this so instead we would have to use regex for the <script> tags.
Try:
<script type="text/javascript">
$(document).ready(function () {
$(".form-control").change(function () {
var id = $(this).val();
var dataString = 'id=' + id;
$("#loader_div").show();
$.ajax({
type: "POST",
url: "ajax_load_books.php",
data: dataString,
cache: false,
beforeSend: function () {
//parsing <link>
var $str = $('<output>');
//loading html into fake tag
$str.load("ajax_load_books.php");
//now $str includes all your page code
temp = $.parseHTML(str);
$.each(temp, function (i, el) {
//finding the <link> tag
if (el.nodeName == 'LINK') {
//appending it to the <head> tag
$('head').append("<link rel='stylesheet' href='" + el.getAttribute('href') + "'>");
}
});
//for script we will use regex
var pattern = /<script[^>]+?>.*?<\/script>/gi;
var matches = str.match(pattern);
var scripts = "";
for (var i in matches) {
scripts += matches[i];
}
//appending script tag to <head>
$('head').append(scripts);
},
success: function (html) {
$("#loader_div").hide();
$("#txtHint").html(html);
}
});
});
});
</script>

There is a drawback with this, your stylesheets and script code will repeat. If the above code causes issue running because of the repetition, you should place the code of beforeSend() before the AJAX and have a parameter sent from your AJAX function indicating that when an AJAX is called with this parameter, to execute all the HTML except the stylesheets and js scripts.
