i am trying to send multiple data using j query $.ajax method to my php script but i can pass only single data when i concatenate multiple data i get undefined index error in my php script tat means the ajax request is made but data is not sent i need to know how should i format multiple data to successively send it to processing script in name vale pair here is what i have written
<script>
$(document).ready(function() {
$('#add').click(function () {
var name = $('#add').attr("data_id");
var id = $('#add').attr("uid");
var data = 'id='+ id & 'name='+ name; // this where i add multiple data using ' & '
$.ajax({
type:"GET",
cache:false,
url:"welcome.php",
data:data, // multiple data sent using ajax
success: function (html) {
$('#add').val('data sent sent');
$('#msg').html(html);
}
});
return false;
});
});
</script>
<span>
<input type="button" class="gray_button" value="send data" id="add" data_id="1234" uid="4567" />
</span>
<span id="msg"></span>
var my_arr = new Array(listingID, site_click, browser, dimension);
var AjaxURL = 'http://example.com';
var jsonString = JSON.stringify(my_arr);
$.ajax({
type: "POST",
url: AjaxURL,
data: {data: jsonString},
success: function(result) {
window.console.log('Successful');
}
});
This has been working for me for quite some time.
var value1=$("id1").val();
var value2=$("id2").val();
data:"{'data1':'"+value1+"','data2':'"+value2+"'}"
Change var data = 'id='+ id & 'name='+ name;
as below,
use this instead.....
var data = "id="+ id + "&name=" + name;
this will going to work fine:)
I would recommend using a hash instead of a param string:
data = {id: id, name: name}
you can use FormData
take look at my snippet from MVC
var fd = new FormData();
fd.append("ProfilePicture", $("#mydropzone")[0].files[0]);// getting value from form feleds
d.append("id", @(((User) Session["User"]).ID));// getting value from session
$.ajax({
url: '@Url.Action("ChangeUserPicture", "User")',
dataType: "json",
data: fd,//here is your data
processData: false,
contentType: false,
type: 'post',
success: function(data) {},
var CommentData= "u_id=" + $(this).attr("u_id") + "&post_id=" + $(this).attr("p_id") + "&comment=" + $(this).val();
var data = 'id='+ id & 'name='+ name;
The ampersand needs to be quoted as well:
var data = 'id='+ id + '&name='+ name;
var value1=$("id1").val();
var value2=$("id2").val();
data:"{'data1':'"+value1+"','data2':'"+value2+"'}"
You can use this way to pass data
