Ajax Post method issue with passing huge data - ajax

Question

folks
we are facing a strange issue with jquery ( 1.8.3) and we are using cakePHP
as per the image
Our assumption is we are sending the data( about 500 +) with ajax call in POST method.
we are having this issue in all the major browsers.
as above( in chrome) , we are getting this error in console we passed 618 destinations in ajax call.
let us know the work around to solve this problem.
My ajax call is as below
function validate_test() {
$("#btn1").empty();
var ele = document.getElementById('frm_searchDateFrom').value;
var ele2 = document.getElementById('frm_searchDateTo').value;
var sub_url = '<?php echo $this->Html->url('/', true); ?>';
var url = sub_url + "admin/reports/check_originator/" + ele +"/"+ ele2 +"/"+ $("#destination").val();
alert(url);
jQuery.ajax({
type: "POST",
datatype: "json",
url: url,
success: function(data)
{
var el = $("select#btn1").multiselect();
var d;
var results=data.split(",");
for(d=0;d<results.length;d++) {
var d;
var v = results[d], opt = $('<option />', {
value: v,
text: v
});
opt.appendTo( el );
el.multiselect('refresh');
}
}
})
}

In your JQuery Ajax method instead of posting all those details as url query para meter send by wrapping those details in a object.
function validate_test() {
$("#btn1").empty();
var ele = document.getElementById('frm_searchDateFrom').value;
var ele2 = document.getElementById('frm_searchDateTo').value;
var sub_url = '<?php echo $this->Html->url('/', true); ?>';
var url = sub_url + "admin/reports/check_originator/";
var formdata=ele +"/"+ ele2 +"/"+ $("#destination").val();//put form data's in an object
alert(url);
jQuery.ajax({
type: "POST",
datatype: "json",
data:formdata,//send the form data object in post
url: url,
success: function(data)
{
var el = $("select#btn1").multiselect();
var d;
var results=data.split(",");
for(d=0;d<results.length;d++) {
var d;
var v = results[d], opt = $('<option />', {
value: v,
text: v
});
opt.appendTo( el );
el.multiselect('refresh');
}
}
})
}
