jQuery append dict to html, how to insert a auto-incrementing id from 1

How to insert a auto-incrementing id from 1 before info.name in jQuery? I use below code to get aggregated data, for example, each quessionId has many related reasons. Below is my partial code of .js code in jQuery:
function fmtQuestionsByID(id,callback){
if(!DATA.questions[id] || !$('#card_'+id) )return;
var project = DATA.projects[DATA.questions[id].projectId];
if(!project)return;
var issueQuestionLists = DATA.alltags.reduce(function(a,b){
if(a[b['quessionId']]) {
a[b['quessionId']].push({name:b['name'],color:b['color'],description:b['description'],reason:b['reason'],question:b['question'],issueId:b['issueId'],department:b['department'],_id:b['quessionId']})
} else{
a[b['quessionId']] = [{name:b['name'],color:b['color'],description:b['description'],reason:b['reason'],question:b['question'],issueId:b['issueId'],department:b['department'],_id:b['quessionId']}]
}
return a;
},{});
for(var i=0;i < DATA.questions[id].tags.length;i++){
var lid = DATA.questions[id].tags[i];
for(var l in issueQuestionLists){
var lb = issueQuestionLists[l]
for(var c=0;c< lb.length;c++){
var lc = lb[c];
if(lc._id == lid){
var info = lc;
console.log('info', info);
$('.tags_question').append('['+info.name+']' + info.description + '。' + 'Reason: '+info.reason+ '。' ||'[no data]' );
}
}
}
}
}
And I use below html to get above data
<div id="questioninfo">
<span class="tags_question"></span>
</div>
In the console, I do have those dictionaries, but why the page only get one dict?
Thanks so much for any help.
Thanks so much for Swati's help, to change .html to .append.

You can define a variable which will store the value of count and then whenever you need to print it first increment it and then add that as well with the data which you are already appending .So your code will look like below :
var count = 0; //declare this
for (var i = 0; i < DATA.questions[id].tags.length; i++) {
//..other codes
var lc = lb[c];
if (lc._id == lid) {
count++; //increment
var info = lc;
console.log('info', info);
//add with other datas
$('.tags_question').append(count + '[' + info.name + ']' + info.description + '。' + 'Reason: ' + info.reason + '。' || '[no data]');
}
}

Javascript Array Passed to PHP Through Ajax

I am trying to pass values from a multiple select listbox through Ajax to PHP. I saw some examples in Jquery and JSON, however I am trying to accomplish this just in plain old javascript (Ajax). Here is what I have so far (simplified):
Ajax:
function chooseMultiEmps(str)
{
var mEmpList2 = document.getElementById('mEmpList'); //values from the multi listbox
for (var i = 0; i < mEmpList2.options.length; i++) //loop through the values
var mEmpList = mEmpList2.options[i].value; //create a variable to pass in string
if (window.XMLHttpRequest)
{
xmlhttp = new XMLHttpRequest();
}
else
{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function()
{
if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
{
//specific selection text
document.getElementById('info').innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("POST", "myPage.php", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
var queryString = "&mEmpList=" + mEmpList; //query string should have multiple values
xmlhttp.send(queryString);
}
I can run an alert(mEmpList) and get each value in individual message boxes, however when I retrieve and echo the $_POST['mEmpList'], I get only the first value. Also, when I alert(queryString), I get only one value.
I think I need to create a comma delimited array, and then pass that through the query string. From there, I can use the PHP implode/explode feature to separate the values. Any assistance would be greatly appreciated.

here:
for (var i = 0; i < mEmpList2.options.length; i++) //loop through the values
var mEmpList = mEmpList2.options[i].value; //create a variable to pass in string
you are redefining your mEmpList over and over again, that means only the last value is send
You could do:
var mEmpList = '';
for (var i = 0; i < mEmpList2.options.length; i++) { //loop through the values
mEmpList = mEmpList +','+ mEmpList2.options[i].value; //create a variable to pass in string
}
Also your queryString is not ok, no need for &
var queryString = "mEmpList=" + mEmpList;
That way at the end you will have all values delimite by comma ,
In PHP you can use explode to loop each value:
<?php
$string = explode(',' $_GET['mEmpList']);
for($i=1; $i<count($string); $i++){
echo $string[$i]."<br />";
}
?>

How we can get that at a particular place marker is present or not

I am making dynamic markers. I got success in that. But here is problem that if there is two same lat-log then it place only one marker there.
Instead of that I want to change the marker icon if there is two same lat-log.
I am taking lat-log from database.
Any help.

Yes, I have found the solution of this problem.
I am using two array
The code is as following:
var contentStrings = new Array();
var markers = new Array();
and getting the position
var pos = marker.getPosition();
var isPresent = false;
var index;
for(var i = 0; i < markers.length; i++) {
if(String(pos) == String(markers[i])) {
isPresent = true;
index = i;
}
}
if(isPresent) {
contentString = contentStrings[index] + '<div><br/> Tutor Name : '+data.name+'<br/>Link : '+data.url+'</div>';
} else {
markers.push(pos);
contentString = '<div> Tutor Name : '+data.name+'<br/>Link : '+data.url+'</div>';
contentStrings.push(contentString);
}
Its really working fine.

why not use jQuery if you are including jQuery library?
var checkbox_val=jQuery("#CHECKBOX_ID_HERE").val();//gets you the value regardless if checked or not
var checkbox_val=jQuery("#CHECKBOX_ID_HERE").attr("checked"); //returns checked status
or
var global_variable=""; //should be initialized outside any function
jQuery("#FORM_ID_HERE").children(":input[type='checkbox']").each(function(){
if (jQuery(this).attr("checked"))global_variable+="&"+jQuery(this).attr("name")+"="+jQuery(this).val();
});
this is just a suggestion to start from, not ideal. the ideal part is to use [] in your form.
