qtip and html data in title="" is causing conflict

I'm trying to load html content into visjs timeline and using qtip2 to display a tooltip when a hyperlink inside a timeline is clicked. This tooltip needs to display html content, so it has "" in it, which causes a problem when its inserted into a title="". Normally i would be able to use a single quote in the title='<-html - content->' so it should be able to handle the quotes. But now i'm facing a problem, because i'm trying to do this from inside javascript which already uses a single quote from the javascript itself.
if i want to add a item to visjs timeline, i need to insert new items to the timeline like this.
{id: <?php echo $key; ?>, group: <?php echo $aspects['group'][$key]; ?>, content: '<a title="<?php if(isset($aspects['interpretation'][$key])): echo $aspects['interpretation'][$key]; endif;?>" role="button"><?php echo $aspects['symbols'][$key]; ?></a>', start: new Date(<?php echo $aspects['dates']['start'][$key]['year']; ?>, <?php echo $aspects['dates']['start'][$key]['month'] - 1;?>, <?php echo $aspects['dates']['start'][$key]['day'];?>, <?php echo $aspects['dates']['start'][$key]['hour'];?>, <?php echo $aspects['dates']['start'][$key]['min'];?>), end: new Date(<?php echo $aspects['dates']['end'][$key]['year']; ?>,<?php echo $aspects['dates']['end'][$key]['month'] - 1; ?>, <?php echo $aspects['dates']['end'][$key]['day']; ?>, <?php echo $aspects['dates']['end'][$key]['hour']; ?>, <?php echo $aspects['dates']['end'][$key]['min']; ?> ) },
But as you can see, content:' href etc ' already uses a single quote. So how can i escape this html quotes so it doesn't cause a conflict? I tried things like title = \" \" in the href, but i am not finding any solution yet to solve my problem.

You should use htmlspecialchars before outputting your PHP variables.

Try using templating strings in JavaScript.
var string = `hello " and ' work in this string`;

rest of the string after single quote is thrown away

CKEDITOR.instances.content.getData() has a text like This is a' ball .
i send the following data to a php page using ajax to store it to a database
var data="answer_body="+CKEDITOR.instances.content.getData()+"&userpost_post_id=<?php echo $contents[0]->post_id;?>&users_user_id=<?php echo $userdata->user_id; ?>";
But the answer body throws away rest of the text after quote.
$answer=addslashes($_POST['answer_body']);
echo $answer; // it contains only -----------This is a
how i can solve this problem?

Try below Ajax code to send data from client to server
$.ajax({
type: 'POST',
url: "Here_Your_Server_Url",
data: {
answer_body: encodeURIComponent(CKEDITOR.instances.content.getData()),
userpost_post_id: "<?php echo $contents[0]->post_id; ?>",
users_user_id: "<?php echo $userdata->user_id; ?>"
}
})
Try below code in PHP
$strAnswerBody = urldecode($_POST['answer_body']);

Ajax function on button press

I am trying to get information to post via PHP on button click, everything in my code looks right, and when I view the page source everything is filled in the way it should be. When I pull up the debugger when the button is clicked it does not make any calls at all, here is my button
<button type="button">Continue</button>
here is my ajax call
$(document).ready(function() {
$("button").click(function(){
var Id = <?php echo $give ?>;
var Ids = <?php echo $rec ?>;
var ex = <?php echo $exchange ?>;
var ret = <?php echo $tost ?>;
var email = <?php echo $email ?>;
var name = <?php echo $name ?>;
var pe = <?php echo $pe ?>;
var re = <?php echo $re ?>;
$.post("postts.php", {
Id: Id,
Ids: Ids,
ex: ex,
ret: ret,
email: email,
name: name,
pe: pe,
re: re
}, function(data){
alert(data);
$("p").text(data);
}, 'json' );
});
});
all of my vars will populate with the correct information, I just don't know why when I click the button it does nothing. I am not sure if I have made a typo, or if my syntax is wrong, this is only the second time I have done something like this.

You have error in writing variable values from PHP to JavaScript, you must wrap PHP output by quotation marks, so JavaScipt will "see" string ;)
instead of:
var email = <?php echo $email ?>;
write:
var mail = '<?php echo $email ?>';

How to escape quotes and special chars from string and pass it to JS onClick method?

I have PHP Script / HTML
$string1 = 'Foo';
$string2 = 'Bar';
$string3 = 'This string contains some URL';
$string4 = 'This string contains multi-line short description which contains single quotes, double quotes and some comma characters as well.';
Here is my onClick
<a class="someClass" title="someTitle" href="#" onclick="someFunction('<?php echo $string1; ?>', '<?php echo $string2; ?>', '<?php echo $string3; ?>', '<?php echo $string4; ?>')">Click Here</a>
But while receiving, I am getting all sorts of string parsing errors on someFunction()

In php side use:
<?php echo addslashes($string1); ?>
And inside someFunction( string1 ) use:
string1 = string1.replace(/\\/g, '');
To get the normal value of the string;

Updated
&& is WRONG in Query string , its only & . The && operator comes ONLY in logical operations like a==2 && b==2
Use proper quotes like following in JS Ajax code to concatenate PHP cariables.
url: 'update.php?cids='+<?php echo $dt['callerid'] ?>+'&eid='+<?php echo $dt['eid'] ?>+'&sts='+<?php echo $dt['status'] ?>,

Use Double quotes instead of single quotes in start and end like this
url: "update.php?cids= <?php echo $dt['callerid'] ?> && eid= <?php echo $dt['eid'] ?> && sts= <?php echo $dt['status'] ?>"
and check your console also for errors

You should check for the spaces after = and lookout for quotes and make a single & ampersands too:
url: 'update.php?cids=<?php echo $dt["callerid"] ?>&eid=<?php echo $dt["eid"] ?>&sts=<?php echo $dt["status"] ?>',

There are issues with :
Quotes
&& double ampersands.
space after =
