How do I push new values to the following javascript array?

json = {"cool":"34.33","alsocool":"45454"}

I tried json.push("coolness":"34.33"); but it didn't work.

Don't need to push. Try this...

Code:

json['cool'] = '34.33';
json['alsocool'] = '45454';

JMRKER's example is to replace values.

To add new ones just do like the example provided, but with new indexes.

Code:

json['newIndex'] = 'newValue';

And because JS is cool, you can also do

Code:

json.newIndex = 'newValue'

It's the same syntax to replace or create new elements of the array.

To display contents

Code:

For (var index in json) {
  alert(index+' : '+json[index]);
}

Sorry I should have been more clear you see this array below, notice it has two separate user values in there. If i wanted to add a third user value into this array with those same fields how would i do that? Thanks you guys/girls btw!

PHP Code:


var contacts = [{"LNAME":"Saula.","FNAME":"Sir","MIDDLE":"","TITLE":"Ph.D.","JOB":"Academic Dean of Engineering","SECTION":"Dean's Office","EMAIL":"sirsaulajr@ttasdsau.edu","IMG":"/coe/dean/”},{"LNAME":"sdsada","FNAME":"John","MIDDLE":"bab","TITLE":"Ph.D.","JOB":"Senior Associate Dean","SECTION":"Dean&#039;s Office","EMAIL":"basdas@masma.com","IMG":"/coe/dean/images/ "}];

You'd do:

Code:

contacts.push({"LNAME":"sdsada","FNAME":"John","MIDDLE":"bab","TITLE":"Ph.D.","JOB":"Senior Associate Dean","SECTION":"Dean&#039;s Office","EMAIL":"basdas@masma.com","IMG":"/coe/dean/images/"});

hmm last question; I am trying to push to the javascript array after looping 200 times through the member array to push every member that matches the department selected description into the javascript array., However it fails

PHP Code:


<? $i = 0 ;
    while( $i < 200)
        {
            
            if ($members[$i]['department'] == $depttts){
             break;
                  echo "<script type='text/javascript'>contacts.push({"NAME":"SirSaula","TITLE":"John","CONTACT":"bab","RESEARCH":"Ph.D."});</script>";
            
            }
            else {
              $i++;
            }
            
        }
        
    ?>

This does not answer your last question, but it may provide food for thought ...

Code:

<html>
<head>
<title> Untitled </title>
<script type="text/javascript">

var contacts = [ {  // literal assignment
  "LNAME":"Saula","FNAME":"Sir","MIDDLE":"","TITLE":"Ph.D.",
  "JOB":"Academic Dean of Engineering","SECTION":"Dean's Office",
  "EMAIL":"sirsaulajr@ttasdsau.edu","IMG":"/coe/dean/"
 },
 {
  "LNAME":"Student","FNAME":"John","MIDDLE":"Q.","TITLE":"Ph.D.",
  "JOB":"Associate Dean","SECTION":"Dean's Office",
  "EMAIL":"basdas@masma.com","IMG":"/coe/dean/images/"
 }
];

contacts.push( {  // active literal assignment
  "LNAME":"Student","FNAME":"Mary","MIDDLE":"K.","TITLE":"MS.",
  "JOB":"Senior Associate Dean","SECTION":"Dean's Office",
  "EMAIL":"basdas@masma.com","IMG":"/coe/dean/images/"
 }
);

function addToContacts(newString) {  // dynamic assignment
  var tarr = newString.split(',');
  contacts.push( {
   "LNAME":tarr[0],"FNAME":tarr[1],"MIDDLE":tarr[2],"TITLE":tarr[3],
   "JOB":tarr[4],"SECTION":tarr[5],"EMAIL":tarr[6],"IMG":tarr[7]
  } );
}

function currentContacts() {  // display json array
  var str = '';
  for (var i=0; i<contacts.length; i++) {
    str += '#'+(i+1)+' '+contacts[i].FNAME+' '+contacts[i].LNAME+'\n'+contacts[i].JOB+'\n\n';
  }
  alert(str);
}

currentContacts();
// following information might come from an ajax text file
addToContacts('LName,FName,MI,Title,Job,Faculty,Email,Picture');
currentContacts();

</script>
</head>
<body>

</body>
</html>
