Storing The Date into a Var From a Popup Window Date Picker

Hello,

I really need your help with one.

How can I use the following code below to save the date from my popup window datepicker back into a var and relay it back onto its parent page?

I can't seem to figure this out:

<html>
<head>
<script>
function open_cal() {
  var str_html = ""
      +  "<!DOCTYPE html>\n"
      +  "<html lang=\"en\">\n"
      +  "<head>\n"
      +  "<meta charset=\"utf-8\">\n"
      +  "<title>CALENDAR</title>\n"
      +  "<link href=\"jq/jquery-ui.css\" rel=\"stylesheet\" type=\"text/css\">\n"
      +  "<script src=\"jq/jquery.min.js\" type=\"text/javascript\"></" + "script>\n" 
      +  "<script src=\"jq/jquery-ui.min.js\" type=\"text/javascript\"></" + "script>\n"
      +  "<script src=\"jq/datepicker.js\" type=\"text/javascript\"></" + "script>\n"
      +  "</head>\n"
      +  "<body>\n"
      +  "<div id=\"text\" style=\"font: bold 10pt Tahoma\">Enter Approval Date:</div>\n"
      +  "<div id=\"datepicker\"></div>\n"
      +  "</body>\n"
      +  "</html>"
          
var j = window.open("","CALENDAR","width=200,height=250,status=no,resizable=yes,top=200,left=200")
  j.opener = self;
  j.document.write(str_html);
}
</script>  
</head>
<body>
<input onclick="open_cal()" type="button" value="Open" name="B1">
</body>
</html>

Open in new window


DatePicker.js:
$(function() {
  $( "#datepicker" ).datepicker({ 
    dateFormat: 'dd/mm/yy',
    onSelect: function(dateText, inst) { 
      alert(dateText)
      window.close()
    } 
  })
});

Open in new window


Any help with this is greatly and mostly appreciated.

Thanks in advance,

Cheers,

1) I formatted your code to be more readable
2) you forgot to do
j.document.close();
after the .write(...)
3) Why do you set the opener to self?????
4) If you don't you can just do
opener.dateValue = dateText
or
opener.someFunction(datetext);

but I also suggest you format like this - much more readable
<html>
<head>
<script>
function open_cal() {
  var str_html = ''
      +  '<!DOCTYPE html>\n'
      +  '<html lang="en">\n'
      +  '<head>\n'
      +  '<meta charset="utf-8">\n'
      +  '<title>CALENDAR</title>\n'
      +  '<link href="jq/jquery-ui.css" rel="stylesheet" type="text/css">\n'
      +  '<script src="jq/jquery.min.js" type="text/javascript"><\/script>\n' 
      +  '<script src="jq/jquery-ui.min.js" type="text/javascript"><\/script>\n'
      +  '<script src="jq/datepicker.js" type="text/javascript"><\/script>\n'
      +  '</head>\n'
      +  '<body>\n'
      +  '<div id="text" style="font: bold 10pt Tahoma">Enter Approval Date:</div>\n'
      +  '<div id="datepicker"></div>\n'
      +  '</body>\n'
      +  '</html>'
          
var j = window.open('','CALENDAR','width=200,height=250,status=no,resizable=yes,top=200,left=200')
//  j.opener = self; // this cannot be what you want!!!
  j.document.write(str_html);
  j.document.close();
}
</script>  
</head>
<body>
<input onclick='open_cal()' type='button' value='Open' name='B1'>
</body>
</html>

Hi mplungjan,

I tried what you have posted,

and for the life of me, still cannot get this to work.

'opener.dateValue is null or not an object'

<html>
<head>
<script>


function test() {

alert(opener.dateValue)

}



function open_cal() {
  var str_html = ''
      +  '<!DOCTYPE html>\n'
      +  '<html lang="en">\n'
      +  '<head>\n'
      +  '<meta charset="utf-8">\n'
      +  '<title>CALENDAR</title>\n'
      +  '<link href="jq/jquery-ui.css" rel="stylesheet" type="text/css">\n'
      +  '<script src="jq/jquery.min.js" type="text/javascript"><\/script>\n' 
      +  '<script src="jq/jquery-ui.min.js" type="text/javascript"><\/script>\n'
      +  '<script src="jq/datepicker.js" type="text/javascript"><\/script>\n'
      +  '</head>\n'
      +  '<body>\n'
      +  '<div id="text" style="font: bold 10pt Tahoma">Enter Approval Date:</div>\n'
      +  '<div id="datepicker"></div>\n'
      +  '</body>\n'
      +  '</html>'
          
var j = window.open('','CALENDAR','width=200,height=250,status=no,resizable=yes,top=200,left=200')
  j.document.write(str_html);
  j.document.close();
}
</script>  
</head>
<body>
<input onclick='open_cal()' type='button' value='Open' name='B1'>

<input onclick='test()' type='button' value='GetTheDate' name='B2'>

</body>

or better:

function test(val) {
  dateValue=val;
  alert(dateValue);
}
