im practicing on creating a html using jquery cookies. i already know how to set, get, and delete cookies. one thing i don't know is how to display the set cookies on the next page. i have this html ccodes:
<FORM id = 'login' meth0d = 'post' action = 'Coutput.html' >
<input id = 'name' type = "text" value = ''>
<input id="btnSet" type="submit" value="Go"/>
<input id="btndelete" type="button" value="delete cookie"/>
</form>
and i have this javascript code:
$('form#login :submit').addClass('inputSubmitBtn').click(function(){
if($('#name').val() == "" ){
$("#name").focus();
alert('please input name');
return false;
}
else{
$.cookie("cookie_name", null);
$.cookie('cookie_name', $('#name').val());
alert('new cookie name' +$('#name').val()));
$('#name').append($.cookie('cookie_name'));
};
});
questions:
why is it that everytime i used $.cookie('cookie_name', $('#name').val(), { expires: null, path: '/', domain: 'cegi1.html', secure: true });
, my cookie os always set to null, though i set another one, it always returns null?
how can i display my newly set cookie in Coutput.html? (ex. name = luke, output in Coutput.html must be "welcome luke")
thanks for reading. please help..
It seems that <input id="btnSet" type="submit" value="Go"/>
is submitting form to the other page before evaluating $('form#login :submit').click(function()
. And also you have got error on alert('new cookie name' +$('#name').val()));
. This should work.
<script src="jquery.js"></script>
<script src="jquery.cookie.js"></script>
<script>
$(function ()
{
$("#btnSet").click(function(){
if($('#name').val() == "" ){
$("#name").focus();
alert('please input name');
return false;
}
else{
$.cookie("cookie_name", null);
$.cookie('cookie_name', $('#name').val());
alert('new cookie name' +$('#name').val());
$('#name').append($.cookie('cookie_name'));
};
window.location = $(this).parent('form').attr("action");
});
})
</script>
<form id = 'login' meth0d = 'post' action = 'Coutput.html' >
<input id ="name" type = "text" value="">
<input id="btnSet" type="button" value="Go"/>
<input id="btndelete" type="button" value="delete cookie"/>
</form>
On my Coutput.html
i have
<script src="jquery.js"></script>
<script src="jquery.cookie.js"></script>
<script>
alert($.cookie("cookie_name") );
</script>
If you want to delete the cookie on window close, then use window.unload
event and on jquery perhap this . And you can delete cookie by resetting it to null.
