Select all checkboxes issue(jQuery)

I have a little issue, if i select an single checkbox and press f5 the state of the checbox will remain(so it will be checked) but if i use jQuery to select all checkboxes on a page and then press f5 a开发者_开发知识库ll of the checkboxes will blank(so uncheck, only the one's that are handpicked will remain in there state). How can i solve this, so that when i hit refresh everything will remain the same?

the code

jQuery('.sellectall').click(function(){

    $('input:checkbox').attr('checked',true);

});

I assume you're using jQuery 1.6 or later.

If so, use the prop()^[docs] method instead of the attr()^[docs] method.

Then you should get the same behavior as if a user clicked the box.

jQuery('.sellectall').click(function(){

    $('input:checkbox').prop('checked',true);

});

...or set the checked property manually:

jQuery('.sellectall').click(function(){

    $('input:checkbox').each(function() { this.checked = true; });

});
