Can I Force Jquery Dirtyform to See A Form As Dirty?

We are using the JQuery dirtyform plugin to display a warning to users if they change form data and try to navigate away from the page and it works well.

One additional thing I would like to do is to force a form to be dirty when the page first loads. I can't figure out how to do this - I've attempted using javascript to change values on the form fields, I've tried adding the "changed" class to form fields, but neither of these trigger the warning dialog when I navigate away from the page.

Is there a way to do this?

ANSWE开发者_Python百科R:

$(document).ready(function() {
   $("form").dirty_form({includeHidden: true});
   $("a").dirty_stopper();

   $("#dummy").val("1");
   $("#dummy").blur();
});

and in the html:

<input type="hidden" name="dummy" id="dummy" value="0" />

$("#myFormID").find("input").change();

You'll obviously need to change the selectors, but I think this is what you want. It just triggers jQuery's "change" event (which is what Dirty Form is listening for) on the selected elements.

I solved this without having to use hidden fields by adding this function to the plugin:

$.fn.set_form_dirty = function(){
    $(this).data("dirty", true);
};

Then I call this from the pages that I want to be dirty from start by adding this piece of code (in this case setting all forms on the page to dirty):

<script type="text/javascript">
    $(document).ready(function() {
        $("form").set_form_dirty();
    });
</script>

Have you tried to apply the class "changed" to an input?

Whenever an input value changes it will get the 'changed' class added to it
