TypeError：未定义不是对象（正在评估“ c.trigger”）

Question

I have loaded the jquery-ui-1.8.7.custom.min.js file in my javascript.

But when I run my code:

<script>
  $('.css').datepicker().datepicker(val);
</script>

I get an error like this in the console:

TypeError: undefined is not an object (evaluating 'c.trigger') in jquery/jquery-ui-1.8.7.custom.min.js (line 491)

not sure, why this happening.

Thanks in advance.

Answer 1

Change it to:

<script>
  $('.css').not('.hasDatePicker').datepicker(val);
</script>

Try making your selector more specific. Do you want to run .datepicker() on all alements that have class css ?

EDITED:

Hey, you need to load jQuery itself not only jQuery UI!

Make sure to embed it:

<script src="//code.jquery.com/jquery-latest.min.js"></script>
