EJB entity manager remove() result in Cannot delete or update a parent row

Question

I use jquery .find('input')[0] which gives me a element like this

<input name='world' value='hello'>

I want to change the value of this textfield. I then find('input')[0].val('') , but it gave me a type error. Any insight please ?

Answer 1

Use :first to get the first input.

find('input:first').val('your value here') 

or

find('input:eq(0)').val('your value here'); 

When you do find('input')[0] , you're actually getting the DOM element and since it's no longer wrapped in a jquery object the .val property will not work.

If you really want to use your previous code then you could use the native DOM property value

find('input')[0].value
