javascript - Determine value depending on input types -

I have a type select dropdown, after the selection, Redirects. I want them to be warned that they try to navigate away without saving using this select dropdown.

While selecting this specific type as one of the input types while defining an input type has changed. This is my script, but it does not do the desired work (where .seend1 select the actual type context):

  $ (Document) .on ('change', '.seend1', function () {if ($ (": input") No. ('Send1')) {$ (": input"). Function () {Unsaved = true;});}});  

If unsaved == is correct, users have a warning that there are unsaved changes.

.not () method returns a jQuery object, and any object Is considered a true value in javascript, you should use the length property to check the length of the collection. But here it is not the main problem, the whole argument seems not promising. If you want to exclude an element from the selection, you can use : no in your selector:

  var unsaved = false; $ (Document) .on ('change', '.seend1: not ("select.specific")', function () {unsaved = true;}); $ ('Select.specific'). ('Change', function () {if (unsaved) {// show a model / alert something ...} other {// redirect}});
