For example if I want to do something if parent element for used element hasn't got ul tag as next element, how can I achieve this?
I try some combination of .not() and/or .is() with no success.
What's the best method for negate code of a if else block?
My Code
if ($(this).parent().next().is('ul')){ // code... } I want to achieve this
Pseudo Code:
if ($(this).parent().next().is NOT ('ul')) { //Do this.. } 2 Answers
You can use the Logical NOT ! operator:
if (!$(this).parent().next().is('ul')){ Or equivalently (see comments below):
if (! ($(this).parent().next().is('ul'))){ For more information, see the Logical Operators section of the MDN docs.
0Try negation operator ! before $(this):
if (!$(this).parent().next().is('ul')){
