Kirat[ad_1] Parameters allows a method to have more flexibility. Sometimes it is necessary to run a method but with different arguments, this is where parameters become handy. For Example (Clarifying): public void calcTotal() { int firstNum= 1; int secondNum=2; System.out.println(firstNum+secondNum); //when we run calcTotal() //output= 3 } This method would correctly print the sum of … Read more

[ad_1] Your sort is working, but you are not seeing the results because you are incorrectly appending your field-items back to your DOM. Try adding a wrapper around all of your field-item divs (radioGroup in the example below) and then append to it instead of trying to overlay the existing divs. Overlaying them is what … Read more
[ad_1] It’s not the ternary that’s the issue, it appears to be how jQuery/HTML is handling the empty string. jQuery is most likely not resolving the property to an explicit false and thus creating an element with a “selected=”” which the browser may just be interpreting as “selected” which I believe is from an old … Read more
