javascript - How to preventDefault and disable a href -

-

on first click button click function works, upon clicking again refreshes page click unbind isn't recognized. need prevent default click event disable button after click.

<a href="" class="red-btn2">save property</a>  $(".red-btn2").click(function(event){   event.preventdefault();   $(this).unbind('click');   $(this).css({     'background-color':'#666666',     'text-align':'center'   });   $(this).text("added favorites"); });

if need rest of handler run once, preventdefault() always, can separate them multiple handlers.

then, 1 of them can removed after first use (using jquery's .one() cover you), still leaving preventdefault() in use:

$('.red-btn2')     .click(function (event) {         event.preventdefault();     })     .one('click', function () {       $(this).css({         'background-color':'#666666',         'text-align':'center'       });       $(this).text("added favorites");     });

as have it, event.preventdefault() being removed .unbind('click'), no functions left on element call 2nd click.

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
