Question

我想解一下谷歌建议清单,因此我对建议有一个自动汇编,但我也想到bold。如果与投入的价值不相称,就是一个例子:。 JsBin

各位可以看到,我已经为安保部提出建议设定了bold,如果建议与价值相同,Im试图使之正常:

if($( #input ).val() == $( .ui-autocomplete li a ).text()){
       $( .ui-autocomplete li a ).css("font-weight", "normal");
}

No luck so far. What am I doing wrong?

Answer 1

$(ui-autocomplete li a ).text( isn t comparing any one>lement, or each of them individual, but this consider contenate all potential, so that at the time You ve打上了“gho”的比较:

if ("gho" == "ghost riderghost huntersghost rider 2ghost adventuresghost rider spirit of vengeanceghanaghbghetto hikesghostbusters 3ghost") {

}

另一个性质相同的问题是:

$( .ui-autocomplete li a ).css("font-weight", "normal");

will change the style for all found matches. Neither behaviour isn t what you want, I suspect.

你们可能想要的是:

$("#input").on( keyup , function(e){
  var val = $( #input ).val();
  $.each($( .ui-autocomplete li a ), function() {
    if (val == $(this).text()) {
      $(this).css("font-weight", "normal");
    }
  });
});

Answer 2

审判

$("#input").on( keyup , function(e){
      var val = $( #input ).val();
      $.each($( .ui-autocomplete li a ), function() {
        if (val == $(this).text()) {
          $(this).addClass( fontWeight );
        }
      });
});

c 应为

  .ui-autocomplete li a {
    font-weight: bold;
  }
  .fontWeight{
    font-weight:normal !important;
  }
