如果计数 == 0 和其他计数 == 0

if count == 0 AND otherCount == 0

我有 2 个计数器“goFoods”和“count”。我想要一个 if 语句来检查 goFoods 是否已达到 9 AND 计数是否超过 6,然后使 TryAgain div 可见。我已经试过了,但是没有用。

function checkTryAgain() {
    if(goFoods == 9; && count >= 6; ){
    $("#TryAgain").css({visibility: 'visible',});
    
}}

如果您从 if 语句中删除分号,它会正常工作:

let goFoods = 9, count = 6

function checkTryAgain() {
    if(goFoods == 9 && count >= 6){
    $("#TryAgain").css({visibility: 'visible',});
    
}}

checkTryAgain()
#TryAgain{
  visibility: hidden;
}
