Question

我有一个按钮名称，当我单击按钮时，加载程序将显示3秒钟（带有timeInterval函数），然后在3秒钟后出现模态。问题是，当我单击分配按钮时，加载程序出现，然后在3秒后消失，但是当我单击分配按钮时，第二次加载程序出现，但突然在1或2秒后消失。为什么加载程序没有花3秒钟的时间与第一次点击相同？

javascript / jquery代码

function spiner() {
    $(".loader-spiner-outer.class-none-view").removeClass("class-none-view");
    setInterval(function() {
        $(".loader-spiner-outer").addClass("class-none-view");
    }, 800);
    setTimeout(function() {
        $("#myModal").show();
    }, 900);
};
$(".close").click(function() {
    $("#myModal").hide();
});

Answer 1

尝试一下：

$(".close").click(function ()
{
  $("#myModal").hide();
});

function spiner()
{
  $(".loader-spiner-outer").addClass("class-none-view"); 
  setTimeout(function ()
  {
    $(".loader-spiner-outer").removeClass("class-none-view");
    setTimeout(function ()
    {
      $("#myModal").show();
    }, 3000);
  }, 3000);
}

.loader-spiner-outer
{
  display: none;
}
.loader-spiner-outer.class-none-view
{
  display: block;
}

也不要使用setInterval(() => {})，因为它是一个重复计时器。使用setTimeout(() => {})，因为它只会运行一次。

'setInterval' vs 'setTimeout'

函数setInterval（）在第二次调用时无法正常工作
