javascript - 单击设置后从播放更改为暂停

问题描述

我将如何设置它以便在单击“设置”后按钮从播放变为暂停。

按“设置”将触发 svg 更改为暂停按钮。

代码： https ://jsfiddle.net/192h0w85/195/

    (function iife() {
    "use strict";
    const player = document.getElementById("player");
    const button = document.getElementById("button");
    const value = document.getElementById("input");
    const sent = document.getElementById("sent");
    button.addEventListener("click", function() {
        this.classList.toggle('is-playing')
        if (player.paused) {
            player.play();
        } else {
            player.pause();
        }
    });
    sent.addEventListener("click", function() {
        player.volume = 1.0;
        player.src = value.value;
    });
}());

解决方案

您已经添加了按钮单击事件

您只需触发该点击即可更改图标

因此，您的代码将如下所示

(function iife() {
  "use strict";
  const player = document.getElementById("player");
  const button = document.getElementById("button");
  const value = document.getElementById("input");
  const sent = document.getElementById("sent");

  button.addEventListener("click", function() {
    this.classList.toggle('is-playing')
    if (player.paused) {
      player.play();
    } else {
      player.pause();

    }
  });

  sent.addEventListener("click", function() {
    player.volume = 1.0;
    player.src = value.value;
    button.click();
  });
}());

笔记： button.click();

(function iife() {
  "use strict";
  const player = document.getElementById("player");
  const button = document.getElementById("button");
  const value = document.getElementById("input");
  const sent = document.getElementById("sent");

  button.addEventListener("click", function() {
    this.classList.toggle('is-playing')
    if (player.paused) {
      player.play();
    } else {
      player.pause();

    }
  });

  sent.addEventListener("click", function() {
    player.volume = 1.0;
    player.src = value.value;
    button.click();
  });
}());
