javascript - 我在 html 中创建了一个展开按钮，它更改图标并显示内容（并反转它）但媒体查询第二次（不是第一次）

问题描述

$('#click1').click(function () {
    var media = window.matchMedia("(max-width: 900px)")
    var media2 = window.matchMedia("(min-width: 901px)")
    if($(this).text() == 'unfold_more')
         $(this).text('unfold_less');
    else
        $(this).text( 'unfold_more');
    var x = document.getElementById("myDIV1");
    
    console.log("before:", x.style.display)
    
  if (x.style.display === "none" && media.matches) {
    x.style.display = "grid";
  } else if (x.style.display === "grid" && media.matches) {
    x.style.display = "none";
  } else if (x.style.display === "flex") {
    x.style.display = "none";
  }  else {
    x.style.display = "flex";
  }

    console.log("after:", x.style.display)

我想要它做的是在大屏幕上显示 flex 样式的 div，在较小的屏幕上显示网格样式的 div。它可以工作，但第二次切换按钮。我第一次单击按钮时，它显示 flex 类型的 div。

x.style.display在 CSS 中是display: none

var media = window.matchMedia("(max-width: 900px)")

$('#click1').click(function() {
  if ($(this).text() == 'unfold_more')
    $(this).text('unfold_less');
  else
    $(this).text('unfold_more');
    
  var x = document.getElementById("myDIV1");
  if (x.style.display === "flex") {
    x.style.display = "none";
  } else if (x.style.display === "flex") {
    x.style.display = "none";
  } else if (x.style.display === "grid" && media.matches) {
    x.style.display = "none";
  } else if (x.style.display === "none" && media.matches) {
    x.style.display = "grid";
  } else {
    x.style.display = "flex";
  }
