组合条件以检查是否移动或窗口是否已调整大小

Combining conditions to check if mobile or if window was resized

本文关键字：是否 调整 窗口 移动 条件 检查 组合      更新时间：2023-09-26

如果设备是台式计算机或窗口宽度超过600px，我将尝试运行一些javascript。如果不满足这些条件，那么我会尝试检查该设备是否是移动设备，或者窗口宽度是否小于600px，以便为移动设备运行一些不同的代码。

检查它是否是移动设备确实有效，并且会显示警报，但调整窗口大小则无效。

var winWidth = $(window).width();
// Checking for mobile devices
var isMobile = false;

    isMobile = true;
// Checking if window was resized
var isResized = false;
function resized() {
    $(window).resize(function() {
        // if the width is less than 600 then we set isResized to true
        if ($(window).width() < 600) {
            isResized = true;
        }
    });
}

$(document).ready(function() {
    if (!isMobile ||
        winWidth > 600) {
        // code here
    }
    // if device is a mobile or isResized is true
    else if (isMobile || isResized) {
        alert('resized');
    };
});

我做错了什么？

按如下方式尝试这些代码，在resizing window size上更改它的background，您甚至可以添加警报并尝试。

Fiddle：https://jsfiddle.net/16r1Lwsh/

$(window).on("resize",function(){
 if($(this).width() <= 600){
   $("div").css("background","#111");
 }
 if($(this).width() >= 600){
   $("div").css("background","#f22");
 }
 
});
div{
  width:400px;
  height:400px;
  background:#f22;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div></div>

问题似乎出在这个上

    function resized() {
  $(window).resize(function() {
    // if the width is less than 600 then we set isResized to true
    if ($(window).width() < 600) {
      isResized = true;
    }
  });
}

您已将其放入函数中，但您的目标是获得isResized的值。我也看不出你是如何调用这个resized函数的。

您可以简单地将代码放入函数中，而不是放入函数中

 $(window).resize(function() {
        // if the width is less than 600 then we set isResized to true
        if ($(window).width() < 600) {
          isResized = true;
        }
      });

因此，每次调整大小时，它都会不断更新isResized 的值
