大佬教程收集整理的这篇文章主要介绍了jQuery Window Width else if语句，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
$(document).ready(function() { function checkWidth() { var windowSize = $(window).width(); if (windowSize <= 479) { console.log("screen width is less than 480"); } else if (windowSize = 480 && windowSize <= 719) { console.log("screen width is less than 720 but greater than or equal to 480"); } else if (windowSize = 720 && windowSize <= 959) { console.log("screen width is less than 960 but greater than or equal to 720"); } else if (windowSize >= 960) { console.log("screen width is greater than or equal to 960"); } } // Execute on load checkWidth(); // Bind event listener $(window).resize(checkWidth); });
一切都记录在控制台中,除了最后一个if.我究竟做错了什么？
谢谢,
更新：
对于仍然感兴趣的人,我强烈推荐enquire.js插件：
$(document).ready(function() { function checkWidth() { var windowSize = $(window).width(); if (windowSize <= 479) { console.log("screen width is less than 480"); } else if (windowSize <= 719) { console.log("screen width is less than 720 but greater than or equal to 480"); } else if (windowSize <= 959) { console.log("screen width is less than 960 but greater than or equal to 720"); } else if (windowSize >= 960) { console.log("screen width is greater than or equal to 960"); } } // Execute on load checkWidth(); // Bind event listener $(window).resize(checkWidth); });
