Using jquery to determine screen width
提问by dsol828
Having trouble getting this script to run properly on an iphone 6. Keeps coming up as "not mobile". What am I missing?
无法让此脚本在 iphone 6 上正常运行。不断出现“非移动”。我错过了什么？
$(document).ready(function(){
if ($(window).width < 700){
alert("mobile");
}
else {
alert("not mobile");
}
});
EDIT: apologies, the code I typed here had a typo, but was not the cause for my issue. I had inaccurate info on iphone resolution. Thanks everyone!
编辑：抱歉，我在这里输入的代码有错别字，但不是我问题的原因。我有关于 iphone 分辨率的不准确信息。谢谢大家！

The iPhone 6 display has a resolution of 1334x750. When emulating iPhone6 in chrome dev tools the width is reported as 980(I don't know if this is accurate).
iPhone 6 显示屏的分辨率为 1334x750。在 chrome 开发工具中模拟 iPhone6 时，宽度报告为980（我不知道这是否准确）。

Also, as others have noted, replace $(window).widthwith $(window).width()
此外，正如其他人所指出的，替换$(window).width为$(window).width()

Well, ignoring what ekuusela saidabout screen resolution, you seem to have forgotten your parentheses after width, which is a method, not a field. To fix this, just add ()after it:
好吧，忽略ekuusela 说的屏幕分辨率，你好像忘记了后面的括号width，是方法，不是字段。要解决此问题，只需在()其后添加：
if ($(window).width() < 700)
See the documentation for width()for more info.
有关更多信息，请参阅文档width()。

JQuery uses $(window).width(). It's a function, not a property.
JQuery 使用$(window).width(). 它是一个函数，而不是一个属性。
回答by Bill Criswell
You would want .width(), not just .width. Also, log it and make sure it's what you're expecting.
你会想要的.width()，不只是.width。此外，记录它并确保它是您所期望的。
