获取元视口标签在桌面上工作 [英] Get meta viewport tag to work on desktop

问题描述

我创建了一个在桌面上启用元视口标签的脚本。但是我似乎不能从视口标签获得指定的宽度。我目前有这个：

I have created a script that enables the meta viewport tag on desktop. However I do not seem to be able to get the specified width from the viewport tag. I currently have this:

var viewportcontent = $( "#myviewport" ).attr('content');
var viewportcontents = viewportcontent.split(",");
//if it starts with 'width='
for (var i = 0; i < viewportcontents.length; i++) {
  if(viewportcontents[i].lastIndexOf('width=', 0) === 0) {
    var wspec = viewportcontent[i].substring(6);
  }
}

问题是这似乎确定，工作。帮帮我！我一直在寻找这个太久了！

The problem is that this seems ok, but does not work. Help! I have been looking at this for too long!

推荐答案

对不起，原来是一个错字！ var wspec = viewportcontent [i] .substring（6）; 必须 var wspec = viewportcontents [i] .substring（6） code>。我必须记住使用更好的变量名称！

Sorry guys... It turned out to be a typo! var wspec = viewportcontent[i].substring(6); had to be var wspec = viewportcontents[i].substring(6);. I have to remember to use better variable names!!!
