width

问题 I'm quite new to jQuery, could someone please tell me if I have expressed the above 'if' statement correctly? I basically want something to run if the width of my variable equals 900px. My variable is var $brewapp = $('#brewapp'); Thanks. if (($brewapp).width == '900px') { //what i want it to do } 回答1: .width is a function, that returns a number. So your test should look like this: if ($brewapp.width() === 900) I suggest the Mozilla Javascript docs if you want to deepen your JS knowledge. 回答2

I have sub-views that rely on the width of the cell: there is a label that always needs to be just inside the right edge of the cell. The cells appear in a grouped table view.

问题 I'm using bootstrap in an app and as you can see (below) when printing the browser (left side) is using a really small width when printing (right) so the responsive layout is moving all the right site elements below the left side ones and the printing version won't fit in one single page. Do you know how can I force the browser to keep the right width? Thanks, Remo . 回答1: I had a very similar problem. Ensuring the responsive css is enabled only for media="screen" solved it. <link href="assets
