height

问题 for some reason, my wrapper div won't equal the same height as my maincontent div. I'll post the code and I would love if someone could help me understand why. Also, I can use jquery if need be Javascript: var wrap=document.getElementById('wrapper'); var left=document.getElementById('maincontent').style.height; wrap.style.height=left; HTML: <div id="wrapper"> <!-- TemplateBeginEditable name="Main Content" --> <div id="maincontent"> </div> <!-- TemplateEndEditable --><!-- TemplateBeginEditable

问题 Is there a way to find the browser height with the toolbars and buttons of the browser, not only the window or document height? 回答1: For the size of the viewport, you use window.innerWidth and window.innerHeight . For the whole window, including decorations, use window.outerWidth and window.outerHeight . Then, all you need to do is subtract one from the other.

问题 I have a very simple code, which annoyingly was working and for the life of me I can not see why it is now failing: function imageSize(img){ var theImage = new Image(); theImage.src = img.attr('src'); var imgwidth = theImage.width; var imgheight = theImage.height; alert(imgwidth+'-'+imgheight); } The "img" variable being passed is the img object, obtained from: jQuery('img') .each(function(){ var imgsrc = jQuery(this); imageSize(imgsrc); }); 回答1: The image may not have loaded yet.

问题 I have a UITableView that is set to not enable scrolling, and it exists in a UIScrollView. I'm doing it this way as the design specs call for something that looks like a table view, (actually there are two of them side by side), and it would be much easier to implement tableviews rather than adding a whole bunch of buttons, (grouped table views).

问题 Here is my debate, the problem is solved, but I cant figure out why the method used on css-tricks.com didnt work. The only reason I can assume it didnt work was because my columns are responsive. Here is a jsfiddle of the problem. Solution 1 Nicolas Gallagher Method Wont work, why. Because my client could at any time add another box (tell me to add another box, or minus a box).

问题 Is it possible to create a div that adjusts to the size of the browser and is also scrollable? I want to use overflow:auto on the div and percentage height of 90% . The structure of the page is <body style="height:100%"> <div id=header style="height:100%">headerinfo</div> <div id=content style="height:100%;overflow:auto">content which is replaced dynamically</div> </body> Will overflow:auto work without a known px height somewhere in the hierarchy? 回答1: In answer to your question, yes
