如何使用html5元素调整视频大小？

Question

I am trying to show a video on fullscreen. 我正在尝试全屏显示视频。 I am using html5 element and code is below . 我正在使用html5元素，下面是代码。

javascript code JavaScript代码

$('document').ready(function()
       {

             var o_vid_width=$('#vid1').width();
              var o_vid_height=$('#vid1').height();
              alert(o_vid_width);// output 300px

           var height = $(window).height();
           var width = $(window).width();
            alert(width)// //output 1280

             if(o_vid_width<=width){

                o_vid_width=width ;
                  alert(o_vid_height)// out put 150 px
             }
});

HTML Code HTML代码

<video id="vid1" autoplay loop >

  <source src="viedos/viedo.mp4" type="video/mp4" >

  <source src="viedos/viedo.ogg" type="video/ogg" >
  Your browser does not support the video tag.
</video>

In above code I am trying to reassign the value of my window width to o_vid_width ,it should be 1280px; 在上面的代码中，我试图将窗口宽度的值重新分配给o_vid_width，它应该为1280px; but it giving me 150 . 但这给了我150。 I dont know why it behaving strange? 我不知道为什么它表现得奇怪？

// I tried below code also even it showing margins on both side .I want that it would cover whole window and when I decrease the size even that it will be shown at whole windows no margins. //我尝试了下面的代码，即使它在两侧都显示了边距。我希望它可以覆盖整个窗口，并且当我减小尺寸时，即使它在整个窗口上都显示没有边距。 var min_w = 300; var min_w = 300; // minimum video width allowed var vid_w_orig; //允许的最小视频宽度var vid_w_orig; // original video dimensions var vid_h_orig; //原始视频尺寸var vid_h_orig;

jQuery(function() { // runs after DOM has loaded jQuery（function（）{//在DOM加载后运行

vid_w_orig = parseInt(jQuery('video').attr('width'));
vid_h_orig = parseInt(jQuery('video').attr('height'));


jQuery(window).resize(function () { resizeToCover(); });
jQuery(window).trigger('resize');

}); }）;

function resizeToCover() { 函数resizeToCover（）{

// set the video viewport to the window size
jQuery('#vid1').width(jQuery(window).width());
jQuery('#vid1').height(jQuery(window).height());

// use largest scale factor of horizontal/vertical
var scale_h = jQuery(window).width() / vid_w_orig;
var scale_v = jQuery(window).height() / vid_h_orig;
var scale = scale_h > scale_v ? scale_h : scale_v;

// don't allow scaled width < minimum video width
if (scale * vid_w_orig < min_w) {scale = min_w / vid_w_orig;};

// now scale the video
jQuery('video').width(scale * vid_w_orig);
jQuery('video').height(scale * vid_h_orig);

} }

if you have the video-size, do it like this: 如果您有视频尺寸，请按照以下步骤操作：

var d = $(window),
    e = $(".secao"),
    f = e.children("div.video"),
    b, c,  j = 1920, k = 1200,
    l = d.width(),
    winH = d.height(),
    winH = winH > 600 ? winH : 600,
    c = Math.max(l / j, winH / k),
    b = Math.round(k * c) + "px";

         f.children("video").css({
            height: b
        })
 });

and set the overflow hidden. 并设置溢出隐藏。

div#intro.secao {
    background-color: #000000;
    height: 100%;
    overflow: hidden;
    position: relative;
}
