IE8中的Javascript/css

Question

問題我在IE中正在旋轉一個圖像（時鐘指針）。下面的腳本在一定程度上工作（實際上有動畫正在進行），但它完全離軸旋轉。

我決不是一個使用JavaScript/Jquery的智力遊戲，當談到如何在IE8中正確地做到這一點時，我有點失落。

代碼如下：

(function(jQuery) 
{ 
    jQuery.fn.clock = function(options) 
    { 
    var defaults = { 
     offset: '+0', 
     type: 'analog' 
    }; 
    var _this = this; 
    var opts = jQuery.extend(defaults, options); 

    setInterval(function() { 
     var seconds = jQuery.calcTime(opts.offset).getSeconds(); 
     if(opts.type=='analog') 
     { 
     var sdegree = seconds * 6; 
     var srotate = "rotate(" + sdegree + "deg)"; 
     var rad = Math.PI/180 * sdegree, 
      cos = Math.cos(rad), 
      sin = Math.sin(rad); 
     jQuery(_this).find(".sec").css({"-moz-transform" : srotate, "-webkit-transform" : srotate, "-ms-transform" : srotate, 
             'filter': "progid:DXImageTransform.Microsoft.Matrix(M11="+cos+", M12="+(-sin)+", M21="+sin+", M22="+cos+", SizingMethod='auto expand')"}); 
     } 
     else 
     { 
     jQuery(_this).find(".sec").html(seconds); 
     } 
    }, 1000); 

    setInterval(function() { 
     var hours = jQuery.calcTime(opts.offset).getHours(); 
     var mins = jQuery.calcTime(opts.offset).getMinutes(); 
     if(opts.type=='analog') 
     { 
     var hdegree = hours * 30 + (mins/2); 
     var hrotate = "rotate(" + hdegree + "deg)"; 
     var rad = Math.PI/180 * hdegree, 
      cos = Math.cos(rad), 
      sin = Math.sin(rad); 
     jQuery(_this).find(".hour").css({"-moz-transform" : hrotate, "-webkit-transform" : hrotate, "-ms-transform" : hrotate, 
             'filter': "progid:DXImageTransform.Microsoft.Matrix(M11="+cos+", M12="+(-sin)+", M21="+sin+", M22="+cos+", SizingMethod='auto expand')"}); 
     } 
     else 
     { 
     jQuery(_this).find(".hour").html(hours+':'); 
     } 
     var meridiem = hours<12?'AM':'PM'; 
     jQuery(_this).find('.meridiem').html(meridiem); 
    }, 1000); 

    setInterval(function() { 
     var mins = jQuery.calcTime(opts.offset).getMinutes(); 
     if(opts.type=='analog') 
     { 
     var mdegree = mins * 6; 
     var mrotate = "rotate(" + mdegree + "deg)"; 
     var rad = Math.PI/180 * mdegree, 
      cos = Math.cos(rad), 
      sin = Math.sin(rad); 
     jQuery(_this).find(".min").css({"-moz-transform" : mrotate, "-webkit-transform" : mrotate, "-ms-transform" : mrotate, 
             'filter': "progid:DXImageTransform.Microsoft.Matrix(M11="+cos+", M12="+(-sin)+", M21="+sin+", M22="+cos+", SizingMethod='auto expand')"});     
     } 
     else 
     { 
     jQuery(_this).find(".min").html(mins+':'); 
     } 
    }, 1000); 
    } 
})(jQuery); 


jQuery.calcTime = function(offset) { 
    d = new Date(); 
    utc = d.getTime() + (d.getTimezoneOffset() * 60000); 
    nd = new Date(utc + (3600000*offset)); 
    return nd; 
};

檢查這個例子： 這是工作在IE瀏覽器...

createLine: function(x1, y1, x2, y2, options){ 

       // Check if browser is Internet Exploder ;) 
       var isIE = navigator.userAgent.indexOf("MSIE") > -1; 
       if (x2 < x1){ 
       var temp = x1; 
       x1 = x2; 
       x2 = temp; 
       temp = y1; 
       y1 = y2; 
       y2 = temp; 
       } 
       var line = document.createElement("div"); 
       line.className = "global_dashboard_line"; 

       // Formula for the distance between two points 
       // http://www.mathopenref.com/coorddist.html 
       var length = Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2)); 

       line.style.width = length + "px"; 
       line.style.borderColor = options.color; 
       line.style.zIndex = options.zindex; 
       line.style.borderWidth = options.stroke + " 0px 0px 0px"; 

       if(isIE){ 
       line.style.top = (y2 > y1) ? y1 + "px" : y2 + "px"; 
       line.style.left = x1 + "px"; 
       var nCos = (x2-x1)/length; 
       var nSin = (y2-y1)/length; 
       line.style.filter = "progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=" + nCos + ", M12=" + -1*nSin + ", M21=" + nSin + ", M22=" + nCos + ")"; 
       }else{ 
       var angle = Math.atan((y2-y1)/(x2-x1)); 
       line.style.top = y1 + 0.5*length*Math.sin(angle) + "px"; 
       line.style.left = x1 - 0.5*length*(1 - Math.cos(angle)) + "px"; 
       line.style.MozTransform = line.style.WebkitTransform = line.style.OTransform= "rotate(" + angle + "rad)"; 
       } 
       return line; 
      } 
    } 

這是一個插件的功能，我在HTML畫線做元素...它使用斜線進行旋轉。如果要檢查整個插件去： https://github.com/tbem/jquery.line

這應該在所有的瀏覽器，包括IE8工作：http://jsfiddle.net/SrSus/26/show/

HTML

<ul id="analog-clock" class="analog"> 
    <li class="hour"></li> 
    <li class="min"></li> 
    <li class="sec"></li> 
    <li class="meridiem"></li> 
</ul>
