JavaScript在IE与Firefox几个写法不同的地方

//css float document.getElementById("header").style.styleFloat = "left"; //ie document.getElementById("header").style.cssFloat = "left"; //Firefox//获取IE下鼠标的位置 var myCursorPosition = [0, 0]; myCursorPosition[0] = event.clientX; myCursorPosition[1] = event.clientY; //获取FF下鼠标的位置 var myCursorPosition = [0, 0]; myCursorPosition[0] = event.pageX; myCursorPosition[1] = event.pageY;

/*********************************************************************/

//获取可见区域、窗口的大小IEvar myBrowserSize = [0, 0]; myBrowserSize[0] = document.documentElement.clientWidth; myBrowserSize[1] = document.documentElement.clientHeight; //FFvar myBrowserSize = [0, 0]; myBrowserSize[0] = window.innerWidth; myBrowserSize[1] = window.innerHeight; /*********************************************************************///下面这个应该是CSS的在IE中这样写： #myElement { filter: alpha(opacity=50); } var myObject = document.getElementById("myElement"); myObject.style.filter = "alpha(opacity=80)"; 在Firefox中这样写： #myElement { opacity: 0.5; } var myObject = document.getElementById("myElement"); myObject.style.opacity = "0.5";
