All other browsre may have supported the opacity CSS property whereas Internext explorer use its properietary alpha filter.
opacity: 0.5; filter: alpha(opacity=50);
where opacity notation is for all other browsers, and filter is for IE.
so the following code shows how you can do a cross browser opacity
<html> <head> <title>Opacity Style Test</title> <script type="text/javascript"> (function () { var div = document.createElement("div"); div.innerHTML = "<div style='opacity:.5;'></div>"; // If .5 becomes 0.5, we assume the browser knows how // to handle native opacity var native = div.firstChild.style.opacity === "0.5"; this.opacityStyle = function (elem, value) { if (typeof value !== "undefined") { if (native) { elem.style.opacity = value; } else { // .filter may not exist elem.style.filter = (elem.style.filter || "") // Need to replace any existing alpha .replace(/alpha\([^)]*\)/, "") + // If we have a number, set that as the value (0-100) (parseFloat(value) + '' == "NaN" ? "" : "alpha(opacity=" + value * 100 + ")"); } elem.style[floatName] = value; } if (native) { return elem.style.opacity; } else { // Only attempt to get a value if one might exist var match = elem.style.filter.match(/opacity=([^)]*)/); return match ? (parseFloat(match[1]) / 100) + "" : ""; } }; })(); window.onload = function () { var div = document.getElementById("div"); // Alerts out '0.5' alert(opacityStyle(div)); }; </script> </head> <body> <div style="opacity:0.5;filter:alpha(opacity=50);" id="div"></div> </body> </html>
