Is it possible to get ALL of the styles for an object using JavaScript? Something like:
main.css
-------
#myLayer {
position: absolute;
width: 200px;
height: 100px;
color: #0000ff;
}
main.js
-------
var ob = document.getElementById("myLayer");
var pos = ob.(getPosition);
// Pos should equal "absolute" but
// ob.style.position would equal null
// any way to get absolute?
You are talking about what is known as Computed Style, check out these article on how to get it:
From the last article, here is a function:
function getStyle(oElm, strCssRule){
var strValue = "";
if(document.defaultView && document.defaultView.getComputedStyle){
strValue = document.defaultView.getComputedStyle(oElm, "").getPropertyValue(strCssRule);
}
else if(oElm.currentStyle){
strCssRule = strCssRule.replace(/\-(\w)/g, function (strMatch, p1){
return p1.toUpperCase();
});
strValue = oElm.currentStyle[strCssRule];
}
return strValue;
}
How to use it:
CSS:
/* Element CSS*/
div#container{
font: 2em/2.25em Verdana, Geneva, Arial, Helvetica, sans-serif;
}
JS:
var elementFontSize = getStyle(document.getElementById("container"), "font-size");
