JS.elementGetStyle(element, style)应用示例

注： 获取Dom元素的Style数组中的指定Style元素

代码如下：

function elementGetStyle(element, style) { 
var value = null; 
if (element.style) { 
value = element.style[style]; 
} 
if (!value) { 
if (document.defaultView && document.defaultView.getComputedStyle) { 
var css = document.defaultView.getComputedStyle(element, null); 
value = css ? css.getPropertyValue(style) : null; 
} else if (element.currentStyle) { 
value = element.currentStyle[style]; 
} 
} 


/** DGF necessary? 
if (window.opera && ['left', 'top', 'right', 'bottom'].include(style)) 
if (Element.getStyle(element, 'position') == 'static') value = 'auto'; */ 


return value == 'auto' ? null : value; 
}

注：选定的Dom元素以color颜色高亮0.2s

代码如下：

function UiWebhighlight(element,color) { 
if (!element) {return} 
var highLightColor = "yellow"; 
if (color) {highLightColor = color} 
if (element.originalColor == undefined) { // avoid picking up highlight 
element.originalColor = elementGetStyle(element, "background-color"); 
} 
elementSetStyle(element, {"backgroundColor" : highLightColor}); 
window.setTimeout(function () { 
try { 
//if element is orphan, probably page of it has already gone, so ignore 
if (!element.parentNode) { 
return; 
} 
elementSetStyle(element, { "backgroundColor": element.originalColor }); 
} catch (e) { } // DGF unhighlighting is very dangerous and low priority 
}, 200); 
}
