注： 获取Dom元素的Style数组中的指定Style元素复制代码代码如下: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复制代码代码如下: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);}
