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];
}
}
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);
}
