没有; 自2011年4月6日起,针对Chromium(Chrome的开源代码库)的此功能请求已被拒绝。
这是一个提示输入单词并执行区分大小写的搜索的函数:
var searches = searches || 0;
(function () {
var count = 0,
text;
text = prompt('Search:', '');
if (text == null || text.length === 0) return;
function searchWithinNode(node, re) {
var pos, skip, acronym, middlebit, endbit, middleclone;
skip = 0;
if (node.nodeType === 3) {
pos = node.data.search(re);
if (pos >= 0) {
acronym = document.createElement('ACRONYM');
acronym.title = 'Search ' + (searches + 1) + ': ' + re.toString();
acronym.style.backgroundColor = backColor;
acronym.style.borderTop = '1px solid ' + borderColor;
acronym.style.borderBottom = '1px solid ' + borderColor;
acronym.style.fontWeight = 'bold';
acronym.style.color = borderColor;
middlebit = node.splitText(pos);
endbit = middlebit.splitText(RegExp.lastMatch.length);
middleclone = middlebit.cloneNode(true);
acronym.appendChild(middleclone);
middlebit.parentNode.replaceChild(acronym, middlebit);
count++;
skip = 1;
}
} else if (node.nodeType == 1 && node.childNodes && node.tagName.toUpperCase() != 'SCRIPT' && node.tagName.toUpperCase != 'STYLE') for (var child = 0; child < node.childNodes.length; ++child) child = child + searchWithinNode(node.childNodes[child], re);
return skip;
}
var borderColor = '#' + (searches + 8).toString(2).substr(-3).replace(/0/g, '3').replace(/1/g, '6');
var backColor = borderColor.replace(/3/g, 'c').replace(/6/g, 'f');
if (searches % 16 / 8 >= 1) {
var tempColor = borderColor;
borderColor = backColor;
backColor = tempColor;
}
searchWithinNode(document.body, text);
window.status = 'Found ' + count + ' match' + (count == 1 ? '' : 'es') + ' for ' + text + '.';
if (count > 0) searches++;
})();
