复制代码 代码如下:

//高亮显示搜索到的关键字

function HeightLight(Keyword)

{

//文本选择器

var TextRange;

//是否找到

var Found=false;

//找到的次数

var Count = 0;

TextRange = document.body.createTextRange();

Found = TextRange.findText(Keyword);

if (Found)

{

Count++;

}

while (Found && Count > 0)

{

TextRange.pasteHTML('<span>' + Keyword + '</span>');

//将滚动条定位到第一次查到的视口范围内

if(Count==1)

{

TextRange.scrollIntoView();

}

//继续查找

Found = TextRange.findText(Keyword);

if (!Found)

{

Count = 0;

}

else

{

Count++;

}

}

}

//正则式法

function highLight(ele,keys)

{

var reg = new RegExp("(" + keys.replace(/,/,"|") + ")","g");

ele.innerHTML = ele.innerHTML.replace(reg,"<font color="red">$1</font>");

}
