页面搜索的javascript脚本
网上搜索到的页面搜索关键字的脚本大多是这个
<script language= "JavaScript ">
function findInPage(str)
{
var txt, i, found,n = 0;
if (str == " ")
{
return false;
}
txt = document.body.createTextRange();
for (i = 0; i <= n && (found = txt.findText(str)) != false; i++)
{
txt.moveStart( "character ", 1);
txt.moveEnd( "textedit ");
}
if (found)
{
txt.moveStart( "character ", -1);
txt.findText(str);
txt.select();
txt.scrollIntoView();
n++;
}
else
{
if (n > 0)
{
n = 0;
findInPage(str);
}
else
{
alert(str + "---您要找的文字不存在。\n \n请试着输入页面中的关键字再次查找！ ");
}
}
return false;
}
function find_str()
{
if (document.all.find_content.value== " ")
{
alert( "请先输入你要查找的内容 ");
}
else
{
findInPage(document.all.find_content.value);
}
}
</script>
<input type= "text " id= "find_content ">
<input type= "button " name= "Submit " value= "搜索 " onClick= "find_str() ">
但这个脚本如果碰到多个相同的关键词则只能定位到第一个，如何改成像IE页面搜索一样能定位到下一个的效果？
