请问 window.location 属性怎么修改为新窗口打开？

[c0427]

以下是一个带有选项卡功能的搜索框代码，怎么修改为 [搜索时新窗口打开搜索页面] ？谢谢。

<SCRIPT language=JavaScript>
function sch(form){
e=document.sel.sq.selectedIndex; //取选定选项的编号
e=document.sel.sq[e].value; //取选定选项的"value"特征值
k=document.sel.k.value; //取搜索关键字
if(document.sel.k.value==""){ //如果没有填入关键字
alert("请输入关键词！"); //则给出提示
document.sel.k.focus(); //将光标移到输入框
return
}
//以下根据选择的内容改变 window.location 属性,进行本窗口导航
if(e=="baidu"){location="https://www.baidu.com/s?&wd="+k;}
if(e=="google"){location="https://www.baiduyaowan.com/webhp?gws_rd=ssl#q="+k;}
if(e=="so"){location="https://www.so.com/s?q="+k;}
if(e=="sogou"){location="https://www.sogou.com/web?query="+k;}
if(e=="bing"){location="http://cn.bing.com/search?q="+k;}
if(e=="zhihu"){location="https://www.zhihu.com/search?type=question&q="+k;}
if(e=="soku"){location="http://www.soku.com/v?keyword="+k;}
if(e=="tmall"){location="https://list.tmall.com/search_product.htm?q="+k;}
if(e=="taobao"){location="https://s.taobao.com/search?q="+k;}
if(e=="jd"){location="http://search.jd.com/Search?keyword="+k;}
if(e=="excite"){location="http://search.excite.com/search.gw?search="+k;}
}
</SCRIPT>

window.open()
中间不能有任何异步的动作，不然会被浏览器阻挡。

window.open('http://xxx','_blank')

@FrankFang128 第二个参数加与不加有何区别

[FrankFang128]

跟 <a> 和 <a target="_blank"> 一样

@edisonator 楼上

[edisonator]

@FrankFang128 不加参数不也是打开新窗口么？但是<a>不带 target 是直接跳转呀

[FrankFang128]

@edisonator 哦对，加了比较好
