我有两个链接
<a href="https://ash.confexe.com?ea=gf2014gf#safety">
view now
</a>
<a href="https://ash.com?ea=gFt014gf#context1">
view now
</a>
我想把这些链接分成两片。例如
https://ash.confexe.com?ea=gf2014gf
和
#safety
我的意思是我想在#部分之前和#部分之后制作切片.我得到了第一部分 但我正在为第二部分而苦苦挣扎。代码附在下面。
let links = document.getElementsByTagName('a');
for(let link of links)
{
let curhref = link.href;
if(curhref.indexOf('#') > -1){
if(link.href.indexOf('ea=') > -1)
{
var z = curhref.indexOf('#');
console.log("index no: " +z);
//first portion
var z1 = curhref.substring(0,z);
console.log("First Portion: " +z1);
//second portion
var z2 = curhref.indexOf(""",z1);
var z2=curhref.substring(z1,0);
console.log("second Portion: " +z2);//this should be this what i have after #
}
}

</html>一个简单的解决方案是使用 .split(( 你可以从这里阅读更多关于它的信息
let links = document.getElementsByTagName('a');
for(let link of links)
{
let parts = link.href.split("#");
console.log(parts)

<a href="https://ash.com?ea=gFt014gf#context1">view now</a>

</html>按照这个方式。对字符串使用拆分方法
let links = document.getElementsByTagName('a');
for(let link of links)
{
let curhref = link.href;
if(curhref.indexOf('#') > -1){
if(link.href.indexOf('ea=') > -1)
{
var arr = curhref.split('#')
console.log("First Portion: " +arr[0]);
console.log("second Portion: " +arr[1]);
}
}

<a href="https://ash.com?ea=gFt014gf#context1">view now</a>

</html>const links = document.getElementsByTagName('a');
const linksChunks = links.map(link => link.split('#');
或
const links = document.getElementsByTagName('a');
links.forEach(link => {
const chunks = link.href.split('#');
console.log('Chunk 1: ', chunks[0]);
console.log('Chunk 2: ', chunks[1]);
});
