我在href中有六个body标签。我选择了所有链接并修改了所有这些链接。现在我想用修改后的链接代替。我的问题是如何替换确切的href标签
var links = document.getElementsByTagName('a');
var new_str=[];
var new_utm=[];
var arr =[];
var utm_link_with_token = '&utm_source=iconnect&utm_medium=email&utm_campaign={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&emailId={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&codsId={{Account.CODS_External_Id__c}}&utm_term=';
var utm_link_without_token = '?utm_source=iconnect&utm_medium=email&utm_campaign={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&emailId={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&codsId={{Account.CODS_External_Id__c}}&utm_term='
for(var i = 0; i< links.length; i++){
arr.push(links[i].href);
}
console.log(arr);
for(var i = 0; i< arr.length; i++){
if ( (arr[i].indexOf("elqTrackId") > 0) ) {
if ( (arr[i].indexOf("?elqTrackId") > 0) ) {
new_str[i] = arr[i].substring(0, arr[i].indexOf("?elqTrackId"));
if ((new_str[i].indexOf("?ea=") > 0) ){
new_utm[i] = new_str[i].concat(utm_link_with_token);
}
else{
new_utm[i] = new_str[i].concat(utm_link_without_token);
}
}
else if ( (arr[i].indexOf("&elqTrackId") > 0) ) {
new_str[i] = arr[i].substring(0, arr[i].indexOf("&elqTrackId"));
if ((new_str[i].indexOf("?ea=") > 0) ){
new_utm[i] = new_str[i].concat(utm_link_with_token);
}
else{
new_utm[i] = new_str[i].concat(utm_link_without_token);
}
}
}
else if ( (arr[i].indexOf("mailto:") >= 0) || (arr[i].indexOf("tel:") >= 0) ) {
new_str[i] = arr[i];
new_utm[i] = new_str[i];
}
else{
new_str[i] = arr[i];
if ((new_str[i].indexOf("?ea=") > 0) ){
new_utm[i] = new_str[i].concat(utm_link_with_token);
}
else{
new_utm[i] = new_str[i].concat(utm_link_without_token);
}
}
}
console.log("link showed without eloqua tracking id", new_utm);<!DOCTYPE html><html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office">

我建议使用正则表达式替换文本，例如：
let links = document.getElementsByTagName('a');
for(let link of links)
{
let curhref = link.href;
if(curhref.indexOf('http') > -1)
{
link.href = curhref.replace(/(\?|&)elqTrackId=[a-z0-9]+(&elqTrack=true)?/, '');
if(link.href.indexOf('ea=') > -1)
{
link.href += '&utm_source=iconnect&utm_medium=email&utm_campaign={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&emailId={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&codsId={{Account.CODS_External_Id__c}}&utm_term=';
}
else
{
link.href += '?utm_source=iconnect&utm_medium=email&utm_campaign={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&emailId={{Approved_Document_vod__c.Vault_Document_ID_vod__c}}&codsId={{Account.CODS_External_Id__c}}&utm_term=';
}
}
}<center style="width: 100% !important; background-color: #f4f4f4;">
<table cellpadding="0" cellspacing="0" border="0" width="100%" bgcolor="#f4f4f4" style="width:100% !important;">

<td align="center" valign="top" class="">

破坏正则表达式/(\?|&)elqTrackId=[a-z0-9]+(&elqTrack=true)?/：
(\?|&)：查找?或&。 ?是一个特殊字符，因此必须先转义才能使用。elqTrackId=[a-z0-9]+：查找elqTrackId=，后跟任意数量的小写字母a至z或0至9 (elqTrack=true)?：如果有elqTrack=true，也要匹配。括号创建一个捕获组，?表示匹配该组的0或1次出现。
