我有一根这样的绳子。
var test = "the email body text is <p>the email test is the email tes is the email.</p>
<p><span id="xXmergefield selnameXx5" class="tag mergefield selname" style="background-color: rgba(0, 0, 255, 0.75);" contenteditable="false" **data-replacement="{MERGEFIELD SailName}"**>Sail Name<em id="xXmergefield selnameXx5-remover" class="fas fa-times remover"></em></span></p>"
为了保存，我想要变量test as，
var test = "the email body text is <p>the email test is the email tes is the email.</p>{MERGEFIELD SailName}".
而不是----
<p><span id="xXmergefield selnameXx5" class="tag mergefield selname" style="background-color: rgba(0, 0, 255, 0.75);" contenteditable="false" data-replacement="{MERGEFIELD SailName}">Sail Name<em id="xXmergefield selnameXx5-remover" class="fas fa-times remover"></em></span></p>
-------我想要属性data-replacement only的值-{MERGEFIELD SailName}。
最终结果需要
var test = "the email body text is <p>the email test is the email tes is the email.</p>{MERGEFIELD SailName}".
像这样的？
null
var input = 'the email body text is <p>the email test is the email tes is the email.</p><p><span id="xXmergefield selnameXx5" class="tag mergefield selname" style="background-color: rgba(0, 0, 255, 0.75);" contenteditable="false" data-replacement="{MERGEFIELD SailName}">Sail Name<em id="xXmergefield selnameXx5-remover" class="fas fa-times remover"></em></span></p>'
var test = "the email body text is <p>the email test is the email tes is the email.</p>";
input = input.replace(test,'');
test+=input.match(/data-replacement="(.*?)">/)[1]
console.log(test);
//{MERGEFIELD SailName}
null
const test = `the email body text is <p>the email test is the email tes is the email.</p><p><span id="xXmergefield selnameXx5" class="tag mergefield selname" style="background-color: rgba(0, 0, 255, 0.75);" contenteditable="false" **data-replacement="{MERGEFIELD SailName}"**>Sail Name<em id="xXmergefield selnameXx5-remover" class="fas fa-times remover"></em></span></p>`
const div = document.createElement('div');
div.innerHTML = test.trim();
const attribute = div.querySelector('.tag').getAttribute('**data-replacement');
const result = `${div.innerHTML}${attribute}`;
console.log(result)
