[英]how to change the url of an anchor link that doesn't have an id or class using JavaScript
我無權訪問包含部分代碼的html文檔。 錨點鏈接不正確,用戶無法訪問信息和工具。 錨鏈接位於<h1>
標記的內部,該標記位於table
內部,該標記位於div
內部。 現在div是唯一具有ID的東西,我無法將jQuery添加到此頁面包裝程序中,因為它已應用於1000多個頁面,所以我不想破壞任何內容。
HTML:
<div id="dashboard-home-content">
<div id="bd-what-next" class="clearfix">
<h2 id="msg_cat_what_next_question">What to do next?</h2>
<div id="what-next-answer">Customize your Personal Page with a story about why you are raising funds for this cause.</div>
</div>
<!-- bd-what-next -->
<div class="ux-block2" id="bd-org-html">
<!-- TODO: Message Catalog this, Fix language -->
<div id="organization_message">
<table style="width: 100%;" border="0">
<tbody>
<tr>
<td>
<h1><a href="change this url" target="_blank"><img src="../cco/images/content/pagebuilder/PC_FAQ_image.jpg" border="0" alt="Personal page image"><br>Participant Centre FAQ</a></h1>
</td>
<td>
<h1><a href="change this url" target="_blank"><img src="../cco/images/content/pagebuilder/PC_pic_image.jpg" border="0" alt="Personal page image"><br>Photo resize tool</a></h1>
</td>
<td>
<h1><a href="change this url" target="_blank"><img src="../cco/images/content/pagebuilder/PC_fundraising_image.jpg" border="0" alt="Personal page image"><br>Fundraising FAQ</a></h1>
</td>
</tr>
</tbody>
</table>
</div>
我知道用jQuery我可以尋找一個特定的元素來添加一個類,例如
$('td:contains("As part of your registration you will receive update emails and support from this program.")').addClass("td_regDetails");
但是我不知道如何用JavaScript做到這一點。
我在想是否有辦法向該錨鏈接添加類或ID,我可以做些類似的事情
var pcfaq = document.getElementById('wrongLinkOne');
pcfaq.href= "[[S8:PC_FAQ_updated.html]]"
(S8呈現html鏈接)。
謝謝您的幫助!
使用document.querySelectorAll()
查找td
內部的所有a
標簽。 遍歷它們,檢查文本是否包含所需內容,然后更改href
。
document.querySelectorAll("td a").forEach(el => {
if (a.textContent.includes("As part of your registration you will receive update emails and support from this program.")) {
a.href = "[[S8:PC_FAQ_updated.html]]";
}
});
