替换方法在浏览器中不起作用但在 console.log 中起作用
replace method not working in browser but working in console.log
我正在尝试替换 Wordpress 网站中的多次出现,所以我是这样做的:
window.onload = init;
function init()
{
// get all the divs which have specific class names
let divElems =
document.querySelectorAll(".vc_custom_heading.white.vc_gitem-post-data.vc_gitem-post-data-source-post_title");
// loop on the divs
for(let i = 0 ; i < divElems.length ; i++)
{
// get the first child of the div : a <h2>
let titleElem = divElems[i].childNodes[0];
// get the first child of the title : a <a>
let linkElem = titleElem.childNodes[0];
// get the text content of the link
let text = linkElem.textContent;
// replace the word test by nothing
text = text.replace(/test/g, '');
// all the occurrences of test have been removed in the console.log, but not in browser
console.log(text);
}
};
但奇怪的是,替换方法在 console.log 中工作正常(我可以看到测试词已被删除),但在 浏览器 页面 !
有人有想法吗? :)

您只是在更新变量值,因此它不会更新实际的元素内容。要使其工作,只需更新 textContent
属性.
即可更新元素内容
text = text.replace(/test/g, '');
linkElem.textContent = text;
