js 得到所有text值

// 获取页面上所有的元素
const allElements = document.querySelectorAll('*');

// 遍历所有元素并获取它们的文本内容
allElements.forEach(element => {
    console.log(element.textContent);
});

const bodyText = document.body.innerText;
console.log(bodyText);

function getTextFromElement(element) {
    let text = '';
    for (let child of element.childNodes) {
        if (child.nodeType === Node.TEXT_NODE) {
            text += child.textContent;
        } else if (child.nodeType === Node.ELEMENT_NODE) {
            text += getTextFromElement(child);
        }
    }
    return text;
}

const allText = getTextFromElement(document.body);
console.log(allText);
