js自动输入

function simulateKeyPress(element, text) {
    for (let i = 0; i < text.length; i++) {
        const event = new KeyboardEvent('keydown', {
            key: text[i],
            bubbles: true,
            cancelable: true
        });
        element.dispatchEvent(event);
    }
}

// 使用示例
const inputElement = document.getElementById('myInput');
simulateKeyPress(inputElement, 'Hello World!');

function setInputValue(element, value) {
    element.value = value;
}

// 使用示例
const inputElement = document.getElementById('myInput');
setInputValue(inputElement, 'Hello World!');

document.addEventListener('DOMContentLoaded', function() {
    const inputElement = document.getElementById('myInput');
    setInputValue(inputElement, 'Hello World!');
});

<input type="text" id="myInput" autocomplete="off" autocorrect="off">
