从Google Chrome扩展程序将文字复制到剪贴板可以通过以下步骤实现:
以下是一个示例代码:
manifest.json:
{
"manifest_version": 2,
"name": "Copy to Clipboard",
"version": "1.0",
"permissions": [
"clipboardWrite"
],
"browser_action": {
"default_popup": "popup.html"
},
"icons": {
"16": "icon.png",
"48": "icon.png",
"128": "icon.png"
}
}
popup.html:
<!DOCTYPE html>
<html>
<head>
<title>Copy to Clipboard</title>
<script src="popup.js"></script>
</head>
<body>
<button id="copyButton">Copy Text</button>
</body>
</html>
popup.js:
document.getElementById('copyButton').addEventListener('click', function() {
var textToCopy = 'Hello, World!'; // 要复制的文本
var textarea = document.createElement('textarea');
textarea.value = textToCopy;
document.body.appendChild(textarea);
textarea.select();
document.execCommand('copy');
document.body.removeChild(textarea);
});
这样,当用户点击扩展程序的按钮时,文本"Hello, World!"将被复制到剪贴板中。
