cocoscreator html5,Cocos Creator H5支持剪贴板复制功能

很简单，在任意类内设置函数：

webCopyString(str:string){

console.log('复制ing');

var input = str + '';

const el = document.createElement('textarea');

el.value = input;

el.setAttribute('readonly', '');

// el.style.contain = 'strict';

el.style.position = 'absolute';

el.style.left = '-9999px';

el.style.fontSize = '12pt'; // Prevent zooming on iOS

const selection = getSelection();

var originalRange = null;

if (selection.rangeCount > 0) {

originalRange = selection.getRangeAt(0);

}

document.body.appendChild(el);

el.select();

el.selectionStart = 0;

el.selectionEnd = input.length;

var success = false;

try {

success = document.execCommand('copy');

} catch (err) {}

document.body.removeChild(el);

if (originalRange) {

selection.removeAllRanges();

selection.addRange(originalRange);

}

if(success){

console.log("复制成功");

}else{

console.log("复制失败");

}

return success;

}

调用时直接输入

this.webCopyString(json)

看输出状态是否成功， firefox可以执行
