Answer 1

希望这会对你有所帮助：

var textDiv = document.getElementById('text');
document.getElementById('shuffle').addEventListener('click',function(){
    var words = textDiv.innerText.split(' ');
    var len = words.length;
    var result = '';
    textDiv.innerText = '';
    for(var i = 0; i < len; ++i){
        var randIndex = Math.floor((Math.random() * (words.length)));
        result += words[randIndex] + ' ';
        words.splice(randIndex, 1);
    }
    textDiv.innerText = result;
}, false);
