appendChild不是使用$ .confirm（）的函数

Question

好日子，我正在努力解决这个问题。我花了一天时间试图解决这个问题，但对我来说没有运气。

我试图在$ .confirm（）上的onContentReady函数中追加一个孩子，但似乎对我不起作用。这是代码

HTML

<button onclick="btnclick()">click</button>

的Javascript

 function btnclick() {
    // body...
    $.confirm({
    title:'test',
    content: '<div class=".confirm_body"> </div>',
    onContentReady:function() {

        var body = this.$content.find('.confirm_body');

        var h3 = document.createElement('h3');
        h3.appendChild(document.createTextNode("child"));
        body.appendChild(h3);
    }
   });
  }

例外

jquery.min.js:2 jQuery.Deferred exception: body.appendChild is not a function TypeError: body.appendChild is not a function
    at Jconfirm.onContentReady (http://localhost/NMSCST_CLINIC_INFORMATION_SYSTEM/:154:8)

    at k (http://localhost/NMSCST_CLINIC_INFORMATION_SYSTEM/assets/vendor/jquery/jquery.min.js:2:29882) undefined
r.Deferred.exceptionHook @ jquery.min.js:2

我的代码没有显示孩子。

我该怎么办？请帮忙

我猜你的选择器在else if (userGuess === computerSelection) { //Change from else if --> if wins++; alert('The force is strong with you!'); guessesLeft = 10; guessesSoFar = []; computerSelection = computerChoices[Math.floor(Math.random() * computerChoices.length)]; } else if (guessesLeft === 0) { losses++; alert('Better luck next time!'); guessesLeft = 10; guessesSoFar = []; computerSelection = computerChoices[Math.floor(Math.random() * computerChoices.length)]; } // transfers info into the html var html = "<p id='wins'>Intuitive<br>Victories:<br>" + wins + "</p>" + "<p id='losses'>Incorrect<br>Guesses:<br>" + losses + "</p>" + "<p id='attempts'>Remaining<br>Attempts:<br>" + guessesLeft + "</p>" + "<p id='guesses'>Predictions:<br> " + guessesSoFar.join(", ") + "</p>"; document.querySelector('#game').innerHTML = html; 中不正确，如果this.$content.find('confirm_body')是confirm_body元素，则使用id，例如，

body是一个jQuery对象，而不是DOM对象，所以你应该使用

body.append($(h3));

最好保持一致性，坚持使用所有jQuery方法，而不是混合原生DOM元素和jQuery对象。
