Question

我有一个无序列表，每个li元素都有一个图像和一个兄弟输入[type =＆＃34; number＆＃34;]（IMG - ＃），我试图用最高数字的兄弟附加图像val（），当点击一个按钮时...... $（＆＃39;＃guessCheck＆＃39;）

我的HTML代码看起来像这样

 <div id="checkedImageContainer" class="hidden col-md-4">
                <div class="text-center">
                    <h3 style="color:black"><strong>Now rate your favorite Images!!(#1-10)</strong></h3>
                    <ul class="checkedImageList">
<li><image src="pics/hammer.jpg" name="hammer"><input id="rateInput" type="number" value="1" min="1" max="10"><label id="RateButton">Rate</label></li>
<li><image src="pics/hardhat.jpg" name="hardhat"><input id="rateInput" type="number" value="1" min="1" max="10"><label id="RateButton">Rate</label></li>
<li><image src="pics/paintbrush.jpg" name="paintbrush"" name="hammer"><input id="rateInput" type="number" value="1" min="1" max="10"><label id="RateButton">Rate</label></li>
                    </ul>
                    <button id="guessCheck">That's MY Opini0n</button>
                </div>
<ul id="highestRated">
</ul>
</div>

到目前为止，我的jquery中有这个，但是我的代码中出现了我的IMAGE语法错误，我知道src attr是错误的...

$('#guessCheck').on('click', function(){

let highestRating = $("input[type='number']").map(function() {
     return {ele: $(this), val: parseFloat(this.value)};
 }).get().sort((a,b) => {return b.val - a.val;})[0].ele;
 $('#guessImageContainer').removeClass('hidden');
 console.log('removed hidden class on the #highestrated list');
 $('#guessImageContainer').append('<li><img src="' + highestRating.closest('img').attr('src') + '"><input id="guessMyValue" type="text"><button class="text-center" id="finishButton">Finish_Button</button><h2 class="text-center">Now Guess The Name Of The image</h2></li>');

}）;

在这种情况下，我想附加HAMMER img // \

您的代码中存在一些错误：

ID必须是唯一的。将它们改为课堂。
属性选择器必须更改为 [type =＆＃39; number＆＃39;]
正确打开和关闭字符串
对地图结果进行排序
而非最近，您需要上一步
不要在事件处理程序
正确委派您的活动
