未在jquery/json滑块中加载图像,jquery,json,slider,Jquery,Json,Slider,我想用外部json文件创建jquery滑块,滑块工作正常,但当页面加载时,只有滑块的按钮出现,点击按钮后图像出现,有人能解决问题吗 HTML <div id="update"> </div> <!--div block which is to be updated by jquery ---> <script src=" https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.2/jquery.min.js

我想用外部json文件创建jquery滑块,滑块工作正常,但当页面加载时,只有滑块的按钮出现,点击按钮后图像出现,有人能解决问题吗

HTML

<div id="update">

</div>
<!--div block which is to be updated by jquery --->

<script src=" https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.2/jquery.min.js "></script>
<script>
    $(document).ready(function () {
        $.getJSON('data.json', function (data) {
            var output = '<div class="slideshow-container">';
            $.each(data.data, function (key, value) {
                output += '<div class="mySlides fade">';
                output += '<h3 class="numbertext"> Location:   ' + value.location + '</h3>';
                output += '<img src="' + value.links.logo2x + '" style="width:100%;"/>';
                output += '<div class="text"> Name:   ' + value.name + '</div>';
                output += '<div class="desc">' + value.description + '</div>';
                output += '</div>'; /*myslides*/
            });
            output += '<a class="prev" onclick="plusSlides(-1)">' + '&#10094;' + '</a>';
            output += '<a class="next" onclick="plusSlides(1)">' + '❯' + '</a>';
            output += '</div>';
            $('#update').html(output);
        });
    });
“仅在页面上加载”按钮出现

点击按钮后,图像加载


这是正常的,因为在您的函数
showselides
中,您使用for循环隐藏了所有img:请尝试

function showSlides(n) {
    var i;
    var slides = document.getElementsByClassName("mySlides");
    var dots = document.getElementsByClassName("dot");
    if (n > slides.length) {
       slideIndex = 1
    }
    if (n < 1) {
       slideIndex = slides.length
    }
    for (i = 0; i < slides.length; i++) {
       slides[i].style.display = "none";
    }
    slides[n].style.display = "block";
}

$(文档).ready(函数(){
输出=”;
输出+='';
输出+='位置:';
输出+='';
输出+='';
输出+='';
输出+='';/*myslides*/
输出+='';
输出+='位置:';
输出+='';
输出+='';
输出+='';
输出+='';/*myslides*/
输出+=''+''和#10094;'+'';
输出+=''+'❯' + '';
输出+='';
$('#update').html(输出);
showThis();
});

请帮助我无法解决此问题,但现在所有图像都没有加载,只有按钮正在加载。您可以创建一个片段或处理您的问题吗?您是否已将函数放入document.ready()中?如果没有,请插入它,但是我如何创建fiddle,因为所有数据都来自json文件否,因为函数是普通javascript,但html嵌入到jquery中
