javascript - 使用jQuery加载图片

我有一个网站，我试图在网站加载时使用jQuery自动点击图片。我正在使用wordpress，并且代码在页脚中实现。该站点是https://mobimania.si/trgovina/ovitek-print-gold-mandala-copy/，实际图片在“ IZBERI MOTIV”部分中。

我有代码，但由于某种原因它不起作用

jQuery("document").ready(function($) {
  setTimeout(function() {
    $("#mCSB_4.fpd-grid.fpd-item>picture").trigger('click');
  }, 10);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<div id="mCSB_4" class="mCustomScrollBox mCS-light mCSB_vertical mCSB_outside" style="max-height: none;" tabindex="0">
  <div id="mCSB_4_container" class="mCSB_container mCS_y_hidden mCS_no_scrollbar_y" style="position:relative; top:0; left:0;" dir="ltr">
    <div class="fpd-grid fpd-grid-contain fpd-padding">
      <div class="fpd-item fpd-hidden" data-title="252105" data-source="/wp-content/uploads/2019/02/252105-e1551204819312.jpg" data-search="252105">
        <picture data-img="/wp-content/uploads/2019/02/252105-e1551204819312-188x300.jpg"></picture>
      </div>
    </div>
  </div>
</div>

最佳答案

您首先需要修复

<script>jQuery function() {

我建议

$(function() {
  setTimeout(function() {
    $("#mCSB_4").find("picture").trigger('click');
  },10);
});

您的选择器有误。您正在尝试单击具有id = mCSB_4和两个.fpd-grid.fpd-item类的某个事物的直接子级

这些都将起作用：


$("#mCSB_4").find("picture").trigger('click');
$("#mCSB_4 > .mCSB_container > .fpd-grid>.fpd-item > picture").trigger('click');
直接后代和
$("#mCSB_4 .mCSB_container .fpd-grid .fpd-item > picture").trigger('click');
仅使用带空格的类


注意这是假定该图片上有一个单击处理程序。

jQuery("document").ready(function($) {
  $("picture").on("click",function() {
    console.log("clicked")
  })
  setTimeout(function() {
    console.log("trying to click")
    $("#mCSB_4").find("picture").trigger('click');
  }, 10);
});

<div id="mCSB_4" class="mCustomScrollBox mCS-light mCSB_vertical mCSB_outside" style="max-height: none;" tabindex="0">

    <div class="fpd-grid fpd-grid-contain fpd-padding">
      <div class="fpd-item fpd-hidden" data-title="252105" data-source="/wp-content/uploads/2019/02/252105-e1551204819312.jpg" data-search="252105">
