检查图像是否不存在然后隐藏div

Question

如果div中有图像,则隐藏div.但如果图像确实存在,那么我需要保持div可见.

但它不起作用.这是我的代码:

HTML:

<table id="FeatureBox">
    <tbody>
    <tr>
      <td>
        <div id="productInfoGrid">
          <div id="ProductIconsTitle">
            <p>PRODUCT FEATURES</p>
          </div><img width="563" height="337" src="http://www.preserveshop.co.uk/images/black-jam-jar-lid-58mm.jpg" alt="http://www.preserveshop.co.uk/images/black-jam-jar-lid-58mm.jpg" style="cursor: -moz-zoom-in"><div style="clear:both;"></div>
        </div>
      </td>
    </tr>
  </tbody>

JQUERY:

if ($("#div#productInfoGrid:not(img)").length) {
    $("#productInfoGrid").hide();
}

Answer 1

if ( !$("#productInfoGrid").has("img") ) {
    $(this).hide();
}

或者更简单

$("#productInfoGrid").not(':has("img")').hide();?
