Question

嗨，所以我的手风琴上有div：

    <a href="#collapse17" data-quickedit-field-id="paragraph/17/field_section_title/en/default" class="field field--name-field-section-title field--type-string field--label-hidden accordion-toggle field--item" data-parent="#accordion" data-toggle="collapse">
  <h2><strong>Accordion Header</strong></h2>
</a>
<div id="collapse17" data-quickedit-field-id="paragraph/17/field_section/en/default" class="field field--name-field-section field--type-entity-reference-revisions field--label-hidden panel-collapse collapse field--item">
    <div class="panel-body">
        <div data-quickedit-field-id="paragraph/10/field_diagram_title/en/default" class="field field--name-field-diagram-title field--type-string field--label-hidden p-1 section-title-diagram field--item background-purple" id="div">INDEPENDENT LEARNING12</div>
    </div>
</div>

当悬停在inspect元素上的div元素上时，高度为20px。但是我的jQuery：

    $('.section-title-diagram').each(function(){
  var $div = $("#div");
    var height = $div.height();
  var text = $div.text();
  console.log("Height: ", height);
  console.log("Text: ", text);
});

为0。

var text = $(this).text();
console.log(text);

它确实正确吐出INDEPENDENT LEARNING12。我被困在为什么我的div的高度为0的问题上。我尝试了多种方法，但无济于事。任何帮助将不胜感激。

Answer 1

因为您设置了

<xsl:template match="@styleCode" name="specialStyleCodeAttr"  >
<xsl:template match="@styleCode" name="styleCodeAttr">
<xsl:template match="v3:tfoot" name="flushtablefootnotes">
<xsl:template match="v3:tfoot"/>

在您的CSS中

更改为display：block

或在您的jquery代码中设置.collapse { display: none; }。

$('#collapse17').on('shown.bs.collapse', function(){
var diagram_title = $(this).find('.section-title-diagram');
  $(diagram_title).each(function(){
    var $div = $("#div");
    var height = $div.height();
    var text = $div.text();
    console.log("Height: ", height);
    console.log("Text: ", text);
  });
});

元素的高度为0px
