jquery - 显示和隐藏一个问题的文本功能。如何删除最初的“少显示”元素？

Question

代码按应有的方式运行。

我很难弄清楚如何最初从显示屏上隐藏“少显示”按钮。

我在这里所做的只是抓住第一段并隐藏其余部分以在单击继续阅读按钮后显示。但是，显示较少按钮最初显示在显示屏上。我想弄清楚如何删除它。我试着用 .html 方法把它拿走，但它根本没有出现。

有什么建议么？

jQuery(function() {

  //Read more / read less text functionality. Add "minimize" to any paragraph of text.
  var wrapPara = jQuery('.minimize p').nextAll().wrapAll('<div class="hide-body">');
  var minimized_elements = jQuery('.minimize > p:first-child');
  var continueReading = '<a href="#" class="btn btn-success mr-3 more">Continue reading</a>';
  var showLess = '<a href="#" class="btn btn-success less">Show less</a>';

  minimized_elements.each(function() {
    jQuery(this).html(
      minimized_elements.text() + '<span>... </span>' + continueReading + " " + showLess
    ).appendTo(".minimize");
  });

  jQuery('a.more', minimized_elements).click(function(event) {
    event.preventDefault();
    jQuery(this).toggle();
    jQuery(this).next().show();
    jQuery(".hide-body").show();
  });

  jQuery('a.less', minimized_elements).click(function(event) {
    event.preventDefault();
    jQuery(this).toggle();
    jQuery(this).prev().show().prev().show();
    jQuery(".hide-body").hide();
    jQuery(".less").show();
  });
});

.hide-body {
  display: none;
}

您希望Show less最初隐藏链接，因此只需style="display:none;"在下面添加它html。

var showLess = '<a href="#" class="btn btn-success less" style="display:none;">Show less</a>';

此外，我认为一旦用户展开该段落，然后单击Show less该hide链接即可。所以我评论了jQuery(".less").show();行。

完整代码如下。你可以测试一下。

jQuery(function() {

  //Read more / read less text functionality. Add "minimize" to any paragraph of text.
  var wrapPara = jQuery('.minimize p').nextAll().wrapAll('<div class="hide-body">');
  var minimized_elements = jQuery('.minimize > p:first-child');
  var continueReading = '<a href="#" class="btn btn-success mr-3 more">Continue reading</a>';
  var showLess = '<a href="#" class="btn btn-success less" style="display:none;">Show less</a>';

  minimized_elements.each(function() {
    jQuery(this).html(
      minimized_elements.text() + '<span>... </span>' + continueReading + " " + showLess
    ).appendTo(".minimize");
  });

  jQuery('a.more', minimized_elements).click(function(event) {
    event.preventDefault();
    jQuery(this).toggle();
    jQuery(this).next().show();
    jQuery(".hide-body").show();
  });

  jQuery('a.less', minimized_elements).click(function(event) {
    event.preventDefault();
    jQuery(this).toggle();
    jQuery(this).prev().show().prev().show();
    jQuery(".hide-body").hide();
    // jQuery(".less").show();  // Commented to hide show less link once it clicked.
  });
});

.hide-body {
  display: none;
}
