在这种情况下如何使用每个

Question

我想 .each() 是这种情况的解决方案，我使用带前缀的类，在这种情况下如何使用 .each()？

尝试了很多方法，都没有成功

HTML

<div id="huge_it_slideshow_image_container_1" class="huge_it_slideshow_image_container_1">

JQUERY

$(function(){

      // Change behavior title and description HUGE IT
      var huge_it_title = $( "*[class*='huge_it_slideshow_title_text_']" ).text();
      $( "*[class*='huge_it_slideshow_description_text_']" ).prepend( "<span style='font-weight:bold; text-transform:uppercase;'>" + huge_it_title + "</span><br>" );

    });

将.each() 链接到huge_it_title，其中回调中的this 将是当前DOM 元素；在回调中，您可以使用 .textContent

引用当前元素文本

var huge_it_title = $("*[class*='huge_it_slideshow_title_text_']");
$("*[class*='huge_it_slideshow_description_text_']")
.each(function(index, el) {
  $(this)
  .prepend("<span style='font-weight:bold; text-transform:uppercase;'>" 
           + huge_it_title[index].this.textContent + "</span><br>")
});

您也可以使用.prepend(function) 或.html(function)

$(function() {
  var huge_it_title = $("*[class*='huge_it_slideshow_title_text_']");
  $("*[class*='huge_it_slideshow_description_text_']")
  .prepend(function(index, html) {
      return "<span style='font-weight:bold; text-transform:uppercase;'>" 
             + huge_it_title[index].textContent 
             + "</span><br>" + html
    }).first().css("opacity", 1);
})
