Question

如何从＆＃39; group2＆＃39;中删除空格？ div span在页面加载时的类值。这是在页面加载时呈现的html。 span类值不应包含空格（例如：＆＃34; ClassicalStudies＆＃34;而不是＆＃34; Classical Studies＆＃34;）。其他span类值也是如此。

<div class="group2">
<p class="subject-list">
    <span class="Classical Studies">Classical Studies</span>
</p>
<p class="subject-list">
    <span class="Cognitive Science">Cognitive Science</span>
</p>
<p class="subject-list">
    <span class="Computer Engineering">Computer Engineering</span>
</p>
<p class="subject-list">
    <span class="Computer Science">Computer Science</span>
</p>

Answer 1

使用attr()方法进行回调并替换class属性中的所有空格。

＆＃13;

// attr method with callback would iterate over the 
// elements internally and you can update value by returning
$('.group2 span').attr('class', function(i, c) {
  // split by space and then join by empty string
  return c.split(' ').join('');
  // or replace all space by empty string
  // return c.replace(/\s+/g,'');
})
