如何遍历div并找到最近的跨度并为每个跨度添加不同的东西？

Question

For example say I had the following HTML:

<div class="div-style">div text</div> <span>span text</span>
<div class="div-style">another div</div> <span>another span</span>
<div class="div-style">hello</div> <span>world</span>

Now what I want to do is: (using jQuery)

1. Go to each <div> with the class 'div-style'
2. Find the following <span>
3. Append the current <span> 's text to the span (in effect repeating the span text within the span text, so the first span would display 'span textspan text')

Answer 1

Here you go: https://jsfiddle.net/rg9zanks/

$('.div-style + span').each(function() {
  var span = $(this)
  span.after('<span>' + span.text() + '</span>')
})

You can take advantage of the + selector to avoid using the .next() function.

1. Select spans that follow elements with the class .div-style
2. Loop through using .each() , create a new span after the selected spans using after() , and populate it with the same text using .text() .

Answer 2

Literally a one-liner with jQuery, a little something like this:

 $(".div-style + span").html(function(i,v) { return v + v; }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div class="div-style">div text</div> <span>span text</span> <div class="div-style">another div</div> <span>another span</span> <div class="div-style">hello</div> <span>world</span> 

Further reading:

• The + next sibling selector
• Passing a function to the .html() method (or you could use the .text() method instead)

Answer 3

 $('.div-style').each(function(){ var t = $(this).next('span').text(); $(this).next('span').text($(this).next('span').text() + t); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="div-style">div text</div> <span>span text</span> <div class="div-style">another div</div> <span>another span</span> <div class="div-style">hello</div> <span>world</span> 

Try this

Answer 4

 $('.div-style').each(function(i, node){ var nextSpan = $(node).next(); nextSpan.append(nextSpan.html()); }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="div-style">div text</div> <span>span text</span> <div class="div-style">another div</div> <span>another span</span> <div class="div-style">hello</div> <span>world</span> 

Answer 5

$(function () {
   $("div.div-style").next('span').each(function () {
      $(this).append($(this).text());
   });

});
