问题描述

如何将文本从span标签添加到data-attr?

How to add text from span tag to data-attr?

示例:
我有这个代码

Example:
I have this code

<div class="clearfix colelem" id="u92-5"><!-- content -->
     <p>Icon<span id="u92-2">iconsymbol</span></p>
    </div>

我想将iconsymbol添加到相同元素的data-attr =iconsymbol"中，例如:

And I want to add iconsymbol to data-attr="iconsymbol" of the same element like a:

<div class="clearfix colelem" id="u92-5" data-attr="iconsymbol"><!-- content -->
         <p>Icon<span id="u92-2">iconsymbol</span></p>
        </div>

是的，它将与所有带有title ="icon"

Yes and it will be with all elements which has a title="icon"

<script>	
    $( document ).ready(function() {
	    $("[title*='icon']").attr('data-attr',function(){ 
   // I don't know
        }).removeAttr('title');
    });
</script>

你知道怎么做吗? 所以我知道这很简单，但是我是jquery的新手，需要您的帮助.
我希望你能理解我的问题.

Do you know how to do it? So I know it is very simple but I am new in jquery and I need in your help.

推荐答案

下面是一个适合您的示例.您可能有几种方法可以实现此目标，但这有望使您入门.请参阅附件中的JSFiddle，以查看此示例的作用

Here is an example that should work for you. There is probably a few ways you can pull this off, but this should hopefully get you started. Please see the attached JSFiddle to see this example in action

$(function() {
    $('[title*="icon"] span').each(function(){
        $(this).parent().closest('div').attr('data-attr', $(this).text())
    });
});

这是您也可以执行此操作的另一种方式

Here is another way you can do this as well

$('[title*="icon"]').each(function(){
    $(this).attr('data-attr', $(this).children().closest('span').text());
});
