如何在html标签中找到字符串并使用javascript / jquery替换

Question

I do not know how to find a string in the html tag and replace it with another one. I will show it on an example.

I have something like that

<a class="test" data-value="/content/dam/tetris-templating/framework/svg/ic-editorial-07.svg"></a>

And I would like to get such an effect

<a class="test"> <img-src="/content/dam/tetris-templating/framework/svg/ic-editorial-07.svg"></a>

Does anyone have any idea? I'm sorry for my level of English.

Answer 1

You can first append the img and then remove the attribute data-value .

See the code below:

 $("a").append(function(){ return '<img src="'+$(this).attr("data-value")+'">'; }).removeAttr("data-value") 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <a class="test" data-value="/content/dam/tetris-templating/framework/svg/ic-editorial-07.svg"></a> 

Answer 2

Assuming that you are new in JavaScript and/or jQuery , I've made a step-by-step example of a solution:

// create a pointer to your anchor
var $yourAnchor = $('.test')

// copy data attribute
var $hdata = $yourAnchor.data('value');

// remove attribute
$yourAnchor.removeAttr('data-value');

// insert html
$yourAnchor.html('<img src="' + $hdata + '">');

Answer 3

 // If It has multiple hyperlink tag then $('a').each(function(){ if($(this).data('value')!=undefined){ $(this).append(function(){ return '<img src="'+$(this).attr("data-value")+'">'; }).removeAttr("data-value"); } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <a class="test" data-value="/content/dam/tetris-templating/framework/svg/ic-editorial-07.svg"></a>
