替换href链接文本

Question

Is my code correct?

 function replace_stuff() {
  document.body.innerHTML = document.body.innerHTML.replace(/oldtexts/g,'');
 }

I am trying to remove the string "oldtexts" between an a href tag like this <a href ="#">oldtexts</a> but i still see oldtexts and nothing gets replaced

Answer 1

I didn't try this one, but this may work. (uses jQuery)

$('a[href]').each(function(i){
 if($(this).html()=="oldtext") $(this).html(" ");
});

or

$('a[href]').each(function(i){
 $(this).html($(this).html().replace(/regex/g,"blahblah"));//warning : if replaced text contains nothing(""), then this will not work.
});

Answer 2

You have tagged jQuery, so I would suggest to use it:

$(function(){
    $('a').each(function(){
        var $this = $(this);
        $this.html($this.html().replace(/oldtext/g, ''));
    });
});

Answer 3

Use Jquery :)

$(document).ready(function(){
             $('#idofatag').text('replacevalueofoldtexts');
});

if you want to trigger this change on a click of a button,

$(document).ready(function(){
        $('#someButtonid').click(function(){
             $('#idofatag').text('replacevalueofoldtexts');
        });
});

如果您尝试使用/\\b(oldtexts)\\b/g或jQuery .replace什么？

Answer 5

Since you seem to be using jQuery, the cleanest solution seems to be using a function for .html() .

$('a').html(function (index, oldhtml) {
    return oldhtml.replace(/oldtexts/g, '');
});

If you want to write a reusable function, you can do that of course:

function replace_stuff(index, oldhtml) {
   return oldhtml.replace(/oldtexts/g, '');
}

And then you can invoke it on any jQuery object: $('a').html(replace_stuff); .
