Question

I have the following script works for the replace with jQuery in innerHTML.

HTML code

<input type="submit" name="replace" id="replace" value="Replace" />

<div class="my_div">Default1 content1</div>
<div class="my_div">Default2 content2</div>

java script

$('#replace').click(function() {
   $('.my_div').html(function( idx, oldHtml){
      return oldHtml.replace(/Default1|content1|Default2|content2/gi, 'symbol1');
   });
});

But I couldn’t modify the script for multiple unique replacement. Example I want to replace

Default1 to symbol1

Default2 to symbol2

content1 to symbol3

content2 to symbol4

the following doesn’t work

$('#replace').click(function() {
   $('.my_div').html(function( idx, oldHtml){
      return oldHtml.replace(/Default1/gi, 'symbol1');
      return oldHtml.replace(/Default2/gi, 'symbol2');
      return oldHtml.replace(/content1/gi, 'symbol3');
      return oldHtml.replace(/content2/gi, 'symbol4');
   });
});

Also I had early script based on id attribute, which is more than 500 replace lines. Is it possible that I can include similar structure in this new jQuery class attribute?

var str=document.getElementById("my_id").innerHTML;
var n=str.replace("Default1","symbol1");
var n=str.replace("Default2","symbol2");
document.getElementById("my_id").innerHTML=n;
}

Thanks a lot, you guys helped me a lot. 🙂

Answer 1

Question 1 :

Replace

return oldHtml.replace(/Default1/gi, 'symbol1');
return oldHtml.replace(/Default2/gi, 'symbol2');
return oldHtml.replace(/content1/gi, 'symbol3');
return oldHtml.replace(/content2/gi, 'symbol4');

with

return oldHtml.replace(/Default1/gi, 'symbol1')
    .replace(/Default2/gi, 'symbol2')
    .replace(/content1/gi, 'symbol3')
    .replace(/content2/gi, 'symbol4');

Question 2 :

Replace

var str=document.getElementById("my_id").innerHTML;
var n=str.replace("Default1","symbol1");
var n=str.replace("Default2","symbol2");
document.getElementById("my_id").innerHTML=n;

with

var $div = $('#my_id');
$div.html(
    $div.html().replace("Default1","symbol1")
    .replace("Default2","symbol2")
);

(if you use jQuery, no need for those getElementById)
