javascript replace function only replaces the first occurance

Question

document.getElementById("Message").innerHTML=document.getElementById("Message").innerHTML.replace("'","%%");

The above statement replaces only the first occurrence of the single quote. Could it be because that I do a submit right after that, and that javascript doesn't wait for the previous statement to be completed before moving on to the next one?

Try using regex /g

.replace(/'/g,"%%")

Change your code as below,

document.getElementById("Message").innerHTML = 
                  document.getElementById("Message")
                          .innerHTML
                          .replace(/'/g,"%%");

To replace globally in javascript you need to add /g to the replacement string.

You should use regular expression in replace.

document.getElementById("Message").innerHTML=document.getElementById("Message").innerHTML.replace(/'/g,"%%");

Use the Global (g) flag in the replace() parameters.

You should use a regular expression and the /g (global) flag. This will replace all occurrences:

document.getElementById("Message").innerHTML=
    document.getElementById("Message").innerHTML.replace(/'/g,"%%");

@ADC Yeah, but it offered a short, ambiguous answer accompanied with zero explanation and really great SEO. Though, I guess I'm just adding to the page rank with my reference. O_o – Pete Sep 26 '12 at 18:06
