Find and replace all matching strings within textarea

问题

I have this

var textarea=$('#content'); 
textarea.html(textarea.html().replace("PID","111111")); 

This works partially, but it only finds the first "PID" within the textarea and replaces it to "1111111". There are about 7 others I need to change as well. What I need is a way to find ALL "PID" and replace it with "111111".

Thanks in advance.

回答1:

Use regex to replace all the occurrences in a string. Try this

textarea.html(textarea.html().replace(/PID/g,"111111")); 

回答2:

textarea.html(textarea.html().replace(new RegExp("PID","g"),"111111")); 

the "g" modifier performs a global search.
