Matching and replacing a part of a string..

[Aravinthakumar]

This is my code:

var gr = new GlideRecord('kb_knowledge');

gr.addQuery('number','KB0081186');

gr.query();


while (gr.next()){

gr.u_level_1= gr.u_level_1.replace("old", "new");

//or

//gr.u_level_1= gr.u_level_1.replace(/old/, "new"); //need to know the difference b/w this line and the above line

gr.update();

}

//Also there are many special characters like  below

gr.u_level_1= gr.u_level_1.replace(/old/g, "new");

gr.u_level_1= gr.u_level_1.replace(/old/D, "new");

Need to know the use of /g and /d characters in the replace function.

Can anyone explain more about finding a exact bit of a string and replace with other bit of string.

Hi Aravinth,

it all depends on what you want to replace

/old/g means search for that word in entire string and then replace it; this uses regular expressions

replace("old", "new"); -> this will replace only first occurrence of old to new

\d is used for digit but I don't think you can use that as /old/d

what you want to replace with what?

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.

Hi ankur,

i want to replace like "desktop" with "computer" in all the occurence of the string.

Example string: My desktop_Name was changed yesterday.The new desktop name is Red

To : My computer_name was changed yesterday.The new computer name is Red.

Also can you explain this line --> gr.u_level_1= gr.u_level_1.replace(/old/, "new"); //without any expressions.

Thanks

Hi Aravinth,

gr.u_level_1= gr.u_level_1.replace(/old/, "new");

this will find only 1st occurrence and replace and not the further one

Hi ankur,

How to find and replace as case insensitive?
