How to replace Dynamic content in a string variable.

[adarshs]

Hello all ,

I am trying to replace all the contents present in one variable   in another variable dyamically as below.

var src = g_form.getValue('U_test');

  var src1= g_form.getValue('U_test1');

var src2 = g_form.getValue('U_test2');

var my_new_str = src.replace(/A/g,'M') ;********************This is working fine as it is replacing all 'A' with 'M'.

But i need to replace the content of src1 present in src dynamically with src2 like,

var my_new_str = src.replace(src1 /g,src2 );*******************This is not working.

Tried with other Java functions to replace strings .But it didnt work.

Does anyone know if there is any correct way to do this in Service Now?

Thanks ,

Adarsh

Hi Adarsh,

Use the below code which works for your requirement. You need a regular expression in this case.

var src = g_form.getValue('u_test');

var src1= g_form.getValue('u_test1');

var src2 = g_form.getValue('u_test2');

var exp = new RegExp(src1, 'gi'); //'gi' is for case insensitive replacement and 'g' for case sensitive replacement

var my_new_str = src.replace(exp,src2 );
