Hi Everyone,
Is there any way that I can use
Substring
Substr
or
startsWith or any function like this in Custom Script.

Hey @ruchin78

In Setup > Custom Scripts, you can use any kind of javascript.

Use javascript string’s substr or slice methods:

  1. String.prototype.substr() - JavaScript | MDN
  2. String.prototype.slice() - JavaScript | MDN

-Anand.

I have already used it, before posting my query on the forum see my code below:
cur_frm.cscript.custom_refresh = function(doc) {

if(doc.item_code.substr(1,3)) {
   cur_frm.set_df_property("revision", "hidden",false);
 }
else
   { cur_frm.set_df_property("revision_no", "hidden",false);
   }

}
See the error below:
Uncaught TypeError: Cannot read property ‘substr’ of undefined

Sorry, a typo in the script but I hope it will not impact the functionality of substring or substr

the correct code is:

cur_frm.cscript.custom_refresh = function(doc) {

if(doc.item_code.slice(1,3)) {
   cur_frm.set_df_property("revision", "hidden",false);
 }
else
   { cur_frm.set_df_property("revision_no", "hidden",true);
   }

}

if(doc.item_code.substr(1,3)==“720”) {
cur_frm.set_df_property(“revision”, “hidden”,false);
}
else
{ cur_frm.set_df_property(“revision_no”, “hidden”,false);
}

and

if(doc.item_code.slice(1,3)==“720”) {
cur_frm.set_df_property(“revision”, “hidden”,false);
}
else
{ cur_frm.set_df_property(“revision_no”, “hidden”,false);
}

and

if(doc.item_code.substring(1,3)==“720”) {
cur_frm.set_df_property(“revision”, “hidden”,false);
}
else
{ cur_frm.set_df_property(“revision_no”, “hidden”,false);
}

all has same error

Can you explain your use case?

To get first three character, use doc.item_code.substr(0,3)
This is working fine.

To hide any field:

 cur_frm.set_df_property("revision", "hidden",true);
