Tip

The replace() method as used in the above example replaces only the first

occurrence of the search string. To replace every occurrence of a search string in a

given string, use a regular expression. In the following line of code, the regular

expression /@product@/g makes replace() search for all occurrences of the string

@product@ in the label string:

label = label.replace(/@product@/g, record.tables.detail

[i].fields['product']);

In this example, @product@ is a pattern (to be used in a search) and g is a modifier (to

find all matches rather than stopping after the first match). For more information about

possible regular expressions, see https://www.w3schools.com/js/js_regexp.asp.

The script in this how-to: Translate and replace script uses the replace() method with a

regular expression.

Replace several placeholders in one script

Suppose there are 20 different placeholders in a postcard (for the address, account and

customer details, a promo code, the due date, discounts, a link to a personalized landing page

etc.). Typically this would require 20 queries. Even after optimizing these scripts by using an ID

as selector for those scripts, there are still 20 scripts, 20 queries to run.

If there was only one query, one single script to do all the work, the output could be generated

much faster. Reducing the number of scripts improves the performance of the template. How to

do this?

First, wrap the content that contains all of the placeholders in one (inline) Box and give that Box

or Span an ID (on the Attributes pane). Next, create a script that uses that ID as selector. Then

replace all placeholders in the script and put the content back in the template.

This is similar to working with snippets, but in this case the element is extracted from the actual

template.

Example

The following script replaces all of the placeholders on a postcard. It takes advantage of the

JavaScript replace() command. Assuming that the ID of the block that requires personalization

is promoblock, the script has to have its selector set to #promoblock.
