Options
This page describes options available for the Javascript integration.
As you've seen in the "Getting started" section, Weglot gets initialized through this code:
Weglot.initialize(options)
Where options is a Javascript object with properties defined as follows. Only api_key, (in bold) are required. Weglot uses the api_key to retrieve the link to your project and know what language to show on the language button. You can change options directly in your project settings : https://dashboard.weglot.com/projects/edit
You can also add in the option variable custom parameters that will change the default behavior of the library.

Options

api_key

Your Weglot API Key. Find it in your project settings : https://dashboard.weglot.com/projects/edit.

switchers

A Javascript Array of Objects representing several language switchers on the page
switchers.style
A javascript object describing the default styling of the Weglot language switcher button.
  • switchers.style.with_name (default: true) Display a label text next to each language options. false otherwise
  • switchers.style.full_name (default: true) Display the full name of the language.false to just show the 2-letter language code (eg. FR, ES, DE, EN...)
  • switchers.style.is_dropdown (default: true) Display the language selector as a dropdown. false to show it as a list
  • switchers.style.with_flags (default: true) Display flags on switcher. false otherwise
  • switchers.style.flag_type (default: rectangle_mat) When with_flags is true, you can choose flag style option:
    • shiny
    • square
    • circle
    • rectangle_mat
  • switchers.style.invert_flags (default: true) When is_dropdown is false , the switcher is a list. When you select a language, it has the same behavior as a dropdown: the selected one is always at first. You can set this option to false to disable this behavior and show a fixed list when language changed.
switchers.location
A Javascript Object to define position of your switcher in the page.
  • switchers.location.target
    The CSS selector of the node that the switcher will be a child of
  • switchers.location.sibling
    The CSS selector of the next sibling element of the switcher. null for the last element inside the target
{
switchers: [
{
// Same as button_style at root
style: {
full_name: true,
with_name: true,
is_dropdown: false,
with_flags: true,
flag_type: "circle",
invert_flags: false
},
// Move switcher somewhere in the page
location: {
target: ".header-nav",
sibling: null
}
}
],
}

wait_transition

Default: true trueto prevent content blinking when translating a new page.

hide_switcher

Default: false true to prevent Weglot from creating language switchers, false otherwise. If you set it to true, it's your responsibility to use the Client-side API or link hooks to change languages on the page. It's also useful with the auto-switch option.
Default: false true to translate search queries on the website, false otherwise. You need to add details to select forms to translate with search_forms & search_parameter options

search_forms

Default: "" A comma-separated list of CSS selectors of search form elements to watch for. Useful only if translate_search is true. The form has to send the q parameter for it to work (or the search_parameter, if present)
{
translate_search: true, // Need to be true, otherwise search_forms is useless
search_forms: "form#side-search, form.search-form"
}

search_parameter

Default: "" Name of the input in your form(s) which will send keywords.
Frequently, this is the parameter which contain your keywords in URL.For example, if you have "?q=xxxxx", it will be q
{
translate_search: true,
search_forms: ".my-form", // <input name="q" class=".my-form" />
search_parameter: "q" // it's the name value of your form's search input
}

whitelist

Default: ""
An array of objects containing CSS selectors of elements you want to translate on your page. This will disable all others translations in the same page.
// all other elements won't be translated
{
whitelist: [
{
value: ".my-translated-block"
},
{
value: ".my-another-block"
}
]
}

cache

Default: false
Setting this to true greatly improves user experience by caching Weglot's translations into your visitors' browser. Translations are kept up-to-date asynchronously.

extra_definitions

A Javascript Array of Objects representing extra translation definitions
extra_definitions.selector
A CSS selector to the element(s) you want to target
extra_definitions.attribute
The name of the attribute you'd like to translate
extra_definitions.type
Default: 1
Optional. The WordType of the text that you'd like to translate
{
extra_definitions: [
{
type: 1, // Type of translation, 1 for text, others: https://developers.weglot.com/api/reference#wordtype
selector: "input.someclass[type=text]", // Selector to find element with attribute
attribute: "data-tooltip" // Name of attribute which is translated
}
]
}
Default: false
If you use link hooks you may have some excluded pages, so your links will be inactive with anchors #Weglot-xx. Turn this option to true and we'll remove this HTML links.

extra_merged_selectors

Array of CSS selectors to merge your own HTML nodes in your translations. More information here about translation engine.
{
extra_merged_selectors: ["code", ".wg-merged-nodes"]
}

// EXAMPLE VALUES, NOT DEFAULT
Weglot.initialize({
// Only mandatory value is api_key:
api_key: "wg_1234567897e2ea993d291b571c2ec93b0",
// Next are optionals, often editable on your Weglot dashboard.
// Options written here are concatenated with dashboard options when it's possible, otherwise these one have priority
// Manually design switcher
switchers: [
{
style: {
full_name: true,
with_name: true,
is_dropdown: false,
with_flags: true,
flag_type: "circle",
invert_flags: false
},
// Move switcher somewhere in the page
location: {
target: ".header-nav",
sibling: null
}
}
],
// Automatically redirect visitor by its navigator's language
auto_switch: true,
// If auto switch is true, but you don't have visitor's language, redirect on this language code, otherwise original language
auto_switch_fallback: "en",
// Only translate these blocks
whitelist: [
{
value: ".only-translate-me" // All other elements in the same page won't be translated anymore!
}
],
// Exclude some blocks from translation
excluded_blocks: [
{
value: ".no-translate" // All elements with this class won't be translated
}
],
// Exclude some path in website from translation

// Hide original text before loading translated one, true by default
wait_transition: true,
extra_definitions: [
{
