# API for the web





If Grammalecte is installed by the user on his browser (like Firefox or Chrome), you can call
several functions for a better integration of grammar checking for your website. This is mostly usefull
if your use a non-standard textarea.





















### Detecting if Grammalecte API is here

Every call to the Grammalecte API will be done via an object called `oGrammalecteAPI`.

    if (typeof(oGrammalecteAPI) === "object") {
        ...
    }


### Disabling the Grammalecte button (the spinning pearl)

By default, Grammalecte inserts a button (a spinning pearl) on each textarea node and editable node (unless the user disabled it).
You can tell Grammalete not to create these buttons on your text areas with the property: `data-grammalecte_button="false"`.


### Open the Grammalecte panel for a node

If you have disabled the spinning buttons, you may launch the Grammalecte panel with your custom button

    oGrammalecteAPI.openPanelForNode("node_id")
    oGrammalecteAPI.openPanelForNode(node)

The node can be a textarea, an editable node or an iframe.
If the node is an iframe, the content won’t be modified by Grammalecte.

# API for the web

## Using the Grammalecte API for the web

**With Grammalecte 1.8+.**

If Grammalecte is installed by the user on his browser (like Firefox or Chrome), you can call
several functions for a better integration of grammar checking for your website. This is mostly usefull
if you use non-standard textareas.

You can:

- disable the Grammalecte button (spinning pearl),

- launch the Grammalecte panel with custom button (or when you think it’s necessary),

- get the modified text via events (instead of having the node content directly modified),

- get raw results (list of errors) of grammar checking and spell checking,

- get spelling suggestions for a wrong word.


### How it works

Usually, webpage scripts can’t call methods or functions of browser extensions.

The Grammalecte API is injected within your webpage, with methods launching events that Grammalecte is listening. When Grammalecte receives one of these events, it launches the requested tasks. Results may be sent via events on webpage nodes.


### Detecting if Grammalecte API is here

Every call to the Grammalecte API will be done via an object called `oGrammalecteAPI`.

    if (typeof(oGrammalecteAPI) === "object") {
        ...
    }


### Disabling the Grammalecte button (the spinning pearl)

By default, Grammalecte inserts a button (a spinning pearl) on each textarea node and editable node (unless the user disabled it).
You can tell Grammalete not to create these buttons on your text areas with the property: `data-grammalecte_button="false"`.


### Open the Grammalecte panel for a node

If you have disabled the spinning button, you can launch the Grammalecte panel with your custom button.

    oGrammalecteAPI.openPanelForNode("node_id")
    oGrammalecteAPI.openPanelForNode(node)

The node can be a textarea, an editable node or an iframe.
If the node is an iframe, the content won’t be modified by Grammalecte.

### Parse a node and get errors

    oGrammalecteAPI.parseNode("node_id")
    oGrammalecteAPI.parseNode(node)

The node can be a textarea, an editable node or an iframe. The node must have an identifier.
Results will be sent with a succession of events at the node.

    node.addEventListener("GrammalecteResult", function (event) {
        if (event.detail.sType  &&  event.detail.sType == "proofreading") {
            let oResult = event.detail.oResult; // null when the text parsing is finished
            ...
        }
    }

    oGrammalecteAPI.parseNode("node_id")
    oGrammalecteAPI.parseNode(node)

The node can be a textarea, an editable node or an iframe. The node must have an identifier.
Results (for each paragraph) will be sent in a succession of events at the node.

    node.addEventListener("GrammalecteResult", function (event) {
        if (event.detail.sType  &&  event.detail.sType == "proofreading") {
            let oResult = event.detail.oResult; // null when the text parsing is finished
