Scenario:

Need to avoid the div tags and get data alone from multiline textbox field using JavaScript Client Object Model in SharePoint 2013.

Solution:

We can use a regular expression to achieve it.

The steps in detail as follows:

1. Insert a Script Editor Web Part into the page.

2. This is the complete code, add it into the Script Editor Web Part and save.

<script type="text/javascript">

    ExecuteOrDelayUntilScriptLoaded(retrieveListItems, "sp.js");

    function retrieveListItems() {

        // Create an instance of the current context to return context information
        var clientContext = new SP.ClientContext.get_current();

        //Returns the list with the specified title from the collection
        var oList = clientContext.get_web().get_lists().getByTitle('CustomListName');

        //use CAML to query the top 10 items
        var camlQuery = new SP.CamlQuery();

        //Sets value that specifies the XML schema that defines the list view
        camlQuery.set_viewXml('<View><RowLimit>10</RowLimit></View>');

        //Returns a collection of items from the list based on the specified query
        this.collListItem = oList.getItems(camlQuery);

        clientContext.load(this.collListItem, 'Include(Title,MultipleText)');

        clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));
    }

    function onQuerySucceeded() {

        //Returns an enumerator to iterate through the collection
        var listItemEnumerator = this.collListItem.getEnumerator();
       //Remove div tag use a regular expression
        var reg1 = new RegExp("<div class=\"ExternalClass[0-9A-F]+\">[^<]*", "");
        var reg2 = new RegExp("</div>$", "");

        //Advances the enumerator to the next element of the collection
        while (listItemEnumerator.moveNext()) {
            //Gets the current element in the collection
            var oListItem = listItemEnumerator.get_current();
            alert(oListItem.get_item('MultipleText').replace(reg1, "").replace(reg2, ""));
        }
    }

    function onQueryFailed(sender, args) {

        alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }</script>

Result:<o:p></o:p>
