Error in Javascript causes page in IE to stop running javascript

On my website, I have a reference to a javascript file, and on IE, this error is thrown:

send: function (data) {
    /// <summary>Sends data over the connection</summary>
    /// <param name="data" type="String">The data to send over the connection</param>
    /// <returns type="signalR" />
    var connection = this;

    if (!connection.transport) {
        // Connection hasn't been started yet
        throw "SignalR: Connection must be started before data can be sent. Call .start() before .send()";
    }

    connection.transport.send(connection, data);

    return connection;
},

That throw is being caught by Internet Explorer, and it appears to halt any other javascript from running.

enter image description here

What can I do so that error doesn't completely halt everything on my page?

Why are you using throw if you don't want to throw the exception? consider this, if you want the exception for logging purposes:

if (!connection.transport) {
    // Connection hasn't been started yet
    setTimeout(function() {
        throw "SignalR: Connection must be started before data can be sent. Call .start() before .send()"; 
    }, 0);
    return;
}
