Javascript中的错误导致IE中的页面停止运行javascript

Question

在我的网站上，我有一个javascript文件的引用，在IE上，抛出了这个错误：

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;
},

Internet Explorer正在捕获throw，它似乎暂停了其他任何javascript的运行。

我该怎么做才能让错误无法完全停止我页面上的所有内容？

Answer 1

如果你不想抛出异常，为什么要使用throw？ 考虑这一点，如果您想要用于记录目的的异常：

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;
}
