Javascript中的错误导致IE中的页面停止运行JavaScript

Question

在我的网站上，我有一个对javascript文件的引用，在IE上，抛出此错误：

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;
},

该throw被Internet Explorer捕获，并且似乎停止了任何其他JavaScript的运行。

我该怎么做才能使错误不会完全停止页面上的所有内容？

Answer 1

如果不想引发异常，为什么要使用throw？ 如果您希望出于记录目的使用异常，请考虑以下事项：

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;
}
