javascript - 单击第一个按钮时也自动单击第二个按钮

Question

我的点击按钮有问题。我需要的是在单击第一个按钮时自动单击第二个按钮。我创建了一个无法正常工作的示例代码

HTML

<button id="button1" class="btn btn-success">1st button</button>
<a id="button2" class="btn btn-success" href="google.com">2nd button</a>

jQuery

   jQuery(document).ready(function() {
    jQuery('#button1').click(function () {
      jQuery('#button2').click();
   })
   });

这是我的 jdfiddle https://jsfiddle.net/wj8pb9sf/

这段代码片段我已经有一段时间了，它已经证明在这些情况下非常有值(value):

// Simulate event
function fireEvent(node, eventName) {
    // Make sure we use the ownerDocument from the provided node to avoid cross-window problems
    var doc;
    if (node.ownerDocument) {
        doc = node.ownerDocument;
    } else if (node.nodeType == 9){
        // the node may be the document itself, nodeType 9 = DOCUMENT_NODE
        doc = node;
    } else {
        throw new Error("Invalid node passed to fireEvent: " + node.id);
    }

    if (node.dispatchEvent) {
        // Gecko-style approach (now the standard) takes more work
        var eventClass = "";

        // Different events have different event classes.
        // If this switch statement can't map an eventName to an eventClass,
        // the event firing is going to fail.
        switch (eventName) {
            case "click": // Dispatching of 'click' appears to not work correctly in Safari. Use 'mousedown' or 'mouseup' instead.
            case "mousedown":
            case "mouseup":
                eventClass = "MouseEvents";
                break;

            case "focus":
            case "change":
            case "blur":
            case "select":
                eventClass = "HTMLEvents";
                break;

            default:
                throw "fireEvent: Couldn't find an event class for event '" + eventName + "'.";
                break;
        }
        var event = doc.createEvent(eventClass);
        event.initEvent(eventName, true, true); // All events created as bubbling and cancelable.

        event.synthetic = true; // allow detection of synthetic events
        // The second parameter says go ahead with the default action
        node.dispatchEvent(event, true);
    } else  if (node.fireEvent) {
        // IE-old school style, you can drop this if you don't need to support IE8 and lower
        var event = doc.createEventObject();
        event.synthetic = true; // allow detection of synthetic events
        node.fireEvent("on" + eventName, event);
    }
};

它不依赖于 jQuery，允许您模拟一堆有用的事件。只需执行以下操作:fireEvent(document.getElementById('button2'), 'click');。
