模拟鼠标，点击，在Tampermonkey中的鼠标鼠标序列？

Question

我想模拟整个点击不仅仅是

document.getElementsByClassName()[0].click();

.

我该怎么做？搜索结果似乎是关于处理此类事件，而不是触发它们。

Answer 1

发送鼠标事件。如：

//--- Get the first link that has "stackoverflow" in its URL.
var targetNode = document.querySelector ("a[href*='stackoverflow']");
if (targetNode) {
    //--- Simulate a natural mouse-click sequence.
    triggerMouseEvent (targetNode, "mouseover");
    triggerMouseEvent (targetNode, "mousedown");
    triggerMouseEvent (targetNode, "mouseup");
    triggerMouseEvent (targetNode, "click");
}
else
    console.log ("*** Target node not found!");

function triggerMouseEvent (node, eventType) {
    var clickEvent = document.createEvent ('MouseEvents');
    clickEvent.initEvent (eventType, true, true);
    node.dispatchEvent (clickEvent);
}

如果网页在静态加载的情况下。如果网页是ajax驱动的，请使用一种：

• “正常”按钮单击方法不是在Greasemonkey脚本中工作？
• 选择和激活正确的控制Ajax驱动的网站

小号：
问题代码有一个错误。您需要将类名称传递给该函数。如：

document.getElementsByClassName ("SomeClassName")[0].click();

我改进了 Brock的代码它在它对我的预期工作后一点。

定义：

function simulateMouseClick(targetNode) {
    function triggerMouseEvent(targetNode, eventType) {
        var clickEvent = document.createEvent('MouseEvents');
        clickEvent.initEvent(eventType, true, true);
        targetNode.dispatchEvent(clickEvent);
    }
    ["mouseover", "mousedown", "mouseup", "click"].forEach(function(eventType) { 
        triggerMouseEvent(targetNode, eventType);
    });
}

.

调用示例：

simulateMouseClick(document);

simulateMouseClick(document.querySelector("a[href*='stackoverflow']"));

.

位优化

function fireMouseEvents( query, eventNames ){
    var element = document.querySelector(query);
    if(element && eventNames && eventNames.length){
        for(var index in eventNames){
            var eventName = eventNames[index];
            if(element.fireEvent ){
                element.fireEvent( 'on' + eventName );     
            } else {   
                var eventObject = document.createEvent( 'MouseEvents' );
                eventObject.initEvent( eventName, true, false );
                element.dispatchEvent(eventObject);
            }
        }
    }
}

.

你会像这个一样闪光

fireMouseEvents("a[href*='stackoverflow']",['mouseover','mousedown','mouseup','click']);

.
