在Tampermonkey中模拟mousedown，click，mouseup序列？ [英] Simulating a mousedown, click, mouseup sequence in Tampermonkey?

问题描述

我想模拟整个点击而不仅仅是

I would like to simulate a whole click not just

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

我该怎么做？搜索结果似乎都是关于处理此类事件，而不是触发它们。

How do I do that? Search results all seem to be about handling such events, not triggering them.

推荐答案

发送鼠标事件。像这样：

Send mouse events. Like so:

//--- 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);
}

如果网络有效页面已静态加载。如果网页是AJAX驱动的，请使用以下技术：

• "正常"按钮点击方法在Greasemonkey脚本中不起作用？


• 在AJAX驱动的网站上选择并激活正确的控件

• "Normal" button-clicking approaches are not working in Greasemonkey script?
• Choosing and activating the right controls on an AJAX-driven site

注意：

问题代码有错误。您需要将类名传递给该函数。像这样：

Beware:
The question code has an error. You need to pass a class name to that function. Like so:

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