Question

我正在尝试以编程方式点击google calendar page上的某个日期范围按钮（日，周，月，...）。我以编程方式触发按钮回调的尝试都失败了。值得注意的是，按钮的html结构实际上是一个带有附加事件监听器和几个子div的div（我在下面发布）。

我尝试过：

我还能做些什么来触发按钮的回调吗？有没有其他方法可以模仿用户按下它？为简单起见，我们假设我的脚本如下所示：

From: Example Account <example1@example.com>
To: <example2@example.com>
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

Here is a long test message that will probably cause some words to wrap in =
strange places.

该按钮具有以下html结构：

var month = document.getElementsByClassName("goog-inline-block goog-imageless-button goog-imageless-button-collapse-left goog-imageless-button-collapse-right")[1];

// (1)
month.click();    

// (2)
var click = new Event("click", {"bubbles":true, "cancelable":false});
month.dispatchEvent(click);

// (3)
var over = new Event("mouseover", {"bubbles":true, "cancelable":false});
var down = new Event("mousedown", {"bubbles":true, "cancelable":false});
var up = new Event("mouseup", {"bubbles":true, "cancelable":false});
month.dispatchEvent(over);
month.dispatchEvent(down);
month.dispatchEvent(up);

// (4)
coords = month.getBoundingClientRect(); 
    // I repeated 2 & 3, but set the event's clientX & clientY attributes
    var click = new Event("click", {"bubbles":true, "cancelable":false});
    click.clientX = coords.left + n // n is some offset within coords.left & coords.right
    click.clientY = coords.top + m // m is some offset within coords.top & coords.bottom
    month.dispatchEvent(click);

// (5)
// Tried using analogous methods in JQuery
var $month = // jquery selector producing month btn
$month.trigger("click");

// (6)
// Repeated 1-5 on the child elements
