我试图找到一种方法,使我的程序可以在鼠标滚动到某个特定框时确认该框内的文本。我不知道该怎么做,因为文本不是对象或任何东西,文本是根据框的位置写入框的。我认为,如果盒子是单独的元素,这会更容易,但是我不知道如何设置它。这是到目前为止我得到的。

您必须在drawBoxes
中进行盒装测试。当前鼠标位置可以通过变量mouseX
和mouseX
获得。测试鼠标是否在框中。如果鼠标在框中,则返回一个字典,其中包含文本和鼠标位置。否则返回mouseY
。例如:(我不知道您要显示哪个文本,因此您可能需要调整文本)
mouseY
如果null.
返回一个对象,则必须存储该对象(function drawBoxes(calX, calY) {
// [...]
if (calX < mouseX && mouseX < calX + 78.5 && calY < mouseY && mouseY < calY + 70 ) {
return { text: calReadableDate, x:mouseX, y: mouseY };
}
return null;
}
)。在日历上方drawBoxes
的末尾绘制文本:
infoText
请参见示例:
drawCalendar
function drawCalendar() {
// [...]
let infoText = null
while (firstDayCal <= daysInMonth) {
let text = drawBoxes(calX, calY);
if (text) {
infoText = text
}
cDate.setDate(firstDayCal);
}
if (infoText) {
text(infoText.text, infoText.x, infoText.y);
}
}
