如何获取鼠标点击位置？

我知道我可以通过执行来获取鼠标指针的位置xdotool getmouselocation。我需要的是能够运行并让我知道鼠标指针单击的位置的程序。

答案1

您可以使用GNU Xnee跟踪鼠标事件，然后仅 grep 鼠标按键事件。但是由于鼠标单击事件不包含鼠标位置，因此您应该从先前的事件中存储它或执行外部命令（例如xdotool）来获取当前的鼠标位置。

例子：

$ cnee --record --mouse | awk  '/7,4,0,0,1/ { system("xdotool getmouselocation") }'

它将抓住所有左键单击。更改 awk 命令中的最后一个数字以获取其他键（1 - 鼠标左键，2 - 鼠标中键，3 - 鼠标右键）或删除它以获取所有键。

此外，事件名称在您的系统上可能看起来有所不同。只需运行$ cnee --record --mouse找出它并替换 awk 命令中的该部分即可。

// Set Netscape up to run the "captureMousePosition" function whenever
// the mouse is moved. For Internet Explorer and Netscape 6, you can capture
// the movement a little easier.
if (document.layers) { // Netscape
document.captureEvents(Event.MOUSEMOVE);
document.onmousemove = captureMousePosition;
} else if (document.all) { // Internet Explorer
document.onmousemove = captureMousePosition;
} else if (document.getElementById) { // Netcsape 6
document.onmousemove = captureMousePosition;
}
// Global variables
xMousePos = 0; // Horizontal position of the mouse on the screen
yMousePos = 0; // Vertical position of the mouse on the screen
xMousePosMax = 0; // Width of the page
yMousePosMax = 0; // Height of the page

function captureMousePosition(e) {
if (document.layers) {
    // When the page scrolls in Netscape, the event's mouse position
    // reflects the absolute position on the screen. innerHight/Width
    // is the position from the top/left of the screen that the user is
    // looking at. pageX/YOffset is the amount that the user has 
    // scrolled into the page. So the values will be in relation to
    // each other as the total offsets into the page, no matter if
    // the user has scrolled or not.
    xMousePos = e.pageX;
    yMousePos = e.pageY;
    xMousePosMax = window.innerWidth+window.pageXOffset;
    yMousePosMax = window.innerHeight+window.pageYOffset;
 } else if (document.all) {
    // When the page scrolls in IE, the event's mouse position 
    // reflects the position from the top/left of the screen the 
    // user is looking at. scrollLeft/Top is the amount the user
    // has scrolled into the page. clientWidth/Height is the height/
    // width of the current page the user is looking at. So, to be
    // consistent with Netscape (above), add the scroll offsets to
    // both so we end up with an absolute value on the page, no 
    // matter if the user has scrolled or not.
    xMousePos = window.event.x+document.body.scrollLeft;
    yMousePos = window.event.y+document.body.scrollTop;
    xMousePosMax = document.body.clientWidth+document.body.scrollLeft;
    yMousePosMax = document.body.clientHeight+document.body.scrollTop;
  } else if (document.getElementById) {
    // Netscape 6 behaves the same as Netscape 4 in this regard 
    xMousePos = e.pageX;
    yMousePos = e.pageY;
    xMousePosMax = window.innerWidth+window.pageXOffset;
    yMousePosMax = window.innerHeight+window.pageYOffset;
  }
 }

要检查其是否正常工作，请使用以下代码：

window.status = "xMousePos=" + xMousePos + ", yMousePos=" + yMousePos + ", xMousePosMax=" + xMousePosMax + ", yMousePosMax=" + yMousePosMax
