问题描述

根据下面的jQuery文档,代码可用于捕获mouseup和mouse down事件。但我的要求有点不同

As per the jQuery docs below code can be used to capture mouseup and mouse down events. But my requirement is bit different

$("#dic").mouseup(function () {

}).mousedown(function () {

});  

但是如何计算mousedown位置与mouseup位置之间的鼠标移动坐标。请帮帮我。如何在mousedown和mouseup之间应用mousemove事件

But How can I calculate mouse moving co-ordinates between mousedown position to mouseup position. Please help me on this. How can I apply mousemove event between mousedown and mouseup

推荐答案

如果你需要捕获拖动过程中鼠标移动的所有点,绑定/取消绑定新的 mousemove 处理程序:

If you need to captue all points the mouse moves through during a drag, bind/unbind a new mousemove handler:

var allPoints = [];
$("#dic").mouseup(function (e) {
    $(this).unbind("mousemove", trackPoints);
}).mousedown(function (e) {
    $(this).bind("mousemove", trackPoints); 
});

function trackPoints(e) {
    allPoints.push({ x: e.pageX, y: e.pageY });
}

这样, trackPoints 将在鼠标停止时开始触发并在其恢复时停止。

This way, trackPoints will start firing when the mouse is down and stop when it goes back up.

您可能还想添加 if(e.which == 1) mouseup mousedown 处理程序的顶部,以便它们执行绑定仅用于鼠标左键,而不是中键或右键。

You may also want to add a if(e.which == 1) to the top of your mouseup and mousedown handlers so that they perform the bind for a left mouse button only, not middle or right buttons.
