jQuery：mousedown和click冲突事件

p.onmousedown = function (e) {
    var event = e || window.event;
    if(event.button == 2){
        console.log('right');
    }else if(event.button == 0){
        console.log('left');
    }
}

<span style="color: #000000">var key = false;//设置了一个标志 false为点击事件 ture为鼠标移动事件
var firstTime = 0;
var lastTime = 0;
p.<a href="http://www.php.cn/wiki/1449.html" target="_blank">onclick</a> = function() {
    if(key){
        console.log('click');
        key = false;
    }
}
p.onmousedown = function() {
    firstTime = new Date().getTime();
    console.log('mouseDown');
}
p.<a href="http://www.php.cn/wiki/1459.html" target="_blank">onmouseup</a> = function() {
    console.log('mouseUp');<br/>//鼠标抬起后 记录时间 超过200ms就是移动事件
    lastTime = new Date().getTime();
    if( (lastTime - firstTime) </span><span style="color: #0000ff"><</span><span style="color: #800000"> 200</span><span style="color: #ff0000">){
        key </span><span style="color: #0000ff">= true;    </span><span style="color: #ff0000">}
}</span>
