我知道“mousedown”是用户按下鼠标时,“mouseup”是用户松开鼠标时。但我想在用户按下鼠标并按住它直到它释放后监听事件。有任何想法吗?

如果您想要保持状态,那么它将是您处于mousedown事件状态一段时间时的状态。当您按下mousedown而不是mouseup时,此状态存在。因此,您需要获取一个记录事件当前状态的变量。

JS

$('div').on('mousedown mouseup', function mouseState(e) {
    if (e.type == "mousedown") {
        //code triggers on hold
        console.log("hold");
    }
});

尝试这个

将相应的鼠标事件添加到以下功能

mouse = false;
function mousedown()
{
  mouse = true;
  callEvent();
}
function mouseup()
{
  mouse =false;
}
function callEvent()
{
 if(mouse)
 {
   // do whatever you want
   // it will continue executing until mouse is not released


   setTimeout("callEvent()",1);
 }
 else
 return;
}

var setint  = '';
$(document).ready(function() {
var val = 0;
$('#hold').on('mousedown',function (e) {
   clearInterval(setint);
   val = 0;
   setint = setInterval(function () {
       $("#putdata").val(++val);
        console.log("mousehold");
   },50);
});
$('#hold').on("mouseleave mouseup", function () {
   val = 0;
   $("#putdata").val(val);
   clearInterval(setint);
});
});

来自 jquery.com:

HTML:

<p>Press mouse and release here.</p>

脚本:

$("p").mouseup(function(){
    $(this).append('<span style="color:#F00;">Mouse up.</span>');
}).mousedown(function(){
    $(this).append('<span style="color:#00F;">Mouse down.</span>');
});
