+1长期鼠标按下和每100ms停在10

Question

我想补充一个每毫秒，如果用户使长mousepress和10停止，

类似的东西？

$('#bar').mousedown(function(){ 
    setInterval(function() { 
     for(i=1; i<11; i++){ 
      $('#foo').val(i); 
     } 
    }, 100); 
});

你可以我们可以使用clearInterval（）和清除时mouseUp事件或当您达到10

var intVal = null; 
var cnt = 0; 
$('#bar').on('mousedown', function() { 
    intVal = setInterval(function() { 
     $('#foo').val(cnt); 
     cnt == 10 ? clearInterval(intVal) : cnt++; 
    }, 100); 
}).on('mouseup', function() { 
    clearInterval(intVal); 
    if (cnt == 10) { 
     cnt = 0 
    } 
});

重构一个位，以避免使用超时和间隔：

var mouse = { 
     interval:null, // reference to setInterval 
     count: 0  // count 
    }; 

// on mouse down, set an interval to go off every 100 ms. Every 
// execution of this interval increases the counter by one. 
// however, clear the interval (automatically) after 1000ms (100ms * 10) 
$('#bar').on('mousedown', function(){ 
    // reset count (Can also fetch it from the input box if you'd like) 
    mouse.count = 0; 
    // establish interval that will run 10 times (with 100ms delay) 
    mouse.interval = setInterval(function(){ 
    // increase count and place new value in the text field 
    $('#foo').val(++mouse.count); 
    // stop interval automatically when it reaches 10 
    if (mouse.count == 10) { 
     clearInterval(mouse.interval); 
    } 
    }, 100); 
}); 

// Stop interval 
// bind to the document to if the user's mouse strays from the button 
// we still catch the event 
$(document).on('mouseup', function(){ 
    if (mouse.interval){ 
    clearInterval(mouse.interval); 
    mouse.interval = null; 
    } 
});

旧版本：

var mouse = { 
     interval:null, // reference to setInterval 
     timeout:null, // reference to setTimeout 
     count: 0  // count 
    }; 

// on mouse down, set an interval to go off every 100 ms. Every 
// execution of this interval increases the counter by one. 
// however, clear the interval (automatically) after 1000ms (100ms * 10) 
$('#bar').on('mousedown', function(){ 
    mouse.count = 0; 
    mouse.interval = setInterval(function(){ 
    $('#foo').val(++mouse.count); 
    }, 100); 
    mouse.timeout = setTimeout(function(){ 
    clearInterval(mouse.interval); 
    }, 100 * 10); 
}); 

// Stop interval 
// bind to the document to if the user's mouse strays from the button 
// we still catch the event 
$(document).on('mouseup', function(){ 
    mouse.interval && clearInterval(mouse.interval), mouse.interval = null; 
    mouse.timeout && clearTimeout(mouse.timeout), mouse.timeout = null; 
});
