D3：如何设置“点击”事件和“dbclick”事件同时？ [英] D3: How do I set "click" event and "dbclick" event at the same time?

问题描述

我已经将点击事件切换到一个节点，我也要将一个dbclick事件切换到它。

那么如何同时设置这两个事件呢？

这样可以工作：

  var clickedOnce = false; 
 var timer; 
 
 $（＃test）。bind（click，function（）{
 if（clickedOnce）{
 run_on_double_click（）; 
} 
 timer = setTimeout（function（）{
 run_on_simple_click（parameter）; 
}，150）; 
 clickedOnce = true; 
} 
} 
 
 function run_on_simple_click（parameter）{
 alert（parameter）; 
 alert（simpleclick）; 
 clickedOnce = false; 
} 
 
 function run_on_double_click（）{
 clickedOnce = false; 
 clearTimeout（timer）; 
 alert（doubleclick）; 
} 
  

这是一个工作 JSFiddle

I've toggled click event to a node and I want to toggle a dbclick event to it as well. However it only triggers the click event when I dbclick on it.

So How do I set both events at the same time?

解决方案

You have to do your "own" doubleclick detection

Something like that could work:

var clickedOnce = false;
var timer;

$("#test").bind("click", function(){
    if (clickedOnce) {
        run_on_double_click();
    } else {
        timer = setTimeout(function() {
           run_on_simple_click(parameter);
        }, 150);
        clickedOnce = true;
    }
});

function run_on_simple_click(parameter) {
    alert(parameter);
    alert("simpleclick");
    clickedOnce = false;
}

function run_on_double_click() {
    clickedOnce = false;
    clearTimeout(timer);
    alert("doubleclick");
}

Here is a working JSFiddle
